- I fitted a replacement set of cams to the R.E. 350 racer and needed to make a few checks before I could start the engine.
I hope this might make sense, but there can be easier ways, especially with engines like these, of checking and making sure the valves and pistons have adequate room between each other without removing the cylinder head and using Plasticine between piston crown and valves as a gauge to make sure. In this video, I was fitting some very similar, but not identical cams to some which had become worn and damaged. When an engine like this is tuned to exceed 9,000 RPM, there is no way you want the valves getting too close to the piston and this is how I make sure they will not do so. I can also make sure the valves themselves have a bit of extra travel available after full lift and are not making their springs go coilbound and also that the valve spring caps are well enough clear from bottoming out on the tops of the valve guides, which would also cause damage.
Finally I was ready to start the engine, but I was on my own and had to push the bike, which started on the first attempt since 2019, so I could only whip the camera out from my pocket and start recording once the engine was running, but we have a runner once again.
Wow an Enfield, albeit somewhat special, is faster than a 7R AJS. I'd have lost that bet. Nice. Very nice.
Wish my wife would start and warm up as quick mind you next doors wife warms up well , good job paul
I'm impressed with your out of the box thinking, nice job and informative as usual. Thank you.
That engine sounds absolutely so well put together..... crisper than crisp, another Henshaws classic crisps selection 👌
saw the vid of that running, sounds a very sharp little motor
Great job as always! Thanks!
There was a more in depth description of this bike that Paul uploaded some time ago for those interested. Search for:The Performance Classics Royal Enfield Clipper Racer.
Thanks for that!

Clever ! well done mate what a sweet engine .
Had a Royal Enfield 500cc silver bullet back in the day never could get it timed correct many tried and failed.
That sounds like a ripper!!
One thing to consider, not all rockers are equal.
You may have a cam that gives say 600" lift but at the valve the lift may be greater or less!?
That 1" travel clock you now have can verify exactly what lift you are getting.
Hi Hugh, most rockers I have encountered give between 1:1 and 1.5:1 ratios and in the case of this engine, we are near, or at, 1:1, so I know my 'over adjustment' at the pushrods will give me at least that amount at the valves.
Owwwwwwwww a push rod beat a 7R - amazing
👍🏴
I believe the 7R was about 40hp or therabouts. Do you know roughly what your 350 is putting out at the crank. Fantastic getting that track record. And the bike sounds great.
Thanks! I have dyno footage on CZcams and this engine gives 35 BHP @ rear wheel and is clear of 30 BHP for a rev band of nearly 3,000.
Sir, what's the Max hp & torque?
I would have to look at a dyno graph to check the torque, but it is clear of 30 bhp from 6,000 to 9,000 rpm, with 35 bhp max @ rear wheel. There are videos of this machine on the dyno, just look for Royal Enfield 350 racer on dyno.
Here is some footage:

Paul what's all these millimeter things?
It is the things that makes us that not live on the iland understand 😂
