Hiya Chris, Mine is a 1969 250 with 21 tooth sprocket. Didn't realise the thread was metric. If so i might be able to borrow one from my local bike shop. The puller for the flywheel has a three bolt fixing with threads that seem to be about 5 or 6mm. If it is stefa would these be metric. Cheers. Mick

If its a 3 bolt fixing for the extractor than you could either make one up from a piece of scrap steel plate & some bolts, or buy a universal one like this http://www.ebay.co.uk/itm/Flywheel-P...item2c699e610d

Thanks John,
Although i have managed to remove the flywheel i have just ordered the puller shown as i think it would be silly not to. It's reasonably priced and looks a fair bit of kit. The problem i have now is finding a puller for the front primary sprocket. As far as i can make out its 35mm internal thread(measured with vernier). All the ones on ebay that iv'e seen only go up to 27mm. Mick

Cheers John,
Taken the gamble and ordered from the second site. Just hope sprocket thread is metric. Will let you know if not when it arrives. At least i can use it for bass fishing off the rocks if it doesn't.
