[the_admiral]

hi all again,i am am in the process of fitting new exhaust valve guides on my 81 r65 and i am just waiting for them from motorworks.the old one have come out quite easily with a bit of gentle heat.has anyone got any good tips on reffiting the new ones,i was going to heat the head and put the guides in the freezer overnight.any ideas on a suitable drift so as not to damage them,thank peter

The heat and freeze method should work good and maybe tap 'em in with a plastic or rawhide mallet.

A valve guide drift fits down inside the guide to prevent damage....they came in various sizes.If you know someone with a lathe they could turn one up easy enough.But they should tap in no problem.

Yo Admiral, what caused the need to replace them?
Just curious?

hi thanks for the advice guys,
Amplifier i am replacing them because when checking the tappets there was a fair amount of play side to side on the exhaust valve guide and this could lead eventually to a dropped valve,also she was a bit smokey on start up,cheers
 ps any tips on posting pics anyone
