i've had the bike for 2 years and i have never been able to rev past 7000 rpm in top gear, the engine starts cutting out. the exhaust system is a four into one black coloured unit with a black muffler attached. i installed pods on the carbs hoping this would help with the rich fuel mixture, but it did not.
i adjusted the valve clearance 4000 km ago and this helped alot with cold starting but not the fuel mixture.
is there a "ggod guess" as to what size main jets to install on this bike when i'm rebuilding the carbs?
i noticed at one supplier on the web includes main jets (i think) with the rebuild kit for sale there, is it possible these jets will work ok?
18 years ago i had a 1975 honda 750 (i'm pretty sure it was a 75) and i purchased a 4 into 1 chrome pipe for it (hooker i think), i popped the exhaust pipe onto the honda and it worked (and sounded) great, no need for jet adjustments etc.
is it possible to do this with a suzuki gs 750? if the jets that are in the bike now are too large, should going back to stock make the bike burn it's fuel properly and hopefully rev higher under load?
one more question, what do the screws that are painted yellow under the carbs do and can they be adjusted?
thks
