  1. What measurements for magnum swinging arm do you need? Here are some rough tape measure dimensions for now

  2. Tr1umph had a spate of problems with brand new starter clutches grenading. It was caused by the engine spinning over too slow when starting and therefore causing the ignition to be advanced, and the engine to kick back. The problem was with the igniter not the starter clutch itself. Replaced under warranty with modified part (sometimes). Don't know how you would reliably check aftermarket ignitions to see if they retard ignition effectively at cranking speed though.

  3. I suppose it depends what you are used to, but I don't find them too cramped (I'm a 5' 8'' short ectomorph with a moderate beer belly, dodgy knees and hip). There is a decent oldskool reach to bars, and footpegs are a bit close but don't give me immediate cramp like a Katana. Closest comparison for riding position is  a Jota I would say. A modern(ish) 750 sports bike feels like it was designed by Frankie Dettori compared to the Magnum. Keep posting the pics.

  4. Started adding a spoonfull of two stroke oil to last fill up of petrol if bike is going to be stored for a while after noticing two strokes don't seem to suffer as badly from gummed up carbs. Run for a few miles before storing to get mixture coating everything. Not done a side by side test. If you buy the right oil it makes it smells good as a bonus.
