There does seem a shortage of suitable mounting points

Yep. Alex just needs to get an appropriate one welded on frame and pipes in conjunction with footrest finalisation.
Need a fixing including resilient mount close to the pipe to constrain it’s movements in all axis.

You sometimes see extra stinger/end can supports that vaguely resemble his tie bar arrangement but it’s not suitable for a main section support.

Alex does realise this but he wanted to get the pipes on to see what they look like lol  :D

And a trip to the engineers beckons not only for this frame but for the popsicle too...

Can you use a strap like I had on my 200, here is a photo so you know what I am talking about, it worked fine for me, may work for you, I used a couple of rubber lined P clips on the foot rest hangers to secure strap to frame, simples.

That would be a good short term option Tony!

Might even be the long term option!

The coils turned up today albeit with only one plug cap but no worries I have some new ones.  Snag #1...



Chipped and the NGK logo should be in white. It isn't. However I contacted the seller who was very happy to help out. In fact he checked all his new stock and to his surprise they are all like that. However he has some old stock that are fine so he's winging them out to me. Nice to see a genuine seller out there!

Snag #2...





With the coils on the tank won't fit! I have tried putting the coils all over the frame and not a chance. There are other options like under the seat so that might have to do. Means some bloody long HT leads lol. That or go for the modern look and try to find a different tank with a fair bit of space underneath...

What about in between and using the unused RAD mounts? Looks like there would be plenty of room there.

Good idea Peter but Dusty pointed out they are welded on wrong. So with a little 'persuasion' I bent them back and now they fir sung and the tank goes back on!





And then put on some new exhaust studs. The engine had 2 initially and 1 was bent lol.





Also thanks to Tony's suggestion I ordered 2 P clips for the exhausts...cheers for the tip matey!

Hope it works for you Alex, I used 2 end can straps for the exhaust also rubber lined, can't remember what they were from, just looked for the cheapest on ebay that fitted the diameter of the middle of pipe that had rubber lining, no problems with the heat melting the lining  :)

Good advice butt.

Ordered the P clips and they arrived today. Nice and simple and that will suffice for the moment.






And Dusty's old YPVS shock is ready to go on...

Not quite what I meant Alex, the Pclips (rubber lined ones) were only supposed to go around the footrest hanger, then rubber lined exhaust straps around the exhausts, that set up is going to push all the exhaust vibration through the bikes frame, I should have explained better.

The rubber lining to help stop any vibration and any damage to hanger bracket also allow some movement.

Oh I see what you mean now. No problems I can drill and mount them elsewhere if need be. For now they are just there to hold the exhausts on. I probably will get some proper mounts welded on when the frame goes off to the engineers.

Finally found a few spare minutes and cleaned up the stator. Turned out very well



But I am perplexed by the three mounting screws. Found a bolt with the correct thread and it screws in just fine...



Won't actually fit the stator holes though!



Any ideas?

Made a start on the Allspeeds today. Both are rusty but only the right hand one has any serious dents. A lot of sanding down and the left hand one got a coat of BBQ paint!
