@red98, have you thought of contacting Gareth Gates, he had a bad stutter but seems to have sorted his out okay  :lol

I will try the filter back in at the weekend and let you know how I get on.

I just had a thought though. A friend checked the bike out for me a few weeks ago and commented that 1 cylinder was running hotter than the others (down pipe was noticeably hotter from startup). The other three cylinders were running a little rich(petrol smell) I will check the plugs at the weekend to to confirm this. Anyway a lean mixture would get even leaner with a new filter, so I wonder if one cylinder is too lean at high rpm and is causing the stuttering?
 
 
 assume a carb balance may be the simple answer as in the long term, I cant simply stick the old, clogged filter back in, to force the bike to run rich.


Does this sound plausible though??

 
ummmmmm .....not sure about that  ;) ......start by swaping the filter...i dont think thats the problem but once swaped you can forget about it  :) .....balancing the carbs is always a good thing  :D  do you know when it was last done ?  :)


.....well, checked the plugs and ht leads, bit of wd40 applied. Left New air filter in place as I noticed the rubber cover over the airfilter casing had snagged over the air intake, possibly restricting the airflow. Assuming the engine needs a huge "gulp" of air when the throttle opens, this may have been an issue. Will test ride before putting old filter back in.


Bike fired up fine, needed a bit of choke, normally doesnt! Idling ok, just a tiny bit lumpy...


Will post back later!!


Well I put the original filter back in and the bike is now fine, stutter gone!  :lol  Checked the two filters while out and the new one is a tiny bit smaller. Noticed the box it cam in had 98/99 for the year. Wonder in the filter is different on the 2000 model then????


Anyway, bike running nicely, carbs do need checking for balance, but power all back now!!


 :D

Was the new filter a Hi-Flo one by any chance?

Was an aftermarket one, apparently standard, but who knows with pattern parts. The original filter had a gauze/mesh cover, the replacement had a metal sleave round the outside, with holes in it....?

I had one like that, and i think it was also red98 too, and i never really thought too much about it until i swapped it for the K&N filter about how ill fitting it was.
The K&N made a really tight, fitted seal whereas the other one probably had about 5mm play around it.
I doubt very much at all that it's anything to do with the year of the bike.
I would seriously recommend getting a K&N filter though, you can really notice the bike breathing better, and you only need to buy the one as they're guaranteed for a million miles, and you don't even need to clean it for the first 50,000 miles!
£30 on Ebay.

Just ordered one as I didn't change the filter earlier in the year when I changed oil and plugs. The last K&N filter I ordered was 4 off the little cone filters for my Honda 400Four in the mid 80's.

I remember being pillion on an X7 once heading towards a humpback bridge followed by a tight right hander :\  I was punching the pilot to slow down but all I could hear was his laughing :'(  Anyway we were home before the pursuing 250LC and CBX550. Those were the days and I don't miss them at all..............away camping every weekend straight from the pub into the tent and then back in the pub, no why would i miss it :\

seeing all thoes 600s at the london foccer meet has got me motavated again.....spent half an hour tonight putting the original carbs back together sliders glide smoothly and settle with a reasuring knock......iam now happy that the carbs are not causing the stutter  :) ........all my hopes are on the fuel pump and i dont know why i didnt check it in the early days of "stutter solution saga"..........so a question for you all....anyone had any problems with fuel pumps ?......bikes a 1998 , done 40000 miles and been well looked after ;)

I'm pretty sure bozboz had some issues with his fuel pump recently. They aren't overly expensive to replace though are they?
