So, I picked up a '96 WB1 last year. The specs are:
62T/61X motor w/stock 38mm carbs & aftermarket F/As
Factory pipe w/mod chamber
Blowsion one piece girdled head w/33cc domes (makes about 155psi @ 5,000' above sea level, where I ride)
Stock pump and impeller
Jet Dynamics extended ride plate
Pro-Tec top loader intake grate
I took it out to the lake, and it ran good as far as not missing or bogging or anything. But it did not have the bottom end acceleration I expected. Also, when I got on the top end, it porposed badly. I tried shifting my weight as far forward as possible, but could not get it to stop. I think because of the porposing, it was hitting the rev limiter also.
I already picked up another ride plate, a 13-17 concord impeller, and I have a modded CDI w/ adjustable rev limiter.
My question is, what is my best options to get better bottom end acceleration? I could get a limited chamber, or I could get the cylinder ported and use more of the mod chambers capability.
