just wanted to say thanks for the video and quick responce to my question. i followed your steps in the video. and the bike sounds damm good. starts right up... thanks....thumbs up.
Oil Filled gauges are much better than the cheap ones I got .... but also you can do it by ear with a tube to your ear down the air filter intake side of each carby ... you can hear the different speeds of air rushing into the venturi
Really helpful information for presetting the carbys before final balancing with gauges, thanks mate. One tip for building your own vacuum gauges, use some in line ball valves and slowly close them to a point while running until it evens out the bouncing of the needles to get a more accurate reading ;)
Or cut the vacuum tubes about an inch from the end you plug onto the carbies, and insert a small section of brass tube with small bore to restrict the airflow, that will damp the needles too ;)
I am going to attempt a carb clean and balance very soon. Where exactly and how do I hook up the tubes to my vacuum gauges for balancing. I have a 2001 triumph triple 900 with, I believe, Mikuni carbs.
Hey! I have a similar Mikuni carburetor on my '95 Tiger 900. Lately had some issues when it suddenly decided to only run on two cylinders. Noticed today, when i changed throttle-cable, that only two carburetor open half way, the third one is completely stuck! Do you have any idea what the issue might be? Any advice appreciated! Thank you!
dude the fuel and overflow lines, I took my carbs off so long ago I can't remember the route they took any way you might still be able to get a shot of that?
T900 here. Legend looks the same. Question!, where the two additional hoses on the carb should go ?. I rebuilt my carbs including new rubber carbs to head. Synced them as much as possible with current issue. Problem is that is not stable in low RPM and it reduces high RPM very slow. Similar to air leakage behavior. My two hoses are open. When I close them, low RPM is stable but I can't put high RPM at all, it shuts off. Another Question. I know, there is a CAL version, my is not, but I still have the hoses. I know there are to collect petrol viper, but like I mentioned my version is not CAL and has no additional plumping. So, what;s the deal, should they be closed or open. Looks bad ether way. Also, why they take the air in and not through the air filter box ?
+Michal Augustyniak You must eliminate the ending itself first.... if the engine is not ins good condition ... no Tuning will get it right. Valve Adjustment first => Compression test => Ignition system Check => then carbs. check for vacuum leaks etc.
+Jim Trotter yep..... you can also do it by ear once you have the basic setup done.... (mechanical setup) you can use a tube and place near intake venturi on each Carb and listen for the change in suction sound to adjust the other 2
My Mate just did his Legend 900, following my guidance and also buying these: www.ebay.com.au/itm/Fuel-Vacuum-Carburetor-Synchronizer-carb-sync-Gauge-GS-CB-KZ-XS-550-650-750-850-/221419014072?hash=item338d9a07b8:g:dqcAAOxyhXRTKA5Z His economy from 8.7L/100Km to 5.6L/100KM Needless to say he is really stoked!
My 2000 thunderbird is almost ready just got to set the vacuum on the carbs. Your video helped a lot. thanks
Thanks for the great vid! Getting my Thunderbird Sport ready for summer. Now I need to check valve clearances. Have you done a video on that?

Hey There.... that is a really good idea! Thank you!

Excellent guide.
excellent tutorial, thanks
2Wheels1Nut thanks for the feedback.

+Daniel McDermott I would like that shot too.
what is the vacuum pressuer on those triples, I got the same kind and cant find nfo anywhere
not about the pressure it is about Equal balanced results

+Michal Augustyniak One more thing, I decided to rebuilt my carbs just because of this issue. There is no change after all, at all :(

+How To - Westy Style! Yeah, that's all done.
you must have a vacuum leak then .... no other reason.
i think uour talking about the choke tubes on each side of the center carb.
i have a 2000 triumph thunderbird 900 with 3 carbs. is the balancing procedure the same. the carbs look the same as in vid
+Jim Trotter yep..... you can also do it by ear once you have the basic setup done.... (mechanical setup) you can use a tube and place near intake venturi on each Carb and listen for the change in suction sound to adjust the other 2
+How To - Westy Style! will it still work the same if you bypass the emissions. i am in cali.. and the bikes emissions have been bypassed.
Does anyone know the factory setting for the pilot jet (screw)?

Thanks for that

This is why I avoid carbs jeez
