Reply To: Begins to die at high rpm under load – GT250

Once I’m home from work tonight I’ll do said tests and report back.

Some other details about the bike might help. The bikes muffler has been messed with to make it louder and has very little in the way of restrictions, air filter is stock as far as I can tell, when I pulled the carbs to bits the most recent time I checked needle and slides. Needles were set to the third position (same as slide needle mod) and the slides did have some scoring, more so on one of them, can’t remember off top of head what side but will add photos when testing tonight.

I’ve set the slide needle back to stock to see if that changed anything however not alot happened. Main jets are the stock 90 and 92.5.

Also there is an extremely small oil leak in the front cylinder somewhere, not sure where the leak is coming from but after any ride, whether or not it’s a big ride or just a trip to the supermarket it will have about a drop of oil on a flat bit of casting (will add photos later) not sure if a gasket is unhappy or there’s a crack somewhere.

Thanks for the help
