But what are the revs for a certain speed in top gear?

But IS THERE an advance and retard??? My manual mentions it for the 125 electric start models with generator but not the standard CT3 with magneto.

Is there an advance mechanism? No mention of it in my manual when timing it?

But at what revs?

Did you ever resolve the problem???? Just wondered what it was.

Just got the CT3 through an MOT, so can do some road testing. Couple of things.....I believe I have put it back to standard gearing (45 teeth rear: 16 teeth front), but at 6000 revs in top gear the speedo reads 40 mph. 5000 revs is about 30 mph. Is that normal? Also, it has just had a rebore, so I don't want to push it too hard, but it really struggles to go above 5000 rpm. I had introduced an air filter, but it is the same with or without. Checked the timing, and its as close as I can get it. Any suggestions from all you experts out there?

Does the CT3 have an advance/retard on the points/timing??? Only ask as i thought they didn't and I'm about to check my timing. (And mine just passed it's MOT for the first time today )

Venhill Engineering make cables to order.......http://www.venhill.co.uk/ They are making some custom cables for me at the moment......their cables are sold worldwide.

Still not managed to sort it....any suggestions?

Thanks for that...although doesn't sound easy. I'll give it a go, but measuring 1.8mm sounds a bit difficult. How critical is it?

Is there another way of checking the timing besides buying a special tol and measuring when the piston is 1.8mm before top dead centre? And is there a way to adjust it apart from adjusting the point gap size?

So 'Up Yours', you're saying your bike does this too?

Just put my CT3 back together after a reasonablly comprehensive refurb, and am wondering if I have an earthing problem? The bike starts and works fine and all the electrics work OK..........however, when I put the indicators on the neutral light dims in time with the flashers...likewise if I put the brake light on etc....... thats with the engine running or not. I have tried earthing the battery out to other points on the bike, but no difference. Is it an earthing problem or could it be something else? Or is this normal?

I've been restoring a 1973 CT3 and have found its often cheaper to buy parts on the american ebay site, even with the occassional import duty. Parts are alot more common there too.
