Help required please for a wd engine & gearbox

Is there a alloy clutch basket available for this engine

Mine has teeth broken and slots are worn like a zig zag :wacko:

Who supplies gear selector forks for a wd gearbox & replacement gearbox spares.

mine are ground and worn on faces, no thrust washers etc :wacko:

Can i convert 5/8" kickstart to 3/4" splined unit with a wd engine & box ?

Again teeth broken on kickstart gear. :wacko:

Kickstart gear pinions worn need replacements.

What do you lot use for cleaning crankases for removal of old gasket goo.

sorry for all questions but saves time ;)

Burton bike Bits do an alloy clutch basket for the B40 however i wouldnt bother as on a trials bike you hammer the clutch and i dont know but a doubt that the alloy one would last any longer than a std one.

There has been quite a few gearboxs on e bay of late. did you not see them and put a bid in? C & D in Birmingham are quite good for unit BSA parts http://pages.eidosnet.co.uk/~canddautos/index.html

as are Brit Bits http://www.britbits.co.uk/

Will cost you though. sometimes better to buy a complete engine although WD ones are rare.

Best answer i can give is keep your eyes on e bay as there was a lot of NOS WD parts on ther recently

Oh yes you can not easily change the kickstart over to the splined one. Need to bush and machine the crankcases and swap some of the gearbox parts. More trouble than its worth.

C15 F parts fit and some of the lateer B25 bits can be made to fit also.
