I was wondering what a fuel injected tuber runs for engine temps. My random readings are below. date - front plug - rear plug - oil dip stick - outside temp. Fall 08 ---- 261 ----- 294 ------ 150 --- 74 Fall 08 ---- 270 ----- 310 ------ 128 --- 74 Fall 08 ---- 273 ----- 316 ------ 140 --- n/a June 09 --- 246 ----- 298 ------ 122 --- 53 June 09 --- 210 ----- 323 ------ 152 --- 60 June 09 --- 259 ----- 308 ------ 115 --- 77 June 09 --- 260 ----- 315 ------ 160 --- 86 June 09 --- 251 ----- 300 ------ 106 --- 109 July 10 ---- 299 ----- 365 ------ 191 --- 95 July 10 ---- 309 ----- 368 ------ 164 --- 89 Aug. 10 ---- 292 ----- 347 ------ n/a --- 112 | ||

Oh yeah I used a hand held laser temp gun to get readings. | ||
| Ebutch |
I have similar results Too.Laser and Sun dash mount gauge.Bike is 1999 S3.1996,S2T runs 20 deg.cooler.  those temps Are Good!!! | ||
| Ebutch |
My Oil temps are much the Same!Is what I meant.  | ||
| Azrael_cervale |
Is that right? When it was the hottest outside (109) your oil was the coolest (106)? Butch where did you put your temp sensor for the gauge? | ||
| Shanetbolt |
My outside temps maybe inaccurate because I was measuring the surface I happened to be stopped at. Blacktop or concrete holds heat pretty well. I measured my oil dip stick with oil on it. Rather than pointing the temp gun directly in the oil tank. Anyone else know what their spark plugs, head bolts, even the head its self is running at? My bike has been radiating heat like crazy and my seat gets plenty hot all while doing 55 to 65 mph in 5th gear. It would be nice to know if other people are experiencing the same. Dealers all say "Buells run hot", well put a number to it, give me a temperature, hot is relative. I just got my bike back from a dealer and they replaced intake gaskets and said $350 please to get your bike back....next! Buell owners get no respect, my bike did not even get washed. I'm not trying to bash dealer service, I would like to know what temp other F.I. tubers are running at. I'm seriously thinking of replacing the F.I. with a carburetor. So please post some temp numbers, I can not be the first to wonder how hot is normal and when should I be concerned about damaging the engine. Yes yes the computer has limp mode don't worry about it if it gets so hot. Well it is not comfortable to ride anymore and it runs perfect. | ||

All depends on speed ,temp-outside.Hotest oil temps are at speed 70 mph up then they fall and rise at speed.Then Fall and rise and repeat,excetra. Denis I did as I was told Here on Bad-Web after engine or Return oil Line.My Head temp sens.is at rear head near spark plug.  | ||
| Ebutch |
I have measured three ways head temp hand held inferred,gauge head temp,oil return line gauge. | ||
| Ebutch |
your temps are not really hot!I put reflective adhesive material under seat and gas-tank.Helps! | ||
| Shanetbolt |
Thank you for confirming my temps are "normal". It must be me and getting older. I bought my bike bran new and the first 50,000 miles were great. The next 20,000 miles my leg and butt temp sensors have noticed a rise in temp. That is when I bought a infrared temp gun to take measurements. I guess the bike is fine and the problem is me. Thanks again, your bikes are sweet. | ||
| Ebutch |
And I have Factory fan,with switch by-passed valve-cover senser for fan,that hels too!!  | ||

http://www.badweatherbikers.com/buell/messages/476 23/384089.html That was my problem. | ||
| Ebutch |
Shane: PS my oil gauge was bad then and replaced it was not low oil pressure. | ||
| Ebutch |
Dennis got gauge kit at Haber-Freight. (Message edited by ebutch on August 25, 2010) | ||

If your fanny is getting a bit warm you could try that adhesive heat reflective material on the bottom side. I've heard it's made with pixie dust and really does cool things off. Some of the fuellers use it on the inside of their frame to keep the gas a bit cooler. | ||
| Ebutch |
Aluminum Matt adhesive on Pixie Dust does Work Reflects Heat away from your Butt!!!!!!  | ||
| Shanetbolt |
Thanks guys, I have the Buell fan kit from day one. My next try to reduce radiating heat is exhaust header wrap. Since the exhaust header measures 420 degrees that is the hottest spot to start with. Yes I have installed heat material on the underside of my seat long time ago. | ||
| Shanetbolt |
Head temp sensor sounds like an option. Maybe I'll pick one up and swap it b-4 I install the header wrap. Funny how the dealer had my bike in specifically for running hot and to check "ALL" sensors. No mention of head temp sensor, just calibration of TPS and AFV and oh yeah intake gaskets because the front intake had a leak. Dealer also told me no way to adjust fuel maps on the race ECM. Is that true? | ||
| Jramsey |
"Is that true" No dealer is FOS. | ||

Do some research on those temp guns. They are dependent upon surface roughness, color and aperture. While they are a useful tool, I have seen most people use them completely wrong... | ||
| Buellistic |
IMHO, on oil temperature ... The oil entering the engine from the oil tank should be no cooler than 160 degrees ... Returning from the engine the oil should be no hotter than the max. temperature of the oil specifications on the oil that you have chose to use ... "i" run a SPORTSTER oil cooler with a thermostat and a cooling fan ... Have a 110,007.i miles as of the last ride, so my IMHO'ions work for me ... | ||
| Ebutch |
Sloopy I check three different ways and the all agree with each other!!!!LaFayette my S2 runs on the Cool side Alum reservoir 130F at tank Mobil one V oil.Probly warmer at speed.131,500++++ miles and S3,1999 75,000miles runs 130F most of the time and at speed 160,175F briefly.I use fan as a comfort on Hot Days with manual switch between cylinders.It works and has worked for years for me.But you guys are right almost all the time!!!  | ||

I just found this while poking around on ECM Spy. As the engine on an XB typically operates between 180 and 220 Ok it clearly says "XB" which is as we know the twin spar aluminum framed Buell and not the tubers. My engine temps are way higher. I don't have ECM Spy or a laptop which is why I thought some of you maybe able to help. Anyone in Racine Wisconsin or close by that would like to help me diagnose what is causing my engine running sooooo hot? This message board only goes so far, it would greatly help to have another F.I. Buell to compare against in person. | ||

on a recent tuning log of my X1 the running temps were between 200 and 223 (steady temp). with an AFv of 100% and an outside temp of 17. A reecent idle adjust session in my garage, standing at idle the bike reached 220 degrees (viewed with ecmspy) with no cooling airflow, if i stopped the bike it would not restasrt smoothly and would throw error codes until cooled. But while on the open roads it runs great at 220 | ||
| Shanetbolt |
Thats what I'm trying to find out. Snowbees engine runs at 200-223 where mine runs at high 200 to mid 300 temp. HOT and I"m told my readings are normal.....anyone else want to post their engine temps? What can be done to reduce engine temps? | ||
| Slayer5690 |
I'm running at 200 to 220 degrees C based of the ecmspy, which I feel like is too high considering that I live in Tucson. if any one has any tips to help me run cooler I'm all ears. (Message edited by slayer5690 on August 28, 2010) | ||

If you run your FUEL/AIR RATIO at 12 to 1 you will notice your engine will run better and cooler ... | ||
| Snowbees |
Buellistic, what part of your fuel maps do you run 12:1, is that not a bit rich for lower rpm/tps. do x1's run better like this ? extra fuel = cooler engine | ||
| Slayer5690 |
I only have the narrowband O2 sensor to tune though and xopti helped me with an eeprom that adds more fuel and it helped but I'm still hot. oh and my afv keeps dropping to around 80% after about 15 min of riding. It has a new temp sensor and O2 sensor so I can rule those out. I'm trying to see if my problem lies in the closed loop area of my map snowbees: richer= cooler, leaner=hotter this is true for most engines to a certain extent | ||
| Buellistic |
Snowbees: "i" have a 1997 S3T which is carburete'ed and can be easily jetted for this FUEL/AIR RATIO from idle mixture, low speed jet, needle, and high speed jet with a FUEL/AIR GAUGE off the rear header(same place yours has a 02 sensor fitting)... Run OEM heat range plugs gapped at 0.030 ... Never have fouled a spark plug ... See you have a 1999 X1 which has fuel injection, although fuel injection is the best "i" never wanted a fuel injected model because at the time when "i" was interested they are expensive to tune ... "i" do my own tuning and to me it was cheaper to buy jets than a lap top computer and a ignition module with a tuneable program ... IMHO, the OEM fuel injections are set far too lean for an air cooled engine ... |
