Thought I'd throw up some photos of the mk2a carbs (BDSR38's) internals as one or two peeps were/are curious to know how they differ from mk1 and mk2 wans.

I guess, in a nutshell, they're virtually totally different carbs ! And they seem to be made to last a lot longer as most of the plaggy bits are now brassy bits



Even the choke plungers are brass......oooooooh !



They're deffo a much better quality carb, even if the toobs are kinda permanent.

Nice wan SR. Does the tube type permanent area look replaceable?

[Skidders]

Mk2 A ??? is there a 'B' 'C' etc and how do I tell whch I have SR ?

Nope, I don't think it's replaceabubble Dappers. I'll email ya sum photolerios when I take a few more My flickr foto account is nearly fulled up

The mk2a is the 99-01 model. It has a fuel gauge where the temp gauge used to be, hazards, anna digi trip meter amongst other fings.

so them th'imulsion toobs go through the slides? well then slides look just like the ones from me GS500. and i've had them out before !

Lew

[Studley Ramrod]

Hi Lew, errr no they don't go through the slides. In the 3rd photo you can see the end of the toob, rest of toob is buried inside the carb somehow.......entoobed fer all eternity.

Your carbs are different to these, just in case you were panickin'

[aircooled68]

What kind of condition where they in studders? just a clean and ready to fit ?

Ahh

Oh well then, not to worry, I ain't looked at my carbs yet, that our job once the toobs decide to turn up.

not heard anything yet so think ill mail them about that

Lew

[Studley Ramrod]

Yeah, kind of they were really filthy mind !



The internals were all noice and clean tho Not a trace of any brown bits in the bowls and no gummed up jets etc

I've just about got 'em ready fer putting bacon me engwin.

[dablik]

Errrr Ian you gonna have ya bike done for Trev's fettle day m8 or av ya told Lew ya goin pillion

[wicklamulla]

these carbs can be fitted to MKI's and the earlier MKII's (1996-1998) just incase anyone wondered, ya moight hafta change the airbox to carb rubbers too though. I remember a dude fitted some to a MKI a couple of years back.

[Studley Ramrod]

Probably Cliff Might leave some of the fettlin' fer the fettle day eh !

Obviously, if someone else were doing the fettlin' for me.......cough cough

Onee kiddin' mate ! I'm still on shedmule....just.

Wicky, if I'd known about these carbs and what's inside 'em, when I ad me mk1 wan, I'd a fitted 'em also.

I did a visual check on the toobs and they look perfectly round after 34,000 miles

Yeah, you'd need to swap out the airbox rubbydubbys if you were to fit 'em to any other 8fiddly. You could also modify the cooling system and take advantage of the carbs heating plumbing arrangement.

[wicklamulla]

do MKI's have carb heaters as standard ?

[Studley Ramrod]

Nope, no tps either.

[wicklamulla]

i gnu there was no TPS but assumed they had coolant diverted thru de carb bodies to warm dem up !! aint broke don't fix it.

[robelst]

I thought he Mk2a had TPS? The 2001 manual explains how to check and reset it.
I will soon find out, my Mk2a seems to have developed a nearly permanent carb-icing-like problem at low/mid revs (not electrical, leads/plus/coils are all new) so I either suspect the TPS is playing up, something is leaking or blocked, or a bird has built its nest in the air-box. MPG is still excellent, so no worn tubes. Compression is fine too, performance is still very impressive. It's done 71k miles now, apart from this and the clutch having run out of adjustment (not slipping though) it seems pretty healthy. I should probably move on to something fresher but it's become like an old pet: You know the end is inevitably near but throwing it out before it's really dead simply isn't an option

Rob it does but u need to read the whole topic

[Murphy]

Hi Every one, I have these carbatooters on my 2000 TDM, does any one have any information on how to check the float heights, as I cannot find any marks on the float bowls, anything on the internet is for the earlier TDM's thanks.

[dablik]

It's on here some place Murphy, between studley and dappers it got sussed, maybe piccies even, try a search.

[Studley Ramrod]

Is it ?  I don't remember stuff that far back so you might be right.
