Topic: Carburettor Rejetting for 400F - Oversize Jet Suppliers?

[robnobrakes]

The main jets to my carbs will need to be increased as I'll be running Ramair foam filters, no airbox and free flow 4 into 1 race exhaust (Yoshi?) system.  I have ordered size 80 main jets from David Silver, who cannot supply any larger.  Are there any other suppliers who can supply 85's if the 80's turn out to be too small?

Jetsrus.com has jets for you all the way up to #153

Thanks chaps.

They both list the correct jet type, but there is a big jump from 80 to 98.  I'm assuming 98 will be too big for my set-up.

I suspect 98s would be rather huge. Have you tried Allens ? http://www.allensperformance.co.uk/

Siriusoninc has jet packs from 75-95 and 100-120 (or thereabouts).
