Hello MBD
I bought this kit at scooter center, on their site and on their photo, the nuts had the same length of screw on both sides,
By receiving the kit, I am aware that there is a bigger screw thread that must go into the crankcase ...
out of these nuts do not screw completely in the housing, which makes that they are a little higher ...
could you give me the maximum length of the crankcase at the end of the nuts so that they do not touch the drive chain?
Thank you very much
Sincerely
Cedric From France

Its best for you to tap the casing a little 7x1mm and fit the longer threads into the casing all the way down to the straight shaft then everything works best
