Carlton hydrolics in Rotherham make them. Did mine in 10 minutes, just take an original to gauge the lenth and banjo orientation, excellent quality as well.

Thanks for the replies guys, much appreciated, Since found out that it is about 785mm so you were quite accurate with your measurements. Must give a big shout out to Carlton Hydrolics in Rotherham S65 1SU 01709 378999. Went over to see if they could make me an original looking hose , me thinking that i may have to wait at least a couple of days ,but no, hey presto 10 minutes later I was walking out with a nice new hose freshly made while i wait, complete with rubber cover as per original, all pressure tested as well. Would advise if possible to take sample hose or at least some photos , that way they can copy the orientation for the couplings etc, proper nice people they were and would not hesitate to recommend.

Always worth as i did when i had my pump done is to fit new lines and flush the oil tank clean. Small price to pay for piece of mind. My check valves were letting oil past and leaking onto top engine case from left reed valve housing, then dripping through drain hole and onto bottom case bolt, looked for all the world it was the bottom case bolt that was leaking.

Had some Avon roadriders fitted on mine recently at National Tyres in Barnsley and they only fit Michelin tubes,and they do seem to hold pressure well.

Not a problem tobyjugs, this forum is all about discussing matters, that’s how we educate ourselves, However, the point i am trying to make is simply that a manufacturer will design the clutch to work within certain spec, so if the stack height is more than the designed stack height , for example by adding extra plates then each plate will in theory not separate sufficiently due to the basket not being able to move far enough out when the lever is pulled in, unless if maybe a longer pushrod could be used to give that extra adjustment, conversely as the plates wear adjustment will be made by the cable adjuster as you rightly say.
I make this point because those plates i bought that were not a consistent size created me this very problem, I assembled the clutch with them and still had drag, i could see the problem straight away, the plates were still not fully separating when the lever was fully pulled back to the bar,so bit the bullet and bought the ebc plates which were all a standard 3mm thick and straight away problem of clutch drag was solved . When i measured the cheap heavy duty frictions that i bought with the vernier gauge , the total measurement was about 22.5mm in places, and standard spec is only 21mm for 7 frictions , it was that extra 1.5mm that to me was causing the problem. Hope you can see my point of view. Cheers.

Also, if you wanted to increase the friction area to avoid clutch slip for example on a more powerful bike ,by adding an extra steel and friction, then you would need to make sure that each plate measured a fraction less in thickness than standard spec plates . The aim here is to end up with a stack height the same as the original, if this is not achieved then the plates may not separate and the clutch would not operate.

If the frictions and indeed the steels are thicker than standard specification to the point where this increases the stack height, then the clutch basket would have to move further out and equal to the extra thickness of stack height to be able to separate the plates when the clutch lever is pulled, if this extra pull cannot be gained then this could result in the plates not fully separating, resulting in clutch drag.

I bought some cheaper heavy duty frictions and when measuring the thickness I found them to be ranging from 3mm to 3.13mm in places If you take 7 frictions that measure 0.10mm over the standard size of 3mm thickness then the clutch pack would now be 0.70mm too big,which may in itself be enough to cause clutch drag. The ebc plates i used were all a consistent 3mm thick and for not much more money than the cheaper version i originally bought. Leason learned i think.

I had the very same problem with mine, the oil pump check valve on the left side was faulty which was causing mine to leak, so pulled oil pipe off from left carb and after a couple of days i had a small pool of 2stroke oil,even though engine had never been started, sent pump to arrow for refurb and now problem solved . When mine leaked the oil would drop through the drain channel on top crankcase and collect on the left lower crankcase nut making it look like the oil was leaking from that point . Shaun.

When i decoked my pipes i noticed i had one of each as in the photos above , so i used a pattern fibre gasket to fill the gap with the pipe that had the deep flange then just used the genuine Yamaha copper crush gasket on both sides and along with a bit of silicone gasket sealer and everything sealed perfectly.

My 250lc had the most terrible clutch drag when I bought it, so put new ebc ck2240 frictions in, new standard springs from Fowler’s, new rubber damper rings from Fowler’s, filled the ridges off from the basket and used putolene light gear oil sae75 fortified synthetic and a genuine Yamaha cable, i also fitted new gear change shaft and spent an age adjusting the eccentric screw to make sure every gear and neutral selected correctly, the clutch and gear change is now the best part of the bike, even neutral selects easily from warm or cold even from standstill. The friction plates are the standard size of the genuine Yamaha ones so the damper rings fit in easily and the clutch is so quiet, no clutch slip either. Shaun

Though what you say regarding the cable length Gary is so important, the genuine Yamaha cable I purchased from Fowler’s was about 7mm longer on the oil pump side than the pattern one i was originally using, plus the throttle action is so much snappier with the genuine one... just a shame they are so expensive!!.. but you get what you pay for i guess.

Me too, however mine is an early 1980 model and some pulleys were modified by Yamaha. I have a genuine Yamaha cable fitted and still it rests in the incorrect position at idle according to the previous post, but unlike in that picture where the screw is near the ramp on the inner part of the pulley at idle, mine is well short of the ramp at that position . So at full throttle, I have set mine to fall short of the top mark and now set it at the round mark that is 4 mm below the top mark, apparently this was a secondary mark that Yamaha used to correct over oiling, and at this position the screw is well over the top of the ramp and on the flat part on the pulley , so full oil is being delivered, and this has cured my over oiling 250lc. Hope this helps.

Great reply’s all, went to the local wine making shop and bought some cork bungs for £3 . Put them in the manifold ends and it has worked wonders .Result!!

Hi all, De- coking the pipes on 250lc and just wondered what you use to bung the ends of the pipe. I don’t seem to have any cork or rubber bungs the correct diameter to fit? Without being too rude ,any suggestions would be most grateful . Many thanks,Shaun.

Forget to say it is the rear wheel that I’m working on and i think its actually maybe a dust cover that I’m talking about.

Hi all, bit of advice needed again.. just putting new wheel bearings in on 250lc and the question is regarding the little spacer that slides on left side of the centre spacer?When i took it out that little space which actually is quite lightweight was sitting about 10mm in on the long centre one and i don’t know if this is correct?.. or should it fit flush with the end of the centre spacer so that when it’s installed it would fit flush with the inner hub of the wheel?..Cannot find any diagrams to show this.. any help is much appreciated.. Shaun.

Thanks lads.. yeah all back together now.. frictions all in with cutouts together and steels evenly spaced out.. new standard springs in as well ,at last got rid of my clutch drag ... result.

Hi all, any one know what the little groove is for on the ebc friction plates, there is one at 12 o’clock and one at 6 o’cloc and they are cut on the outer edge of the fingers,? Also when fitting do they fit inline or do I need to space them out evenly as i go. Many thanks Shaun.

With posts like that you’re more than welcome to the forum.. great little film..does take you back.. bad news for buyers however, that’s probably put a £1000 on the price tag of every lc in the uk..haha!!

Yeah I’m aware of that mate, its not that though ,it’s a bit of wobble on where the clutch basket fits onto the centre bush that slots onto the output shaft, there’s a bit of movement, not much, think it might go when filled with oil , hoping anyway!!

Hi all, Just in the process of refitting my clutch on 250lc and notice a bit of movement on the clutch basket when tightened up, the centre hub is tight but the movement seems to be between the basket inner and the inner bush. When you slide the bush into the Shaft it seems like there is no play ,the slight movement is between the basket and inner bush. Just wondered if this is normal at this stage and when filled with oil all will be ok? There doesn’t appear to be any visible wear on the bush or the basket sleeve. Also, Haynes manual states 54ibf ft for clutch centre nut, I take it this is correct!!! ? Many thanks Shaun.

On the plastic bag that the cable came in it did say on the labelling quality jap made cable, and it fits exactly as it should.

Mine is one of norbos quality cables and yes it does have metal sleeves on both sides and fits into the clip under the airbox exactly

Expert help needed again, my clutch basket on 250lc doesn’t have the big o-ring that sits in the grove behind the gear and the back plate , part no on Fowler’s website is 93211-10232. Got all the damper rings that fit between the frictions and steels but not the this one. Question is what does it do and would it be essential to replace it, doesn’t look like the basket has ever been pulled apart because its still held together with what looks like original rivets, so can only assume it was never there or it’s been removed for whatever reason and just never replaced?It isn’t an expensive part and can be ordered from Fowler’s, but just wondered what your thoughts ? Many thanks , Shaun.

That’s good to know mutts, now I’ve set mine i think I will be within +\- 1mm. If I have any set up problems when I get it running I’ll just put everything in a big box and send it all over for you to sort..lol😟
