Question about 1982 Yamaha XS 400 Special
Require to have full choke, and takes approx 15 minutes to warm up. my left pipe is hot during this and my right pipe is cold. do i have a stuck exhaust valve? i also noticed my plug is black, still charging a spark, but a power loss is highly noticeable.
Hi the xs400 was known for carb problems the diophrams in the top of the carbs look for holes in them
