Question about 2008 Yamaha MT-03

1 Answer

Heat questions heat from the exhaust. The rear header pipe is in very close proximity to the shock. The front header pipe is not far from the oil tank and oil coolers. I don't care for the looks of header wrap, but I don't want to heat up the shock either. Thanks.

The shock would get just as hot without the exhaust being next to it. The amount of heat generated by the thousands of up/down cycles a shock goes through, especially at racing speeds, is higher than the heat transferred from the pipe being next to it.

Harley-Davidson exhaust pipes too hot(low rider 2016 s).


Hi, Lamont some brands of motorcycles will have exhaust discoloration right out of the gate when brand new due to engine design and the quality of the chrome plating. These bikes will also have chrome heat shields to prevent burns from accidental contact and hide ugly exhaust discoloration. Some manufacturers go as far as having heat shields on mufflers. If you purchased a brand new set of chrome aftermarket mufflers or a complete exhaust system only to find excessive bluing on the headers and golden and sometimes blue areas on the mufflers appear after a few hundred or so miles of riding your first impression is your exhaust is running too hot which must mean so is your engine. Wrong! exhaust discolour is caused by 3 different things.
1. Poor quality chrome plating, usually dictated by the price of the part.
2. Retarded ignition or cam timing caused by improper installation or a faulty CPS, CKP, MAF, MAP sensor.
3. Mufflers discoloration is caused by an excessively rich fuel condition.

What will cause bluing on front exhaust pipe on 2003 yamaha v-star 1100


Ronald, All stock single wall pipes will blue some time or another. A big cause of Bluing is a badly tuned bike, burning rich or lean putting more heat into pipe.
There are polishes available to remove the Bluing, and some people on forums, they suggest to remove and with high heat paint, put several coats inside of chrome pipes.
Check the attached links,instruction and guides, Good luck

To install a 2008 touring starter FIRST verify that the two ring dowels are installed in the primary chaincase (or starter) flange, lubricate the o-ring on the starter and lubricate the bore of the primary chaincase with a light film of clean primary chaincase lubricant, carefully slide the starter in through the space between the rear exhaust header pipe and the side cover and with the starter solenoid connector at the front, move the starter into its installed position, remove the shop cloth or towel covering the oil fill spout and install the engine oil filler cap/dipstick at the top of the transmission case, install the slot of the exhaust support bracket onto the stud of the bracket tab aligning the other holes with those in the starter flange, start the Keps nut onto the stud, engage the hole in the exhaust support bracket, install the starter front mounting screw with captive washer, install the starter rear mounting screw with its captive washer and alternatively tighten the starter front and rear mounting screws to 25-27 ft-lbs (33.9-36.6 Nm), tighten the Keps nut on the stud of the bracket tab to 12-15 ft lbs(16.3-20.3 Nm), install the main power and battery positive cable ring terminals onto the battery positive post, install the hex nut and tighten it to 70-90 inlbs(7.9-10.2 Nm), pull down the rubber boot over the terminal connections, install the starter solenoid connector at the front of the starter, if removed, install the three worm drive clamps to secure the heat shield to rear header pipe, tighten the clamp screws to 20-40 inlbs(2.3-4.5 Nm), insert the bolt through the battery negative cable (black) into the threaded hole of the battery negative (-) terminal and tighten the bolt to 60-96 in-lbs (6.8-10.9 Nm) and reinstall the seat.

Where to fill transfer case


HI. On the strat the fill plug is just behind the rear exhaust pipe about one inch or so to the rear. You need to loosen the front exhaust header nuts (don\'t remove 17 ft. lbs. ) remove the rear header nuts (these are allen style 14 ft. lbs.) pull the rear header out of the exhaust port. Use a torque wrench or they will leak. Now you have enough room to install the allen wrench into the fill plug. This plug is about 1 1/2 in diameter. It is a big pain to do. Don\'t loose the exhaust gaskets or just buy new. They are about $12 each. I have reused them just a couple times then install new.

I just install new VH slip on mufflers and now the front exhaust pipe is hoter than the rear, also smokes a bit by the connection from the heat. What's going on?


Not expert with newer hogs but the pipes should come with reset data for your computer so you can dial in the recommended fuel/air mixture to mqatch the new exhaust pressure.It might even need new heat range combo's in plugs.Get manufacturer's spec and programer.Good luck.

What tempature should my rmz 450 run at? Also why does my header pipe get red hot after running for only five min. at idle?


The cooling system on the RM-Z450 was designed for motocross and only works efficiently with air flowing through the radiator. You should not sit at idle for more than a minute or two if at all possible. The extreme high output of this engine causes extremely high exhaust output temperature. The pipe temps can reach 600-800 degrees F plus all the way back to the silencer. This is normal on all modern racing 4-strokes. There are a lot of aftermarket products available that help increase the cooling system efficiency. There are also several products that help insulate critical areas from engine and exhaust heat including shields for fuel tanks/lines, the carb/throttle body, rear shock, and plastic body work.

HEAT DISCOLORATION ONLY ON FRONT EXHAUST PIPE NEAR HEADER. WHY IS THAT?


My experience with this is limited. The fix then was to rejet the carb and remove the blue with special stuff they happened to sell in the parts department. The trouble was, as was explained to me by the mechanic servicing my 1973 Honda 350, too much heat because of too much fuel going through the carb.
