Hey I need some help this morning. My 450 will start and run for a little while before it pops alot on decel and dies. Once it dies I normally cant get it started again (I put a hole in my shoe trying to kick it so many times). I have had a problem with it running rich, and was going to try to work on that problem (I have had the bike apart all summer, and have done lots of maintinance to it), but now it seems much worse. Is this a carb problem? I do not know what jets the previous owner has in it, but today Im thinking about pulling the carb and replacing the jets with whatever my local yamaha dealer recomends I put in there. Another posibility is old gas, I have almost always been good about putting fuel stabilizer in my gas if I wont be burning it in the next month, but I am just not sure if I added it to the gas that sat in the bike. Im going to get fresh gas in the next 30 mins, so hopefully this will help. Any thing to look into/advice? Also are jets and a carb rebuild kit (gaskets etc) normally in stock at most dealerships?
