Working on a good friend of mines sled. Was sitting for an unknown amount of time. Drained the fuel, put new plugs in, pulled the carbs and cleaned them, put new petals in the v force 3 reed cages and the darn thing will not run right. It has uni pod filters and some kind of aftermarket can on the stock pipes. It starts up cold ok and idles nice but when you rev it up on the stand and let off it acts like the spark is being killed momentarily and then returns to idle normal. Took it for a tip today after it warmed up for a minute and it didn’t even want to take off. The more throttle you give it the worse it was. Acting like it’s on a rev limiter and backfiring through the pipes. Bully the time I got back it was running crappy on like 2 cylinders

This may actually be the TORRS. CHeck to see if your throttle cable is too tight. Should have some slack in it at rest. You can bypass it also to see if that’s it.

I tried unplugging it from the carbs

 

[super1c]

Didn’t plug them back into eachother?

No I didn’t know you had to do that

thats the only way to bypass it.

Ok thank you I will try that out. Not really familiar with Yamaha sleds of this era

 

[Manostihl83]

I tried eliminating the tors and the sled ran flawlessly for a few pulls. Then all of the sudden misfiring and randomly dying

Fouled a plug?

Literally just put them in before the run and doesn’t appear to be running too rich. Backfiring out the exhaust and intermittently dies as if you hit the kill switch

Strange. Once that’s bypassed it should be fine. Check compression. Maybe it let go.

 

[MrSled]

Also pull harness back under the motor and check for a rub thru.

It has plenty of compression. Looked at all the piston and bores and they look great

I like Mr sleds idea of harness. Even a bad stator
