basher Posted January 23, 2012 Report Share Posted January 23, 2012 well here goes. ive got a 2011 raga rep 300cc. ive come from a sherco and i loved the shercos clutch it suited me and my riding really well. the clutch was pritty quick in engaging and didnt have that much progression. ive gone on to this bike and hate the clutch, its way to progressive. even on full adjustment the clutch only just starts to bite near the knuckle and i am dragging the clutch quite alot on somethings when i dont want it to. ive tried bleeding it and still no difference. ive been looking into it in the last day and have found out that you can change the spring height of the fingers which will give it a slightly harder feel on leaver but will also give less progression. at the moment it measures 17.9mm on average around the fingers. i believe you can go lower down to 16mm. my question is what plates do i need to get it down? they do a 1.3 1.4 1.5 i believe. also any idea how much the plates are? cheers for any help Quote Link to comment Share on other sites More sharing options...

basher Posted January 23, 2012 Author Report Share Posted January 23, 2012 i dont really want to go down that route really, alot of mony for bling really, and it seems a naff way of adjusting clutch using o ring seals. ive just measured the clutch pack height and it measure around 9.74mm if i change the plates then surely this will then mean the clutch pack height measurement is out. does this not really matter and im still ok to change for different plate to get closer to 16mm??

laser1 Posted January 23, 2012 Report Share Posted January 23, 2012 The thicker the pak - the lower the fingers will be. What oil are you using? ATF-F will give the hardest bite. If its cold out, you will get more drag. for less drag, make sure you dont fill more than 1/2 up the site glass. (375cc - but change it often) Some of the local GG expert riders here are all changing to the Jitsie levers to make for a slightly faster clutch. (I have no personal experience with this mod, but can find out more if you like - but they swear by them) If you really wanted it even harder engagement - you could try a 05 spring. (20% stiffer)But would have a correspondingly harder pull. (like the Sherco IMO) Quote Link to comment Share on other sites More sharing options...
basher Posted January 23, 2012 Author Report Share Posted January 23, 2012 it had castrol dexstron in. ive just had that thought myself so changed it for some putoline gp10 75w i ran that in the sherco fine. ive put about 420ml in. little hard to tell as i spilt some. ill have a look how far up the glass it is. how does this work out tho. i measured the 2 plates and there 2mm thick each so how can i switch to different thicker plates when they only go up to 1.6mm? would be great if you could ask about the jitsie levers please. ill have a look at them. i never found the pull was that bad on sherco. and it wasnt like a full on switch the clutch, it did have a bit of slip but just no where near the amount this gas gas does.

The third fiber plate was thicker and the thickness was chosen at the factory to adjust the pack thickness upon assembly (this thicker plate is always put in the clutch assembly first). This was different from the older types that had three fibers of the same thickness and the steel plates were chosen to adjust the pack width. The steel plates came in 1.3, 1.4, 1.5, 1.6 and although I've been told they are available, I've never been able to get them, a 1.8mm. Your problem lies in the fact that you already have 2mm plates so the adjustment "shims" will not do you much good at this point as you want to increase the width of the pack a little. Since most Trials riders are packrats and save just about everything just in case they "might need it later" (o.k., I'm the only one who does that....) you might ask around to see if anyone has an old clutch pack they took out. Provided the old pack is in halfway good shape, you could then measure that thick fiber plate to see if you can replace one of the thinner plates with it. I know it sounds a little Mickey Mouse to do it this way (I've tried it and it worked fine) but you can always go the different leverage levers and S3 sidecover later.

laser1 Posted January 24, 2012 Report Share Posted January 24, 2012 I suggest you try 375 cc of cheap ATF-F. (Cheap makes it easy on the wallet to dump often and works fine) I have a email into my buddy for the Jitsie part number. Another rider who uses them reminded me that the change isnt night and day - but is an improvement. Quote Link to comment Share on other sites More sharing options...
basher Posted January 24, 2012 Author Report Share Posted January 24, 2012 That's brilliant advice cheers. Ill just buy a new set of plates off john shirt and make sure that they send them with a thicker fibrer. It has standard long levers on so ill change them. Looked around and can't find these jitsie levers anywhere. I think ill try the bendy rfx ones first as a lad at comp on sunday had same bike and clutch was better but I could tell lever was heavey feeling so more than liekyl he has got lucky and plates have swelled abit. Ill try the bike tonight with this oil I've just put in and see if there's any difference. I change it every 3 rides anyway. Quote Link to comment Share on other sites More sharing options...
