Re: What is normal??

Hi Adrie and thanks for your input If I understand your suggested test method correctly, the piston position would leave the inlet tract open to the carburettor and therefore to atmosphere, also connecting each cylinder to the other so could not work. Maybe I have misunderstood you? Although my firs...

Re: What is normal??

Hi Roger The concept of being able to test the crankcase seals has intrigued me for a while and I did knock up some sort of kit but as it was only capable of testing the two sides together and not the centre seal it was all a bit pointless really, though it would pick up porous doors or worn end sea...

Re: What is normal??

Hi Trevor As Brian rightly says, electronic ignition will not solve anything, a correctly set up CB ignition is quite capable of the job, despite the Joseph Lucas components! Have you done a compression test or tried starting the engine and then pulling off each plug lead in turn to establish if onl...

Re: engine no's

Don't you think that the difference in performance between an Arrow and a Sports Arrow is so minimal that it's hardly worth the effort? Do we even believe the originally claimed BHP increase? If you want to keep up with the traffic something more radical may be needed. Any other thoughts/recommendat...

Re: electric start leaders

That is useful information and your link for regulators was exactly what I was looking for, thank you. Swapping over of the brush units on my dynastart may not be straightforward, it seems not to be in its original configuration as you may be able to see in the photo of what I am working with. Regar...

Re: electric start leaders

Hi Peter The engineering/machining should not be a problem, I'm half way through making the parts for a TLS at the moment and the electric start is more of a long term project (for when I can no longer use the kick start)I'm keen to learn from the experience of the others, like yourself, who have al...

Re: electric start leaders

Hi Peter and thanks for the reply I would be grateful for advice you can give to save me reinventing the wheel. Is there any more to do for the rotation than match the bikes polarity to the rotation needed? I didn't get a regulator with it and assumed there would be an electronic equivalent availabl...

Re: electric start leaders

Hi Peter

I have picked up a Suzuki gt185 dynastart with the intention of going electric. Could you advise me if I need a particular regulator for it?
