Hi all,
Maybe this is linked more to carb section but I have replaced my rotten OEM exhaust with Delkevic downpipes+collector and BSM cans. Combination is not the best match for the ST because downpipes wont fit very well, they need serious force when installed and those cans have too much flow, I guess. OEM silencers have an about 28mm hole in the end but these absorption-type cans have 48mm straight pipe through the whole can. My bike is quite noisy and it accelerates a bit slower in low RPM (1000 to 2500-3000) than a bike with OEM exhaust. It is a bit tractor-like, noise gets louder when I turn the throttle but acceleration is bumpy till 2500-3000 rpm, not smooth increase of speed like it usually is with ST's.
My plan is to take the bike to specified exhaust shop, I'm sick and tired in badly fitting aftermarket parts but has anyone made experiments with bigger jets etc in situation like this? Or has anyone ever faced similar problems with aftermarket cans and/or downpipes?
One fast solution is some kind of noise killers, too.
