Engine Running Temps???

[Welsh Wanderer]

Thanks a lot everybody. Really appreciate the comebacks. I'm well relieved to hear that other frames get just as hot, and yes I've got lowers on too, and grill protectors, and have noticed that the fan kicks in much more readily.

I did 500 miles over the week-end and at speeds of 70-110mph it's no prob and the frame stays pleasantly warm, but yeah, at town speeds for 15 minutes even though the fan kicks in fine at 104 c [ 220 F ] you wouldn't want to touch the frame.

But she's running great and I'm no longer fretting :<)

Thanks again, all,

WW

Can you get away with a synth oil with a wet clutch? I use semi syth [Castrol GTS] OK, but was advised not to use the fully synth.

Full synth should not be a problem, I run it as do many others & have had no issues.........

I use full synth with no problem (castrol syntec 20w50). Just make sure the oil you use is not energy conserving ( it will be listed on the API donut on the bottle).

A quick search would have found you the following

The service manual says the thermostat valve opens between 86.5-89.5 C (188-193 F). Before this the coolant doesn't even go round the radiator. The cooling fan kicks in around 100-104 C (212-219 F). The highest temperature I've seen registered is 109C (228F)that was back in the summer stuck in traffic. Once on the move again it dropped back to high 80's low 90's - but that sure cooks the frame temp. up some.

Average riding conditions: 88-90 C
Maximum temp from stop 'n go: 107 C

This is one hot running biatch! That's why I run a full synthetic Motul motorcycle specific oil. No worries.

I can't imagine what the temp would soar to if I had the lowers!

Yes, THANK YOU!

Seems we have this discussion every few months. No need for a new thread each time.

Sorry dadmun; I didn't know and couldn't see anything on the site!

I was actually asking about FRAME temperature, not coolant. the later's not showing a prob, but the frame heat was a worry as I'd not noticed during the previous 12000 miles that it was getting hot enough to burn skin when in traffic. If you check my original post you'll see that I only noticed this immediately after carrying out a full service including valve shimming, so I was worried.

Again, many thanks to those who put my mind at rest.

PS. How do you remove a thread once it's served it's purpose? I have no desire to clag up the site with a thread that's served it's purose.

*I* am sorry. I didn't read the thread properly or I would have seen your question about the frame not coolant.

My frame gets pretty hot. I don't know the exact temp, but I can feel it through my boots - I think moreso on the left side. I don't worry about it too much. I used the frame to warm my hands (through my gloves) in the winter time though.

If the admins see fit, they can merge threads, but since this is more about frame temp, it will probably just stay as is.

It seems mine is always at 218 Degrees

good thread.....well now that i've thrown on Jardine race-slip-ons i do notice that when sitting in traffic it gets up to 237 degrees : since i don't have a power commander yet, is this a sign that i'm running lean and if so could someone please explain the how that occurs( lean engine= running hot).

l/h side of the frame definitely gets pretty toasty when stopped. coolant temp will climb to 225 at a stop but fan pulls it down to 210 in a few seconds. on the elevated temps when running lean, i believe it's directly related to exhaust temps(egt). on my nitrous stang, if i get a little overzealous on the tune it will spike egt's to over 1500 degF. during a pass. this results in higher coolant temps on the datalogger and melted plugs and sometimes melted pistons. the a/f ratio when this happens is usually over 15:1. makes best power @ 11.8:1 on spray and 12.5:1 n/a.

I'll tell you one plan that opting to do next, primarily to keep my 03 1000 shock cool and have heard of other advantages in keeping the heat where it's supposed to be is exaust insulating rap from www.thermotec.com, I bought 50 feet for like 29 dollars us part # 11001, enough for the whole bike easy. They have many products, don't buy the tape, the glue burns.

Also in traffic (happily a rare occasion where I live) the engine tends to climb into the mid to high 90s very quickly.

What are The People finding ?

My 03 SV1K seems to run between 88c-93c then rises to 105 when at lights ect when out on a SV ride out my bike seemed to run about 5c higher than the chap who pulled up alongside never seen higher than 106c though

I generally run about 190-195 F when moving along at highway speed depending on air temp. Stopped in traffic or creeping along I hit 200+ F pretty quickly. The fan seems to kick on at 217-218.
