Been dealing with this issue for a few years, she bogs when hot and heat soaked. But runs fine below 6200rpm.
Spliced in a fuel pressure gauge to my bars (and yes I purged the line). In the shop- 45lbs at idle. Holds 45 for a while after stopped.
On the trail- waited for the first fluttering the trail, look down and 20lbs. At about 6600rpm. Let off and back to 45.
Rode 15km trail not stopping, heat soaked the engine. Coolant gauge showing 45deg. Super warm and humid out almost raining, above 4 deg temps.
Get to a spot I can climb- to the bar and immediate bogging and have to pull out, look down and 10lbs fuel.
Idle it down hill at 20lbs. Shut off, gauge springs back to 45lbs. Turn on and idle and stays at 45lbs. Super funny that it springs back to 45 eh.
Trail ride down off the mtn. Got it to bog a lot corresponding to 10lbs fuel. Come to a stop and as above, she’d be at 20lbs. Hit the kill switch, pops back in the low 40’s. Start it again and back to 45lbs. Take off and down to 20. Pin it and 10lbs and bogggggggggggg. And repeat.
No hot start issues ever. But I have electric start also. Have issues at idle when cold and often have to restart it.
I’m pulling the gas tank and pump today to see if the regulator is sitting ok.
Coils both at 1330ohms.
Don’t have pump resistance values that I can find.
I have a water separator on my fill station in the shop.
No check engine light ever.
Been searching the three forums and I’m not finding any posts about fuel pressure while running. On my old m-1000 cat, she ran at whatever pressure I set my regulator to all day long. Should be the same for any sled shouldn’t it be??
Any tips appreciated.
