DIY Work

  • Oil change
  • Left crankcase gasket replacement
  • Seat cowl and main seat replacement, seat band transplant
  • Headlight rim replacement

There had been oil seepage from the crankcase since I bought the bike, so I knew the gasket needed to be replaced. I successfully cleaned up the mating surfaces and put in the new gasket, but when I went to reassemble, I put a bolt in the wrong hole and stripped the threads.
The crankcase bolts come in two lengths, and I hadn’t kept track of which hole took which bolt.
This ended up costing me quite a bit to repair.
I suppose I should be grateful it was even fixable. (Worst case, there was a risk of cracking the case.)
