Usually all you need to replace are the needle valves and possibly the float bowl O-rings. Most of the stuff in the kit you won't need and are better off not using, like the pilot screws.

Well worth changing the pilot jets to #15 while you have the carbs apart, which is the size used in 5jj carbs.

Make sure the tank is clean, and check the screen on the petcock.

Thanks for helping.
Just one other question I have now checked and all kits etc showing #15 and #130 pilot jets but in my manual and on the jets in bike show #17. 5 and #130 which is for 1998-1999 model and the 2000 onwards should be #15.
My bike is 1998 model so now confused.
Have tried quite a few suppliers but seem to get same answer they don't know and it should be #15 for my bike??? 🤔

The US bikes had #15 pilots but the UK spec bikes came with 17.5. I fitted 15's to my bike after someone here recommended them, and was surprised how much better the bike ran in the low-midrange. Definitely worth doing.

It's also worth checking out an Ivan's Jet kit. I have one of those fitted in my R1 along with #15 pilot jets and it runs awesome!!

Or you can raise the needles. I found a whole groove was too much, so raised them half a groove with some thin, 3 mm washers.

But the Ivan's kit is the best way to go
