Bike has 35,000 on it. Bike sputters from 3500-4000 rpm's but then seems to smooth out after that. 70mph that I drive on my commute is right in this range. Carbs have been soaked, synced, and the diaphrams patched by my mechanic. He mentioned that it might need the needles replaced(He said it is not a fun or inexpensive job), or maybe new diaphrams.
Other than that bike runs great and gets 40-45 mpg.
Before I proceed I thought I would ask you guys.
Thanks
Doug
