ggg Posted July 23, 2023 Report Share Posted July 23, 2023 gas gas 2002 20cc txt pro - what fluid is used on the clutch and rear brakes systems? Quote Link to comment Share on other sites More sharing options...
lemur Posted July 23, 2023 Report Share Posted July 23, 2023 DOT 4 brake fluid in the brakes available at auto stores Are there any farm tractor or heavy equipment dealers near where you live? For 2-stroke transmissions with wet clutch I use all season hydraulic excavator oil ISO46 and replace it frequently because it only needs about half a litre. Been using it for decades without problem in 2-stroke transmissions and Montesa 4RT transmissions. Quote Link to comment Share on other sites More sharing options...
lemur Posted July 23, 2023 Report Share Posted July 23, 2023 Now you went and made me think it's due time to change all my fluids, I've been riding her hard lately. ... flush the hydraulics and sand down the brake pads ... buy a new chain ... service the air cleaner ... service the forks 🙄 awcrap I have a lot of work to do this week.

carl ekblom Posted July 24, 2023 Report Share Posted July 24, 2023 Some models of GasGas use mineral oil. Consult the manual (or importer) and use the same oil, or at least the same type of oil. By the way, Dot4 is used on a lot of trials bikes. Quote Link to comment Share on other sites More sharing options...
turbofurball Posted July 25, 2023 Report Share Posted July 25, 2023 The 2002 Gasgas TXTPro uses DOT4, yeah. For gearbox oil I use Dexron 3 ATF fluid, really helps with sticky clutches. Quote Link to comment Share on other sites More sharing options...
richt Posted July 25, 2023 Report Share Posted July 25, 2023 It was late 2005 when they changed the clutch from brake fluid to mineral oil. I use Dexron III ATF in the gearbox. Quote Link to comment Share on other sites More sharing options...
lineaway Posted July 25, 2023 Report Share Posted July 25, 2023 Actually it was on the 2004 Raga. Originally they changed to the green lid in the clutch m/c. But anything can happen to a bike during several decades. Quote Link to comment Share on other sites More sharing options...
richt Posted July 26, 2023 Report Share Posted July 26, 2023 Yes you're right, The Raga replica models were a year infront of the standard models but there are fewer of them! Quote Link to comment Share on other sites More sharing options...
