1980 liquifire dies on hard right turns????

[smitfire]

youd be surprised what weird problems are a fuel pump... the limiter wont matter
will it doing it wide open across a field?

No, I held steady speeds of 70 mph plus down an old railroad grade and no problems. If I'm going 10 or 15 mph down my ice driveway, hit the brake, and swing the rear of the sled around like a fish tale, the motor will bog down to 1500-2000 rpms. If I immediately give it gas as it starts to die, that's when I starts to cough and sputter or even die. I have idle speed set to 3800-4000 rpms. Maybe that's too high? The faster I go and the harder I brake and steer to the right, the lower the idle goes.

Do you have to be turning? Does it do it if you just hit the brake? If so, it might be the belt is too short, or the clutches aren't working 100% correctly. Just a thought.

I can't remember for certain, but I'm pretty sure the 1980-84 Liqs had a throttle safety switch. And if it does, I'd bet that's your problem. Either the throttle cable adjustment needs to be fine tuned or the little micro switch in the throttle lever control block is hanging up.....possibly the throttle lever pin is binding and causing the lever to not travel freely in the pin slot. You might try disconnecting the engine kill wire and taking it for a short test run to confirm that it's a problem with the throttle safety switch........BUT Remember that you'll have no way to shut off the engine in an emergency other than flipping the choke on which isn't a very quick way to shut it down.

If you checked the carbs again then I would try to disconnect the rev limiter. I had to run with mine disconnected last year
when it acted up in strange ways.

Uhhmmm, not to state the obvious, but...uhhh, just don't turn right? Problem fixed!

Happy New Year!!

Today's attempts included the following:

-Disconnect throttle safety switch and kill switch, still dies.
-Swapped throttle safety switch plug and kill switch plug around, still dies
-Tried not turning to the right, problem solved!
-I am wondering if maybe one of my floats is leaking or something, I going to try plugging in a new rev-limiter tomorrow. I never had a rev-limiter in this sled, I removed when I bought it. Luckily, I have a NOS one. It's going to be in the 40's the next few days so we'll see how much testing we can do. I also might try to take the hood off and ride around and observe things, see if somethings obvious. Please continue to say any suggestions...even if they seem crazy. Thanks for all the help, Luke.

Just a thought.

Might there be some bare wires in the wiring harness?
When you turn to the right the steering shaft might contact the wiring harness. If the was some bare wires in there it might short out.

Try having the sled idle and turn to the skis to the right when you are not moving.

Another possibility might be that the steering shaft pinches a fuel line when you turn.

Good luck

ok last and final straw jackit up under the rear grab bar run it half throttle or full and turn skis ? if that doesn't do anything something may be binding like Brian said like on your drive shaft and track while turning ? Do you run an airbox on this sled ??

[deereoftheyear]

Thanks for continueing to read the topic. It's 45 degree here today in Wisconsin, but tomorrow it should get colder. I will try the jackstand idea then. I inspected the wiring VERY closely and found nothing today. I have a stock air box and hose clamps to the inlet of each carb. It also has the stock wire mesh tube in the air box as well. I'll give an update tomorrow, too warm and rainy today to do much else. Thanks all, Luke.

Is it possible that there may be a bare wire on the kill switch that rubs when turning right--I had this happen on a sled once only shorted out when it turned a certain way.

I think making sure your belt tension is correct is a good idea. If the belt is too tight that could cause your engine to start to die out.

I just got done adjusting mine today!

Happy New Year...!!!

broken motor mount?

[Liquifire 4/6]

Did you ever figure out what the problem was?
