[Lester]

My nytro doesnt want to start when cold,once you get it started it starts fine the rest of the day,let it sit 2 -3 hrs starts right up,sits overnite and no start again.any ideas?

With it being fuel injected I am wondering if it is a fuel problem where turn the key on and wait for 20 secs then try starting it. Could be a priming issue?

tried that,you can run the battery down sometimes tryin to get it started.seems like its not getting enough fuel .It backfired once and,since that it has had this problem.

You may want to take a closer look at your aftermarket fuel pump. That sounds like the culprite...Give Allen a call he may be able to support as Im not sure what fuel pump he uses on his kits..

Had the same problem yesterday morning. Both Nytros in enclosed trailer for 12hrs @ -10* F. 2010 started very hard, 2012 not as bad. Had to let them warm up 5-7 min before they would even move!

I found AMSOIL 0W40 helps a lot for cold starts. My first RX1 used to shake and sound awfull after cold sub zero nights out on trips. I switched to the 0W40 and it started easier plus the shaking and sound was much more like normal. I've been using it on all my 4 stroke sleds since 2003

I have been using the mobil 1 0-30 in my nytro and also used it in an apex a few years back. No cold start issues. Less drag on the starter.
