I have a set of Graham File tuned crankcases which I would like to use with my standard KR1 cylinders which therefore requires a total engine strip down and rebuild. Would it be ok to join the cases with Wellseal, or do I HAVE to use Yamabond or H0nda bond for this type of job?

used Ducati sealer on mine its grey so does not show so much on the joints and only costs about £8 p&h motorcycles stock it if its local to u

I use silicon sealant from Kent (black) or Loctite (blue)

I use Wellseal on mine without any problems what so ever. Just give it plenty of time to go off before joining them together.

I used Threebond on mine which is recommended by KTM. Yamabond is really good too. Used to work at a Yamaha/Kawasaki dealership.

I use Yamabond (grey stuff) for the cases and h***a (black stuff) for the heads.

I use VHT Copper coat for the head gasket. Have used the same head gasket over and over again, just spray the stuff on, no leaks. What's the h***a stuff you use?
