Wonder if anyone can help?

A while back I got a set of 2R8 carbs in good condition and cheap.

I want to convert them to something that might work well on a YPVS so I have a choice of carbs to test on the dyno.

I have bought some of the P type atomisers for an RD400.

Can't seem to find for definite what needle goes with these.

2R8 are RD250 E/F carbs, and they are slightly different to the 2R9 carbs which are the RD400 E/F carbs, in respect of the P needle Jet, I am assumng you mean the one which is used in the Dale A mod?, if so if you look up the Dale A mod on the net it will tell you which needle you need. I have a set somewhere, if I get chance I'll dig them out and let you know what they should be

Piles, they remind me of a family of rasberries looking over a grave....

Thanks muttsnuts, but its not the Dale A mod.

I got P type atomisers from here:

cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=251329760887

Just want matching needles for a 400E I think, and have seen several different references.
