Hey all

Well i've finally got off mah ass and decided to give my baby a tuneup.. she's been running a bit rough lately..

I've taken the tank off and I'm wondering where the vacuum hoses connect from the throttle synchroniser connect with the throttles??
and where are the adjustment screws?

I thought on a fuel injected bike it was all done inside of the ECU accessed by Triumph's proprietary tool.

When you take the air filter off you cant miss the sync screws, they are located between each throttle body. Same as on carburated bikes. You connect the balancer to the IAC nipples.

Vonbons, throttle injector pulse and spark advance are the only two variables that are controlled by the ECM. You still need to balance the throttle bodies from time to time, rarely but they do need to be done.

does all of this apply to the 2002-2004 models as well? My mpg is right around 40 which i think is low. I just did the plugs, air filter(K&N), had the bike re mapped for the two brothers exhahst, and did an oil change(mobil 1). I thought that covered a basic tune up. So if my bike has 10,500 miles on it would this balancing be an issue?

hey.. thanks for the replies boyz :-D
i've found the IAC nipples to connect the vacuum gauge into

But I can't seem ta find the last adjustment screw!
I found one, inbetween cyl 2 and 3, which uses a 6mm hex key :???:

does anyone know where the other adj screw is?

Ben,
I had the airbox off this weekend and looked up the adjustment screws in the manual...for a 2003, don't know if yours is the same?

John,

Good photo. Everything will be the same for '02-'04 model. Don't know about the prior versions.

Trafficfixr - my experience is that 40MPG is OK if you're mostly in low gears and constantly off and on the throttle, i.e. in the hills or battling traffic. But for touring on the open road, you should be getting closer to 50MPG.

Cerberus

if you are at 10,500 miles then you are coming up on a major valve adjust interval, and the TB sync should be done AFTER the valve service, not before.

granted, different bikes, but if i get better than 34MPG i'm happy

pre 02 bikes only have two adjusters, as one body stays stationary and you must match the draw to that.......the real new bikes like the R3 can be balanced through the triumph handheld.

I know this is an old thread, but I thought I would tackle my throttle bodies this spring now that I am digging the bike out of hibernation.

Just wondering what tool you guys use to do this adjustment? Is it possible to just use any of those mercury types that are out there? Does it have to be the fancy Triumph gadget?
