compression release on my trimoto200

[Choppers4Life]

will my tri moto start with the compression release stuck open, im askin if it will run long enough for me to manually un-release it....my cable broke... and im wondering if it can be rigged or not

Nope. Get a decompression lever off a YTM225 and get rid of the cable.

You can flip the decompression lever up to start it. Once the motor turns over so far it should automatically release. This is just how they work. I did it this way on the Yam 200 I had ( it was stolen ). Never had a problem.

There usually isn't a cable... It's just a lever that has a spring on it. When the valve is pushed down by the rocker, the lever comes down, since there is nothing holding it up.

Yamaha put a cable on the 200 chain drive model because it is the only one without electric start. Yours can be used manualy it just doesn't have a tab and nice little rubber cover like the other ones that don't have a cable do.

Would a compression release issue cause back popping into the carb while its running? The timing is perfect, has new piston and rings but it backfires into the carb

No. The decompression lever only controls the exhaust valve. Popping in the intake is usually related to a timing issue (cam or ignition) a lean condition or possibly an overly tight or leaking intake valve.

If the problem seems to be worse when the engine is hot then I would be looking at the valve lash on your intake valve as it might be too tight.

Next thing is to check for air leaks around the intake manifold and possibly a plugged pilot jet that’s giving you a lean condition.
