    Changed the cam chain over on the cbr900rr. Engine sounds sweat now but clutch is still noisy at low idle speeds (rattle/clunk). Suspect clutch damper springs are in need of replacement.
    Anyone ever rebuilt a clutch basket and replaced these springs. The clutch basket is an expensive part and now hard to come by.
    Maybe there are clutch repair business that could do this. Any advice welcome.

    Never done it myself but the idea is to drill out the rivers and remove the primary gear from the basket to access the dampers. The springs also rattle with age. I put a new basket on my ZXR250, it didn't help in my case. Never found the cause of the rattle, had a top end rebuild, clearances, can chain, tensioner and throttle balance, still rattled. I suspected the water pump/oil pump shaft had a broken fork but I never pulled the engine that far apart to check. When under load and moving it was fine.

    Got a picture so I can have a look?
    May be able to shim the springs with a washer.

    Unless it is just in need of a carby balance?

    C5DE984F-07DB-4412-AD7D-32E7F68AB06B.jpeg Trailered home the GS1100 from a ride in the Border Ranges. Lost all electrics suddenly. Battery fine, fuses good, couldn’t find loose connectors. Sent mate on MV for trailer. Oh well, first time in its 125000 km and 37 year life. What happened to good old Japanese reliability! Now the search begins. Any suggestions? I’m not too good at electrickery. Too sudden for the old GS alternator/ regulator problem.

    Key? Starter relay? (There is fuse there, check connections and continuity/power supply) Good luck

    Do you have spark ?

    remove a plug from the motor , insert it into the coil cap then ground the plug against the side of the head and try to start it , yiu should see a spark from the end of the lug.

    Do you have 12v at the coils
    I have heard the kill switches on gs1100gk’s playing up, maybe pop it off and clean the contacts , also as Shane suggested it could be an ignition barrel issue

    Hi Guys, I do not have the clutch basket out of the bike yet, but this is what I suspect is going on.

    At low speeds, any jitter in engine revs tends to make the clutch basket assembly rattle and cluck as the uneven torque load is transferred to the gearbox. Pulling the clutch in silences it.

    Thanks Kiffsta and ShaneP for suggestions. Dragged the sealed battery out this afternoon, with great difficulty- it had swelled significantly jamming it in. Seems like I may have the dreaded Suzuki charging problems after all. So, new battery, and then check on stator/ regulator situation. Probably fried them.

    Bought a hyosung gt250r for wrecking , the previous owner made an interesting choice for his battery

    Cleaned up the workbench... I have an issue with utilizing every horizontal surface as storage. Once that was done, started tearing down of the 96 mc22 motor. Taking lunch now and glancing over the factory service manual to see if I can get a hint as to the proper order of pulling parts to keep things simple. Hoping I can talk one of the local shops into loaning me the castle nut wrenches I'll need instead of me trying to make the tool myself/spend money on something I'll likely only use once. Of course I realized as soon as I started pulling parts off that things like the clutch basket would likely be easier to remove while still in the bike, but it is what is...and I have an uggdugga so odds of me winning in either case are high.

    The only hard to get bolts are the ones under the cam gears in the tunnel at back of head, other wise they are a relatively simple engine to work on. Have fun.

    I try to fit one in, 2 weeks & counting, the coupling gear / oil pump drive / pulse generator house is getting closer to being complete, a few more 5mm screw holes to drill & tap to hold the outer cover / pulse gen mount lump of 3mm alloy plate & I can do one more trial fit before making it all purdy & bolting up for the "last time" , with Yambond, although I still have to mount the crank extension & oil pump drive extension support bearings & oil seals before moving on to fitting the carbs.
    If I get around to a build diary, it'll be from the beginning, with a few repeat pics + some boring chop chop ones thrown in, I'll try & coax my thoughts out of the memory banks to try & explain,,,why ?

    Have already had those out once so I guess it's easy sailing from here? Famous last words, I know.

    How terrific are MC-19's.
    My little bike was last used at the March 2020 drags and has sat untouched until today. I drained the fuel from the carbs and tank after the last meeting (as I always do, just leaving some in the fuel pump to keep wet) and placed it in the shed. The next two meetings were cancelled due to the virus scare and by the time of the November meeting I was in Newcastle hospital recovering from a crash.
    This year I was unable to make the March meeting as I was getting over the brain surgery, and now it is May and fourteen months have elapsed since the bike last moved or was started. Today I moved it into the middle of my shed and put on the rear stand. Checked the oil and coolant, all good, poured in four litres of fresh petrol, turned the tap on and primed the fuel pump to fill the carbs, full choke, no throttle, switch on and two winds of the starter and it fired into life. About twenty seconds later I pushed the choke off and it just sat there idling happily. Gave it a few moments to warm and gave a flick of the throttle, clean rev to 8,000rpm and drop back to idle. What a brilliant little bike.
    All ready for an exciting weekend at Gunnedah.

    While I have not had the pleasure of owning a CBR250, I do often find that Hondas tend to be easy starters after long periods of rest. Today, I went for a ride with a CBR250 owner. His bike had been stored for awhile and when started decided to only run on 3 cylinders. A quick squirt down the road and number 4 decided to join the party and off we went. Not sure that would have happened with a Suzuki or Yamaha. Might have something to do with 4-stroke engines with Mikuni carbs versus the other brand that Honda own.
