I contacted birkett motorsport, nigel and his wife were extremely helpful, all parts I need in stock and an alternative crank pin on the shelf as Yamaha did stop making them. It’s good to know spares for the sy are still readily available.

I’d be suprised if there wasn’t something available as an aftermarket kit, a few people have mentioned about the yz 250 being a possible match but just need this to be confirmed, ive emailed a few trials bike dealers and need to ring a few on Monday, if I find out I’ll post back here for anyone in the same position.

Yamaha sy 250, I haven’t tried birketts yet I’ll give them a ring on Monday see what they say, apparently Yamaha stopped making them so it’ll be old stock if I’m lucky enough to find one, or if anyone has had any luck with a suitable alternative

I can’t find an oem or aftermarket Conrod kit, ive sourced all the parts individually except for the crank pin

I’m planning on giving my scorpa sy a full engine rebuild for a project over winter, I have the crank out and planning on sending it away to get rebuilt but the only part I’m struggling to find is the crank pin that sits inside the big end bearing that’s pressed in, would anyone know of any alternatives from other bikes? Or anywhere that might still have any?

I'm surprised these have never leaked as they hardly seal into the clutch case, i have them on order with other bearings and seals while I have it apart

Thanks for the info, if its normal for a little play in the basket I will leave well alone before I break something! I'll fit the new clutch and check everything again after several oil changes and see if theres any change with it.

I'm currently putting a new clutch in my bike, but on removal of the old clutch Ive noticed the clutch basket has some play in it, probably 1-2 mm does any one know if this is normal? Or am I looking at new bearings? I noticed it's a allen bolt holding it in which look like a pain to remove. Any help is appreciated

Hi, does anyone know a link that works for an online spares manual for the jotagas 300 2013?
