One of the best quotes I ever read on the advent of HP...
If you can leave two black stripes from the exit of one corner to the braking zone of the next, you might have enough horsepower.

thanks Brooking, at the moment I wish to do all the works step by step, I will come back to you when the engine is ready to runHi again Yves, with the Driven (Joe Gibbs)break in oil you have quite a few options with this oil.
How I do mine is making sure the ignition timing is correct on the first start up.
Then I take it to a remote area of country roading on tarseal (10 mins here in NZ) and run the bike up and down hills (not steep) not exceeding 3800 RPM and putting some load on the motor in this rev range.
I do this for about 30 km's.
Then I do a retorque on the head bolts when cold, then run the bike again over 30 km on the same piece of roading and up to 5500 rpm, making sure I load the motor (dont let it labour)
I also check the magnetic sump plug for any material.
After that process I drain the break in oil ,install a new filter element, one more head retorque add new normal running oil and go racing.
You can also do a few dyno pulls on that break in oil and as much as one round of racing if required before you change it for the normal running oil.
Great results with my motor so far.
Regards Mike
Thanks Pierre, very usefull information
It is possible that the bushing was a bit on the tight side when it was originally assembled, then "ran in" to its current clearance. The ridge is, most likely, what the bushing was originally sized to, so the cam feels tight when moving it into that position. You did just fine by filing it away. It's obvious by the fact that there's a ridge left there that the cam never ran in that spot, so you haven't removed anything of consequence. Rock on!But the question is: wats make a ridge?
Hi Nigel,Sounds great Yves.
Looking forward to the next instalments !!
Hi Nigel,So... you got the cam on Monday and it’s still not running...?
Disappointing...!
