Last ride of the 2024 season sled ran perfect, wanted to do some upgrades before the 2025 season, started the sled with 3 pulls and rode it up to my garage, no issues. Removed the head and installed a SLP head and a clutch kit for it, and installed the new map for my current setup. Went up for a ride after and as soon as I hit the throttle runs perfect up to 7k rpms and bogs out. Checked plugs and they were really oily. Came home inspected everything! Put clutch back to stock, cleaned powervavles. When back up riding, with a friend with the same sled. Still can't reach more than 7k rpm and bogs. Swap power valves and tried it, still the same. Swapped dynojet controllers, still the same, checked compression 120psi on both cyclinders, swapped, clutchs primary & secondary still the same. Came home, and order fuel filter, pickups, and fuel pump. While wanting for parts I cut out the filter and bypassed the filter, ran it again and same 7k rpm. Next im waited for a fuel gague to check psi but haven't got to that. Anybody had this problem?? Or have ideas??
