which jet kit or fzs 600 fazer 2000

[Gnasher]

Cheers .it has nowt BELOW 4 k . i have been running it on Profi fuel-max additive FOR OVER 300 miles . Went out this morning for a couple of hours didnt go above  3k as i think the pilot jet works to around 3/4k ?? Seems slightly better . But still has a fluff when you hold it at 3k . Maybe a good strip and clean will do the job . Cheers for the helpful info . I thought the fzs ran on the weak side that is why i was going to rejet . If they run rich as you say should be ok .I have a Zaddoz exhaust sounds cracking but took it off as i thought it was suited to the bike flat below 3k but the Scorpian isnt any better . So after clean out will put it back on .

Mate your original statement was

Going out this morning with a rev ceiling of 4 thou.

 

Your latest info is reverse, in which case yes this will more than likely be the pilot jets.    I've never heard of Zaddoz, most cans work very well, one of the best IMHO is Quill.
