I think it should be ok. Sean other people put them there with no majors. Will keep a close eye on it. So close now. Back to the shed after dinner to weld some more stuff. Would have been a little closer if not for a case of chronic (can't see the bit you just made and put somewhere in the fucken mess that is the garage - eyetis).

Mounted my CDI on the rail above the motor on the FXR frame, then had issues where the bike would get harder to start through out the day and running rough as if getting to hot. Not sure if it was the CDI that caused the issues but after moving it to the rear of the bike and tiding some other stuff hasnt been a problem.

Cool good to know. Will keep an eye on it.

More progress. Finished welding up the subframe today. Quite happy with it. Not quite ready for a blat up the road but almost.

Cheers Scott. I am so into the whole process I am now itching to start my next bike. Was thinking of you when I welded up the sub-fame and then went to bolt it up and found it was rather a different shape than what I started with. Was still plenty hot so a couple of knocks with the hammer and letting it cool all bolted up. I can only imagine the jig you must have to build the frames. Total respect.

Grumph asked why the fellow in the NWS pic looked bonkers. Well he is, in a good way.
I will post why later.

I think there is a pic of one of the crazy frame's still on the jig on his tread somewhere as well. or maybe not

The plan I have is to build around the old FXR frame then cut away the old bits. Looks like it should be ok. I will build a real basic jig for that job. After talking to Mr water cutter I am also now looking at using some late model 600 forks. Water cutting the triple clamps will be cheap and easy. He said just make the holes .5 under then mill to size later. Will have to check the weight of a gsxr stanchion to see if it will be worth it.

If i may suggest if you were making clamps make them adjustable for offset. That way you can adjust the trail independent of the rake also most of the race bike clamps are real deep on the lower yoke. A built in bracket on the lower yoke for a steering damper could be fun (like an RS125)

thrown in a ROb North clamp as they are neat i think the Works BSA MX ti bikes had beatiful fabricted yokes from round tube that were far lighter than any exotic Mag alloy

I don't know why more people don't fabricate triple clamps - the last pre 72 I built I fabricated the top clamp from machined bosses and thick wall open channel which I had bandsawed out of rectangular tube...TIG it up on a simple jig and bobs yer unkie..
Came out quite light and very stiff - without any real attempt at lightness too.

I suppose the lure of the magic acronym C.A.D....and shiny billet is too much to resist for some people.

I use CAD all the time "Cartoon aided design" more of a thought process, cant download an app for it, also use chalk to draw in the floor "Chalk aided draughting"
