Takes a long time to warm up?

PostAuthor: p00tster » Mon Mar 20, 2017 12:11 pm

My 98 XV1100 seems to take a really long time to warm up. I usually start it with the choke on, let it run for a few seconds, and then completely take the choke off. It will hold the idle without choke when cold, but it idles around 150 RPM.

It usually takes around 15-20 minutes to get it fully warmed-up to the point of holding an idle at close to 1000 RPMs, and that's actually after cruising around with it under load. I'll also add that I live in California, where the temperature has been around 70's to 80's.

The amount of time it takes to get it fully warmed up seems to be a lot longer than I see for most on here, and the RPM difference between warm and cold seems more-extreme than what I've read about others.

For additional background, I had made this posting a while back:https://viragotechforum.com/viewtopic.php?f=4&t=55642&p=454930

Has anyone else had this issue before?

don't idle it long at 150 rpm because of insufficient oil supply from oil-pump;

my 1100 was also "cold-natured", but since it ran other-wise normally - took throttle without stumble, accelerated well, started everytime, I just enjoyed it. [esp. rush-hour "parking lot" in summer]

Thanks, Mark. It only idles around 150 RPM when it's cold, and since I'm usually moving in a couple minutes after cold-starting, I'm not too concerned about lack of oil to the heads.

Did your 1100 also take 15-20 minutes to warm up?

My problem may be unrelated to yours, but on my 81 xv750, it was very slow to warm up until I bought a Dynojet stage 1 kit. After installing, I could start up and drive right off w/o fear of stalling or careful feathering...

I always give my engine at least a minute or two to warm in the driveway, then drive easy until I get to the main road [~3-4 mile] usually by then it was warmed-up and ready to roll.
