Motor Boring

[jonnyrebel2004]

I have a 2000 Banshee that I am going to have Eric Gorr do a woods port on. It also has a Noss cool head with 20cc domes and an FMF exhaust system. I am thinking about also having it bored .030 over since I am rebuilding the motor anyway. What I wondering is how many cc would I gain?

You won't gain enough to notice. Save those bores for when you need them otherwise you will be resleeving in no time.

It would make about 355 cc's

I thought boring wasn't very good for power. My husband was telling me that you have to build a stroker to do any good.

I have two bikes that are bored .080 over and I can only notice a real slight difference on them compared to stock bore. They are bored due to age and use though. 370cc vs 349cc not much diff in performance. After you start adding some other stuff on like pipes, porting, timing, flywheel, reeds, heads, carbs it will be a little bit more noticeable, but still not worth the loss of a couple re-builds.
