I recently got my motorcycle checked by a mechanic. Its a pretty old one, 87 with 18k miles. There was a problem with the vacuum seal next to the head gasket, got that fixed. oil changed and basically given a complete lookover.
Got her back and it was running smoother that ever before. However a couple of days back it would not start. The gas is full, the battery is charged.
The guys after servicing did say that there are some petcock issues and it supposedly always runs on prime. I am not very sure if I believe that though, because I nearly ran out of gas and the bike would not run in On but was smooth on RESERVE.
So anyways anything that I should be worried about, talk to when I take it back. I really dont want to mess with it myself right now as I paid quiet a bit of money for the servicing.
