I have a 2007 cbf 250. I rode a vt750 the other day and as soon as i got back on my cbf i noticed a massive difference. MY clutch lever is very heavy and also rather spongy. Does something need some maintenance or is just because its a crappy cheap bike? Also compared to the cbf125's i rode my bike cant idle for shit. When first started Sometimes itll stall even with full choke. The 125's idled instantly with no choke. Is there anything i can do about this? thanks.
