GFB Posted April 30, 2007 Report Share Posted April 30, 2007 Finally got some filters and took her out for the first spring run. It was running fine for about 15 minutes and then I came to a stop to turn around in the road and it wanted to die instead of idling. It just bogged and died when I gave it a twist at idle. Started after a couple kicks and made it back home where it did the same thing as I pulled it into the garage. It felt a little warm so I pulled the plugs and they looked nice and tan. I did notice during the last couple times I wound it out it didn't seem like all the balls were there. Where should I start? Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted April 30, 2007 Report Share Posted April 30, 2007 youre being pretty vague. we need more info. whats your jetting? what filter setup were you running? what you running now? what pipes? any engine mods? Quote Link to comment Share on other sites More sharing options...
Screaming Yellow Zonker Posted April 30, 2007 Report Share Posted April 30, 2007 A little more info would help figure your problem out. Is the clutch completely disengaging? How does it idle in neutral? Does it take longer to start than it use to? How old is the gas in it? The carbs might just need to be cleaned out well. Including all the jets and passages.

Bought the quad this winter and it was running a foam filter with airbox and jetting was great for 40 degree riding (did a plug chop and it was good). I removed the airbox, put on k&n dual pod filters, but the weather was 80 degrees today. I figured the more air would be offset by the hotter air temps as far as jetting goes. The plugs were nice and tan when I pulled them today. Topend has supposedly been redone about 20 hours ago with a port and polish, not sure how much oversize. Still has stock carbs, boyseen reeds, cages. Gas is only about a month old. Clutch is disengaging fine. I rode around for a while, including a few stops, before this started happening and everything was kosher. I'll start with some new plugs and do a read tomorrow. EDIT: somebody asked about pipes. It has FMF fatty pipes and FMF silencers. Edited April 30, 2007 by GFB Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted April 30, 2007 Report Share Posted April 30, 2007 so basically you never rejetted for the new intake and temperature? you need to do a WOT plug check and see how it looks. and we need to know what jets are in it..

Screaming Yellow Zonker Posted April 30, 2007 Report Share Posted April 30, 2007 How is the idle? have you had to mess with it at all? Quote Link to comment Share on other sites More sharing options...
GFB Posted May 1, 2007 Author Report Share Posted May 1, 2007 Idle was fine. Pulled the bowls off and found 260s in there. :huh: I'm gonna get a set of 280s and 300s and start by doing a plug read with the 300s. Quote Link to comment Share on other sites More sharing options...
GFB Posted May 2, 2007 Author Report Share Posted May 2, 2007 (edited) 280s seems great at WOT. I ran her hard for 15 minutes or so and did a plug chop. Good smoke ring at the base, nice even tan at the tip that faded to a light tan down the porcelain neck before the smoke ring at the base. Sound good or should I go a notch richer on the needles? No more bogging or puking when coming to a stop though. Hmmmm. Also at low throttle cruising in 1st gear it either loads up or isn't getting any fuel--one of the two. I was riding slowly along my ditchbank checking out deer rubs from last year (scouting for a good hunting spot lol) and I would have to blip the throttle for a second to smooth her out. I know the bike isn't meant for low speed cruising like that, but it just felt and sounded like crap. Would that be the idle screw I need to adjust?
