Question about 2003 Triumph Bonneville America

1 Answer

Backfires Hey all, just as the subject heading says: My 2007 Bonneville has been running perfectly. (well except that I have to switch to reserve at 106 miles versus the 125 everyone else is getting)...I'm just hoping that its because I'm still breaking in the bike considering that I only have 1300 miles on it. Anyway, whenever I shut off my bike, I hear a single backfire. The bike is completely stock. I'm curious if this is normal or something I should be concerned about. If its of concern, what may be the possible problems and how to fix it?

My '06 Bonneville America also often emits a single, very quiet backfire right after I turn it off. It doesn't do it every time, but approximately half the time. As with yours it runs beautifully and, therefore, hasn't been of concern.

Backfire is a problem? I like it!

If you don't you might want to first check to make sure the exhaust headers are properly tightened to the head. Replace gaskets if needed, as exhaust leaks can cause this. Another potential cause is an over-lean pilot circuit. You might need 1 size bigger pilot jet.

Bubbles in overflow tank


Hello --
well -- was the head gasket mechanically or chemically repaired? -- If cemically, you may need to go to the other side and remove/ replace the gasket..
you may need to run the vehilce to "burp" out any further gases remaiing in the coolant system, esp if it was not completely drained and had some air pocekts in there somewhere..
Best regards

Ford Focus 2005 - cold start backfire - runs great after 5 mins, when hot


White Smoke out the exhaust, is usually a sign
of coolant & most likely the start of a bad head gasket

At this point your use of the car should be curtailed,
to prevent any further damage

You should not use the car at all, until all issues are
diagnosed & resolved

2007 yamaha 350 raptor will only run on reserve


ive herd that some bikes have to be maintenanced if they run out of fuel while on reserve. I would check the owners manual for the reserve tank and see what needs to be done.

My 86 suzuki intruder 700 backfires out the exhaust at idle. and makes a tapping noise. i already did a valve adjustment an new plugs


It could be the speed of one carburetor is faster than the other. This causes the backfiring as well as forces one cylinder to run lean which causes the tapping noise. You will experience an identical tapping or "ping" when you get close to empty on main fuel and need to switch to reserve. Most likely you or the previous owner unknowingly adjusted the speed of the rear carburetor down because of the high stock idle not realizing the front carburetor needs to be slowed down to match. While running simply turn the idle adjust screw clockwise on the rear carburetor until the idle smooths out and the backfiring/tapping stops.

1998 Pontiac Bonneville SLE will turns over but will not run


I would check to see if the spark plugs are fouled. Or you might have a bad ignition control module (mounted under the coil packs). Auto Zone can test the ignition control module.

2006 Bonneville America electrical failure


To start with, your battery was probably already low. You have to be at about 4000 rpm for the charging system to kick in and put out 14v or so. So if you just sit and idle, you will eventually run the battery down. If it is already low, you may have run it down below where there are enough amps to start it again. I know my 2002 BA started having what appears to be charging or regulating problems and the batteries won't stay charged. Try charging the battery with a good trickle charger to begin with. Then, when it is fully charged, run the bike and see if the charging system is keeping things up.

Cutting out, choking, dying totally, won't start


I am no expert just a VTX owner myself.
If it is not the coil, make sure your negative ground on the battery is screwed down tight. I use a product called "seafoam" to clean my fuel system, plus it also removes carbon from the head of the pistons.
Hope this helps.

Running rough and backfires


Yes tht could be the carburator since the dirt / fine rust tht settles at the bottom of the tank has found its way in to the carb.
Clean the carbs. and replace the in-line filter.
Water in gas could also be it, since water floats and you had reached the gas to reserve the water may have found its way to the carbs and thus the rough running and back firing .
