lol its ok bc dan, i dont really think its the reeeds, at least i hope not, so should i screw the throttle adjuster all the way down so at least the slead is all the way down on the carb and try runnin it again? last year the stator was bad and the cdi box was new if i run it could the bad stator possible wreck the new cdi box and cause a spark problem, the stator is new now but im tryin to eliminate other issues, thanx brandon

did a compression test today both cylinders are just under 130 psi
i think its just sumthin messed up with the carbs??

Even a carbed sled with reeds will spit back a little when running.
I suggest that you start with new plugs and then work you way back toward the coils, checking every connection as you go.
The problem could be as simple as a bad end cap, or a poor connection to the high tension wire. Unscrew the end cap and check the inside of the wire end. Clip off a 1/2 inch and reattach the cap and see if that helps.

i will try that, do you think running a bad stator could ruin my cdi box some how? i heard it can, also the only other thing i can find wrong is the ignition switch is bad, its hard to turn on the on position and when it turns to the on position i dont get spark sometimes so thats definately bad would this have anything to do with it? i put new fuel and plugs in today runs the same, im ready to give up and take it to a shop but i want to fix it myself and not pay someone else, im not rich, thanx for all the ideas.

Yes, bad switches can be very difficult to trace, and can cause all kinds of spark related problem.
Have you tried bypassing that switch yet?

bdavis1 · 08-21-2008, 11:21 AM

no dont know how to do that ill probably just order a new one then snip the plug wire ends and try it again.

**RJ Gleason** · 08-22-2008, 07:49 AM

It's a "closed system" which means that you have to have a closed circuit for there to be spark. To bypass any of the switches in the system, you just have to unplug them and then jumper the plugs to get spark.

bdavis1 · 08-22-2008, 04:55 PM

the ignition switch and the kill switch on the handlebars were both bad, found a few cracked and bare wires on the handlebars taped all them up snipped the plug wire ends will give a result later tonite

**RJ Gleason** · 08-22-2008, 09:21 PM

Now you're going in the right direction.

bdavis1 · 08-29-2008, 07:46 PM

ok heres the update replaced ignition switched bypassed the handle bar switch into a new tether switch fired it up got it to idle good put belt on and it does the same thing!!!! messed with it a little then my throttle cable broke so i quit.

can it still be electrical? (can sled shop test for wires that are grounding out?)

can it be a read?

can the belt be wrong size? (just bogs down when the track is up in the air)

could there be the wrong jets in the carbs and i just gotta wait til its cold? (dont wanna work on it when its freazing) my 88 wildcat started up and i was able to drive it around about a month ago.

come on guys think help me fix this P.O.S so i can work on another project!!!

bdavis1 · 08-30-2008, 10:39 AM

this is an update on my problems with my wildcat, when running and track up in the air engine bogs and seems to have no power and it will smoke alot when i got the throttle down, ive cleaned carbs ive checked all the electrical taped up some wires that were bare in the handlebars, replaced some switched thought i had it fixed fired it up got it to idle good but under power still does the same thing,

can it be the jetting in the carbs? had my 88 wildcat runnin last month and that drove fine,

can one of the reads still be bad?

can a sled shop or someone test the wiring to see if its grounding out somewhere?

can it just be too warm? (like i said i had my 88 wildcat runnin last month and a few weaks ago my buddy had his polaris out and driven it?

please help me fix this problem!!!

JheLrey · 08-30-2008, 12:43 PM

Too warm, too much oil, dirty clutch/secondary, etc.?

bdavis1 · 08-30-2008, 08:04 PM

i sprayed the clutches with brake cleaner and blew them out they look pretty clean, and how can i be gettin too much oil themarks on the oil pump lever match up perfectly? thanx brandon

**RJ Gleason** · 08-31-2008, 05:57 AM

Does it still have the same gas in it from last season?
Try it with fresh fuel in it.

**RJ Gleason** · 08-31-2008, 06:07 AM

Air temps too warm for the jetting will make it rum poorly.
Also, old gas will not run well.
Try fresh fuel in it.

bdavis1 · 08-31-2008, 11:56 PM

yes have put fresh gas in it, last month i had my 88 wildcat 650 runnin i drove it 4 a minute and parked it, so it ran ok when warm, my 90 doesnt even really move would the jetting in the 90 wildcat carbs be different than in the 88? i know the carbs are bigger in the 90 than in the 88, so can it just be jetted different?

**RJ Gleason** · 09-01-2008, 05:00 AM

Larger carb will have different jets, and that can be a huge difference in warmer weather.

bdavis1 · 09-01-2008, 06:45 PM

so if the person before me jetted it to run in minnesota or somewhere that could cause a problem? i dont know were the original owner use to drive it. also would a bad secondary clutch cause my engine to run like this? i though belts were suppose to be easy to slip on and off? mines very hard to get on and off, but my track spins freels good bearings.

**RJ Gleason** · 09-02-2008, 07:46 AM

The wrong belt (too tight) can cause problems. Check the belt # to be sure it's the right one.

bdavis1 · 09-02-2008, 08:30 AM

its the right belt. could a bad secondary cause all these problems with it not wanting to move?
