not always that hot , but yea they have a tendency to run higher than other bike

 

+2
half the shops out there dont know what there doing

 

I had the same issue after a year on my 06. it ran great at 1st, thru canyons, highways, etc. would be about 147-177 max. Would get hotter in the city of course. but one day started overheating bad. was leaking coolant out of the overflow etc. got it pressure tested, shop said radiator was fine, fans were working, thermostat was working, they could find anything wrong. After a couple trackdays a fellow ride asked me if I was having overheating problems. I said how'd you know? He said it was a common issue on the 06 636's. Mostly the ones ridden hard (track bikes/ stunt bikes), best solution was to get a race application radiator or hook up a secondary fan on a switch that can be ran at all times. I never found a solution that worked, but I know a lot of people with the 06 636 that have the same issues, and I also know people that dont have the issue. Most that do have higher miles on their 636. I think that the CLR trick may work, since it's the only thing I never tried, but I've personally have had the issue and can void out the radiator, cap, water pump, thermostat, and coolant being the major issue. good luck to ya man. Sorry bout the page long rant.

 

asked my tech, he says that's completely normal, but if you want it to drop about 20* then switch to Engine Ice.... make sure to completely flush the entire system with mineral water (baby food isle is cheapest).

 

my 05 runs hott all the time and so does my buddies who has had it since 05 when it came out he said his has been doing it since he got it

 

+1 they run hot. DON'T use ENGINGE ICE. Does not work on the kawi's. I use Water Wetter and distilled water. Works the best. Bike runs around 205 in the lot. With the engine ice I was at 220.

 

I always thought mine was air cooled like a Hardley.

Could fry eggs on the radiator! Hmmm not so bad without all the road grit.

 

haha..Thanks guys there are a few fins pushed in but I dont think its nothing too serious I'm going to flush it and try the water wetter..let ya know what happens...Jason

 

when you flush it, look in and see if there is any build up in there. If so, try the CLR trick. I know it sounds like BS, but it works.

 

i run engine ice and i run 207 at the lot

 

Did you just write that? Are you seriously trying to say that the physics designed into 2 watercooled internal combustion engines makes a difference? Or that Engine ice is not compatible with Kawi's but works on other bikes?

I agree water wetter is a good product also, but BOTH will work on ALL brands of bikes.

 

sorry Jeff, your gauge must be wrong...

 

well thats no good then

 

i never seen either product work any better than regular coolant

 

I have on track bikes, and Busch cars, but then again, you can't run coolant on tracks...

 

I was thinking the same thing.

I got no gauges anymore so ...

Haven't blown a head gasket yet so heh.

 

have you compared them with coolant then with water wetter or engine ice ?

i have seen so many people try both products and it never made one bit of difference .

 

I have only used them on straight racing engines, the advantage to us was that when diluted, water wetter would be clear and not look like anything but water. It was an unwritten rule that all the Busch cars ran it..... NASCAR sanctions at the time required that you only run straight water due to the fact that coolant was also a great track lubricant once leaked out via wreck of mechanical failure. So I have no direct comparison to running a coolant vs. wetter. But as for running straight H2O to a H2o w/water wetter, the differences were quite noticeable under race conditions. But Water Wetter works best in a high transfer rate situation and this was under extreme heat build up (high RPM) and extreme heat transfer (high air speed through rad), as for our unique situation, I'm not sure that this is the best bet.

I can say this, I am currently running straight water right now and see 218-220 when the fan kicks on and I never see higher. I have never burped/bled my system, but it's only in the high 60's right now. Jeff was at the lot the other day with Ice in his bike and only got to the low 200's. I'm only running straight water for a few days, total breakdown is coming this week.

I just googled glycol coolant boiling point and got some good info.

 

ya thats whats in most coolants and running straight water for a long time isnt a good idea because it doesnt lubricate or fight corrosion , now i know you know all this but figured i would spell it out for people reading this thread who might not know

 

You're not using tap water are you (I'm sure your not)? Calcium deposits will wreck your radiator. RO or distilled would be the key. Anyone planning on running plain water needs to be careful of the corrosive qualities it will have on the aluminium core and change it frequently.

Just my again ... ha ha ha.... I'm losing money fast tossing pennies around!
