Thank you! Now to figure out a way to plumb the return line into the existing plate on the gas tank.

Can anyone provide a picture of their fuel system upgrade for a nytro? I am curious how/where other people mounted their pump and regulator and where the best place to run the hoses are?

CR Racing in BC had a few kicking around so I got one from them. I was told heat and then getting snow on it could cause it. I am thinking the heat/extra torque is the culprit of it.

Perfect- Thank you for the info. I will keep my eyes out for a Nytro one then.

I started going through my 2010 Nytro turbo sled for next year and noted my secondary is cracked. I have seen spider cracks before and not worried too much but there are a few bad ones. In looking for a replacement I found some apex, vector, etc Yamaha secondary clutches for cheap. Are they...

Ah ok- Similar idea that I used to do for leak testing my 2 stroke motors. I will gear something up. Unfortunately the snow is depleting fast and with the covid pandemic we may not get up again to try it. I did run it on the stand with feather the brake to simulate resistance after I re-ziptied...

I am using the AEM Wideband You are correct- the headshim is supposed to be good for 91 pump fuel. I mix a marginal amount of C14 because 1) I have lots left from my race sled which will be no good by next year and 2) I don't trust the fuel around here to be true 91 anymore as I've seen it vary...

Checking the plugs at this point won't tell me anything as I drove it back to the truck about 1/4 throttle so it wasn't into boost so the plugs would look great. I tore it apart last night and noticed the boost line going to the MCX controller could be pulled off easily. Every other line was...

That was my thought as well that if it was that lean it wouldn't run normal. It wasn't near the rev limiter as it was only reving 8000. I put a new set of primary weights in afew runs ago and I am still getting them dialed in so I am slowly bringing the rpm up. It wasn't pulling over 8200 in all...

No the kit has been on the sled since new in 2010 and has 5000 km on it. I put lots of miles on it with it running consistently in the 12-13 range under 10psi boost. (full throttle) The 240 kit uses the stock pump bit it has additional injectors in the plenum. I started stripping it down...

I have a 2010 Nytro with a 240 MCX kit on it with the head shim. I had it out yesterday and it started running lean. Idle was fine 14, then cruising along up to 0 boost was 12-12, then as soon as it started building boost it leaned out. As the boost built it leaned down up to 17-18 @ 10 psi...

I am actually. I am going to sell the CR ones and just go with stock a arms for now.

XTX bracket Install, and Tunnel Dump Exhaust

Progress has been coming along. I had to take off the MTX front and rear skid mounting brackets and the rear tunnel cap. I got XTX brackets and cap installed now. While at it I went with the 141" AC skid instead of the 144" XTX skid. The MTX tunnel already had the holes for the XTX skid to the...
