I rebuilt my engine with new seals when i changed the crank, so they should all be good. I'm most bothered about leaks around the inlet and that carb 'boot' thing after Matt did that post about over torqued ones.

Has anyone here got a motion pro 2 stroke leak down tester??
I'm frightened of starting my expensive, 300cc ultimate motor of doom without being certain that its sealing properly!! (had lots of problems with my MZ racer in this area) Making my own tester would be a fat load of hassle that i can't be arsed with so it would be cool if someone knew if the motion pro kit works with the NSR engine or not.

Thanks Laurent, but with one piston at BDC, does it matter where the other piston is?
