thinking out loud....ive been searching on ebay for fazer bits,mainly carbs and coils,although you cant gaurentee any of the parts i still think a cheap set of carbs/coils will help in problem solving,and you can always sell them on afterwards...iam watching a few ads and might make a bid if its cheap.....would`nt want to keep the parts on my bike,purly for problem solving.......

My cam chain's not rattling at all but on the advice of this thread, and prevention being better than the cure, I gave mine a right good thrapping on the way home tonight!

nice one

if you can get the picture on here ian sure we can give you the answer

for sale................2000 fazer. 50 owners, lots of extras, runs like a swiss watch ( in me dreams ) will take 38p and a bottle ov tizer !!

great minds....you beat me to it

parts might be here friday,if they are i can have the carbs back saturday morning...so i have a bit of thinking time...
  i must point out at this stage that i think i`ve spent more time on this problem than ADE THE BLADE.so i might have an unfair advantage,but he has checked things that i hav`nt.....anyone know the odds

still waiting for parts

yes.......the two that are missing,where on the engine are they ?

put the old filter in and see...wont cost anything....i have k + ns on my suzuki x7, jetting has to be spot on to get the best from them.

i can understand you taking the carbs off 4 times...it does sound like a carb problem.are the diaphrams ok ? you mention k+n filters have they been on long, are the jet sizes correct,do you still have the origanal filter that you could refit to see if it makes a difference

the brass fitting is like a top hat and is a push fit into the bottom of the carb above the main jet,if you remove the main jet and emulsion tube and look down the hole you will see it,acts as a guide,will see if i can find out its proper name.....going to order the part today...............never used a dynojet kit before so not sure what parts are included.

took the carbs up to be sonic cleaned at lunch time,got a call from pete the mechanic saying he did`nt think the carbs needed the sonic clean as they were clean already,he did however notice a small brass needle guide was missing on no 1 carb i must have dislodged it when i cleaned them out myself it sits in the bottom half of the carb acting as a guide for the needle,without it petrol is just going to flood in....pete described it as pi**ing in a bucket...good description....i could have solved the stutter by cleaning the carbs but created another by loosing the guide,the part is available from yam at £25 +vat ....i`ve had a look on the garage floor but cant find it,bit like needle in a haystack ,i`ll get pete to order it in the morning might get here by friday..........

been thinking about this since you posted,are you sure the new filter was seated correctly ?

22mm.......or 7/8 in old money
