I have a Weakends pipe that looks like this:
Of course there are no rivets or screws to get to the baffle, I'll have to cut the thing open. Before I slice it open and have to find someone to reweld it, how many miles do you normally get on the pipe before it needs a good cleanout and repack?
I've had a ridiculous time trying to jet and get a bike running without blowing the temps up, so after checking for all the normal suspects, I'm down to maybe a pipe blockage or the crank seals.
So, mileage before cleanout?
