Harry no offense here. But does anybody else think it's funny when Group K Harry Klemm posts and it says "Newbie" under his company. Rich
View ArticleRe: GroupK 1350
Yeah, I think it's pretty funny, and even more IRONIC, since Harry Klemm is one of the best jet ski minds and outfits in the industry, and to have him post for all of us to see is a blessing! Newbie...

Actually mine are 46. The difference betwen the 44 and 46 is acceleration and about 20 RPM on top in my case. The larger piston bore IMO will benefit from a larger bore carb. I think that a set of 44...
