Evening all, managed to blow a fork seal at the Bath trial today.I'll get some new ones on order from Hirsts in the morning but I wondered if anyone has any views on what is the best grade of oil for the forks - I "load" the bike with a slender 14st !

My first ride of the A route in the Bath trials excellent trial,just looked at the results,they make interesting reading.(not mine)BTW what happened to Maj man 340 ?

majman has had the boot. Read the ACU bashing thread. He was sussed out. Sorry I can't help with the fork oil query.

I use 150cc per leg of SAE 10, also 14st it works well unless your springs are shot.

Thanks for that,the new seals arrived yesterday,just need to pickup some oil - I'll give the 10w a try.What do you use in the gearbox ? I think I may have mentioned this before but I currently have ATF in there and its not good,before I had 10w/30 synthetic car engine oil which worked well.If there is a hot tip I'd give it a go,cheers Jon.

I'm assuming we are talking Yams here? Most TY's have a tendency to go "stale" in the clutch department and usually if they have been standing for a long time, or the corks have dried out, they will not work at all until the engine heats up and he clutch is fully lubricated. ATF or Dextron is a good clutch lubricant, but once the clutch is working well swop back to the 10-30 and don't overfill. Somtimes you may be better putting new plates in and remember the offset sequence to give a smooth operation.

Yes,Ty250 twinshock,the clutch is in good condition and regularly used for the two years I have owned it.Think I'll get it warm,drain it and go back to the 10w/30.Perhaps change it a couple of times in a row.
