Listening to you problems makes me not want to do it. Sounds like the same problems i have been having with my 2 stroke MOD. Is this a issue that alot of people have.
There was too much heat in the engine compartment and that was it. Re routing fuel lines and/or proper venting solved the problem. If this problem scares you away from a TNytro you gonna be missing out my friend. There just aren't a lot of issues with these sleds regardless of who's turbo kit is on them.
