A7 & A10 Engine / Re: Engine failure troubleshooting

Righto, I just tried starting the bike before reading all these comments and the damn thing caught fire! Looked like it started at the carburettor. Fortunately it was a very small fire and I had a fire extinguisher within arms length of me, so it was out within a few seconds.
Just how I like start to the morning *lol*

I've cleaned it up now and I've just removed the carb. I'll drain the tank and remove the petrol taps. I also noticed that air is escaping from the timing side cover via one of the screws when I kick it over...not sure if it is note worthy how the bike is? I'll check back on the forum regularly throughout the day to keep you updated and see how things progress!

Also to answer Greybeard, Yep the magneto has been serviced by APL magnetos a few months ago. I'd be hugely disappointed if the mag is playing up already.

Thanks for the explanation chaps. It would seem that a flat mushroom would do the same job except for the  slight movement on the spring studs.

like greybeard says, my recall (from reading other threads, not real life is) is there were two types of 6 spring. The earlier plunger semi unit 6 spring was well regarded but the later pressed steel centre S/A version is not much liked.  So maybe check which type you have?

The 4 spring on my a10 is reliable whereas the later pressed tin 6 spring on my b33 is wobbly and unpleasant. I'd love a pearson / belt drive setup but pockets aren't that deep.

  G'day Dutch .  That is the side a proper bearing would be an advantage. Not much room though *work*

I'll put my money on Klaus's suggestion.

try both taps turned on - might show or eliminate something

..... Also the push rod is allowed to turn with the mainshaft by the bearing ball on the operating arm...........

 In addition to ironheads comment who jumped in while I was tapping;
 Exactly- that's a small area to carry such a load, especially if sitting/standing still in gear. The tophat/mushroom bearing alleviates the load and allows the clutch to spin without necessarily spinning the pushrod (fwiw, the ball in my activating arm has a flat worn on it so I match it up with the pushrod so there's more surface area to take the load- works for me *whistle*).
 Gutzzis also have a radial roller bearing behind the actuating arm (not a standard size though so have to go 'special' *rant*)

I plan to ride, but so busy that I've not taken the time to set up a "World Wide Ride Team" for forum members. As GB has noted, the interest on the forum is basically pathetic and apathetic. I hate to think about how many of our 1107 members have been diagnosed with prostate cancer since we started talking-up the DGR. Anyway, if I get a chance, I might set up the team just to keep the flag flying, but not sure right now.

In fairness, I reckon a lot of members are not reading the non-technical sections of this forum. So, are not aware of the plea to join the DGR. Many members may be DGRing without mentioning it here.

No your not thick, the only relative motion will be a slight bit as pressure is first applied to the pushrod ( spinning shaft , stationary ball in the r/h adjuster) I have found ( after making a few) that the main advantage of the alloy plate is the fact it is a snug fit over the clutch centre thereby centralizing it, whereas the standard pressure plate
sits on the first plain plate in the middle & only has the spring studs to centralize it.

ps    if the alloy plate is not a snug fit over the centre it is no better than the original.
Hope this makes sense.
