well jay,theres a lot id like to be doing for the winter and maybe you can help me out.i posted earlier on today and got replies from pitter B4 and racerruss,thanks lads!ive a 95 B4 and wondering is it the gk73a (i ordered some before and the breaker asked is it the one with single or twin exhausts) model i should swap the cams from,are the gear ratios on the gsxr400 the same as on the B4,should i stick on gsxr carbs,me B4 tops out at 112 m.p.h.(going by the clock pitterB4) is it simply the carbs that cause this? And lastly ill be fitting a buell blast screen i purchased while visiting 'Iron Valley Motorcycles' in lancaster PA in september,took 2 months to get here but for ~$70 as cheap and cheery as chips! thanks lads!
