Title: Where to source jets for carbs for CB500 Four K2
Post by: Nashfly on March 26, 2024, 10:09:16 AM

Hi all,

Looking for #110 main jets and #42 slow running for my Honda CB500 Four K2 (I reckon 4 of each will suffice!)

I'm based in South West Wales UK

Any suggestions as a good source - or anyone on here wanting to sell....?

Thanks in advance for any assistance

NRP carbs

Those are a big increase on standard for the mains

Hi John

Thanks for the speedy reply, much appreciated

Standard are 100 & 40

From spending hours researching on this forum, I concluded that with pod filters and straight through exhaust that would be a good starting point for my build  (a bit richer than standard.....)

Happy to be corrected

Didn't realise you were running non standard pods and exhaust


As others will comment, short pods don't work well,


The intake length is designed to work with a plenum chamber/airbox

It's to do with the pulses of the airstream

Good luck
