1999 Prairie 400 wont get over 20mph
Full disclosure I usually work on Honda ATV's. But, a buddy of mine bought a 1999 Prairie 400 for "a good deal" on local craigslist. It seemed to idle great and even rev up in neutral just fine, but does not accelerate past about 20 or so mph (cant tell cause speedo is broke). Prairie only has 1250 miles on it, so I thought no problem probably a carb issue from sitting. Went through the carb and runs even better now, but still wont rapp up /accelerate ike it needs to/should. Took clutch cover off and checked belt, few chunks on one side missing, so bought a new belt hoping that was it... Installed new belt and still wont increase speed to over 20ish.
In neutral, the CVT clutch system (front pulley) moves in and the belt moves up like it should??. When in gear (low and high) and under full throttle the clutch will move a little bit and belt slides up but only a little, does not come to even 1/3 as high at top speed as it does when in neutral. It also squeaks when in high gear and sitting parked with the new belt on it.
Looking for advise on how to fix this thing and if it is worth it? Anyone out there run into this issue before? I am 110% sure it's not carb related (have cleaned and rebuilt 50+ atv and moto carbs in the past). These CVT clutches are just new to me so any help is much appreciated. I did do a search of the forums but could not find anything that fit the bill. Prairie only has 1280 miles and 440 hours of use on it. Also checked spark plug and it is fine.
Thanks in advance from sunny Oregon
