Its a motard so why not toss the airbox and go with a pair of Uni's and be done with it?

edeher · 08-04-2009, 06:20 PM

Because one im thinking the unis will get wet whenever it rains...which is alot in FL. and two im trying to get it close to stock to get it to stop popping on decel. so im thinking hooking it up to the stock airbox will richen the mixture a little.

Are they vacuum lines, or are they just vent tubes?
If theres no vacuum there, you could get a fuel filter a 1" line and T and zip tie it up under the seat.

As far as water goes, if you're using good oil it will deflect most of it. you could also use heavy vinyl and protect the extended filters that might stick out of the frame.

Did you try running the fuel screws out? 3/4 of a turn out is too little. 1.5 to 2 is normal, less or more it needs a different pilot jet.

edeher · 08-05-2009, 04:34 PM

yea once i get the airbox connected so the mixture will be stock then i will try putting the fuel screw at 2 turns out. I just think that with no filters connected it made it very lean with all the air coming in. When i used to work on scooters if you disconnect the air box the bike would bog really bad unless it was jetted, this was on two strokes but im sure it is doing the same thing.

Pure teflon? You don't need teflon. That's shit's expensive! Only 200 deg F also.

12" of hose for $127...

Many other options.

edeher · 08-05-2009, 06:14 PM

ohhh that explain it....didnt know it was tephlon. i think the reducer hose from ebay should do it

Uncle Conan · 08-06-2009, 09:25 PM

FYI, My brother checked on Jetting for the stock carb. There are some that are different side to side. Air jets, and mains. I think due to the intake port difference. I would make it match the left side to start, and adjust from there. There is a crossover from left to right, but the center and right intake are fed from the right side, while the left gets charge from the left side. Hope this helps. When you get it sorted out mine will be easy.

edeher · 08-09-2009, 12:52 PM

i dont think the second carb has a pilot jet. i took them apart and the first carb has a 22.5 and the second carb doesnt have one, not even threaded so i dont think it carries one. I need to go up on the pilot jet for sure because i am still getting poping from deceleration. And i have to go up on the main as well because it will cut off after a 2 minute straight run, i think it is running out of fuel. Anyone know the main jet size?
