Motorcycle Throttle Body size reference?

[greggearhead]

I Was wondering if there was a site (or a really knowledgeable person) that has all/most of the throttle body sizes available from motorcycles?

I am considering using them on my 2.0 16V project if I can find the right size, but it is difficult to find sizing for them.

Thanks for your help.

I just got 2 sets of 4 CBR929 TB's from West Coast Salvage (UK) through ebay.

40mm capable of 150bhp on the bike, so 2 sets should be fine for a small v8

Have a look at http://tinyurl.com/59kcl for some info, and drop them a mail for specific info ?

GSXR1000 2002 are 42 mm and 230 cc/min injectors.
GSX1300R was 46 mm I thought , but injectors don't know

How about a "sticky" thread with known specs on motorcycle TB like this:
(Any other info that should be in the list? pictures?)

Just keep posting, this thread or the sticky and I´ll put it in the list.
Hopefully we get more info as time goes.
Maybe I should change the name of the thread to include cars also?

[DominicMason]

I have been looking at the same set up for my car. I have been looking at the earlier style GSXR throttlebodies which do not have that extra butterfly in them, but they are harder to come by. I may go ahead and get the newest style since they are going so cheep. Even though I have a 1.9L I suspect 42mm should be large enough for the street. The jubiride kit is available in either 43 or 45mm......I am not sure what to do about velocity stacks though...Any thoughts??? For filters I plan on looking for some cone shaped, foam motorcycle deals that clamp on over the velocity stacks

[RosaleenRosy]

i have some experience of MC throttle bodies on cars, as i know two or three people who are using them on various 2.0ltr engines.

The GSXR 42mm bodies are MORE than big enough for a 1.8 ... in fact i know when guy who is running a 2 ltr Zetec on Kawa 600 36mm... and producing over 190 bhp ....

00-03 gsxr-600/750 have the same throttle bodies, same injectors.

[phulc]

Is there a throttlebody known with
center-center close to 112mm?
Ideally from a twin?

Best, Phulc

[James]

Is anyone aware of a more modern reference for throttle bodies?

Most of these are older now and therefore rare and/or expensive.
