I've just furnished myself with an '04 TXT Pro 250. I know the question has probably been asked a gazillion times before, but just humour me guys. I've read and been told that G-G recommend NOT to use Silkolene products. So the question is, is there a particular oil that suits these engines, or will any good fully synthetic oil do?

Do not use any synthetic engine oil, it can swell the fiber clutch plates!

All your info can be read in the 'Tech' section on the trialspartsusa website

For gearbox oil use Castrol TQ-D (it is actualy ATF DEXTRON III)

and for fueloil I use 'TTS' at about 70:1

Ok, thanks for that Rich.
