2018 Summit 850. just over 1K miles. Runs perfect right up until about 6100 Rpm, then starts bogging till about 7700 where it will not go any higher. Sounds terrible like my old RX1 Ton with a gutted exhaust. Any ideas? Plugs are on order.
Bog after 6100rpm
- Thread starter Falcon1772
- Start date
Check power valves, compression and that exhaust isn’t plugged or something hasn’t come apart in muffler.
It was the freaking plugs.... I don't understand how that is possible but I just changed them, took it for a test drive and it ran flawlessly!
