I can't get my carb's tuned properly with exhaust and pods. ):

Hold on (I didn't read it all to see if you said what pilots you were using)! You want the air bleed holes. You want to be using Mikuni BS 30/96 pilot jets. They have 6 holes on the sides in a 2-1-2-1 pattern.

You say in a 2-1-2-1 pattern... :/

THESE are the jets currently in the bike, 2-2-2-2 pattern, they SAY they are mikuni, are they imposters?! haha

Look at the 3rd post, the UK chart.

HA ha ha ha........nate hates this chart but I don't care.....

With a quick look through I didn't see anything XJ Maxim specific... :/

!!!

OH MORE INFO!

The reason, I personally dont think that only one size over stock on pilot jets is going to cut it is because:

1. when I had smaller jets than I do now, pilot fuel screw had to be out 5-6 turns to run ok (stopped and revv'd)
2. with current jets, pilot fuel screw still had to be out 4 turns to run ok (stopped and revv'd)
3. with current pilot jets screwed down to 1 turn out, the bike doesnt even want to start.

To ME that means I need even BIGGER pilots... but I am not very knowledgeable with motorcycle carbs, as these are actually the first I've really messed with!

He is wondering about the pilot jet size.

Although knowing the mains for sure is helpfull as well thank you!


If someone KNOWS for sure the stock pilot jet size and also thinks that only going 1 size above that is good for pod filters AND open headers, let me know!

THANKS!!!


You guys are awesome.

I didn't expect so much info so fast.
This is only the second forum I've ever joined (strange for a 5 year comp. tech.)

The other one was a Yamaha FZR forum!

I've usually always found any answers I need from just browsing various forums.

Stock main jetting on the 1100XJ is 112.5's across all four. Anyhting else, clymer's or otherwise is another urban myth.

BTW, the difference in main jetting on the XJ and 80-81Specials(110's across all four) is dictated by metering rod differences. 80-81Standards used even different metering rods, so main jetting was different even yet. 78-79model carbies were all the same for all models(only two), but also fed from both pilot and main circuit thru ALL rpm ranges, which seems to allow a bit more error and ease of tuning. The later carbs seem to be a bit more fiddley with circuits seperated more. Either way, patience, persistance, listening to experience here and not trying to re-invent the wheel is key.....grasshopper.

That is WONDERFUL information to have! No wonder they are easier to find than the non bleed... -_- do you happen to also know the exact stock jet sizes for the 82 xj? That way I can order one size up from that...

Sorry, an urban myth at best.[/QUOTE]

+1 to that!

The ones with the holes, the BS 30/96 pilot jets, ARE the stock jets. If yours has the no hole jets in it when you took it apart the someone else put the wrong jets in. Some of the kits even come with the wrong jets in it just because people don't know any better.

See?! I keep getting thrown in loops over this! Hahaha
No, just tryin' to getcha' squared away.

So, WHY, are the bleed type better than the non bleed which were stock??

Not better, just correct for application as opposed to the VM style pilots.

Vacuum synching will only matter at low throttle openings.
