Rode it 24 miles yesterday to the shop. Ran perfect for some bits of the road then would start to load up and break up. Just cruising or under load didn't seem to matter. Stopped in traffic had a few small airbox pops and one big pop from the left pipe on initial acceleration.
I can't imagine how it can run at 70MPH perfectly, then not, then perfect again. I hope he calls me up and says, "Hey, its a little hole in a hose". I don't think so. I fear hes going to call me up and say its coils.
