I just finally registered on here and had a few questions about the b2. I just bought an 86 k5 two weeks ago planning a full rebuild top to bottom. I bought the bike not running. It had only 90 psi compression and barely any spark. Plus I noticed the dry seal was blown, filling the stator cover with fuel...lots of it. So I tore the engine apart inspecting everything. replaced all seals, and main bearings.
Cylinder is stock bore, thoughts on nikasel?? or sleeve??
Now, Ive been following your threads on exhaust. Should I grab a full 89-04 fmf pipe and silencer? or go pro circuit?
Piston- I have a new 86 stock one, single ring, flat top.
Will an 89-04 work. It has dual rings and a slight dome top. will it have to be machined to prevent squish band damage??
Intake- I need to buy a new manifold, i have the stock rubber one, but wanted your thoughts on
v-force reed valve,.....or just use the stock cage with updated reeds and spacer kit?
Clutch- would a 89-04 clutch kit fit? b2 only uses 5 springs. so does the newer kits come with 6 springs. Do I need to buy a 86 specific kit? Barnett makes a kevlar kit for 150, should I run aft type f......or 30 weight oil? thoughts??
Lastly, any sweet mods that are easy and cost effective to boost performance?? Like drilling air box cover/ new air filter. Reeds/spacer. Exhaust/pipe.
thanks bro!
