Hey guys, I have a 1976 RD400, and I have a problem.
I'll be gunning it along, and always, when I hit 7000, the bike seems to choke up and splutter., and refuse to rev more.
Is it retarded timing or is it needing a carb readjust?
Or is there anything else that you would suggest is wrong with it?
Advice/knowledge is kindly accepted, haha.
