Hey guys, I have a question about my 2003 650 Rincon I just purchased. THe guy that had it before me took really good care of it and kept up on the maintenance very well. It has done this ever since he's had it, it is very cold natured, if that's what you call it. When it's cold, not weather wise, but when its first started up cold if the choke isn't on, it has a hard time staying running. I know you're supposed to start it with the choke when it's cold, I know that. It will just die, the carberator has been cleaned and rebuilt, fuel filter replaced right before I got it, I just replaced the spark plug with a factory NGK plug. I mean my old 88 honda will start up and idle perfect compared to the Rincon. Don't get me wrong, she still runs like a champ with no hiccups, just this little nack when she's cold. I'm just wondering if there are others out there like this where they are just cold natured in that sense. Thanks for your input.

Ok 53 views and nobody has any ideas?? I find that kind of odd being that someone has something to say about everything...

I don't own a Rincon, so I don't know if they are usually cold natured or not, but I can tell you that a big bore is usually more cold natured than something like a 300, in my experience anyway.

My new 400ex is the same way. Have to keep the choke on for 3-5 min or she just dies. My 87 250r just need the choke on to start it idles no prob.

Before I put the 400EX carb on my 250X it would start everytime ...Try Pumping the throttle 4 or 5 times then just barely crack the throttle and start it and feather it for 3-5 min with no choke and see how it runs?

My foreman 500 will start on a choke, but it won't stay running if I just leave it idle. I have to baby it for a minute or 2 before it will run. After that it's fine.

It sounds like it's nothing to worry about. If it will start and run, and idle after it warms up then I wouldn't look for problems where they don't exist. :)

Yeah I was just curious... My buddy's 300 rancher is worse than mine. Who all has a Rincon, I just wanted to see how quick your throttle response is because mine is a little on the slow side. The way it is is that when you hit the throttle it seems like the engine plays catch up then once the RPMs get up its fine. Is this normal or am I just going crazy here??

Cold running Rincon

I have a 05 Rincon that keeps stalling out when you first start it even using the choke. The choke won't stay out so I usr a cloth pin to keep the chocke out until it warms up.

I have a 2003 Rincon and I just give it a few throttle presses and it usually idles fine, unless it is real cold then I hold about 1/4 throttle for a few seconds and is good.

I have an 04 and it does the same thing. The throttle response is just a big bore. I've got an aftermarket slip on pipe and jet kit and it is a little better than stock but still lags. If you pull up the rubber boot that is on the throttle knob there is a plastic knurled nut that you can tighten by hand and it will keep your choke knob out, so that you don't have to hold it. Tighten it by hand only. I usually start my bike and let it warm up while I am getting my stuff ready to ride.
