Hi i just acquired an 08 and It seems to run a steady 180 to 200 degree when I'm riding highway but In these city red lights I find myself quickly getting up to 230 and have the fans come on. Also when itsidlng it continues to climb.
My question is:
Is it normal for my r1 temps to never stabilize? Or do I need to inspect my coolant system for problems?

Well getting up to 220 in traffic and at lights is normal and is also when fans kick on. It should go down to 210 then fans kick off. If it is not going down when fans kick on something is not right. Are both fans working?? If so try freshening up your coolant after a good flush plus remove your radiator and spray all the bugs out. You could spray your radiator out while mounted I guess but then all that junk would end up all over your engine. Riding on the highway in hot weather I see 170/180. Never seen 200 before at highway pace. Mine is a 04/06 which is the generation before yours though. But I believe they ran about the same temps. The 09/14 which is the generation after yours runs a bit hotter. The highest I've ever seen is 221 but the fans had just kicked on and it started dropping.

230 is normal on a hot day in traffic.

I would drain and refill the coolant system with fresh coolant if you don't know when the last time it was done.

Engine Ice is a good coolant and won't kill your dog.

Several months ago, my temp got all the way up to 240! I had a red light come on so I decided to just shut her off! This was in +90 degree FL heat on the highway on-ramp, my fan(s) had come on but traffic was not moving! I sweated it out about 10 minutes after the temps had come down and once I got moving, no problems. About a week or so later, changed my coolant to engine ice and my running temps have come down about 10 degrees. No problems since. Normally, at pace, they [temps] are fine, now, they are even better. Although I do need to verify that both of my fans are working. I seem to remember questioning that some time ago.

My fans switch on at 230 I believe. I have had it get up that high a couple times in traffic before I realized it but I immediately shut it down and pulled over and took a break til they were back to about 190 or I had a good mile to run at speed. I have no issues with it over heating while riding. It prolly was closer to ur 170 to 180. I might be factoring in temps from just getting in the highway (Seeing as i dont have a right rearset I havnt took it in many long rides) I think ima let it get to 230 today at idle and let the fan kick on and check that both are spinning. Even at idle the fan should be enough to lower the temp back to 210? Next step will be co plate radiator flush and coolant change. I've heard good things about both engine ice and wetter water.

this has been normal operation for my 07 since i bought her new. this is a big reason why i dont like riding in the summer time(also underseat exhaust), but i get to ride all winter so its a wash for me. im not worried about the engine over heating. just uncomfortable.

Soon as my fans come on at 220 it starts dropping. Sometimes it may see 221 i guess it depends on the timing of the fans kicking on. And once the fans come on it drops fairly quickly as well. If it was to climb to 230 with the fans on I would think something was wrong. What year is your bike?? I've heard many 09/14 talk about seeing 230 but not a 04/06 or 07/08. I don't see why Yamaha choose such a high temp to kick on myself. I'm having mine lowered to 200 fan start by ivans performance plus I have also picked up a second lower radiator for additional cooling.
Could be that Hawaii weather 230 is definitely getting up there. Gotta think 230 at the radiator would put ya in the 255 range in the motor and this is just to hot for me for sure. Anything over 185 is costing hp.

It gets hotter in NC and SC than it does in Hawaii.

Before an ECU flash, a 09-14 can easily see 230°.

I have heard the 09/14 does run a bit on the warm side for sure. I mentioned it in post 2. If I had a 09/14 I would definitely upgrade the cooling system. It's the only generation that has a full size unit available that's drop in ready with all stock hook ups including fan mounts and all. Csf radiators makes it and if it was available for 04/06 I would have grabbed it for sure. All of the large radiators available for all other gens need fan mounts added and additional fittings added as well for street use being there all set up for racing. I originally wanted to pick up a full sized radiator myself but every one I found there was just too much involved. Stuff like adding fan mounts which is no biggie but also having to add mounts for different stock accessories and the thermostat bypass fitting and no telling what else. I almost bought csfs rad for the 09/14 to try and put on my 04 but then decided a second lower radiator should do the trick.

Since we're on the topic, last monday it was 107 in the valley (Los Angeles Area) and I was riding my 07 home. It was hot, but as soon as I hit the streets and stoplights, holy crap. It hit 230 and stayed there. I also needed to fill up so I pulled over in the gas station. Filled up and turned it on and it was freaking 260!!! Red lights galore! But as soon as I moved it dropped and fans turned on etc. But still it stayed at 230 at all stop lights. So Engine Ice is the best for this? Plus removing CATS should help alot?
