Hi, I am writing because of this: http://www.badweatherbikers.com/buell/messages/32777/127636.html?1145899947 And thanks for answers. I lost my license for a while after last post. And then came winter here in Finland. So have not been able to ride for a while. I am posting because this problem described above still is not solved... After winter the bike was ok again for some time. I got race ecm and jardine installed and the bike went totally crazy in positive way. Then again performance started to suck. The bike runs basically ok, but just has not the "beast" in it.. Here are the symptoms: 1. Poor idle running when engine cold 2. poor fuel consumption (5.5litres vs normal 4.5 per 100km) 3. More backfiring (you notice this with Jardine easier vs stock muffler) 4. Poor performace generally (does not rev well, no grunt) 5. Sound is not as sharp and loud as normally (this can be noticed also easier with jardine) I think this cannot be because of mods. This occurred also before. Now the performance difference is bigger than normal. Symptoms could be because bike runs too rich air/fuel ratio? If so why.. I was wondering could it be: 1. broken/dirty O2 sensor 2. TPS problem (this was adjusted at local dealer after installing race ecm and some time all worked fine, not anymore. BUT there was not any error codes??) 3. Some other sensor Hmmm. It now popped to my mind that it was before first wash this year when all worked fine. Could it be that there is water/humidity somewhere that causes this. Maybe in O2 sensor (btw where is it located?) I am not sure about this wash thing because it is hard to tell excatly when symptoms start. Thanks for answers in advance! | ||

It's possible your dealer screwed up the TPS reset. | ||

Can TPS reset be screwed somehow? I am not familiar with details how it is done. Bike was ok few hundred miles after reset. | ||

If they do it wrong then it might do what your saying. Just a guess being you did have that done. I like to start at the simple stuff and work my way out. | ||

There is also a possibility you fouled a plug(s). I would hope they gaurantee their work though and check to make sure they didn't do it wrong. If it's not the case, check those spark plugs. | ||

the difference between the tps being out a hair and just right is night and day on my bike (12r). some are more sensitive to it than others, and yes they do seem to move around a bit over time. just get the software yourself or look for a badwebber who has it locally and do it yourself. once you understand what is happening it will make sense to you. | ||

Poor idle, increased fuel consumption and popping through the exhaust could indicate an intake (vacuum) leak. Wouldn't affect high rpm running as much. The TPS reset or fouled plugs seem more likely. Good luck, Bill | ||

Thanks for answers. If the problem is in the plugs, wouldn't the engine run crappy (unstable)? I do not know english word but I mean that there would be misfiring etc. Now engine runs smooth... Or could it be that spark is not strong enough to burn all the gas?? Then plug problem could make sense. I called to dealer today and he thought air intake leak. This has sometimes happened to his customers. He has time to check the bike after a month so I'll have to try first myself  I'll decided to put original airbox etc back and I'll see if there is increase in performance. This way the ecm should make a/f more leaner I think? The next step will be plugs anyway. I'll post what happens. | ||

I would get back to the basics first... Plugs and wires, especially if humidity might influence it. Bad wires like to send the spark everywhere else than the plug when it is damp, especially under a load. If your plugs are worn than this problem is even worse. A bad plug could also work fine at idle and then screw up when you put a load on it. I would do this before you try anything else. You have to have a good starting point. New tune-up parts should always be first in my opinion. | ||

Thanks Mkenn!  Didn't know that about plugs. I thought they are on/off. I'll have to buy them right away. I'll get back soon (Message edited by bandit_jr on April 25, 2006) | ||

Now plugs are new and torque is back! YIHAA!!!  There are some problems with plug wires, I think. They looked surprisingly f****d. Any recommendations for new ones? The original ones were terrible to work with. Espcially the back one. So looking for something that is easy to fit and take off. |
