VIFFR Posted June 29, 2013 Share Posted June 29, 2013 Im looking at getting one of SebSpeeds clear clutch covers in a month or so. Whilst it is all apart, I figure I would replace the clutch springs with a heavy duty version. Does anyone here recommend a brand they have used or know about? Cheers!

Member Contributer mk2davis Posted June 29, 2013 Member Contributer Share Posted June 29, 2013 On other projects I've had to shim the springs with washers. Not very elegant, but it worked. That may not be the answer you wanted, but maybe some nice stainless? Link to comment Share on other sites More sharing options...
Veefer800Canuck Posted June 29, 2013 Share Posted June 29, 2013 I used EBC springs with mine, not sure if they are heavier than the stockers or not, but they're working fine...... Link to comment Share on other sites More sharing options...
Member Contributer mk2davis Posted June 29, 2013 Member Contributer Share Posted June 29, 2013 Are you pulling considerable more power than stock? Link to comment Share on other sites More sharing options...
CandyRedRC46 Posted June 29, 2013 Share Posted June 29, 2013 I have been running barnett 100 pound clutch springs in my bike for a year or so now. It makes for a heavier clutch pull, but much more progressive launching and take offs. The pull at the lever is not bad most of the time, but it gets tiring during heavy traffic. On the other hand I was able to raise my launch rpms at the track from about 4000 rpms to over 8000 rpms. (even higher with fork straps, but that's a different story) http://www.ebay.com/itm/Harley-Barnett-red-clutch-springs-MT-91-6-new-/130840037710?pt=Motorcycles_Parts_Accessories&vxp=mtr&hash=item1e76ac894e&ssPageName=RSS:B:STORE:US:101 Barnett Springs-99lb-#MT-91.

Member Contributer CornerCarver Posted June 29, 2013 Member Contributer Share Posted June 29, 2013 yes. if you are just going to replace the springs go with Barnett or EBC but do disassemble the clutch pack and scuff up the steels if after inspection you determine to continue with the stock fibers and steels.

spud786 Posted June 29, 2013 Share Posted June 29, 2013 I have over 100,000 mile oem clutch, why do you need heavy springs, your hand need more of a work out? Link to comment Share on other sites More sharing options...
VIFFR Posted June 29, 2013 Author Share Posted June 29, 2013 Hi guys, thanks for the replies. Its a fairly stock bike, staintune, airbox mod, K&N filter and sprockets. A pcIII is on its way too. The main reason I am looking at heavier clutch springs is I don't really like the feel of the oem clutch. Its too light. Ive ridden a mates bike who had his changed (Kawa 600) and was really firm and had a great feel to it. We do go drag racing on a regular basis too, so getting 6 runs on a Wednesday night, or up to 12 on a Sunday, its bound to take a bit of a pounding. End of the day, Im changing it out (I've decided to change out the clutch pack whilst its apart) purely as I would like to. Its going to be exposed, its only costing me $150 for it all and its only another few hours work. Link to comment Share on other sites More sharing options...
Veefer800Canuck Posted June 29, 2013 Share Posted June 29, 2013 If your steel plates are still good, not warped, overheated, scored or worn thin, then you can bead blast them and reuse them. I just changed my frictions and kept the OE steels, they were fine. http://www.vfrdiscussion.com/forum/index.php/topic/68154-clutch-and-grab/ Link to comment Share on other sites More sharing options...
CandyRedRC46 Posted June 30, 2013 Share Posted June 30, 2013 i strongly recommend oem plates with the 100 pound Barnett springs if you are drag racing. i have not had good experiences with aftermarket clutch plates. also with heavy springs, the oem clutch is capable of handling more power than you could ever even dream of throwing at it.

Member Contributer vfrcapn Posted June 30, 2013 Member Contributer Share Posted June 30, 2013 Welcome, great looking bike, love the matching wheels! I've got a Seb clutch cover on the way too and need to make some decisions on plates & springs. Link to comment Share on other sites More sharing options...
Member Contributer Dutchy Posted September 24, 2014 Member Contributer Share Posted September 24, 2014 Reviving an old thread since -while I was sourcing some parts for a US member- I ordered a set of heavier "by 10%" springs. Last time I measured the OEM's were well in spec, but with Seb's clear cover it is easy to switch and try them They come in a pack of 6, so one will make a nice key fob... OEM's are 44.4mm These measure 45 and a bit Saturday sees the "VFR NL Forum Wrench Day" so will fit them then Link to comment Share on other sites More sharing options...
CandyRedRC46 Posted September 24, 2014 Share Posted September 24, 2014 i doubt you notice the ten percent at all. i think the stockers are about 50 pounds, i tried 75 pound springs and they helped with clutch modulation but there was still some chatter. the chatter didnt entirely go away until i installed the 100 pound springs.
