ok so I took my top end apart because my friends uncle wanted to port my cylinders for me, he used to race the RZ's and also build them so he loves these engines.. anyways. It ran good before, and wasnt the highest on compression, but already had the cooled head, 22cc domes, full fmf's uni filter with the lid on, and I'm at sea level. So I got the cylinders bored its a 358cc now, all new gaskets, seals, reeds (boyseen super stock) and its ported. while it was apart I also painted the frame metallic gray as seen in my photo. I got it back together, it runs and idles but wont rev up, I can put it in gear, let the clutch out but cant gain speed and in neutral it does the same. It will idle good, but when i get about 500rpm off idle it just boggs right down.. not sure if its the porting or the good compression or what.. but my mains are at 260 which seems low right? not sure if this is maybe the problem? ive tried so many things, making sure all the paint is ground off where the wires bolt to the frame, new plugs twice, new plug caps, ive replaced the reed gaskets twice, Ive tested my tors I unpluged it, still did it.. I moved my clips down all the way to the 5th (towards the point) of the needle, still does it, when its doing this bogging it doesnt rev at all, its staying at a constant rev, almost sounds like a very low rev limiter, around 1500-2000 rpm.. Not sure though... the only other thing I can think of is my mains, I'm waiting untill tuesday now Im going to get some 300-340s I think.. let me know guys, I really want to get this thing back on the dirt!
