CARB IDENTIFICATION

[Gix]

Looking at buying some new Ti needles and emulsion tubes and was told there are two types of carb for the TRX
Mine is a UK bike registered in 2001.... is there an easy way to identify which carbs I have without stripping down..I can't seem to find the ident marks
Thanks in advance

Go to the downloads section here and look at the repair pdf, their `type` is listed there.
had a quick look:

Mikuni BDST38/2

I don't believe that is correct. AFAIK the carbs were common to all models

Isn't it the TPS that switched from one side to the other?

I don't doubt you but this is what is on the Factory Pro webite

''The internet's #1 choice.
"TDM / TRX Ti ProKit"

This is "the" #1 jet kit choice of TDM riders.
Best lowend and midrange and the best, if the user / tuner tunes for it, mileage.

Uses Titanium needles. Adds more low-end / midrange, if the proper main jet is selected, more topend power. Easy to install and tune - no slide drilling.

Make float height setting easier! Pick up a Float Cage Holder for Mikuni 38mm carbs - Click here

Note
If you have a 1999 model with 40mm carbs, marked; Type BDSR38, id, this kit will not work -''

True dat, 99 the TRX got a tad bigger carbs and 3-4 more ponies.

Blimey - I never knew that. Thanks KW

That's news to me, very interesting. Are they better than the originals? Might be a cheap upgrade between stockies & FCR's if so.

The Japanese home market ones had different carbs with accelleration pumps - did they use the same tubes/needles? I'd guess there would be a different taper to accommodate the extra squirt from the pumps

I have a set of carbs here from a Japanese model. Indeed they have something that looks like accelleration pump jets.
I will put them apart later on to see jet sizes and that kind of stuff.

Mine is a Japanese import and has accelerator pumps, and I fitted jets and needles for a later model Aust bike, if that makes sense.

BDSR type 99-00 (and also TDM to 02 i think) should be same as carbed R1´s...found a jetting sheet 147,5 main instead of the 142 on BDST.

I don't think the TRX changed but the TDM certainly changed the carbs/gearbox ratios in '99. In fact, the post '99 emulsion tubes on the TDM can't be changed - can someone verify by part numbers that the TRX carbs changed then too???
