Question

I have a 1988 Yamaha Moto 4, every time I shut it off it backfires. Can anyone help me with this?

Answer 1

Does this always happen after "Racing" your "Motorcycle".

Answer 2

change your plugs and decarbon the head

Answer 3

Sounds like your timing is a little retarded, try advancing the timing and see what it does.  Although this is not a major problem it has been known that backfiring can destroy the exhaust system.

Answer 4

all its doing is backfiring? this is something that needs no special attention. Its not a bad thing, but this question would be better answered if it were asked in the motorcycle forum, and not hte motorcycle racing forum.....

Answer 5

Check ignition timing
