poor idle and TPS

[MC680x0]

I didnt buy a OEM air filter, I just cleaned it as above : http://foc-u.co.uk/index.php/topic,14567...#msg164707  so ---- the only thing that's not right is that the posts are not being read  :lol

I just cleaned the air filter alas this did not sort the problem so I've ordered a K&N on good advice from you+others ; however, my bike is running lean so because I've ordered a K&N which will make it run even leaner, I have also ordered a carb pilot screw adjuster as I've just burnt my freckin fingers trying to piss around under the carbs with an operating temp heated bike  :evil . I wanted to check/set the idle mixture on each carb as the plugs colour indicate a lean mixture certainly in #3 and to a lesser degree on #4 - I've raised another thread about pilot screw adjustment in case anyone searches for pilot screw/idle mixture http://foc-u.co.uk/index.php/topic,14571.0.html  I could have easily included it here though but I'm fairly confident I wont do the right thing and someone would complain that the topic is getting confusing, or I'm mixing up subjects, or I should split the thread - you cant win !

"....By the way, I have since ordered a YAM OEM air filter from wemoto so we shall see...."


I think i read that quite properly, and i can't really see that sentence meaning too much else, but if i did read that incorrectly then please enlighten me as to where i went wrong?  :look

Rather than getting pissy I'll answer the original post by saying I think that the idle fluctuation you mentioned sounds fine to me considering the age of the bike.  I'd say thats roughly what mine is like and runs perfectly fine.

Just started my bike after sitting 5 weeks idle (I'm off sick) and let it tickover for about 8 mins to get the juices flowing, and after about 4mins the needle was virtually static around the 1150rpm mark, maybe 1mm play in it.
Bike's same year as both of yours but mine's on 44K miles, compared to the OP's 17K.
I'm not getting "pissy" about anything, just informing you of what I just saw, before I take it up for an MOT and a new front tyre.

Cheers darrsi... You certainly got me thinking now cos by comparison of bikes , mine should idle better. I'm going to drop this k&n in then set/ adjust the pilot screws then resync carbs.

BTW, I received my previous statement about not reading posts,... I meant to say I had bought a K&N not b an OEM, for sidetracked and left the typing and cane back to it. So me owes you an apolz on that one  :o

[darrsi]

No worries.
