Been trying to figure this rig out for the entire summer. Pulling my hair out.
Problem: Initially, it runs and starts very well. At WOT for more than about 5-7 seconds, it cuts out like someone hit the kill switch. This usually occurs within about the first 10-15 minutes of riding and persists. Hard to start afterwards but will start with a quick pull of the choke. Make a few hard turns and it’ll do it again and again. Low end power is great. Seems to get progressively worse as time goes on. Gets to the point you better start heading to the launch.
Attempts to fix:
New fuel lines and filters
Stator-replaced
Voltage Regulator-replaced
Carbs from another machine. No change.
Factory carb settings and adjusted. No change.
Plugs/caps
Dielectric grease on all connectors.
Inspection of each electrical box. No visible issues. No blown fuses.
Cleaned RAVE
Compression at about 145-150
To me it seems fuel related but that has led me nowhere. I gotta try something else.
Couple ideas: Run a separate fuel tank and/or tear into the exhaust and check for some sort of blockage. I have not inspected the fuel system inside the tank yet.
I work on outboards and sleds all the time. Rebuilds are not foreign to me. I know my way around any 2 stroke motor but I’ve been fighting this Doo for 2 years now. I would pay someone to come and fix it even. Been out to the lake over 20 times and everything results in the usual disappointment.
Any new ideas?
