taninthai Posted May 17, 2017 Share Posted May 17, 2017 little problem just really noticed yesterday,,,,,,,if I'm in 1st gear with clutch pulled in the bike will not roll backwards, getting a lot of resistance and a grind noise, also noticed if going along and say slowing for a turn pull clutch in and get a kind off whirring/whizzing noise............there is no clutch slipping when accelerating and no problem with any gear changes. do you think clutch on its way out.....the little winder by the lever is wound all the way in, if i wind it out a bit start getting clutch slipping on acceleration,,,,,,,the biting point fro clutch is about middle of lever position........any advice or views........appreciated Link to comment Share on other sites More sharing options...
BBJ Posted May 17, 2017 Share Posted May 17, 2017 (edited) Does the rpm match its increase in speed? Shaft or release baring. May just be worth changing the clutch. How many miles has it done? Personally, I never wait for the clutch to go. I change it when I think it need to regardless of signs. Edited May 17, 2017 by BBJ Link to comment Share on other sites More sharing options...
Kwasaki Posted May 17, 2017 Share Posted May 17, 2017 Without looking at it myself, if there's a free running clutch cable l would say from what you describe is a worn out clutch. Link to comment Share on other sites More sharing options...
taninthai Posted May 17, 2017 Author Share Posted May 17, 2017 20,000km rpm matches speed increase ....shaft or release bearing?????? Link to comment Share on other sites More sharing options...
VocalNeal Posted May 17, 2017 Share Posted May 17, 2017 (edited) Have you changed to a different oil recently? Doesn't explain the noise which is likely the release bearing but different oils perform differently. If so go back to 10-40 Honda oil. Try ThumperTalk or take it to Honda?

ktm jeff Posted May 17, 2017 Share Posted May 17, 2017 If you go for a clutch change , look up / Google the clutch plate modifications , which i believe involves fitting an extra clutch plate in place of a "beveled" plate. Many people identified this plate as the main culprit in many clutch issues. Keep us informed. Link to comment Share on other sites More sharing options...

Gnasher328 Posted May 22, 2017 Share Posted May 22, 2017 I had a 300 conversion on my CRF (might bring problems of it's own - crank recall!). It felt like the clutch was always on the verge of slipping so I bought and installed a CBR300 clutch pack - cheap and easy. Link to comment Share on other sites More sharing options...

Gnasher328 Posted May 22, 2017 Share Posted May 22, 2017 Done by 'The Monkey Father, in Chiang Mai. Can't remember what it cost but with the std exhaust 'gutted' it was well worth it, totally different bike. Got the guts to get through the horrible 1st-2nd gap on steep trails now.

The 250s have a half plate-spring thing, the 300s don't which is why you buy the 300 parts. Fairly cheap at the Chiang Mai Honda parts place.

Gnasher328 Posted May 23, 2017 Share Posted May 23, 2017 Hmm, wonder if mototh have got it mixed up? I can't see why Honda would effectively weaken the clutch of a more powerful bike? Unfortunately I just had a cleanup of files and deleted the official Honda parts breakdown I showed the Thai supplier - but they were all full plates!

You definitely use the springs from the CBR300...but why they chose to put the judder spring in that and not the CBR250 is anyone's guess Full list here... CBR300R Clutch This is a breakdown of the CBR300 clutch (items #7 and #11 are the judder springs)... Link to comment Share on other sites More sharing options...

Gnasher328 Posted May 23, 2017 Share Posted May 23, 2017 I keep telling you - I didn't use a judder spring, the diagram I showed the dealer -official Honda - had full plates in it and that's what I got and fitted! Link to comment Share on other sites More sharing options...

And while we're on the subject... There is a judder spring in the following models: CRF230L CRF250L/M CBR300R CB300F CB500X NC700X CRF450R CRF250X CRF250R There isn't a judder spring in these models: CBR250R CB500F XR650L CRF450X GROM 125 So what determines which bikes get judder springs and which don't in Mr Honda's eyes Link to comment Share on other sites More sharing options...

Anyway they want 47 dollar just to deliver that clutch and spring set........I take it Honda don’t use ebc kits think I’m gonna just order the the 250r plates and 300r springs from local dealer or sunset cycle .....will have to check prices Link to comment Share on other sites More sharing options...
