lineaway Posted September 19, 2015 Report Share Posted September 19, 2015 World Champ, are you saying you have too much oil then to have a quick hook up. Could it be the oil? Quote Link to comment Share on other sites More sharing options...
dan williams Posted September 19, 2015 Author Report Share Posted September 19, 2015 If you don't do anything to lower spring pressure the engagement speed shouldn't be any different for just dumping the clutch. It should actually be slightly faster as the plates will hang less on the basket. If anything the release should be more consistent. Quote Link to comment Share on other sites More sharing options...

dan williams Posted October 5, 2015 Author Report Share Posted October 5, 2015 It's not usually design issues but execution that gets you. Quote Link to comment Share on other sites More sharing options...
worldtrialchamp Posted October 10, 2015 Report Share Posted October 10, 2015 not sure lineaway. ...just found after 3 bike mods the engagement speed tends to slow....I now prefer to have the steel clutch discs linished perfectly flat as a first step even on a new bike. get really strong bite out of the clutch and no dragging/sticking...

dan williams Posted October 12, 2015 Author Report Share Posted October 12, 2015 I agree with flat steels. Patterning them just reduces surface area but several people have had luck cutting holes or oil channels to allow oil to escape faster from under the friction pads. Perhaps there is a need for a design that has a quicker engagement just for pros? Maybe something like a continous pad ring and patterned steels like disk rotors to clear oil. It would be interesting to see what difference having engine driven steels and transmission fibers would make too. Quote Link to comment Share on other sites More sharing options...

baldilocks Posted October 14, 2015 Report Share Posted October 14, 2015 Is that a clutch or just a cover? Dont know for sure but the hose connects to the clutch inspection cover so it must be actuated differently. Quote Link to comment Share on other sites More sharing options...
lockie28 Posted December 16, 2015 Report Share Posted December 16, 2015 Can't you just remove 2 bolts from the pressure plate for a lighter clutch? Quote Link to comment Share on other sites More sharing options...
lineaway Posted December 17, 2015 Report Share Posted December 17, 2015 If you ride the easy line, you can remove two springs. In the real world of trials, it will slip. This thread is about drag, not an easy pull. 1 Quote Link to comment Share on other sites More sharing options...
dan williams Posted December 18, 2015 Author Report Share Posted December 18, 2015 There is a bit of a compromise between pull and slip. For most of us bunny riders the immediate clutch response needed by the experts is not to our benefit. I used to pull two spings but had spacers made up that do roughly the same thing reducing the spring pressure. I don't get significant slip but others have reported it.

italianstallion Posted December 30, 2015 Report Share Posted December 30, 2015 (edited) Hi all, I was contemplating doing this mod but after changing my oil this weekend but have now opted not to. I have an 08 Rev 3 and up until last weekend have been using Putoline GP10. Bike has never started in gear, I could never find neutral when bike is running and the clutch plates always stick/bike jumps when selecting gear starting from cold. I decided to try the Putoline Nanotrans.... Wow what a difference. On first start, plates were not stuck and I found neutral while the bike was running with ease. Clutch seemed far smoother yet sure solid bite. Highly recommended (now £19.99 a tub online so a decent price) Edited December 30, 2015 by italianstallion 1 Quote Link to comment Share on other sites More sharing options...
