My '06 TW200 had been "modified" when I bought it, but done very poorly. The air box was butchered to fit a K&N filter on and the poor job led to the intake (rubber from carb to head) being torn. I am returning everything to stock and have a couple of questions about the carb. The one that was on the bike had a few issues. First, it needed rebuilt.....the main needle (the big one in the center of the carb) had a ridge so it needed replace. That wasn't too bad, but when I checked on how much the idle adjustment cable was I about fell over. $59! Anyway, I looked on ebay and found a good carb off an '02 TW200 for $80 and scooped it up. It arrived today and everything looks exactly the same except the numbers on the side of the carb. My original carb has the number 5FY1 10 1A20 stamped on the side with the choke button. The carb I just got has the number 5FY1 10 1F30.
Does this difference in numbers mean anything significant? I'm guessing the last 4 numbers are a date stamp, but maybe someone on here would know for sure.
I opened it up to check the jetting and it had a 126. Since my TW has been rebuilt with a TTR225 head, piston and cam I figured I'd go with a 130 to give it a little more fuel than stock. Does that sound like a likely assumption?
Finally, on the carb there is a black hose nipple on the same side as the choke button an inch back from the choke, just above the fuel line inlet. On my bike when I bought it there was nothing attached to this, which I thought was crazy so I capped it. It didn't seem to affect anything with the way it ran but it didn't seem right to have an open port. Anyway, on the new carb there is a 1 foot length of hose connected to this nipple and it looks like it is supposed to connect to something. Does anyone know where that hose goes to? I appreciate all the assistance. I love this bike, and I'm sure it will be even better once I get it fixed correctly.
