Had a bit of a problem earlier today. Was riding along as you do at about 80 and the engine started rattling terribly. Got home and took the rocker cover off to have a look at the cams only to find that the adjuster for the valve clearance on the second exhaust valve from the left was gone! I can only assume that it's now in the sump and didn't damage the engine when it went through as it was still running rather well considdering. But now i need another one and it's proving difficult. Does anyone know if other bikes use the same adjusters? or know anywhere that might have one? Thanks, Ben.

Try ebay mate you might be lucky.

Ronbinsons foundry or if really stuck Riders of Yeovil will get them.
