CRAPPY MPg?!?!?!

Greg,

I think what 81XSProject was referring to is that MOST of the time, all the jets are still in decent shape and will run as good as the new jets will when cleaned up.

For folks like me that either did know any better or in the second go around needed new jets as the old ones were all the wrong sizes, the kits can work out well. But, you have to know what jets you are looking for and ASK ALOT OF QUESTIONS before you buy. There are several different styles to the pilot jets and every one of them will screw into the carb just fine and may even start and run in there, but will decisively F-up the mixture badly. I have seen this several times so far in person and read about it to many to count.

If you just need a couple parts, you can buy the genuine Mikuni jets for about $6 a pair and the mix screws aren't much more which is ALOT cheaper than the kits.

ok so, local repair shop quoted me $500 labor to clean and sync the carbs!!! wtf that's nutz. I'm mechanically inclined, but don't have the knowledge /tool/or work area to do this, any suggestions?

A 20" box fan, $110 for a four gauge sync tool through ebay, and about four hours of time is all you should need. It's NOT ROCKET SCIENCE!!! I should know, I was doing neutron beam testing in my last job! The carb sync just takes time, and that is what you are paying the shop for, at about $85 per hour!
The XJ WILL need the YICS block off tool. You can look up the tool with a search here, and pick up one for about $100, or build your own for about $15.

Actually you can get the sync tool for less than $50 on ebay. I got my dial guages for less than that and IIRC the mercury sticks are even less, and someone on here got a set and is pleased with them.

I'd trust this member's work better than my own.

I hear that guy does good work. To keep beating my cheap drum you can also make a great sync tool for under $15 out of vinyl tubing and a little vacuum line. I believe it is in the tech tips.

i realized, i had noticed that the oil level was low, so i added a quart... i now realized it was on the side stand. the video, the bike ran fine despite the noise and that was after the crash....
i read on here that idk the oil level is to high some oil might be sucked into the carbs and cause my problem, running too rich... what do you think?

[81xsproject]

I don't think one quart would do that. It could...I guess. If you are running too rich on an XJ, I would guess; float level, improper jetting, junk rebuild kits, idle mixture setting (though this really only affects the very low end of RPM range), or maybe leaky float valves. Most issues with dirty carbs result in too lean.

so today i was leaving work, it was cold out, started the bike on the sidestand, got a bit of white smoke.. only out of 1 pipe, *the one that hit the ground* as soon as i sat on the bike and leveled out the bike smoking went away?!?!

[tbcfreerider]

so i looked at my air filter and its dirty with a bit of oil on it... any thoughts?

Texas Tea?

If your air filter is made of paper then likely you can't clean it well even if you blow it out with compressed air.

The air filter I use is made of a wire mesh frame with a foam cover. This foam cover is removable/washable. But before installing it again, the foam has to be sprayed with a special oil in order for it to truly filter the air like it is designed to.

So for me, having oil on my filter is normal.

The engine is an air pump and if the filter is XSively restricting the air flow then your MPG would suffer.

The crankcase breather tube connects to the airbox. If you overfill the crankcase they can puke oil up the line and into the airbox where it can get on your air filter. Oil level should only be checked on the center stand. Or it could just be an oilable filter as Larry suggested.
