Thanks, that was a while ago now, ended up with complete crank rebuild and re-bore to 1.00mm o/s as the bores were to damaged to go out to .050mm. the SH engine was a disaster. one standard piston put in a .25mm O/s bore, knackered crank and 3 knackered gears in the box. Sold to me as having worn littler ends!!! but it was a bargain and I got £100 refund after complaining so cost me just £179 for a complete (351) 350 engine. Couldn't even get a casing for that amount now... cheers

Clutch side bearings bad, alternator side ok.

[@bugzie706]

what is the size for the die on the crank threads

[@Charlieswag9000]

Hi did you end up rebuilding the crank yourself? any Idea how to it can be done?

[@mrreallyreally5975]

Hello mate hope this message reaches you just a silly question on the rd350 a/b upper crankcase behind and between the cylinders
(below the carbs)is a hole.What the hell is it for?Any help would be appreciated.MIK

[@ozmadman]

Don't know exactly but I presume it is a drain hole for water maybe that may collect on top on the engine etc as when the cases are together it goes all the way through to under the engine

@@ozmadman sure does, drain hole
