Hi,
I've found this site and you all to be a wealth of knowledge in preparing this build.
Started as an 81 Yamaha XS400 Special?
This is its current state:
Got it running pretty good with the Mike's SX Carburetors and stock exhaust.
I've installed new spark plugs and confirmed correct ignition timing with a light.
Quick questions:
What would make the idle hang up high after revving, and at the same time it's popping and backfiring in occasion??
My initial thought is that it's too lean..
I haven't adjusted the valves yet.
Any suggestions are greatly appreciated.
Thanks!
Andy
