Re: 5 min removal of bearing race from crankshaft

Ive successfully removed stubborn tracks by welding an old hub bearing to the track and using my big puller to remove. However I recently did the welding trick but every time I tightened the puller it just broke bits off the track, tried 3 times but no cigar, in the end i had to resort to grinding i...

Re: S3 layshaft slop

Easy to diagnose, with the side case off place a wide bladed screwdriver between 1st gear and the casing give it a wiggle and see if there is any movement.

Ive done a couple recently and have replaced with the excellent Scootopia bearing and track.

Re: which are the strongest lambretta clutch springs

Maybe try a GL3/GL4 gear oil . Or I wonder if you could modify your already modified clutch to take more springs like the BGM 10 spring jobbie, sounds like you’ve reached the limits for 5 springs.

Re: Wossner piston in RB20?

I would leave it to a professional to re peg it, if it comes to that. Not sure who reliably does that. Can't seem to find one stateside. Might be cheaper just to call rayspeed, ask them about it and order the correct piston depending on what they say. The measurement of the piston to cylinder clear...

Best course of action speak to Ben at AF, he’ll put you right straight away, best to ring him after 5.
