Running temperature of bike during racing?

Hi guys,

Bit of background, 2004 600RR - standard radiator, standard motor, yoshi full system, PCIII that mostly has a custom map etc. Now the question, my bike has always run hot on the track but it seemed to be even worse on Sunday when the air temp was about 32C (that's 90F). My bike was running around 115C (240F) down the straight which is VERY high but obviously this had a bit to do with the outside temp. My bike technician has advised me to install a bigger radiator because the standard ones just can't cope. Have any of you done this or added the secondary (underneath radiator)? How much did it help?

Also, what temp do you guys run when you're full taps at the end of a long straight just before braking?

Cheers!
Dale

my bike never sees anything over 220 degrees and that is usually while sitting on the grid. i have never looked at the reading during the actual race

I see 225 regularly in fl..............no radiator mods.. I'd like to do something to help cooling, our bikes do run hot. Especially in 96 deg heat in fl

What do you mean by this. Are you sure you're not running too lean? What about air in the system?

Sorry, bit unclear. My map was originally one off of the powercommander.com site but it has been modified extensively by Garth (my "race engineer"). He says it's not running too lean, actually it's spot on. It'll go onto Garth's new Dyno maybe next week and we'll know for sure if it's not too lean.

Not sure how he's setting the map but if he doesn't have an A/F ratio readout he's pissing in the wind. If he's just going by what the plugs look like he's probably off. With the EFI these days you can be too rich in lower rpm's but too lean in higher rpm's, where you're running most of the time on the track. Put it on a dyno with an A/F ratio readout. Make sure they remove the CAT or put the sensor(s) BEFORE the CAT, AND block off the pair valve so they can get a true A/F ratio.

Thanks NRR, I'll chat to him tonight about it as I'm dropping my bike off there when I leave work (RIGHT NOW!). My bike doesn't have a CAT anymore and the sensors have been replaced with those dynojet eliminators so at least that's a given! I appreciate the input :)

My RR ran at 95C with stock motor, full Akrapovic system, intake stacks and PC3 properly mapped with A/f readings corrected etc. I'm told it's common for RR's to run hot on the track.

I cut out the centre of the thermostat to try and help BUT you must blank off the coolant bypass circuit from the water pump to the thermostat housing or the coolant won't circulate round the motor properly. Can't remember if this leads to chronic overheating or cold seizures but either way it's not good. With the stat gutted it still got as hot eventually but took longer to get to the high temperatures.


I did some research into extra cooling etc because I was having the motor tuned - several places in the UK do larger radiators for the RR. Also seen quite few people selling off the HRC sub-radiator that goes below the standard rad, I was told they don't work very well and the ones for sale are usually unused.

possible air trapped in cooling system, are you running 50/50 mix or water wetter by chance? bleed system just to eliminate that possibility.

Thanks for the replies guys, bike is going to get a run on the dyno today or tomorrow before the race on the weekend and also an extended radiator and we'll see from there. If it's too lean on the dyno we'll do some work on the maps. I'm only running water as we don't get water wetter here and regulations prohibit anti-freeze. Oh ye, they're doing a mod to the water pump - bypassing the bypass I think!

if you think its a problem hunt down the HRC radiator kit, probably costs a good bit, but it may be worth it.

My '03 Harc-Pro Complete has the sub-radiator. I've never raced without it so I can't compare to stock. Temps in the Kanto plain region of Japan can reach over 40C. With the subradiator and water-wetter equivelant in the cooling system the CBR will maintain an average running temp of 80C-90C.

If you are experiencing high running temps it might be worth your while to look into it. Like I said, I got my kit from Harc-Pro (www.harc-pro.com) if you are interested just let me know and I'll see what I can do to help ya out.

Thanks so much rocketjockey, i appreciate the input. I'll have to see how it goes tomorrow and this weekend. Temps have been a bit lower this week as it's been raining almost non stop since Sunday night and the installation of a subradiator should help but we'll have to see. I'll let you guys know! Thanks again for the help.

Update

Had my first race this weekend (i'll write up a report later for you guys) and the bike temps were MUCH better. A sub radiator was fitted during the week last week and the bike was dyno'd and tuned - 107 hp now! My race engineer says that for some reason my bike loves fuel and it just wants to run lean the whole time. He says it's still got another 1 or 2 hp hidden in there and will try to get it on the dyno again in the next week or 2. All in all, the bike ran no hotter than 103C (217F) on Friday although temps were well down on what they were the previous Sunday at the same track. The bike felt awesome and I was able to get my times down by 1.5 seconds from the times I was runing on the Sunday before! I was well chuffed, pity it rained the next day but I'll save that for my race report.
