Hello there ... Well you got me confused ... What exactly do you mean by saying back firing ? If you hear some noises from the exhaust and seeing flames now and then you must first check your carburetor . There might be something inside blocking the way , then you must look at the carburators neck ... Check for cuts or possible air loss same with the air pump... After that you can check the exhausts for any possible holes on the front neck or somewhere after the neck ...is the sound of the bike any different ? Check the chain also you could need some tighten if that's the back firing you mean ... I hope I helped !!!!

    Spark check and replacement first !!! And then check the carburetors ...I just read your problem again it must be sparks and air filter ! Check these first and replace your old engine oil and if the problem continues check carburetors for possible air failure ! If this won't help check the engine and transmission kit for possible failure to a mechanic

SOURCE: bike keeps back fireing when first starting

Hi and welcome to FixYa,

Initially, backfiring is a spark/timing issue or contaminated fuel (water) or as you stated stale fuel. AVGas would not result to backfiring but rather a stronger pull though would heat up easily.

Good luck and Thank you for using FixYa. Happy Holidays.

Pls be informed that due to my current rank and rating, even a Helpful would be detrimental to my status. Should this solution not address your concern, it would be appreciated if you could just not rate it at all. Cheers.

Your timing is off. Try backing the timing up to 4 degrees before top dead center!

SOURCE: bike is starting to backfire (more of a burp) at

Chances are you just need new spark plug caps and new spark plugs. Modern resister caps burn out periodically or the get corroded (I have heard of people unscrewing and taking out the inside resister and cleaning off the corrosion). Some times the cap is part of the wire (about$40-$50 dollars each) But you may be able to replace the "NGK caps" for about $5 each( clip the wire and screw on the new cap). This is cheap and easy to try and will usually fix the kind of miss you describe.

This is a common problem related to plugged or very dirty low speed idle jets in the carb, When they get that bad it is best to have the carbs cleaned by a reliable mechanic.

Back fires at 2000rpms left pipe only


If you're running stock pipes, the rear pipe splits.
Half goes to the left, the other half merges with the front going out the right.

You state just the left pipe "pops", so the first thing to check is for an exhaust leak on the left pipe, starting where it splits and working your way back.

Backfiring and trouble starting


If you change the exhaust pipes, you have to sync the carbs (if you cant sync them, you have to change the carb jets), usually it is backfiring because the carbs are not in balance.

I have value train niose in the front head 2002 low rider is this normal


Depends. You will get some valve noise as the bike gets older, however, this noise is only noticable at Idle. If you are getting a loud enough noise at crouse speed to the point of being annoying then the chances are you have a lifter that is starting to collapse. This is upper end noise only. If you are getting a lower end noise and have at least 30,000 miles on the bike. Chances are the valve drive chain tensioners are going. This is a known problem with twin cam engines. I have two twin cams and had to replace the tensioners on both. My advice to you if this is the problem is to go to Gear Drive cams. I did it without any regrets. I have a quicker power response and was able to increase my rev. limit speed by almost 200 rpms. The down side according to some is a wining noise. I don't get any noise I can hear over my Python 3 pipes. In my opinion the benefits out weigh the noise. Without having the bike in front of me this is the best I can suggest.

First off - Did you take the whole front end off to install the lowers? If you did - did you tighten the Main locking washer on the uppper triple tree to the correct specs? You might want to raisee the bike off the ground with a scissor jack under the frame and then with someone holding the bike steady see if you can move the front tire sideways or up and down. This is will tell you if that locking washer is loose or maybe a bad bearing in the front end triple tree

SPUTTERING WHEN HOLDING 50-60 MPH


Since it ran fine before you "fixed" it, go back over the things you changed. Put the old spark plugs back in it. Double check all spark plug wires and ignition connections. Put the bike in a dark area and run it at night, can you see any arcing anywhere?

Stage 1 Low rpm backfire


If you are running straight pipes they might not give you the right back pressure. This can be reolved by either going back to riginal pipes or instaling a bolt into the pipes about 5 inches in to make back pressure. Another thing? Did you have the bike's electronic ignition reset after you messed with it?

1994 9000C Runs hot


Could be the fan thermoswitch. The thermoswitch, if there is one*, is located on the lower portion of the radiator just in front of the turbo outlet pipe. Here is a picture.
You may also have one of the fan relays failing. (On some cars, there were two relays, one for low speed and one for high). Here is a picture.
For general diagnostics of the cooling system, go here.
2 stage cooling fan wiring diagram here.
This also will tell you where to find other components to check, like the fan speed resistor, and provide other diagnostic checks.
