Just got my first ever 4-stoke 11-05-04. Love it. I have always been a die heart 250 2 stroke man. So I know nothing about 4-stokes. If anyone knows any problems areas to keep a eye on please I need to know . I'm also looking for the best bars to buy for vibration. The vibration is not bad but I like the 1-1/8 bars & need some input on the the best one to keep the vibe down.
