Is this Valve Clearence Remains Same for EFi engine as well ?

Yes I beleive so, cant see a reason why it would change ,its the same engine after all

The 2021 version due to new emission norms BS6 aka Euro5 the engine runs even leaner = hotter.

It may well have changed the values for the outlet at least. I will inquire with my dealership.

At the 500km inspection they probably dont do much, otherwise they would charge more!

well, this is for a 650 interceptor 500km inspection done in Austria but my guess is the difference is small. For that money you could buy half a new engine here.

that is 895 AU$ for you.

How to adjust the valves on a royal enfield motorcycle

An English made tool designed specifically for the Himalayan. Allows you to adjust the tappet whilst holding the locknut still, and then holding the tappet adjustment while tightening the locknut. A thoughtful tool that makes adjusting the tappets and easy job.

How to adjust the valves on a royal enfield motorcycle

Representing the peak of Royal Enfield Motorcycles evolution, was the 750 Interceptor. This 1963 Royal Enfield Interceptor Mark I was at the first year for the 750 engine. This one happened to be at the 2011 Clubman’s All-British Weekend.

THE EARLY DAYS
Royal Enfield Motorcycles were not the best-selling Classic British Motorcycles, but they were often unique and interesting. Like so many British Motorcycle Companies at the time, Royal Enfield started out making bicycles in 1893 as the Enfield Manufacturing Company Ltd. By 1899, they’d build their first Quadricycle with a DeDion engine. They added “Royal” to the Enfield name. In 1912 they started racing with their Royal Enfield Model 80, powered by a 770cc JAP V-twin, enjoying some success at the Isle of Man TT and Brooklands.

WORLD WAR I & AFTER
WWI brought rich contracts from both the British War Department and Imperial Russia for 3 different models: a 225cc two-stroke; a 425cc V-twin; and an 8hp sidecar rig with a Vickers machine gun mounted on it. With war’s end, Royal Enfield Motorcycles concentrated on the civilian market with a new 976cc V-twin in 1921 and their first 4-stroke single, albeit with a JAP 350cc engine. Saddle tanks and center-sprung girder front forks (state-of-the-art for the day, and Royal Enfield Motorcycles was one of the first to adopt it) were added in 1928.

WORLD WAR II BIKES
Despite all this, the company was in dire financial straights, but limping along. In 1931, one of the founders, Albert Eddie dies, then 2 years later, his parter RW Smith dies also. Times were tough, the Depression had set in, but Royal Enfield Motorcycles managed to keep it going. WWII hit at just the right time & again they were flooded with lucrative government contracts for gobs of military motorcycles, a collection that included a 250cc side-valve (SV), a 350cc SV, two 350cc OHVs, a 570cc SV & the most famous of them all, “The Flying Flea”. The Flea was a lightweight, rugged 125cc two-stroke that could be parachuted in with airborne troops. To avoid bombing, a brand new factory was built underground in Westwood, England, where it was found that the constant temperatures were ideal for making not only motorcycles, but “predictor” detonators for anti-aircraft artillery shells. Dangerous work, that.

BUILT IN INDIA
After the war, Royal Enfield Motorcycles resumed civilian production with the 350cc OHV Model G single & the 500cc OHV Model J single, both with rigid frames & telescopic forks. In 1948 they unveiled their ground-breaking new swing arm rear suspension, one of the first to do so. By the late 1950s, Royal Enfield was struggling again financially & so sold manufacturing rights & tooling to Madras Motors in India & production of 350cc Royal Enfield Bullets commenced in India, where it continues to this day.

TWINS FROM ENGLAND
But at this point, Royal Enfield was still building bikes themselves at their Bradford-on-Avon factory in England. In 1949, they joined the Vertical Twin Race with their own 500cc Royal Enfield Meteor. By 1953, they’d punched it out to 700cc (hoping to trump Triumph & BSA who only had 650s) for the Royal Enfield Super Meteor, then again in 1962 to 750cc in the Royal Enfield Interceptor. All the while, they built lots of 18hp 250cc OHV Royal Enfield Crusaders. They also dabbled in two-strokes, like the Villiers-engined 250 Turbo Twin. Nothing seemed to add up to the sales they needed to survive.

THE END DRAWS NEAR
By this time, the horsepower race was on, the Japanese were on their way and everyone was pumping up their bikes for more power. Royal Enfield followed suit with its Series I & Series II 750cc Interceptor, now good for a 13-sec quarter mile at 105 mph. The US loved the bike, but cash-strapped Royal Enfield was unable to produce them in large enough volumes quickly enough to meet the demand. That and a reputation for leaking oil (earning them the nickname “Royal Oilfield”) lead to their final slide into insolvency. By 1967, production has stopped and by 1970, the factory was closed for good, at which time Royal Enfield was acquired by Manganese Bronze Holdings and added to the scrap heap that would become Norton-Villiers (which would ultimately include Triumph, BSA, Norton, Matchless/AJS, James, Francis-Barnett, et al).

SOME INTERESTING TWISTS
Another sad story of a British Motorcycle Maker failing to embrace changing times. But there were some very interesting and unique aspects to the Royal Enfield Motorcycle story. First, that they are still being produced today in India as the fuel-injected, electric-start 500cc OHV single, the Royal Enfield Bullet. This new ‘Indian Enfield’ is built in a variety of styles, some mimicking military machines and Classic British Motorcycles.

How to adjust the valves on a royal enfield motorcycle

ABOVE: This 1956 Indian Trailblazer was actually a Royal Enfield Meteor-style 700cc twin, imported to the US by Indian and rebadged as an Indian Motorcycle. Note the Indian Head lighted mascot on the front fender. Even that couldn’t help sales though. It bombed.

INDIAN ENFIELDS & ENFIELD INDIANS
Another interesting twist is how Indian Motorcycles rebadged them as Indians and sold them in the US market. Interesting story. Indian had itself changed hands during WWII & after the war, the new owners wanted to get out of the heavy V-twin market and embrace the ‘new wave’ of bikes pouring in from Britain. They had tried unsuccessfully to lobby the US government to impose heavy tariffs and limits on British imports. When that failed, they decided that if you can’t beat ‘em, join ‘em. Indian squandered their dwindling resources on trying to build their own vertical twin on the British mold, but failed miserably. So, they became the exclusive US importers for Royal Enfield Motorcycles in 1953, which they promptly painted bright red and slapped Indian logos onto. And gave them very odd names like ‘Indian Chief’, ‘Tomohawk’ and ‘Hounds Fire Arrow’. Indian Motorcycles had thrown all its eggs into the Royal Enfield basket when it ended decades of production of its own V-twin. Unfortunately, the rebadged ‘Enfield Indians’ didn’t well well and so the marketing agreement was cancelled in 1960, at which point Royal Enfield Motorcycles became available in the US under their own name.

So, another oddity is that there are then “Indian Enfields” & “Enfield Indians”

3 CENTURIES OF BIKES
Lastly, Royal Enfield is the only motorcycle company still building bikes who can claim to have done so over a span of 3 centuries! Not even old-timers Triumph Motorcycles (1902) & Harley-Davidson (1903) can claim that!

Royal Enfield has revised the service interval and the oil change interval on its motorcycles with the unit construction engine, which will help reduce the cost of ownership by 40 per cent over three years.

By Sameer Contractor | Published: 10-Aug-19 03:50 PM IST

Having launched the new variants of the Bullet 350 recently at ₹ 1.12 lakh (ex-showroom), Royal Enfield has gone a step further and revised the service interval across its motorcycle range in a bid to reduce the cost of ownership. The bike maker has announced that it will commence the use of a new set of processes and technology, coupled with a new mix of semi-synthetic oil, for servicing. These initiatives will now increase the service interval on its motorcycles from the current three months/3000 km to six months/5000 km.

In addition, Royal Enfield has also increased the oil change interval to 12 months or 10,000 km, from the current six months or 5000 km. The move is aimed to bring down the overall service intervention required by a motorcycle in a year, thereby reducing the cost of ownership by about 40 per cent over a period of three years.

The new Royal Enfield Bullet 350 variants also fall under the new service interval

The new initiative though is limited to the newer unit construction engine motorcycles and not the older cast iron versions. This includes the Royal Enfield Bullet, Classic and the Thunderbird range, and does not extend to the Himalayan, Interceptor 650 and the Continental GT 650 motorcycles. The 650 Twins have a service interval of 12 months or 5000 km, whichever is earlier.

The reduction in the cost of ownership comes at a time when Royal Enfield’s sales are at its lowest in three years. The newly launched Bullet 350 variants make the brand more accessible to the masses in a bid to encourage potential owners amidst a struggling auto market.

2022 Royal Enfield Int 650 Twin: EASY COME. EASY GO.

Introducing the 2022 Royal Enfield Int 650 Twin…

2022 Royal Enfield Int 650 Twin marks the return of one of Royal Enfield’s most loved classic motorcycles. Hailing from a time when all that mattered was that the California sun was out and the surf was up, the new Interceptor retains every bit of charm that made it a legend. Here is the story of its revival.

Royal Enfield North America announces the launch of new colors for its 2022 650 Twin motorcycles—the INT 650 twin and the Continental GT 650 Twin. Both models also received a host of aesthetic upgrades, including blacked-out rims and fenders, and black fork gaiters, adding a stylish flare to Royal Enfield’s modern classics.

The 2022 Royal Enfield INT 650 Twin is now available in two new Standard (single-tone) colors—Canyon Red and Ventura Blue—and two new Custom (dual-tone) colors—Downtown Drag, Sunset Strip—along with a new updated version of the chrome variant, the Mark 2. The Mark 2 Chrome INT 650 is an ode to the original Interceptor 750, a throwback to the golden age of 1960’s California motorcycle culture. The INT 650 Twin retains the single-tone Orange Crush color and the timeless Baker Express dual-tone option that has been extremely popular.

Triumph valve adjustment
Q:
I ride a 1971 Triumph TR6 650. The manual says to set the valves cold, with the intake set at 0.002 inch and the exhaust at 0.004 inch. My question is, it’s hard reaching in to set the valves and I’ve always had a hard time getting those tight clearances right. I’ve always heard that valve clearances tighten up as an engine warms up, so I’ve been in the habit of setting them loose, with the intake at 0.008 and the exhaust at 0.010. A friend of mine says this is a bad idea, that I’m running the risk of burning the valves. It seems to run just fine, and I don’t notice that it’s any louder than other 650s I’ve heard running. So my question is, am I risking damage to my engine setting the valves this way? If there is a risk, what is it, or is this just an old wives’ tale? – George/Yellowknife, NT, Canada

A: I know exactly what you mean about the difficulty in reaching the valves on Triumph vertical twins. No, you don’t run the risk of burning valves by running loose valve tolerances. Loose tolerances actually allow the valve to stay seated longer, allowing more heat to transfer from the valve to the seat. What you do give up is flow and some high end power. That said, 0.008 and 0.010 is a little loose; too much clearance and you risk wear to the cam face, rocker arm and valve tip as these parts slam into each other at higher RPMs. I’d be more comfortable with 0.004 and 0.006.

How to adjust the valves on a royal enfield motorcycle

Royal Enfield motorcycles have a fan base in India and around the world. The manufacturer launched Interceptor 650 and Continental GT 650 motorcycles in the market few years ago. They are currently, India’s most affordable twin cylinder motorcycle one can buy in India and around the world. Just like Classic 350 and Bullet motorcycle, Interceptor and Continental GT 650 are also quite popular among buyers and we have seen several modified versions of these 650-twinz. Here we have a video shows an Interceptor 650 motorcycle that has been modified with S&S Camshaft.

The video has been uploaded by Abhinav Bhatt on his YouTube channel. The video starts with the vlogger showing a Royal Enfield Interceptor 650 that belongs to his friend. The bike looks stock at first but the owner has done several modifications to it. He starts with the rear suspension. The stock suspension on Interceptor 650 has been replaced with Paioli suspension. This is the same unit that we have seen on Continental GT 535 in the past.

As the setup on Interceptor 650 is different from the GT 535, he had to install the suspension upside down. The suspensions are adjustable and the owner says, it has improve the ride quality a lot. The next modification on this motorcycle is the set of slip exhausts. They are louder than the stock version but, not too loud to irritate others. The exhaust pipes used on this bike are from Power Rage and it comes with a DB killer also.

Other cosmetic changes on the bike include a new LED headlamp which is better than the stock halogen units. The turn indicators are replaced with units from Thunderbird and the tail light is from a Triumph Thruxton motorcycle. The main modification on this motorcycle however is the camshaft. The stock camshaft has been replaced for S&S units. As the camshaft has been upgraded, the air filter has also been modified.

How to adjust the valves on a royal enfield motorcycle

What Camshaft basically does is it opens the valves more and keeps them open for a longer period than the stock version. This lets more air and fuel come in and enhances the performance. To get maximum out of this system, he also has a piggyback that retunes the fuel and air ratio and enhances the performance.

The owner of this bike mentions that after all these modifications, it definitely feels different and has several. These modifications have affect the low-end torque slightly but, the overall performance is great. The vlogger who also has modified Interceptor 650 rode this bike and came to a conclusion that this motorcycle feels a lot more punchy and fun than the regular one or his motorcycle. He even tells that this motorcycle is a lot quicker than his bike. He even mentions that, it feels quicker than a Triumph Street Twin motorcycle.

The owner did not mention how much power has increased, he did mention that, he is waiting for couple of more things and once they arrive, he will take this bike to a Dyno test to know the exact figures. Interceptor 650 is powered by a 648-cc, twin cylinder engine that generates 47 Bhp and 52 Nm of peak torque in stock form. RE is working on several new motorcycles like a revised Classic 350, 650-cc cruiser and many more.
