Try JSL ,if they dont have new/reconditioned ones they probably have some second-hand ones.

Hi Per,
you could also try AMC Classic Spares they have loads of second hand stock.
Yes, Ian did mean Jampot Spares Ltd.

Hi, and welcome

I would investigate why/how they have been bent, to my knowledge this is not a common occurence...

If the rockers were bent when engine was running I'd be very surprised if there isn't damage to push rods or possibly valves.To bend rockers, which I thought were cast, something must have made contact which shouldn't have due to incorrect valve timing etc.

I think the rockers are steel forgings probably of fairly high grade material so they can be locally hardened on the heel or pad that makes contact with the valve stem.

The valves has been eating in the valve seat sow mucht that they suddenly came in contact with the rockers. Two off the rockers-push rod have been bend.
This happend after a ride over 2 hours,but i did,nt realy now the engines condition. The bike hasn,t realy been on the road for 10 years.
I have now sendt the top too an expert in norway for new valves and seat, i took the cylinder off too, for bying new piston rings but my cylinder measure 67,55mm. Should i by +60 ? And do the rockers fit my enginges when the parts number don,t match.?
