Hi . I have a bit of a problem with her . She pops farts and stutters below around 4 thou . Trying this stuff you put in the tank . Going out this morning with a rev ceiling of 4 thou . As i think the pilot jets are dirty so will keep it under 4 as this is where the pilot jet works I THINK ??? Not sure if fuel is past through the jet at higher rpm ??? Looks more likely carb strip . SO while they are to bits would be a good time to fit a jet kit as i have KN in stock air box and an open pipe Scorpian full stainless system with baffles out so would think running quiet weak ??? .Not sure which way to go Dynojet OR ivans the later cant find UK supplier . Anyone know who sells ivans jet kits ???? dynojet plenty available .Or are there other alternatives to these . Also will fit stainless allen screws . Get my stainless from a local guy STIG at Darlington who is very reasonable . Any help/info appreciated .
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 .

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.
he's gone for a ride keeping the revs under 4k to force the additive through the pilot jets.
OP, I wouldn't bother with additives myself, it may even contribute to the running issues. strip and clean the carbs and jets with carb cleaner, and go for a ride with fresh fuel, without adding your own additives.
Mate your original statement was QuoteGoing out this morning with a rev ceiling of 4 thou. Well yeah taken on it's own that would imply something else but for some reason only known to yourself Gnasher, you've chosen to leave out the bit that immediately followed it...Quote from: davidh on 25 June 2020, 05:32:04 am As i think the pilot jets are dirty so will keep it under 4 as this is where the pilot jet works I THINK ??? I've had this issue too and a fuel additive did nowt for me either. Ultrasonic carb cleaning did the trick
