If its not the valves it could be lean. Is the hot start adjusted right? They mean it when they say check valves every 300 miles on these bikes. I just went through the same thing on one.

I have a 2001 yamaha yz426f that backfires after start and shoots flame from exaust and the exaust gets so hot it glows red.


Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

My VT1100, When first started my pipes get red hot, Why?


Too hot means too lean (lean in fuel). If you have custom pipes you must sync the carbs.

2000 Jeep Grand Cherokee back fire


Backfiring is caused by unburned fuel igniting in the exhaust system, which could be the header, catalytic converter, muffler or exhaust pipe. Red hot is caused by the burning fuel. You either have a timing issue or you are not getting enough air flow into the fuel injection system, which can happen for several reasons. I would try to find a good local mechanic and pick their brain.

2007 yamaha yz450f... while riding last week it was backfiring on deceleration. it blew a 5 inch hole in the header pipe. i purchased a new one, cleaned the air filter, changed the oil and put a new spark...


Exhaust leaks near the exhaust port can draw air into pipe on deceleration and detonate any unburnt fuel leaving engine, causing backfire and high temps.
An overly lean fuel mixture on the engine can make decel backfire worse too.

Wont stay idling and backfires


could be 2 different things,#1 could be the carb that needs cleaned and adjusted( i would try that first,easy.)....#2 valves need adjusted ( is the exhaust pipe getting red hot where it comes off engine?) the factory settings for the valve clearance is 0.04 for intake and exhaust both (with stock carb and head)

Backfiring when throttling back or on over-run downhill


hi,this is quite common on big v-twins,it is normally caused by a leak in the exhaust system(gaskets or clamps)this allows air to enter the exhaust system which then leans out the mixture inside the pipe,when the next hot exhaust pulse arrives from the cylinder,the lean mixture inside the pipe is ignited causing a backfire,check all the exhaust joints and the manifolds,where the pipe exits the cylinder,and make sure they are all tight and leak free,your problem should then go away,but in saying that,you will always get some exhaust popping on most v-twins,hope this helps

2003 dodge 2500 diesel backfires and destroys


Well, usually when a proper running vehicle backfires through the exhaust its caused by an excess in fuel building up in the pipe and igniting. Some newer diesle trucks will spray fuel into the exhaust to clean the emissions and reduce smoke coming out of the tail pipe. You could have a bent or sticking valve that is allowing extra fuel out into the exhaust, or when it went to clean the exhaust (If your model does that) the exhaust might not have been hot enough to ignite the fuel until you put a load on it causing the exhaust temp to jump igniting all the fuel in the tail pipe.

Exhaust glows red


sounds like it's running too lean, could be **** in the carb starving it of fuel. remove air cleaner and spray a bunch of carb cleaner in and let it sit overnight, or take carb off and strip it and clean
