Dyna-S ignition system (now cam end float thread)

Bryanj:
All I can say is the Transfleet is fine and when i asked Silkolene now Fuchs they told me the Titan was the replacement, nowhere does it say it is synthetic so it should be OK. You can still get Tesco Mineral oil from petrol station forecourts but not the stores for some reason

Thanks Bryan will give it a go. It's had a hone and new rings so will use use the 10w-40 oil thats in at the moment for a couple of hundred miles. I shall report back in Spring if this oil makes the cam knock go away.

royhall:
Just a quick update. The oil change did not make a scrap of difference to the cam knock situation. Going to whip the cam cover off and have a little look.

McCabe-Thiele (Ted):
That oil in the  link is listed as Mineral - I used Fuchs Titan Unimax UltraMC 10W/40 in our old Jeep - trouble is its synthetic so could cause clutch issues.

Only thing I have used that has ever quitened an engine noise on an engine (Alfa Guiletta Sprint GT back in the 1960's) is Molybdenum Disuphide (Molyslip) it makes the oil more sticky - looks horid as it is black. It takes a good 15 minutes to circulate & coat everywhere  - in reality hides the problem so I doubt that would not suit you Roy.

royhall:
The Fuchs Titan oil is fine with the clutch. I would be very reluctant to use a Molyslip type oil as that will cause clutch slip, if it was a dry clutch it would be going in right now. The cam end float on Suzuki GS is a very common problem and causes no engine damage long term, I was just trying to tone it down a bit.

I really don't like the idea of the so called repair in the above post. The reason the cap is stepped back from the cam is to allow the oil flow to lubricate the cam lobes as there are no drillings to do that job. On the "fix" you are making the end float bearing face continuous which then becomes pressure lubricated like a shell bearing and prevents end float, but it will starve the cam lobes of oil and eventually cause engine damage. I will have another look and check the cam chain pulley sideways action whilst I'm in there.

Shame really as it's the only problem on the bike. The thing is reliable, starts at the touch of the button, runs well and goes like stink, and also sounds awesome with the Delkevic 4 into 1.
