How badly does the throttle stay open ?
Do you have a friend that can maybe help look at it ?
If it's really stuck open would not be safe to ride it like that.
Like the throttle legit just sits at the one spot where ever i place it and it does it snap back at all. The revs continue to increase aswell lol. And i know it couldnt have done anything to it as i have never raced it i just left it in my garage one night came back the next morning to this because it was working perfectly the day before. Maybe the previous owner did not winterize it properly which cudda caused the lube or oil to dry up. I honestly dont know haha
