You'll have to look at that clutch and clutch pushrods.I assume that with the cable disconnected from the clutch arm it is nice and loose. Was there some free play before the event? It's only a tiny clutch compared to my BMW so should not be heavy.

still a noisy clutch/primary drive

Well that's where I think it comes from. Only noticeable when at low revs,say in 6th or 5th at a slow speed,and not on accelleration or normal speeds there is a distinct knock or hammering sound at I think half engine speed. I am convinced it comes from the left side. I have had the whole engine apa...

Having written a reply I think it didn't submit..... An easy engine to work on (not much help if you have not) Some special tools may be needed, though you can work around most of it.Mostly involved in holding parts whilst undoing retaining nuts. Disconnect the battery first. When refitting the eart...

Sometimes I get a bit of a tingle in my fingers even on a K75S which is about as smooth as you can get. I think it may just be an age thing.Perhaps this is the reason I cannot get my hand into my wallet at the pub. I don't find my 350 overly vibratory in any rev range and just use thin rubber grips....

Can't think of much apart from just putting it all back nicely. I hope you find a broken spring or something tangible as the cause, I don't like mysteries.Of course check the bearings if you wish.( I am more used to shimming end float in BMW gearboxes after they have wiped out a bearing but in the M...

Did you swap HT and spark plugs? Something must be failing with increasing temperature.

At least check what resistance you have on the green wire coming from the stator. Shouldn't affect the lights if the ignition coil is weak but if it is less than around 186 ish ohms you may have trouble.Does it start easily? What are the earth connections like? I lost my front left indicator yesterd...

Hi and congrats on the bike.I'd probably shake it down over the summer (if it continues) and get ready for the restore in the salty season. Mine came with Dunlops of some sort. They seem to work OK, I have had no issues. I use BT45's on my other bikes (old-ish Beemers)with no complaints. I would thi...

Thanks for that. I already have a hawker battery,it has never let me down. I connect to a trickle charger in winter now and again but it has not been down on charge,so at least part of my generator is working.And soon the other part will too,I hope once the ignition coil is refurbished. I will accep...

starter motor

Forcing myself into the garage this evening rather than basking in the balmy summer sun watching sparrows searching for water etc I decided it's time to remove and renovate the stator,which had only 186ohms on the green wire last time I checked. Having a starter motor which sort of works at least wh...

I have ordered some neodymium magnets to play around with. Well it beats all this sunbathing....
Each is supposed to be capable of lifting 13kg so I expect to find the postman stuck to my letterbox on Monday. I will be wary of passing over manhole covers.

Magnetic oil filtration

Has anyone tried or considered using magnetic oil filtration? I know of this application in bikes with canister filters. I guess the only options would be fitting a rare earth magnet to the filter cover, or the drain plug. Not sure if the presence of such a device within "earshot" of the g...

You need to check again that the ignition timing is about right static. Is fuel flowing correctly? Is it Fresh fuel? Was the cambelt touched? Recheck all the marks associated with timing and valve clearances. Are the carbs really set up correctly? Assume you have made a mistake.My 350 would not star...

I have replaced the indicators on my later model with mini-indicators. Much lighter. I had to have a rear mounting lug re-welded first.I think it had failed due to stress looking at the broken surface of the metal.Rather horrid looking metal at that. The flashing rate was a bit quick, but I swapped ...
