Hi there. My foxeye has a really snatchy and jerky response when on only a whiff of throttle, say when your trundling along in traffic. Open it up a bit and it's fine. Anyone had this problem ? The bike had been sat for a couple of years before I bought her so im thinking maybe the pilot jets need cleaning ? Anyone done this and is it easy or best left to a mechanic ? Thanks.
-
Carb balance perhaps? Is it better at higher revs?
-
Yeah anything more than a fraction of throttle is fine. It ticksover smoothly aswell. Mind you, it wont start on a closed throttle you have to give it a blip to start it or it cuts out.
-
very easy to clean the carbs.. you have choices.. but some fuel addative which will go through the carbs and clean them, failing that you can remove the carbs, bit of a task but easy enough for any home mechanic with simple tools.. carb cleaner or compressed air will do the trick once dismantled.
If it had been stood have to replaced the plugs and oil?? Also would suggest removing the ht caps of the plugs and spraying wd40 into the caps.. let them sit for 10 mins, then reconnect(dont bother drying them out) just let the wd40 soak in. That may also cure the problem as the ht lead plugs oxidise..
-
Sounds like my foxeye too. Had the carbs balanced, didn't make any noticeable difference so I guess it's carb cleaning time. I'm not convinced I'm the best person to do that though ;)
Any recommendation on fuel additive as a first try? Boggo Redex stuff or is there something more capable?
Cheers,
Rob

+1 for wd round the ht caps first... Redex worth a try but never found it effective.. Had the famous 600 stutter before pulling away on my bike recently.. Turned out to be a duff plug so changed them. The tighter plug gap than recommended I figure didnt help either. If bike is rough all the way up to around 4k rpm then sweet as a nut, pilot jets and a carb clean looking favourite imo..

STP Complete Fuel System Cleaner.
Use a half bottle per full tank, over 2 tanks of petrol.

STOP!!!!!!!
Before going carb balancing and stripping blah blah blah try the silly route.
Squirt some WD40 between the grip and switchgear.
Then try ....
Worked for me

The throttle should snap back freely anyway, i would've thought that would be quite noticeable if that was the problem?
I wouldn't go too mad with WD40 in that area either in case it dissolves the grip glue.

When mine used to stutter a bit at low rpm I found there was some emulsified oil blocking the air filter, possibly from when someone knocked it over when it was parked. May be worth checking your air filter too?

Wasn't saying bather it over night just a squirt. If it doesn't help move on. Why look to the worse scenario first ;)

Yeah i'm hearing yer, it's just that after spending a while on here some problems sound all too familiar. :)

Just that I was having problems when I first got the bike with jerky engine especially noticed on roundabouts when trying to play at the begining of twist. But it sorted (atleast alot of) the problem when I fitted the the hotgrips and thus used wd40 to remove old grip.
Maybe my grips are too close to the switchgear and the disk in between gets mucky and sticky.

I remember shaving bits here and there to make things work for hot grips, BUT, my right grip doesn't touch my switches?
-
hot grips not the problem..........it was fitting in them that i used the wd40 and thus found the solution

Not trying to sound pedantic but it's nowhere near the switchgear!

Cant get my head round how wd around the throttle area is going to solve the original problem posted..

Unfortunately it is rocket science and it also isn't an expensive suggestion.
Hi my foxeye has really snatchy and jerky response when on only a whiff of throttle say when trundling along in traffic
the snatchiness could be from trying to control mm movements with a sticky throttle at slow speeds. Remember the plastic washer/disk between grip and switchgear. it's there to stop interference between the two, so it's logical it should be kept clean.
But as you suggest it probably is irrelevant and is so simple it's only deserving of being ripped at and not tried. ;)

What bike are you talking about?
As i said earlier, the throttle is not near the switch gear!
-
Just for clarification.....
-
Ah yes you are correct not near the any switch gear the damned throttle cable housing is in the way.
So let's stop being pedantic and read the throttle housing instead of switchgear. Sorry if throttle housing not correct term, I sure some one will correct using you pic.
Your pic, now if I were in your shoes and my suggestion was actually your suggestion as soon as I look at that pic and even with me being a tad thick I would suddenly see what you were on about.
But hey it was just a suggestion cheap and simple for which I apologise ;)

No apology necessary.
As they say, a picture speaks a thousand words. :)
-
If the above suggestions don't solve it, another possibility is the throttle position sensor.
Checking the adjustment is fairly easy (once you have the correct secure torx driver), but it may be there is a worn spot on the track of the potentiometer in which case replacement will be necessary.
