what would cause rpms to quickly drop away on a climb for a second and jump back instantly? happened when a buddy was riding mine, and when i was riding it down hill it seemed to act like it hit nuetral for a second then came back to full power. 05 renegade 800 ptec, i year old motor. clean clutches, bushings all good but the one in the spring cup was .002" over the limit. not great but i'm doubting thats my problem. i dont feel confident riding it far out in the backcountry as is, but i dont want to take it to a shop and dump a bunch of money in to it. its time to upgrade.
