Sorry about the delay guys, I've been incomunicado at Blackwood.
Murray, I might have a spare Super Pioneer motor which Alron used in their bikes, the head cutaway for the fins takes a stock SP pipe which Ron Lyon used too. I'm dead keen to get your SWM motor but am I fiddling a bit too much with the history of the bike? The factory did install the T'n'T motor but the original was a genuine SWM. Decisions, decisions....
Now, I admit to being a bit keen with the tinsnips but the devil in me (and the memory of Norm Watts' bike and Gunny's bike) made me go the GP cutout PK used in Gary Jones' bike which hauled.
I'm yet to check out the flywheel weights but want to leave the pipe stock for the appearance.
Thanks for all the helpfull suggestions guys, I know I'll get it right soon.
I had a ball at the Kenda Rally on it. After the all the dumb incomprehension of 'What is it?' I had it sound tested by the DSE at 93.8db @ 5000 rpm, under the latest FIM/MA/DSE 94 level. Cool. Revised suspension worked a treat and while I took a hammering from the rough, rocky and rutted course (fast too) only my hands were sore from clutch and front brake pull. Surprised a lot of riders on the downhills and caught all the guys who blasted past me on the roads in the tighter stuff; sweet. 158 ks and I only lost 2 bolts, one made the front KTM guard wave madly but it didn't break.
