If so, then the clutch would’ve been only partially immersed in the oil, so the segments that were not immersed would’ve dried out a fair bit, making the friction plates’ material react against the steel plates differently from those of the segments that were immersed. That might explain the erratic slippage behaviour.
Just a thought...
thank you all for comments and ideas and Im so sorry for not getting back. Took me awhile to find the response email too apart from forgetting to respond.
thats a thought on the oil half submerging also. I really dont know the history of its last start but it should have been recent. I dont feel it would have rust inside as its been stored well. This bike is 10,000 miles and nothing restored and looking great. It rides real well and sounds nice. Its issue is that the coasting light throttle, it seems to run rough. I have held back from cleaning carbs and just putting new fuel through it and its coming on well, albeit not running perfect at low coasting speed.
the issue was that the clutch is driven via the kick starter and the hand level adjustment had no adjustment available and so i went to the engine case adjustment and made it good and gave some adjustment to the lever as it should have had. Clutch worked perfect and maybe i loosened it on the kicks i was doing. starter button works but i prefer to kick it and not wear the old starter out. It starts 100% first kick every time with no choke.
Oil is clean. But i feel there is a screen that needs removing and ask is this come with caution? gaskets? Just preparing for oil change i guess.
We were given a new outer cable for the speedo and noted the old one was qickly failing and speedo was slipping. new outer one fitted and my helper did something? but it now works. However it sits on 20 mph at rest and seems to be equal to KM's at say 50 MPH. So i feel there maybe some adjustment to reset needle position? Odometer works.
One other surprising issue given the museum i bought it from, was the dirty fuel bowl. No fuel would get to the carby. So cleaned it up and note a flat type washer but with 3 fins outwards. then there is 3 or so rubber short tubes located in the fuelcock. When tightening, this makes the fuel tap very tight and in danger of breaking, so i leave it on reserve presently. Should these rubbers come out? Or how can i make fuel tap more easier to move?
Speed. it runs nice in top gear from 50 kmh or less right though to 80 kmh or 48 MPH. Sure it may sit on 60 mph or 100 KMH but Im there for the ride and not the destination. But pushing it harder, it runs out of fuel requiring clutch engaged and by the time i get down to 15 mph then fuel catches up. So something is not right possibly in my fuel tap.
in summary, i couldnt be more happier and now understand why they were a dream back then. the comments of poor handling etc that have been fed to me locally are all out the window as this bike impresses well in handling and power for what could be expected. Brakes are as you would expect for the day and same as the 1970's were also.
thanks for any tips.
