Default gst 7.7 exhust question

hello what is the best way to get the rubber gaset that goes around the engine that connects to the exhaust pipe on with a solid fit? i think i am having some issues with it running hot and shutting down i think it has to do with that. the gaset and muffler is not flush to the engine. every time i try and put the pipe over the gaset it bends up and doesnt' let me get a flush fit.

When I had my GST i had the exact same problem as you. I took some CA glue and put it on the inside of the gasket. Let it sit and put soap on the header. It slid on easily.

hello i bought the crazy glue today and took off the ehaust and cleaned it up put some crazy glue around the trim of the new gasket and let it dry for about and hour or so and put on the exhust and it feels like it is more firm when i was sliding it back on which i hope is good. i will try and light it up this weekend and hopefully i got rid of my mid riding shutting down problems.

If you are having half tank lean issues this will not solve that problem. That is a whole different animal. Have you done the Checkvalve mod??

i have the checkvalve mod installed. its not really a half tank lean issue. last year in the summer i took it to the park ran it for like a few mins and mid to high speeds and it just shut down and didnt' start up again. this is the main problem with it. the engine was running hot so i was thinking it would be an exhust issue cause i think i tuned her right.

have you checked the temp when I shut own?? If it gets hot at that speed the there could a few thins happening and if the gasket is torn or damage or not even seated properly, fix that first the try again
