Any Carb Guys

if I can pick your brain my 2001 Triumph Adventurer pisses gas if the petcock is left on so I am doing an overhaul I see a kit on ebay it looks like what I need but it says from vin # 62507 on and my last five are 16015 will this work?
Triumph Adventurer KEIHIN Carburettor Super Rebuild Kit (Qty 3) l
Did they have different models of keihin carbs? finding it hard to find rebuild kits for this carb.

Sounds like the float is stuck and just needs to be cleaned. Unless you jack up the bowl seal when you take it apart a rebuild kit is probably unneccessary

BTW...I am not an expert but I seem to be working on carbs every other day lately

Let me tell you about Suzuki Intruder carbs....they are a mystery. Properly synced they work fine, and won't give a minutes trouble. LOOK at them and they might go wonky. Funny thing is most Intruders will sort of run no matter what shape the carbs are in. In good nick they get out of their own way. Finding someone who knows how to sort them is a skill in itself.

Definitely what @R3Tex said , more n likely the float stuck or a bit of crud in the float valve allowing the carb to overfill and dumping out the overflow !

 

[VABird]

Agreed, likely a stuck float. Take all 3 apart and clean-clean-clean!
When you put them back together, here's a great kit to help sync them and stainless allen head screws to replace those stripped phillips heads.
I had similar on my Legend TT & worked very well.

My idea didn't work? Is it not a vacuum operated petcock?

 

[scot in exile]

Sorry Paul I just saw your reply, it is not vacuum operated.
Did Triumph use different Keilin carbs for different years? as I said the kit on eBay said for last five of vin#62507 and on, my last five are 16015.
I will clean the hell out of the three carbs and change the oil and filter hate to have gas in the crank when I go to start it.

Altho always a good idea to change oil and filters on a bike that dont get used very much you shouldn't have an engine full of fuel due to a misbehaving carb ! The fuel level and overflow are both well below the inlets to prevent this happening . With a well functioning carb , a small amount of fuel is bypassed thru the carb via the starting circuit
to start the engine , and once running most modern carbs have a small mechanical pump connected via the throttle linkage that mists a metered amount of fuel into the carb venturi where it is mixed with induction air and sucked into the engine . More traditional carbs have a tapered needle which rises and falls via the throttle linkage into a main jet allowing fuel to be sucked up around it on demand .this happens when you twist the throttle and before that fuel into the engine is controlled by the pilot jet and slow running or idle circuit ! All fuel within the carb is controlled by the float and float valve and kept from overfilling due to problems by the overflow pipe . Sometimes a good clout to the float bowl on the bottom of the carb is enough to free a stuck float . Old fuel and crud can be drained via the plugs at the bottom of the carbs negating any need to take anything apart ! I am certainly not a keihin or mikuni trained expert , just imparting experience from owning many motorcycles over the years !

Agree with Nat somewhat...on Mikunis anyway. Majority of yoir ride is governed by idle circuit and pilot jet. The fuel/air mixture screw in most Mikunis is usually the culprit for poor idle and bogging down as it is a fixed neexle and seat arrangement that is easily clogged by varnish, trash, etc. If you do take it apart. Turn the screw all the way in while counting the number of turns prior to disassembly. This gives you a starting place when you reassemble and start tuning. Never had to deal with balancing three carbs before but I use a simple manometer ( clear plastic tubing taped to a yard stick) for balancing dual carbs. Of course this is all probably useless information since you are dealing with a different carb and more of them...good luck!
