cheers. found a similar chart on a Honda forum yesterday, if anyone's interested here it is http://honda-tech.com/showthread.php?t=3063102 bit of a topic change but can anyone tell me the minimum piston to valve clearance?

cheers all. @ ReVhEaD can't do pictures, phones not compatible with site and can't workout how to cut and past on computer. its fluffy black on threads and ring. Electrode, tip and porcelain clean, like new. did take it for a squirt before I pulled them, kept it above 3k apart from when I backed it into shed. Did a comp test, lower then I expected . 9.8, going to a solid cam so need to up it to 11. thinking I'm gunna offset grind a crank and have the ring/lip on top off the pistons milled down to bump comp depending also on deck hight. Already talked to the guy I get my machining done ,said he can do it with the conrod on. Ando, that's not weird, This is weird. http://m.youtube.com/watch?feature=youtube_gdata_player&v=FbuluDBHpfQ&desktop_uri=%2Fwatch%3Fv%3DFbuluDBHpfQ%26feature%3Dyoutube_gdata_player

lean?

I rebuilt my 250 in my pre internet days and wasn't aware of the issue with fitting a high volume pump to a xflow so I fitted one. cold 50psi. worm 25psi. at about 800/900 rpm. think its got 15/40 in it atm. last build was about 3 or 4 years ago now. don't do many ks in it. when I pull it down to increase HP will probably go back to standard.

ooooo I'll message you.

cheers... two. info i need to order valves to suit 647 cam ^^^

something I'd like to know as well. Was gunna do it myself when I get around to it, and probably still will, good to have a comparison when I do. I'm mainly interested in length and diameter.

also why would it not be a good idea?

while we're on the subject what would be the bonuses of swapping from a 3 speed to a 2 speed. when would it be a good idea and is top gear ratio 1 to 1 ??
