Plug size

[mickeyb]

Any1 know what size of plug i should be using on a Muggy 200 classic with a 30mil Dellorto?

If by size you mean what Temp range. It would depend on how you ride it, if its being run up and down the motorway all the time i would use a denso W27es, but for normal rideing a denso W24es would be my choice, just my opinion though.

Nippon Denso spark plugs. There have been a spate of dodgy NGks. Denso's are far superior.
