My friends blaster has just recently not been running right.. He has a pipe k&n air filter and has been running it with the stock jets and needle. He has been riding it like this for about a month now and it has been running fine but now when he starts it up it will idle fine but the slitest amount of gas you give it will kill it instantly. We've changed the jets a bunch of times and cleaned out everything.. i am just not sure anymore.. thanks for any help alex..

 

take off the tors

 

Im not too sure what the tors is can you explain and today I even called the cycle shop downtown and the service worker there said because i have a pipe and airfilter all i have too do is change the jet and the needle and i did and im still having the same problems of bogging down as soon as you give it gas and fowls plugs quick... are sure what else it could be its getting good compression and Ive must of gone through the carb about 8 times. I thought it was watery gas and even changed that but the same problems. Do you have any ideas... im getting ready just to take it to a shop even though its a waste of money, I just cant figure it out.

 

You may do a leakdown test. Maybe the crankseal is bad on the clutch side. This would let tranny oil in which would cause a bog and fouling plugs.Here is a link to common problems with blasters and fixes. It also has a write up about the TORS system that JLSparky talked about. But I don't think that is the problem
