Hi, and great video ,I'm having a similar problem where as my m21 go's into 1st,nutral and 2nd but that's it so would this adjustment something I should try and will it throw 1st and 2nd gear out,if you could help and advise it would be most appreciated ? thank you Russell.

Maybe, I got mine working OK after some trial and error with the adjuster. Problem was having to remove the exhaust, footpeg, and drain the oil. I ended up putting the outer case on with a dry gasket and no oil (it took 3 or 4 times) until I got ot working OK I even took it for a short road test before sealing the outer cover and putting the oil in. I hope it works for you, Cheers B

A very neat job Brian. I'd be lost without the lathe. Best wishes, Dean.

Thanks Dean, cheers. The drain plug pissed out, back to the drawing board.

@@500dbd34 That's a shame. Perhaps you can regrind the taper between the case and the original plug? Best wishes, Dean.
