[QUOTE="TWS, post: 37714, member: 37"] You will gain low end torque and if yor lucky no more than a couple of ponies. One thing to be aware of if your raising the compression and bore on a tired old crank and rod you might be asking for trouble. Another thing on a BB kit you can over do it by using to high of compression on the piston. I don't know what compression your at now or alot about a smoker but 14.8 seems like alot. 2 strokes all ready have a pre detonation issue. I would be ready to use race gas or higher octane fuel than normal pump gas. Be ready to go through some jetting blues.:smirk: [/QUOTE]
