I ride a 1994 440 XCR that has a redone motor by the previous owner. It has a pretty horrid bog off the line. I'd like to try and get this sorted out before the snow flies here.

I'm pretty much a bonehead when it comes to 2-strokes. I was talking to a few guys at work and they told me to check my reeds and they are just "behind" the carb boots. Well, I pulled the airbox out, slide both carbs out and unbolted the car boot and what do you know, no reeds.

My question is, does my sled even have them? Where should they be? If someone can even post a pic, that would be worth more then a 1000 words.

Thanks a bunch.

no the engine does not have them they did not put them in until 97 but for what you can do to make if faster play with the air screw and the jet screw in small incroments until you get it to run well and also you may want to put new clutch springs in they are probably worn out and it is engaging to early

are you testing this bog when its warm out?

I'm not testing it when it's warm. It was like this all last winter. From a dead stop to about 20 mph is so sluggish, then it hauls after that.

Guess that answers my question about the reeds.

No idea what you've done so far so I would step back and go to the basics. Confirm the carbs are clean on the inside, set both the idle air screws at something like 1 - 1.5 turns, and then synchronize the carb slides. You need to confirm they both lift at exactly the same time, and both reach full open. Then you need to set the idle speed. This is a pain to describe, but both have to be EXACTLY the same, carrying the same amount of the load at idle. Otherwise, and the one that's set too low will constantly foul out on you - sometimes causing the problem you are describing.

Others may have a different way of doing this, but the way I do it (AFTER I'm sure the throttle cables are set right above) is to make sure the idle speed adjusting screws are free. I screw them all the way out, then in with my fingers until I feel them JUST contact the carb slide. Then screw them in 3-4 turns (again, both the same - as a pair). Start the motor, and adjust both together as necessary to set your idle speed. Just remember, they are adjusted EXACTLY the same any time they are touched for any reason. You get to start over otherwise.

As mentioned previously, this is not something you want to do in warm weather. The idle speed will likely change a bunch from 50 degrees to 20.

If this doesn't clean your problem up, second thought would be clutching. Prior to doing anything there though, you need to know the carbs are right......
