well, its been a while since the A10 last ran, probably 3 months!! been sat on the ramp waiting for me to do something.
drained the sump as emptied the oil tank. re sealed , charged the battery tickled the carb , kick, nothing. tickle again kick, kick back!! prommissing. tickle again, another kick and starts up not much blue smoke either... *smile*
all good, must get it MOt and Taxed as required, free tax no mot, and its insured.... *smile* ;)
bugg3r leaking out from behind the chain case now where the final drive exits.... *angry*
suppose that means clutch strip , ah well looks like another couple of weeks off the road....
normal weather will have resumed by then. *conf*

chaz, just check that oil hasn't weeped into the P/chaincase whilst it's "been off the road " mine did and I ended up with the stuff everywhere,it could easily have enough to pump it out the mainshaft hole in the case ,worth a look and could be out this affy in the sun, regards BobH

yes Bob, drained the primary this evening and took out best part of a pint..
so hopefully that's that, next question is would that amount of oil stopped me being able to select a gear, holding the clutch ?
-
G'day Chaz, yes it would if the clutch was slipping due to too much oil.
Cheers

Oil wont "hold" the clutch enough to stop you selecting a gear. Did you free the clutch off with the kickstart after it's lay up?
-
My clutch plates get 'glued' together; I've just had to strip the clutch again and seperate the plates with a screwdriver.
I have the plunger type six spring clutch with a domed cover; the clutch is dry inside that. However, my clutch bits have been laying around in my garage for many years. I washed them in petrol while restoring the bike. I wonder if some jollop is coming out of the lining material when hot and then setting.

only three kicks and it started up but have probably pulled the lever in a few times since last started

Pulling the lever won't necessarily free a block of stuck clutch plates, all it's doing is releasing the pressure on them.
Greybeard, I have heard of the friction material bonding "glue" doing just that on the dry clutches.

Chaz, just try this easy way to gauge what the clutch is doing . Without the engine going stick in 1st or second disengage clutch and press down on kickstarter. Has you swing her over initially there may be some resistance caused by oil/ plates and it should free off ,you'll feel the degree of drag and if it gets easier should be okay if not readjust the clutch by a combination of cable adjusters and/or pushrod adjustment, don't forget a tad of free play in the cable ,that should sort it or identify the problem, regards BobH
