    Swapping Sidewinder ecu

    Hi, I have a 2017 sidewinder btx with a PEFI multimap with dash flash and a 2018 sidewinder ltx with a hurricane flash, unsure of what the exact stage is as I recently bought the sled and the owner knew very little about it. My question is, can I swap ecu’s back and forth from one sled to the...

    Nytro starter selonoid

    The starter solenoid has been acting up on my nytro so I finally decided to buy a new one. When I went to swap out the selonoid, the new one has the connector going inside the selonoid coming off the opposite post. Can I just swap the terminals on the solenoid? Anyone else ever experience this?

    boos it fuel system

    A friend of mine is chasing the same problem right now. His sled is a mcx 19t however. Next thing to check is fuel pressure regulator. I also run boost it with 16t mcx kit and I can over fuel my engine easily with boost it. Both out engines are pretty much same.

    ZX2 - already broke something at 500 miles?

    Zx2 I had the exact same bolt shear off on me. Very few miles on my zx2 as well. Funny thing is one if my friends also has zx2 on his nytro, his suspension would not compress at all over the bumps, not even a little bit. I would have thought he'd be the one breaking bolts but nope. Mine broke...

    Powder Lite turbo

    I am running a powderlites stage 2 kit on my 162" nytro. I run 14-18lbs boost at elevation and it pulls good. Only thing changed with my kit is it has the boost-it fuel system instead of rapid bike. Previous owner installed boost-it due to simplicity of changing fuel numbers on the fly to...
