replacing O2 sensor & spark plugs, do I need to have the tps reset? Other recent mods to '99x1: installed forcewinder, wrapped exhaust headers and did not reset tps after making these changes. Getting what I deem to be poor mileage, about 130 miles per tank, is that so bad or to be expected? | ||

No you shouldnt need the tps reset after just changing your O2 sensor and plugs. I have a 2000 x1 and I usually fill up around 130 miles too. My fuel light comes on somewhere between 130 and 140 miles and my butt pain light usually dictates that I stop at 130  | ||

If you drive more like an old lady, you can get almost 180 out of that tank. It doesn't hurt anything to zero your throttle position sensor on a semi-regular basis. It is a variable resistor that moves EVERY time you poke the throttle so it will drift a little bit over time. If you notice your bike surging at low throttle settings, you should probably zero it out. Your O2 sensor needs the exhaust to be bolted on nicely with nothing on the threads because it uses the chassis ground for the "second wire". | ||

"It doesn't hurt anything to zero your throttle position sensor on a semi-regular basis." Your wallet must not be as sensitive as mine.... | ||

I mean like once a season. It's less than 15 minutes of labor. | ||

I bought the software so that I could do mine anytime...if anyone is near and needs theirs done...  | ||

'nuther question: with the bike at operating temp, the oil should just be touching the tip of the dipstick? | ||

If the engine has been running recently, the oil should be about 1/3 to 1/2 up between the lines. After a while, the oil dribbles down out of the tank and into the engine a little. If I'm going on a long trip, I will drive around the 'hood to warm it up and then top it all the way up to the upper level. Mine has always consumed oil a little. Not much but about a quart per 1500 miles. My friend's XB12 doesn't burn/leak a drop. | ||

Normally...I mean according to the service manual, you should need to reset the TPS only when you've replaced it and/or if you replaced the ECM. The function of this operation is just for the ECM to "learn" the exact throttle position when it is fully released. I bought the software to do this when I changed the stock ECM for the race one.
