Hi All,

I have bought EBC Heavy Duty friction plates, new cable to eliminate my clutch starting to slip. 11,000 miles and first change i believe. The clutch engages when the pull lever is pushed forward so probably just the 10 year old cable.

Are EBC HD clutch springs worth it or just a pain in the hand/wrist?

Do these require special tools for the oil spinner removal and clutch plates?

Every time I start a project I get caught out needing something.

Thanks for any links. Rolling Eyes

Just change the cable. Clutch plates should be fine as they are, and everyone seems to cock up their first couple of clutch plate changes. You'll break it by trying to fix a problem that doesn't exist.

Pro tip for changing the cable. Leave the existing one in place, and route the new one in alongside it. Connect up the new cable and adjust it (bottom adjuster for most of the adjustment, top one only for fine tuning), then remove the old one.
This means your new cable is correctly routed.

Changing the clutch on a CG is an easy job. As above change th cable first and if it's still problematic look at the clutch itself.

If doing the plates I think you're as well to do the springs too. Do it right and you won't have to go back in there for a long time. There is a special tool required for the oil spinner. You can buy them cheap on eBay or make one easily from an old socket.

Cable routing tip above is a good one but not really necessary on a simple CG, and it relies on the old routing being correct.

Worth it or a 15% extra pain in wrist/arse?
What did you lube a 10 year old clutch cable with a happy ending.
A new cable + lube for the next 10 years, suggestions?
Can I beat the engine oil as a inner cable year round lubricant?

you need a special tool. Honda Service tool, 07716-0020100, a socket for a slotted nut, on the end of the shaft in the middle of the clutch.

New springs would be a good thing. See How2 and how short old ones were.
I doubnt that EBC HD springs will make the clutch Guzzi stiff!

I'm a bit surprised the CG clutch is knackered in 11000 miles. It's a pretty sturdy little beast with barely enough power to wear out a clutch that quick unless it was being abused by a complete knacker.

EDIT - re-reading Op's first post in the thread and he answers the question himself - its the cable. If it isn't rusty, just lubricate it and work it up and down a bit and see if it frees. If not, then new cable. Keep the new clutch plates safe for ten years when the actual clutch wears out.

Buster: -The average M/C these days only covers around 3ooo miles a year. 110000 miles then is most likely round the clock 99,000 miles, Plus 11,000.... and the equivilent of 36 yeaars average miles or perhaps five to seven total life-miles for any motorcycle...

He says the thing is a 2008 model.... so at least ten plus years old.. has it been clocked in that time? Not impossible, these things can rack up car type annual miles in commuter service, but ho-hum. Its no spring chicken, and Learner/Commuters rarely have the most contientiouse no expense spared owners looking after them! Would only take a couple of oil changes IF its owner was even THAT contientiouse, stucking in copper or molybdnum addadive or cheap supermarket, addadive containing car oil, to lube syncro-cones in car/type gear-box, to eff up good clutch plates;

whilst learner clutch use can be horenouse...

One comes past my house regularly and I wanmt to go out with a base-ball bat and teach them how to use a clutch properly! Four gear changes in 200 yards in a 20 zone!! and banged twixt each, never letting the clutch out fully, its slipping the whole way up the road FFS! Theres another, probably CG copy that will need new clutch plates earlier on!

Vis the rest; replacing the plates and springs is not a bad bit of preventative maintenence. Meanwhile a new cable, at aprox 10-15 is cheap enough to just do and be done with rather then faff around trying to work oil down the whole length and stay there..... itrs probably cheaper then a cable luber amd a can of swuirty oil to try and recover the old one with stretched strands and loose nipples....

Teff.

The OP reports the bike as an eleven thousand miler not a hundred and eleven thousand one. I'd like to see the round the clock cg125, by the way. It should be in a museum of amazing machines if it exists, though I did meet a guy on Facebook who said he had been commuting on a couple of these bikes since they came out and he had one with 80 odd thousand on it and one with 62 thousand and neither of them had had any internal work, just thousand mile oil changes and tappets and normal routine servicing.

Its true that a lot of CGs are hammered by youngsters who dont' even think of maintaining them, but there are plenty that are genuine low mileage bikes that have been in a garage for a decade and more. I've actually got one like that, though I put 6000 miles on it in the last year. It was an 18 year old bike that had ten thou and a few when I got it in May 2018 and now it has 17010 on the clock. The MOT history database online is useful in checking mileage history and previous faults.

My money is on a grotty cable. The clue is that he says the clutch engages when he pushes the lever forward.

Certainly worth starting there and replacing or sorting the cable before breaking open the clutch side casing.

By the way - a question for you:

I just got a low mileage cb250 nighthawk - 12000 miles. Am I right in thinking these have an oil screen inboard of the oil pump? Do I need to crack open the case and clean that at 12000 miles. The engine is a peach. Very smooth and quiet, so I don't want it knackered by oil starvation.

CG was launched to market in 1977....

Well, I may still be a youngster from your lofty view-point.. b-u-t.... I dont think that age has a lot to do with it.... the curse of the See-Gee, is the ide that 'low maintenence' means 'NO maintenence', and there's as mamy more mature and aught know better, owners as guilty of that as there are teen-agers! If anything, teen-agers nieve enthusiasm and 'fiddle-fingers' is likely to see them treat the thing more like a lego set and get the spenners out more often than an older owner more want to treat it like a washing machine and not do a thing but ride it till it starts making funny noises or conks out, when they call a washing machine repair man....

You may be right.... but I still say that a new cable is a more sure fix than trying to recover a chitty old cable with stretched strands and loose nipples and eons of goop down the sleeve.... and in for a penny in for a quid, mnew plates are not a bad bit of precautionary, and pulling the primary cover, is nowt else, at least demands a proper oil change! Its worth the doing for the cost/effort/time, its not an inordinately difficult, expensive of time consuming job.

I'd clocked that acquesition.... I think you likely paid rather over the odds for it... but still....

YES, its a Benly.. should have been badged as such, especially having single carb not twins like other See-Bee, badged offerings from Sochiro....

HOW2: change Oil & CLean strainer (Small Honda's +)
http://i178.photobucket.com/albums/w269/teflons-torque/Little%20Dreams/LD07%20Eng%20Build/100_0476.jpg

I'd do a thorough flush with derv/parafin, and a squib of fairy liquid in the old before dumping it, and on an older lkow miles long laid up example I would be as worried about firred rings in the piston/bore as excessive wear, and rejuvenation failure as soon as more usual miles put on the dang thing...... Prerrt sure Chinky barel kits are available for the 53/53 big-bore enleys, and I think that there's even a 300cc kit around for the quads, that would drop on nicely, though probably not liberate any more than its meager barely learner legal 19bhp...... may be worth lining one up for future winter project?

Thanks for that. Looking at that strainer, I will get at it soon. It was owned by a man in his seventies and early eighties and a life long motorcyclist.His son bought it for him after he fell off his 800 BMW at age 72 and was embarrassed because he couldn't pick it up. I am hoping he probably took a serious approach to maintenance, so it was hopefully done at the recommended 8000 miles.
