yeah as soon as you told me about the play i hit me right away and i knew there was some play cause you kind of press on it barely and its loose before you even give it gas. Do you mean the adjustment is on the top where the lever connects? Did you have to adjust from when you first got the bike? I probably go and et house insulation and try it out dont want to spend to much. Well maybe later ill try the 46 sprocket but before i go do that i want to rule out any other adjustments that are possible before i go and do major changes. So what lupe would be good to use on chain.

 

There is a long bolt like adjuster in the cable approx 6" from the throttle housing. You should adjust that before making any changes. I use Bel-Ray Chain Lube but any chain lube would be good. I

 

ok i went home for lunch to see the bolt that needs to be adjusted. How exactly would you adjust it so the lever is correct?

 

OOO by the way do you know what type are the 4 screws that hold the rims in place. When i was riding some how 3 fell out and kind of messed up my rim but the threads on the rear axle seem to be ok. it was crazy cause i know they were tight cause i tightened them before. Im looking for replacements on all three with a little better strength. Dont know if you know but it would help so i can replace them asap.

You need a 8 and a 10 mm open end wrench. Or a couple of small crescent wrenches. You loosen the 10mm locknut and that long bolt will "lengthen" the cable and take up the slack. I like mine with zero free play but you dont want it so tight it increases the idle.

I think the bolts are 10mm but Im not sure of the pitch. That quad is at my shop so ill check it out when I get there in a little while.

 

well when i went home i was able to take off the locknut by hand so do i want to push the cable thats connected to the lever in to adjust the lever so it doesnt have any play in it. The screws on the rim are 13mm but do you recommend a certain grade for them.

 

ok i was able to figure out how to adjust the throttle but i have a question about the idle screw on carb. The way i had it adjusted was the idle screw was almost all the way in and would turn just fine when i built it. but if i un screw a bit it doesnt stay on. My Question is which should a adjust first throttle or idle screw? Or how much should the idle screw be in approx.? Also does the air flow mixture have any part of this so maybe i need to adjust air mix screw first? Im a bit confused of where to start??? thanks for all the good info mywifesquad i really appreciate it!

 

The head pf the bolt is 13mm, the thread is 10mm. Take one of your bolts to as hardware store and get grade 8 bolts. Be careful not to get standard bolts, 3/8" is very close in size to 10MM.

As long as you still have some play the throttle wont affect idle. I would start by getting the pilot screw(bottom of carb) set at 1.5 turns out. Fire up the quad, warm it up fully and adjust the idle screw. Then take the play out of the throttle while its running. BRAKES SET. When the idle raises you dont have run out of free play.

 

Ok i finally had the time to do some adjustment to the 250 sport.

I went ahead and adjusted the carb air flow mixture to 1 1/2 turns out. I still wonder how much the idle screw needs to be in cause i can do that and if i adjust the throttle cable so it doesnt have much play the bike idles really loud but the throttle lever dont have play at all and as soon as you push the gas it revs the engine. Not like before i had a 1/2 inch of play before it would take off so these adjustments might help for better riding i hope. So i just would like to know if i should tighten the throttle cable so it still has that play then adjust the idle screw and then take out the play from the throttle cable so that the adjustment is correct. Thanks for all your help mywifesquad

First off put some play in the throttle so you know it doesnt affect the idle. ONCE THE QUAD IS WARMED UP.....Adjust the idle with the idle screw and then while the engine is still running start taking play out of the throttle UNTIL the idle raises. Back off the adjuster in the cable until the idle drops and set the throttle play. You want the idle to be controlled by the idle screw and not the throttle.

Make sense?
