I would get a few from 126 to 132 to try.I probaly could have got away with a 130, as I was running a tad rich.But I would rather run a little rich than lean.

Re: shut off at high speeds

Running a little rich would also help cool the engine. Sounds like the 132 as suggested might be a good idea.

Yes.I would start with smallest jet and work from there.As your air box and filter are stock you probably only need to go up a couple of numbers from stock.Take your time and keep notes of what jets you have changed.That way you can always look at your notes to go back one step if need be.

Re: shut off at high speeds

i got a 127.5 and the bike didnt change to much still runs well but then dies . my mech friend told me that my lack of the vacuum tube on my petcock should be a big deal but when i told him about how it was dying with the 120 and 127.5 he told me to check the flow from my petcock and he was right it flowed well for a 20 seconds and just drip drip dripped . i guess ill wait for my new petcock to arrive

Re: shut off at high speeds

You need your new petcock to hook up your vacuum so you can get fuel flow back to normal.The 127.5 main jet should be large enough to keep your bike from running lean.Good luck.Keep us posted with the results.

Re: shut off at high speeds

Damit - this was one of the treads i might have been able to contribute to and it's already solved.
Well i'm glad you found the problem but i haven't heard of any interchangeable gz petcocks but on the other hand, i never went looking for one. If there is i'd say the dimensions would be the only issue. Also i don't know this but they might be interchangeable with the GN models which are far more common over here - just a thought - the others will be able to confirm/negate this.

Re: shut off at high speeds
