clarkp Posted August 5, 2004 Report Share Posted August 5, 2004 I have a suspicion that ATF causes the clutch fibre plates to swell thus causing all clutches to drag since there wouldn't be enough 'throw' to adequately separate the plates. Anyone have any experience with this? Is this on track or am I smoking left-handed tobacco? I've switched over to Mobil 1 synthetic and away from Torco MTF 75 - the Mobil 1 seems to help a little with the clutch dragging. I think a wholesale switch to new fibre AND new steel plates along with the Mobil 1 should give me a perfect clutch for the upcoming fall season. What are you running in your bike?

charliechitlins Posted August 6, 2004 Report Share Posted August 6, 2004 According to some folks on this list, ATF can definitely swell your clutch. Maybe even cause the fibers to come unglued from the plates. I'd say it's best to avoid it. Quote Link to comment Share on other sites More sharing options...
dfwilson Posted August 6, 2004 Report Share Posted August 6, 2004 (edited) I use Mobil 1 Synthetic ATF. It works great all year round. Last weekend at the Trialstasia event it was 100 deg F. Not a rattle from the gearbox was heard. The stuff works great in the winter also. Edited August 7, 2004 by dfwilson Quote Link to comment Share on other sites More sharing options...
rlracer Posted August 6, 2004 Report Share Posted August 6, 2004 I use Ipone and have used some maxima both with great results. Could it be that red river dirt in Tx, ha ha. Quote Link to comment Share on other sites More sharing options...
clarkp Posted August 6, 2004 Author Report Share Posted August 6, 2004 Interesting reply, Charlie... when I installed the SureFlex clutch plates in my old Montesa, several of the fibre 'pucks' had delaminated from the plate - I was never sure why. I do know that the previous owners of both my Montesa and my Beta had used ATF in the transmission. Quote Link to comment Share on other sites More sharing options...
