4L0 carb main nozzle replacement

[yamanastic]

I'm thinking of replacing the carb main nozzle and needles in my carbs, so looking for a bit of advice,
1 is this a good idea
2 if it is a good idea how do I remove the main nozzles from the carbs
3 are the main nozzles from yambits any good or am I better using genuine nozzles
4 as the needles are no longer available what make of needle is good to use

Like everything they do wear, so replacing with new is a good starting point. Yambits is a big NO, ring Allensperformance for gen parts - all you need is the jet needle and needle jet numbers for your type of carbs - approx £45 posted (both carbs).
Loosen of main jet a few threads and tap lightly with a small hammer to release needle jet. Remove main jet and needle jet pushes up through the top of the carb - slides removed.
If renewing and very tight a thin punch will help tap them all the way out.

Thanks for the reply and advice, I know the needle is a 5k1 do you know what the number for the main nozzle would be?

From engine numbers 4LO 100101 onwards:-
Jet Needle - 5K1
Needle Jet - P-2 (345)
