Dragging a 350

Anybody into dragracing out here, do drop me a line. have a modded yamaha RD which we been trying to race. the bikes capable of doing low 12s i guess but we are facing a lot of mechanical issues with the bike. especially the gearbox. damn thing takes off at launch, only to hit a stubborn 1-2 shift. the 2-3 shift is better, but not by much. rest is cool.

right now the config is something like -

drag porting - nothing heavily fancy but, widened and raised exhaust and transfers

racing CDI - running a digital CDI from www.rddreams.com. has a varible curve, down side is that it needs a batt. but whole thing works like a charm

carbs - 34mm mikuni roundslides, bored out to 35mms. and with powerjets, size 80 swingarm - extended by 4''

pipes - pipes from stannakjak.com, skalman racing

sprocketing - bit of experimentaiton going on now, 14/42. yes its wierd i know. modded gearbox - with the dogs cut for better high-rpm shifts. no angle cuts though.

right now the whole thing is setup for high 12s @ 100+mph. software predictons show 55bhp@10500 rpm. powerband from 8k to 11.5k rpm.

if somebody out here can help, some questions -

o will stiffer springs on the clutch plates affect gear shifting?
o will sprocketing affect gear shifting?
