Powderlites Turbo Nytro stalling problems Need Help ASAP

[Ironmanstl]

Hey guys would appreciate any help you can give me. We were in Valmount today and my powderlites Nytro kept stalling unless I kept the RPM above 4000. Once stalled, it was very hard to start. I had to crank it over for a very long time and give it full throttle, then release it for it to have a chancre to start. All that was done since I went to the mountains 2 weeks was install bar risers and a longer throttle cable. we disassembled and reassembled the throttle housing on the mountain and every thing seemed to be within specs.
My buddies are going to Clemina tomorrow and I'm going to try to fix this thing in the parking lot. I'd appreciate any ideas.
Thanks in advance.
I also posted this in Nytro General.

Sled won't start?

Check fuel pressure and hose to regulator.
Vaccum/boost hose off?

How many times will the vendor be first to respond?....

As usual, nice job Dave...

Keep Dave's # on your cell...he'll get it dialed...

 

[Ironmanstl]

Thanx Dave,
We checked all lines and pressure.
Had the tank off, etc.
All seems good.

I dropped it off to Darren at E&S.
BTW the new tune is great.

When did you upload the new map? After the last ride ?

 

[Ironmanstl]

My buddy and I ran the Dec2 tune last weekend.

stalling

Better check RB3 harness plug or something got pinch wires or tors system is not right? Any codes?

 

[Ironmanstl]

No codes,
I bypassed the tors hoping it was it but no dice,

I'll let you know what Darren comes up with.

Not starting when hot

Hey try and put snow on fuel pump to see if it has vaporlock or boiled gas in fuel lines.

Probably not a turbo problem but a yamaha issue.
