I just rode again and everytime i would come to a stop after i rode 20 mins it would die on me i would sit for a few then it would fire right up what is going on?? Do u think it maybe the 2 cycle oil im using it only dies when stopping when i ride for 15 or 20 mins and still there is no gas in the recoil area.

 

Do a compression test like I mentioned earlier. OPT

 

I haven't done compression test yet been tryn to borrow one off somebody haven't had no luck though, do u think it needs rebuilt? It was firing right up after I rebuilt card now it won't fire up at all

 

Pull the spark plug,plug it back in the cap and ground to the engine to see if you still have spark. If you do have spark,then borrow the compression tester. This will tell a lot, whether it might need a new top end or not.OLD rule of thumb was the thumb pop test,but not always accurate. Place your thumb tightly over plug hole and have some pull the recoil starter. If compression blows your thumb up,usually compression is adequate.But again this is just a rule of "thumb" Beg,borrow,or steal a compression tester and post the results! OPT

 

It has good spark jus did what u said

 

Did the thumb test and it blew my thumb off we did that numerous times jus now

 

It jus fired up I'm not sure what the problem is its like its over heating I'm hoping to get a compression tester soon

 

Now check compression the right way with the tester! If it continues to die on you after about 20 minutes or so and you have to wait for it to cool down to restart,then still sounds like top end work needed or the crank seals or both. Accurate compression reading will tell where you need to go next. Post back with the readings. OPT

 

Ok I will post as soon as I do the compression test does the top end rebuild mean new piston and gaskets?

 

im going to replace my piston and im looking at kits on ebay my question is what is the stock piston size for a 1997 trail boss 250? On the top of the piston says 5W if that means anything? thanks
