Well, after the news of a decent tax return coming my way, I am thinking of getting some porting done. My banshee is now 5 yrs old. However, I wouldn't consider it to have alot of hours on it. I have to trailer to ride and I maybe get out a dozen times riding a year I would guess on average if that. My compression is still very solid on both cylinders. The thought of puttng in a new top end might stop me from the idea because of the extra cost. I guess my question would be is it worth getting porting without doing a new topend at this point? Also, I am not about to split my cases to get the crank welded. I don't have the experience to go that far yet. Give me some thoughts.
