Why?Most four strokes do like to get a little warm when just idling. But if it's real bad check your radiator fluid (of course) make sure its filled to the top of the fins, not to much over or it'll be overfilled. Then also look for air leaks. If there is a hole in your rubber piece leading from your air filter to your carburetor or anywhere where possible air can get into (and isnt suppose to) that'll heat up your engine to. If it tends to rev weirdly, like after twisting the throttle doesn't drop back down to idle quickly, then theres probably an air leak. One other thing is, check your jetting, if its set too lean then it could overheat to. this mainly is cause by after market parts (pipe mainly). To see if it's too lean, your muffler will have a sort of whiteish look on the inside of it. I'm not sure on what else to check. But if you do have an after market pipe, check with the makers to see if they have a recommended jet settings.,,,

Why did I was my 2005 Ultra Classic trike engine shut off while driving, start back up, went a few miles, before shutting off? Is that the kill switch malfunctioning?


Sounds like you may be low on oil. Bike runs until oil is pumped on top of engine, and not enough remains to coat the sensor. Engine shuts off, oil returns to reservoir, bike runs again....i guess that's why they call it a motor cycle....

Engine cuts out


Try this. When you get to work leave the bike running and turn the fuel selector knob to off and let it run til it cuts off. It will drain the fuel from the carbs and trap the rest in the tank. It removes the air bubble in the lines problem so when you get ready to leave, switch the fuel on and wait a few minutes then crank her up and ride.

There's an idle adjustment screw. The bike runs faster when cold because the fuel\air adjustment is richer on a cold engine. When the bike warms up, the fuel becomes more lean in mixture because the heat causes the fuel to expand, i.e., less molecules of fuel to the firing sequence of the piston. When the bike is warmed up, after say ten minutes, the heat causes a leaner mixture, so adjust the idle on a hot engine (about 1000 rpm more or less). The bike will idle faster when cold, then drop rpm's as the engine warms up. Good luck

Check if the charging system works ok.
At idle with lights off, you should see 13.5-14.5V on battery's terminals and 0.5V less with high beams on, at idle speed as well as at 4000rpm.
Use a fresh good verified battery to take the readings.

Bike starts and runs but when it warms up (running for about 20 30 minutes) it won't start back up until it cools down...and it's not running hot...can you please assist me


Overheating. The raditor coolant or the cooling fan is'nt working corectly the engine should be as hot as it's going to get in 5 minutes then the therostae opens to start keeping it at the same temperture if the coolant or the fan can't keepit at this temperture it'll not restsate till it's cool enough to be in the safe range agin. Some times not changind the oil often enough can case this problem too low coolant and the fan not working all can cause this after finding the coolant system problem and fixing it change the oil as it'll be ruiened from the overheat. Low speed hotrodding and stop and go traffic can trash the oil and just a few hot runs acan make it need and oil change as the oil fails at high tempertures and the oil is an important part of the cooling system as it's cooler beng clean and in the air flow. As the oil cooler doesn't have the benifit of a fan sitting running and hotrodding at low speeds will heat and kill the oil then after the oils killed then it'll overheat case the oils bad.

All the wrf's,250 426 400 etc. WILL heat up and boil if they are left running without being ridden.They need air to be flowing over the radiator.1 minute can be enough to get them hot if the choke is used.You wrote that this happened after an oil change.Did you previously let the bike sit and run?.Check your air filter is clean as this can enrich the fuel/air ratio and create extra heat.Main thing is ,shut the bike down if you are stopping for more then a very short time.To satisfy yourself,take the bike for a slow ride as it is warming up.It can take up to 1 mile to get proper temp. into the entire motor.Hope this helps

Restarting problem when bike is above temp.


sounds like the fuel is being evaporated by the heat hence hard to start when hot, but when it cools down enough the fuel is not effected, check fuel filter & fuel pump pressure,

OVERHEATING 2000 YZ80


ya i have a yz250f and learned from a first hand experience that any racebike 2 stroke or 4 stroke doesnt like to idle for a few minutes without moviing. i started up my bike and let it sit for 8 minutes to warm up and antifreeze started spewing out. so i cut it off and called a friend that races. he told me these bikes need air moving through them otherwise they overheat easily and the antifreeze over flows because it expands. if i actually read the manual the book says not to let the bike stand and idle for more then 3 minutes cause after that amount of time it should already be warmed up.
so its just the bike over heating and make sure to top off your coolant the next time u ride

Over heating triumph sprite motor cycle 955cc


Sounds like an airlock. When it fell over an air bubble would've gone to the highest point of the cooling system, & when you picked it back up the air gets trapped, if it gets trapped near the thermostat it will send the computer a false reading & fans wont turn on causing an overheat. Give the cooling system a flush. Remove lowest cooling system hose you can find I think its the water pump hose, & remove the radiator cap all the coolant will drain. Put your garden hose in the radiator turn it on & start your bike, run the hose through it for about ten minutes or untill the water coming out of the hose you removed runs clear then shut the bike off. Put the water pump hose back on, clamp it up, & fill the radiator 50/50 water/glycol. Leave the radiator cap off start the bike & get it to normal operating temperature, as it warms up air will rise to the radiator cap & the coolant level will drop just top it up accordingly. Once the bikes warmed up & bubbles stop rising,  put the cap back on & take it for a ride. Hope this helps!
