1998 Polaris Xplorer 400L transmission problem

[IndyKWG]

Hi Everyone, I recently purchased a very used 98 Xplorer 400L. I have had the entire engine rebuilt and that part works great. I've noticed two issues with the transmission. First time out it seems to only top out about 20 to 25 mph. I have replaced the belt and still the same. Second time out same speed issue. Now it doesnt want to stay in gear, high or low. Reverse is fine. First thought was linkage but since its both high and low I wasnt sure if wasnt something more. Then add the slow speed I'm really not sure. I have way too much invested to spend much more. Any ideas are truely appreciated. What type of oil do you run in the transmission on these. Like a dummy I never checked that when I had it all appart. Would a low oil level make it act like that. The thing will pull the front end off the ground at low speeds. Thanks

Your centrifugal clutch might not be functioning properly, the oil level or type might hinder some of the tranny functions. I would strongly suggest buying a manual, they are a must have for amyone who is going to be working on their own machines. Until you can get ahold of one, try calling a dealer and talk to a service tech, to see what kind of oil you should use in the tranny.

adjusted the linkage and added transmission fluid. Shifts very smooth now. I think the top end issue is the high speed jet. I premixed the first tank of fuel and I think its clogged. Something must have shifted on the mounting or something but the linkage took care of it.

GREAT!!! Glad to hear it was an easy fix.

The lack of top end could definately be the main jet, also check to make sure the float bowl vent tube is not clogged and that the float is properly adjusted.
