Noob Q about 990 Adv.

[tilting40s]

Hey guys I just purchased a 2007 990 Adventure, and it run like a bat outta hell, but (I think) it runs hot- 4 bars on the freeway and the fan kicked on after only 10mins in stop and go 60 degree out. The guy who does the TuneECU in San Rafael re mapped the bike for the prior owner and it's the dyno print out on the front page.

I was wondering if running the bike less lean would be a solution to cool the temp or if this is completely normal operation for the bike. I've done some poking around and seems that people have operating temps all over the board.

To be honest I am really not concerned with peak horsepower or torques just a bike that will run for a long time. Thoughts, advice, tips?

The fan doesn't mean its running hot, flashing temp bars does.

I'm no expert. But mine does the same thing and its a 2012 with 5k on it. Pretty normal from what I know. Many on here have done a dual fan set up to cool it quicker but I would guess its only necessary if your running in very hot climates or high rev slow movement situations. I kinda like it kicking on in the cold. Great way to warm up my hands. As far as running it richer to cool it I suspect that could create a slew of potential problems. But again I'm no expert.

^catalina38 That would be overheating, not running hot. I don't think the bike is going to overheat I just want thoughts on the current running temp and if cooling down the bike by enriching it would help and if sacrificing performance for longevity would be a good idea or even work.

Richer jetting might help a very little bit. But the temps you describe are the same as mine. (Now at 54,000 miles)

This. The 990 is just a warm blooded bike and 4 bars on the freeway on a California cool day are normal. We did some double track and fire roads the other day, and the fan kicked on a couple times when OAT was in the high 50s.

thermostat doesn't open till 4 bars.........70c

This is another solution you could go with:

My opinion is that the bike was designed to run on the warm side. The bike's cooling system went untouched for many years, so if it were an issue, it likely would have been addressed.

Sounds normal to me. When I first got mine I thought something was wrong as well!

[Katoom72]

All KTM's run 'hot'. They heat up pretty fast aswell. :)

If the bars don't go up in slow traffic then there is nothing wrong. I can leave mine at the doorstep running for hours if i wanted to.
