I'm scratching my head trying to figure out what's wrong with my 06 Switchback 900 as of late with running at wide open throttle (WOT).
A couple weeks ago out on a run on the trails the sled was running great, no problems of any kind. These were some tight trails without many long stretches so I wasn't really getting into WOT for the most part, but as I'm used to with this sled, the strong low-end torque would be pulling me at a good clip.
Finally when we got out into the first long stretch after about 30-45 mins of riding and I hit WOT to take off the sled sounded like it was missing and not picking up speed like it should (didn't pick up as fast as it was without WOT). I let off and it ran fine again at lower RPM, hit WOT again and the sled missed for another second and then opened up and ran like it should. There was some more consistent high speed sections and I was regularly hitting WOT with no problem.
Another tight section of trail, no WOT for a bit of riding, and then the next time I went to hit WOT same thing happened.
It's been a couple weeks and no matter the scenario this will happen. It "fixes" itself after you get in and out of WOT a few times and stays working fine as long as there isn't a big gap of slower riding. Then it will repeat.
I thought maybe it was the exhaust valves, so I replaced the bellows and cleaned everything up (weren't very dirt anyways) but no change.
I then made a TPS tool and did that whole setup, it was pretty much bang on to being with though, and again not change.
It's not gas because I've run 3 tanks through since the problem started happening and I can't figure this out?
Any help would be greatly appreciated, I'd like to have my 900 back to 100% for the rest of the year!
