Jb Power, Comp. ratio 12:1, 99mm piston, 1016cc...

It's the first time that i hear about a big-bore kit (other the 1200cc of the German Factory...)

An awful lot of money for a very slight increase in displacement (in my opinion). For that price, you can get a set of custom 0.5mm oversize (allowing you to use OEM Honda rings) JE (or CP) pistons made (to your specs). You need to order a minimum batch of 4 (with JE anyhow) but can sell off the other two. That will get you up to 1006 cc for a whole bunch less money (btw, this is precisely what I did, along with another forum member)

Of course, if you don't want the hassle and can afford it, it is likely a decent product. I have bought from Webike a few months back and received excellent service FWIW

Yes Mikstr, i also know the 0,5 oversized piston...

But is interesting that you can increase the capacity....

for the JE / CP piston at measure, it would be interesting whit 100 or 102mm.... that would mean 1036 or 1078cc..........

but "how much" is possible the cylinder bore? And next, for the nickel?

I think it's a very interesting way for gain many cv....

another question.... have you bored your cylinders for going to 98,5mm?!?

yes, of course
