With a cp 11:1 piston what the maximum i can shave out of the head to don't go past 11.5:1 and also without slamming the piston in the valves. Thank you!
Yes thank you for the advice/info. I guess I should do that upgrade now before it gives out on me.One thing you might want to look into is the timing chain it is a serious week spot on the 700xx motor. I raced with Matlock for a couple of years and his broke three times that I can think of. Alba racing sells a kit, but I am pretty sure its just the gears, chain, guides, and tensiener out of a 650r bike motor. You have to replace all the parts, but size difference is very noticeable, and worth doing.
Correct...and you do that by decking the cylinder not the head.The idea is to get more compression, about 11.5:1 with a cp 11:1 piston
A cylinder is allot cheaper than a head. You would always want as much meat on the head as possible, You could have head gasket troubles if you cut it down to much near water jackets etc.What is the difference?
Is your goal to get 11:5 or do you have a bad face on the head and in need of shaving it?With a cp 11:1 piston what the maximum i can shave out of the head to don't go past 11.5:1 and also without slamming the piston in the valves. Thank you!
My friend has a 12:1 in his 450r and seems to take well with 91octane? It is because it's smaller displacement?
