Yeah, JP is a big part of the reason I'm back on here.... and back to working on bikes. I got really burned out for a while and just kinda hibernated as a hermit for a whileIridiumRed!!! I'M GLAD YOUR ass is BACK. Good thing I called you 10x/day with texts for a month to get you out of your cryo state.
So you all have JP to thank, or maybe blame, for me being back. Hehe. Thanks for hangin in there bud
"1 Finn = 10 Russians".... yeah.... 10 PISSED OFF Russians... hahaha
But seriously, the more I've played around with engines, and talked to good and great engine builders, the more I've come to respect / appreciate how important the basics are to having a good running engine. Its easy to throw a set of "flashy" parts at a motor like cams, big bore kits, expensive exhausts, etc
It can be flashy because of bragging rights. Its easy to say "hey, I got this 1042, 1070, 1143 motor with big cams...." etc. hey, I do it myself!!
BUT ... all those parts mean nothing if the BASICS of the motor aren't cared for. And setup properly - with the right clearances.
Things like ring seal / having low leakdown numbers. Pulling a ton of air & fuel into a cylinder is pointless if most of it slips by the rings.
Things like having GOOD valve jobs - like .001" or less runout on the seat, with a good seal with the valve seat. And valves / valve guides with a tight fit, so the valve doesn't wobble / leak / beat itself up... or leak oil into the combustion chamber. Not too tight though, don't want anything to seize.
And having good valve springs - enough pressure on seat & open to keep valves floating, and plenty of extra room so they don't bind. But not so much pressure they wipe out the cam lobes / valve lifters.... etc etc etc
And having enough compression to build power, but not so much it detonates. Is WAY better to be down a half point in compression than to have a half point too much that it detonates.... next to oil starvation, nothing will kill a motor faster than detonation....
Anyways! good luck with your build. Keep us posted
PS. Oh yeah, one last basic thing about building engines I've learned - clean clean clean ! And clean it some more! Just don't fuck up the surfaces while you clean
