i recently bought some pumper carbs which came with no air screws or springs!!!. does anyone know how long they should be?? (screws +springs) probably the same as non-pump vm28 but I'd like to be sure before ending up with wrong ones. cheers in advance.. m

give the guys at Allens performance a ring to be sure. They will also have the parts you need.

thanks Warren, I'll check the link, i have possibly sourced some already, but the seller has various lengths. I'm aiming to test run the carbs then possibly fit keyster kits if required. cheers m

Mark,
I've got a set of 28mm pumpers from a 1000. I can check them and let you know if you'd like?

yes please nigel the top of the thread to the tip and the spring length would be much appreciated. thank you very large!! mark

The ones fitted seem to be quite a way down the passage way so I'm wondering of not original or correct. However, they came off a running bike which had just been setup on the dyno...
24mm Total length
19mm tip to bottom of thread

I forget to measure thew spring length, but will do.

Hope this helps

that's great nigel, super rapid too..i hope you counted the turns on yours? cheers matey. m

No worries, I'll need top remember to measure the spring length too..

no rush mate,re springs; just whenever, if you can be bothered, screws are hopefully not an issue now thanks to your help.. cheers mark.
