Quick question I've got a 1275 with hiff carb and full manifold exhaust system and k&n air filter , which needle should be used ,
Suposed to have a updated head but can't be sure also many a cam but again unsure of this

[ukcooper]

is it a hif44 or a hif38

[mattyglover16]

If it's standard it should be a HIF38 but double check

Hi

There should be a tag on the carburettor with some letters first then some numbers,

HIF 38 are normally starting with MAC, HIF44 are normally starting FZX, If it is a MAC it will have 5 Numbers  or HIF44  and has  FZX, it will be 4 numbers.

Failing that if you do not know if it is either, you will have to take it off and measure the inlet hole..

After this I can or maybe able to give you a needle size but rolling roads are the best way forward, trouble is they charge an arm and a leg and you get to see them rev the ******* out of your engine (painful) and you have to pay them to do this as well !!!!!!!!
