After I rebuilt the card it seems to have a faster idle than before. I have tried to adjust the idle screw but will only speed idle up, not slow it down. What should I look for in adjustments. I purchased a card rebuild kit.

There are 2  screws that  affect the  idle .. The  idle  air screw and the  throttle  stop .   You adjust the  idle  air  screw to  get the  best  mixture at   idle. .   When  set right , it  will   have  close to the fastest  idle,  and  not stumble  when  you   open the  throttle.  The  throttle  idle  stop  is  just that .  It   sets the minimum throttle  opening.  That  is the  one  that   will  set  your idle  when the  idle  mixture is right.

Take another look at the position of the throttle cable and make sure the clip on the long needle is in the middle.  Those shuttles can be a little bit of a torture if the cable isn't connected properly.

      I suspect this bike may have a bad speed limiter. The part number for is 4060204. I found this one on ebay but it has a part number that is 1 number different. (4060203). It has the same LR44-2 and says its for a 94 Magnum 425. Will this one work on my machine or do I absolutely have to have the 4060204? Your advice would be appreciated. Thank you

      Just thought I would start a poll on this topic manly because I'm not a fan of belt drives. Just want to know which you prefer.

      I have replaced the cracked stator cover on my non-running 2006 LT-F400F that I purchased recently, checked all the shafts vs the service manual and pics and advice here.  I replaced missing gears, bushings and washers, made sure that truth marks were all aligned properly, that the shift cam springs felt like they returned properly, etc.  IAfter installing the new stator cover I checked the transfer lever for proper movement from L-H-R and then cranked it up.  Happily, it runs and changes gears well in L,  but it will not shift into H or R for anything.  I have opened it back up and am going back through it looking for the missing puzzle piece(s) but how can I best check that I have everything right this time before buttoning it back up?

      Did a top end rebuild, honed .010 over, new piston, rings, valve seals, etc. When i re assembled i only had like 30 psi of compression but then after it sat all night i now it seems to have gained some somehow, there is much more resistance pulling it over and i even got it to fire for a few pops. Issue i got is that it makes a loud squeak noise through the intake i believe (goes away when throttled so something with carb area) and it seems to not want to run well. I took head cover back off and timing seems fine so im not sure if something is sticky and that's why i got some change over time or maybe the valve lash is messed up after doing all this, i did get another cam for it but i wouldnt think it would make enough difference to need to re lash. Any insight on next step would be appreciated, i will be looking up how to do lash on these because it is a very weird angle to slip a feeler gauge in. 
      Actually cam is slightly off now that i look at the picture, thought it was good while looking in person. Hmm.

      (Question is at the end if you want to skip my blabbering) I got this unbelievably well taken care of Grizzly 350 in for a carb clean, it belongs to an elderly couple that bought it brand new in '07. Apparently whoever has been doing their oil changes for them never checked the air filter..
      Obviously it got debris in the carb, it would still run but only idle with slight choke. I've taken it apart and cleaned it, have new o rings, gaskets, etc. As far as the mixture screw is concerned, I'm assuming I obviously need to remove the plug. I'm mainly a lawn equipment guy, I've worked on slide carbs in the past but never an unmolested one with the plug still intact. I hate to mess with it as the carb had very little debris but I'm sure the o ring needs to be replaced at minimum. Finally, the question: what's the best way of removing the plug? I DO NOT want to mess up this carb..
