Anyone know of or use a place that sell's Keihin carb jets? After a couple of pilot jets for a GPZ305 that's in for work. One company I tried is closed until 4th Jan because of the Christmas break! Lazy sods!
Part number.. From what I can gather, it's N424-25, it's got '35' stamped on it, is 15mm long and I need two of um.

Wemoto were very helpful last time I used them, as were GPZ Zone. I would imagine the 900's jet #35 will be the same as the 305's?

If it's a CVK carb, then there's every chance..
Looks like this

Yep. Same same. 900 is a CVK34
There's a pic of the jet on that GPZ Zone page.
https://www.z-power.co.uk are the only other ones I can bring to mind for Kwack parts in a hurry, although I havent used them for years

Which reminds me I was meant to strip the 900's bank of carbs down in summer.. and derust the tank, change the tank filter and all sorts of shite like that.
Bollocks. When did that cold weather turn up? It was summer last time I looked?!

I've found
NRP Carbs very helpful in the past - known as a supplier of diaphragms but they do other spares as well.

Try a an off-road bike dealer - most Jap crossers use Kiehin carbs as standard and most racers and their Mechanics (usually their Dads) play around with jetting all the time - often with varying amounts of success/skill
Racing is life - anything before or after is just waiting.

This is something I've noticed when searching for parts in the past. The off-road boys dunarf do some funky stuff..lol.. Have found a place in Llandrindod Wells that do size 40, and a place in Manchester which does the size 35 called NRP carbs. Since BG has posted with a recommendation, I shall be using them. They're also the cheapest..lol..
Cheers for the reply s all!
