Doesn't tyga make billet triples for the NC35?

It shouldn't be hard for them to fit an NC30 stem instead.

They do goulime has a set, as it turns out a 30 stem won't work as the fork tapers in dia so you'd not get the clip on fitted once you had the forks through the top clamp enough to allow for the geometry to remain unchanged, got to be done with a 35 stem and spacer.

Ok,

I need some pictures of a set of NC30 yokes please, in particular the lockstops and the ignition barrel holder, I would take pictures of mine but I am working away from home this week and I also do not have the ignition holder on my yokes as it has previously been cut off.

If anybody has some on a bench or off in a box that they could photobomb that would be great.
If you can email me the pics that would be perfect.

Do you want a 35 frame and swingarm to save you the hassle mate?

I need pictures of original NC30 yokes so the machinist can work out how to best machine the yokes and also to highlight anything that may cause a problem in the machining process.

Tony, I'd still need Yokes and the only reason i wanted to look at the option of getting some machined up is as i want a new part thats stronger and lighter than a set of original nc35 yokes. SES do a set of NC35 billet yokes for £350 then plus the spacer etc.

Just thought i'd see what a couple sets of yokes turned up would cost us. I wont be doing the conversion till winter so no mega rush, and the price may come back at a decent price, last set of 35 yokes i saw they wanted £150 plus shipping for them!!

Ok don't panic about the pics managed to use google images and he has what he needs.

However if anybody can let me know the length of the 30 forks from spindle to top (extended) then he can do a rough cad layout to check 20mm for the spacer is enough and play about with other heights spacer to see what effect it has. The 675 forks are longer then the NC30 so he is going to try and get it so that these will be specific yokes for the 675 rather than a set of NC35 yokes that you have to run the forks pushed right through, as this will give greater adjustability with regards ride height etc.

He has a set of 675 forks with him at the minute as he is doing some yokes for a street fighter project that is going to use 675 forks so he has all the measurements he needs for them.

I will measure mine when I get home but i'd like a check measure if possible.

Thanks

Pretty sure when I put them side to side the 675 were the same length as the rvf forks

Funny job - i am just about to start fitting some 675 forks to my RVf race bike. I would be very very very grateful if someone could give me the dims of the wheel spacers, or if anyone is able to get some made i would be more than happy to pay.
Cheers
