Yes I've seen that build, might be a bit tricky with this one O.oIMG_20231026_200729.thumb.jpg.d18d013bc7abb8c3dd550a29c2fede85.jpg IMG_20231026_200714.thumb.jpg.a12a63768d7ea922c9140716150103b1.jpg

If you start cutting that frame about don't post any pictures of it on the internet. Chicken central would be surrounded by purists with pitch forks and torches. xD

 Do you know how they got a spacer in for the lock-up clutch, perhaps they moved the engine a bit in the frame ? 

As I understand it "its well known that Bob was stubborn" so it was done with a bit of butchery and adjusting the engine position slightly it only need a few mm of clearance as if you look at a close up pic the frame / rear mount slightly encroached over the case ...

Bob supplied a longer stiffer arm with drag slots for the revised lowered version of the bike and i think he tried a set of raked yokes in it as well 

Apparently when he ordered the beam frame it was built with clearance for the lockup spacer  "I bet that was a very abuse laden conversation"  but that said he did a lot to promote Spondon  :tu

on a coax its a huge problem to overcome as the cover / engine is behind the arm pivot ... :stop:.   so best not to go there

A m8 with a mag4, similar problem - ended up cutting the offending tube out and remaking it with space!

Yes Jimbo with the Yellow Harris turbo had to have his frame modified for the same reason I think there's a pic on here :tu

pics are here 

 unfortunately some the pics are photo bucket overlayed since he originally posted but still viewable and there are clear ones on page 3
