Question about 2008 Triumph Street triple

1 Answer

Engine heat burning my legs

After being stuck in traffic, and so the engine gets real hot, i have experanced the frame (below the fuel tank) which is in contact with my knees gets so hot it burns me. Its only a short section of the frame from the middle of the fuel tank to just past were the seat meets the fuel tank. Funfortuantly this is incontact with the inside of my legs/knees.

    It has always happened since the bike was new. The engine is not over heating, according to the console display, and it only happens when riding in stop/start traffic conditions. On the freeway it’s fine. I guess in stop/start traffic the engine is revved more than idle. The heat seems to transfuse through the connection points where the engine bolts to the frame.

    Is this an ongoing problem like a manufacturer issue that you need to address or is this something new that has just started happening?

Is this bike air or liquid cooled if air cooled this is normal on a bike to get hotter in stop and go but if liquid cooled then your water pump is bad and not circulating fluid enough through engine head to keep engine cool.

On our 2011 Street Glide Trike, the air coming out on the right side rear over the engine is burning my wife as she rides, bad enough to blister her leg. Is there a fix for this ?


Since the introduction of the Twin Cam engine, heat has been a real problem. Go here and look at this site. http://www.nightrider.com/ I do not know if this works or not but the reason your engine runs so hot is because of the extremely lean fuel air mixture. The factory has to set the mixture this way in order to meet the EPA emission standards.

Good Luck

Hi, Quest25 the following applies to carbureted also fuel injected models and the usual suspects are:

1. Severely discharged or a damaged battery, 9 volts or lower.

2. Failed alternator/generator and or voltage regulator.

3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.

4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.

5. Failed system and or ignition relay, check for continuity.

6. Failed ignition coil, ignition/electronic module.

7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.

8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.

9. Air/fuel mixture screw improperly adjusted.

10. Water or dirt in the fuel system, carburetor or filter.

11. Restricted, blocked or kinked fuel line.

12. Fuel tank empty.

13. Gas cap is not venting properly or fuel tank venting system blocked.

14. A failed fuel pump, pressure regulator and or fuel injectors.

15. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.

16. Needle and seat stuck closed in the float bowl.

The oil tank gets so hot it burns my leg and when it gets that hot it want start


You must keep in mind that your Harley, unless it's a V-Rod, is an air cooled engine. It relies upon air moving by the cylinders to keep the engine cool. If you're doing a lot of standing still idling, your engine will overheat. If your bike is an Ironhead Sportster like the header indicates, the clyinders and heads are made of cast iron. This makes it even more difficult for them to radiate the heat as the aluminum cylinders and heads of the later models cool better. However, there are two things that you may wish to check on. One, is the ignition timing correct? Late ignition timing can cause an engine to overheat. Secondly, is the jetting of the carb correct? A lean fuel air mixture lends itself to higher engine temperatures.

Good Luck

check your spark plug and see what color it is, it sounds like you might be running really lean and that will cause the bike to run hot. if the plug is white or lighter in color thats most likely what is happing.

This is a common problem with this bike,and does not mean that the engine is overheating.Go to www.triumphnet.com and click on the "mods" link for a solution.
They show photos of the modification which basically consists of installing a mesh screen on the inside of the fairing to channel the heat away from your leg.Also the upper fairing vent is enlarged to aid heat disipation.

I have a 2003 twin cam 88, stock, and the rear cylinder is running very hot,so hot that the heat burned my wifes leg. please help


The TC88 engine runs typically hotter than the Evolution engine. This due to the EPA's stringent emissions laws. As a result, the engine is running very lean. The best thing you can do is take it somewhere that has an exhaust gas anylizer and have them adjust the fuel mixture. If the bike is carburated, a jet change is required. If it is fuel injected, a change may can be made in the fuel mapping. Call your local dealer and see if they can do this for you. Good Luck.

2006 road king engine heat


First of all, you need to install a temp gauge as, even if your motor is running within the red-line (below 300degF, preferably lower than 280) the exhaust can still be several hundred degrees. Even if you add most cooling units that claim to lower engine temperatures, lowering your engine temp as much as 20-40 degrees may lower the exhaust as much as 100 degrees or possibly a little more however, lowering exhaust pipe temps from 5-600 degrees down to 4-500 degrees is going to help your engine but, it is still going to produce a lot of heat radiating to the human body.
Have you tried the heat diverter panels that fit on both sides of the upper frame. they are made to divert heat away from your legs. Also, most of the Harley drill teams use a heat blanket that does the same thing. It works a little better but, it doesn't look quite as nice.
I have a new cooling system that actually does work well and is designed specifically for the conditions you described and it has worked wonderfully. It keeps the engine cool enough that the rear cylinder cut-out never even actuates. It completely eliminated the engine overheating issues. None the less, it is still hot on me even though I never hit the red line anymore. If your interested, I can give you the product name. I'll check this site occasionally to see if you respond.
Heat is one of those negatives that are going to occur when riding on an air-cooled bike with a V-twin as the pipes have to be mounted high under the rider. There are a couple companies that claim to produce internal ceramic pipes that supposedly removes nearly all heat down the pipe and out the rear yet, they will be very costly and I haven't heard any actual feedback from anyone using them so, it would be an expensive investment that may or may not remedy your issue.
Wish there was better news. If I had actual oil and/or engine temps to go on, I could possibly give you a better answer. Good luck..................Erik

2006 road king engine heat


I don't see how oil can cause an overheating problem. I think the service tech was screwing with the fuel/ignition map when the bike was on the dyno. Is it a F.I. engine? Lean mixture or retarded/over advanced timing will cause this, among other things. The dealer may have to eat the cost of repair if you can prove they caused the problem. An air cooled engine that overheats is gonna self destruct!! Get it checked out NOW.
