33mm carbs

Let me know if you ever get them to idle consistently if you ever get the right carbs. I traded mine for a set of 29s. They do run good WFO. No way the carbs pictured are 33 smoothbores, Ive had then before

Again, by his logic, these 26 mm carbs must be 34's.
Or, 26.5's?

i can do nothing now until i receive them and take some measurements. i will post up the results then after a bit more feedback from you guys i will decide whether to go ahead and fit them or demand a refund

but he swears the id is 31mm?????? and the od is 33mm. i will have to take my carbs off tomorrow to take a few comparison measurements unless any one has got the spec on the id and od measurements of a vm26 handy :)

just a point here, he says id 31mm od 33mm if thats correct that means the spigot is 1mm wall !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! it would be about as strong as tissue paper
the spigot should be about 3.5mm thick

i think he means each engine no, matches each frame which sounds ok to me

If he does then it'll be a first - the engine numbers and frames numbers don't match on any of our bikes.

He's dropped that price on his 1100 swinging arm now I see. Getting there.
 
just been on the phone to a guy who used to race GS1000's and he says boring out the carbs was common practice in his day.
i cannot draw any conclusions until i get them, tomorrow hopefully.
i will measure them and inspect them meticulously and then decide if i have bought a bank of scrap ali. after all he did say on the phone he measured them with a tape measure!!!???? i got a digital vernier.
maybe ill get a few quid back just for the engraved slide tops haha
 
right, so the carbs turned up today. measured with a digital vernier, the inlets average at 28.2 I/D. 33.8 O/D and the inlet walls at 2.9mm.
so at a "wild" guess i would say these are standard 28mm VM's......
they have a cable operated choke (which dosent work) and the throttle is jammed half open. pretty good seeing as they came off a "running" bike.
i am not overly bothered because they will be stripped completely and rebuilt.
question is, do i give the guy a gobfull and demand a partial refund for selling me something "not as described" or do i just give in and be thankfull that the carbs are actually original and just need work, which i intended to do any way?
 
just took the tops and bottoms off. no gaskets on the top covers, the bottom float bowl gaskets were in a bad way, all the jets blocked up AND i have seen it all now........
he or someone had sprayed the INSIDES of the float bowls black?????????? WTF?

IMHO, stock carbs in need of a complete rebuild are only worth $50 plus shipping.
I would not pay more for them.

Eric
 
got a ?30 refund off him after i threatened to send him them back at his cost, gonna be a nice little project now but at least i will have a decent set of 28's at the end of it
 
they are defo 28's. no sign of any machining in there and they are all pretty consistent.stripped one float bowl and the paint mainly fell off. no primer etc.just got to unclog all the holes.
why the hell would you spray the inside of your float bowls?

Because you can...

Buy a tin of matt black and the world is your oyster in the world of motorbike custom paint jobs...:( You've seen all those real beauties that come up for sale all the time :eek:

Make sure that that diddy hole at the bottom of the float bowl for the choke pick up is clean - that'll clog easy with that sh!t (sorry, custom paint) in there. Did the choke ever work again after they were painted? Well, they did come off a running bike.
 
no idea lol. the whole lot is being stripped as i type. can i replace the cable choke with a lever type choke from the 26's?
