Good day Ghost Rider.
This is just my 2 cents, based on my own bike's mods. I think there are 2 things, that are the gasket and the compression assemblies(which is used to make it easier to start the engine). For my current mods, I had removed the assy, and use custom made gasket(made from soft-drink tin can cut into the gasket shape =P). The stroke were somewhat become shorter I think, but the compression is significantly increased. Also, the head of my piston is etched matching with the four valves shape to prevent it from knocking with the valves. Also, the valves chamber had been rebored, to make it somewhat larger. The result, make bike become extremely light! My bike had really great acceleration! See my full mods on the left side for details. I'm using a very thin EO too. The problem now lies with my 4th gear. My 1st gear till 80km/h, 2nd gear till 120km/h, 3rd gear till 140km/h, 4rd gear still only 145km/h something only T_T sad sad. Maybe its due too my aftermarket camshaft, which I'm not really sure what kind and what profile.
Hope that's help.

Cheers!

just as sir traxx said that the YZFR125 and the FZ150 have the same chassis and engine, is it possible to replace the FZ150 fairings with the R125?
because here in the philippines, we only have FZ150, maybe the body kit of the R125 fits on the FZ150 (just like x1r and sniper)
any ideas about this?
