Hey guys, you helped me once and need your help agian. No one can tell me if my current setup is adequate enough for the r629 kit, instead of the r619? I'd go with the r619 but they aren't gonna have any made in 6 weeks, and I'm not willing to wait that long. The r629 kits are in stock though.. same price too. Powersports dealer told me he'd go with the r629 since it's bigger and couldn't think of how it'd be different from the r619. I mean yes, it's higher compression ratio, but I'm not certain how that gets taken into the whole equation of the engine.
My current setup is stock FZR600 carbs, stock FZR600 engine 'cept for the soon to be overbore, all in a fzr400 frame.
Also, I have yzf carbs that I've been wanting to use but someone said that they lost a little lower end and gained only a little higher end. Will these yzf600 carbs work better on the overbored engine? or should I still stick with fzr600 carbs?
Sorry for long questions, but no one seems to beable to tell me why or whynot I should go with the 629.
