heres a couple of pics of the finished job:
heres what ive done to the engine so far:
61X cylinder 771cc resleeved with NW bigbore sleeve, ports are matched & polished
set of 85mm Pro-X pistons
61X crankcase heavily ported and clearanced for the BB sleeves
custom made girdled head with ADA 38cc domes (175psi)
R&D 61x twin carbs intake
2x 48mm Dan Lamey Mega Flow carburetors (mikuni)
Riva F/A
everything else is stock
still got a lot of tuning to do, power is very lacking when i slam the throttle off idle, not snappy at all. also lacking a bit of bottom end. midrange is absolutely crazy tho!! :biggthumpup: havent check yet hows the power on top end. i was wondering also if the off idle response is related only to the engine or it can be the jet pump? i got massive midrange but its not ripping at all on the bottom. anyway, tommorow, itll be the first time i will try it with 2x 48mm. since they were originally from a 783cc stroker and are jetted to be used as twin (17psi popoff, 120L and 150H), im pretty sure it will run a lot better than only using one.
