CARBS AND GEARING

[oiledaplug]

Hi All,
Just got my third SF which is a 98 version R. My previous 2 were 1992 project big ones. Sprockets and chain needed replacing,so i bought a kit which had a 42 rear sprok. This made it struggle slightly on steep hills.Checking around i found it should have a 45 rear,which i have fitted and alls well. Question is, whats changed between the two models to need different gearing?
Second. how do i get to the inner two pilot screws to adjust mixture? Or is there a certain tool i can buy?

thanks chaps, JEZ

Hi, I was told that rear sprocket for mine (92 model, was 44, had a 45 on rear and 15 on front) wore out chain quicker...

Theres a an actual math to calculating thw sprocket size depending on what you want higher top end or acceleration and the type of driving you do mine is set up for the roads i drive on a daily

I'm running 16-39 gearing. Carbs are at 2 turns from seated on the mixtures. Does fail a little on steep hills but nothing a gear down or 2 can't fix. Makes twisties fun as don't really need to get out of first or 2nd (110 on limiter in 2nd.)
