Indy trail 440 dies when warm

[beauvan]

Bought a 1992 indy trail 440. having some problems will post on forum and hopefully get some answers.
BOUGHT FROM NEIGHBOR WHO SAID IT RAN WELL WHEN STORED, OVER 2 YEARS AGO, i CHANGED PLUGS, PUT IN FRESH GAS, ADJUSTED JETS, AND RUNS GREAT, FOR 5 MINUTES..........THEN IT BOGS OUT LIKE ITS STARVING FOR FUEL, PULLING CHOKE HELPS FOR A SECOND THEN IT DIES...... IT WILL START AGAIN, THEN DIE AS SOON AS THROTTLE IS APPLIED. AFTER COOL DOWN THE MACHINE WILL START AND RUN NORMALLY...... FOR 5 MIN OR SO... THEN IT DIES.....ANY THOUGHTS?

Check the fuel pump impulse line for cracks and make sure both ends are securely clamped. Or better yet just replace it because the sled is 20 years old.

I have a 91 indy trail 488. sounds like a carb issue. check fuel lines, fuel filter,fuel pump check jets. check for proper adjustment on carbs.

Being stored for that long check your exhaust for a mouse nest, those little ******* Get everywhere and if it is it stinks when you burn them out. If it is do not do it in your garage.

all good advice, also check the vent on the fuel tank, this can be done easily by removing the fuel cap when the sled acts up and see if there is a hissing noise

The one thing you DIDN'T say that you did is to clean the carbs. Sitting for two years with fuel in the carbs will gum everything up badly. That pilot jet is likely clogged and not supplying the motor with fuel very well. Additionally, the floats may be sticking in the raised position and not allowing the bowl to refill with fuel. Typically, a sled idles for 2-5 minutes on full bowls of fuel before running out of gas.

Thank you, this was the case..... rebuilt the carbs....... runs sweetly! I appreciate all the comments.

Glad you have it running good again.

Ride safe!
