TEC Performance Cam Camshaft Royal Enfield Himalayan / SCRAM 411 HM410 all years

Description: TEC Performance Cam Camshaft Royal Enfield Himalayan / SCRAM 411 HM410 all years TEC Description:Some other makes of camshafts are now available for the 411 Scam and Himalayan, BUT we have noticed that these do not have all of the pressure oilways drilled to the bearings. This is done to save money and looks like they are relying on oil splash to lubricate the the camshaft. This is not a good idea when the cam runs directly in the head and any wear would require a new head assembly. Elsewhere you will find that competitors have just ground the base circle on the stock Himalayan / Scram 411 camshaft. However, we found that this restricted the way the timing and lift could be changed. Lift on a re-ground stock cam is also restricted by the tappet adjustment range to about 0.5 Millimetre in lift. Modifying a stock cam also means the exhaust valve lifter arm needs to be ground very thin. So, you can see why we started with a fresh blank steel billet and developed this drop-in Stage 2 fast road tune Camshaft, to give more lift ,duration and valve overlap . This also means the problematic exhaust valve lifter mechanism is no longer needed due to the Camshaft timing and valve overlap. Made in the UK from scratch with a single piece of machined billet steel before being heat treated for hardness.Tested extensively on all Euro 4 and 5 models during summer and winter temperatures. Easily fitted by amateur mechanics (see our detailed video below) and even without any other changes to the ECU this will give around 20% extra power. Detailed written instructions with diagrams included with the part. Please see the Dyno sheets on our 2019 stock Euro 4 Himalayan with standard ECU, more power can be gained with other simple changes if you wanted to go further. The 3 Dyno runs are:1) Bottom line – stock Euro 4 Himalayan 2) Centre line – Same bike with just the new camshaft installed, no other changes3) Top line – Same bike with camshaft and DNA air filter and free flow silencer installed One big advantage is that the bike now has the power to pull an extra tooth on the front sprocket which gives higher cruising speeds at lower revs with the added bonus of improved MPG. This camshaft will completely transform your bike! Keeps all the bottom end torque, but gives much more urge above 4000 RPM ( see graph).Runs smoother with no more struggling to over-take 56 MPH lorries!
