What size are my CR Smoothbores?

[liljegren]

I need some parts for my Keihin smoothbore carbs. I don't know what size they are- where do I measure???? I guess its I.D, on the engine side???? Anyone? Other than Sudco, who else can sell me a seal kit, o rings etc ??? Cheers, Matt.

Keihins are measured generally in a location only keihin knows, go off the id deal with Sudco as they are the international distributor.
their catalogue is awesome, likely has the id codes in it anyway as well.......

Size ID - two methods. On the engine side of the crosshaft housing, there may still be a black printed number,eg,33 1 This is 33mm bore, carb #1.
Alternatively, remove the screw in inlet stub on the engine side and measure the carb bore. Odd mm only, 31,33,35 etc..

Anyone but Sudco ? Ha. you'll be lucky.

For O rings try Seal Imports Ltd - I'm pretty sure they're a national company. Supply samples.

In the last 6 years I've managed to source two loose sets within NZ. One more with a bike. They're not common....

Sudco or ebay, occasionally seen for sale on the US sites like the GSresources or the Honda sites.
I generally recommend buying new from Sudco as new is just nicer to work with.

They for the Macca, Spyda ?

to swap for an original exhaust system for the Macca, as a swap i don't want to buy something and end up with him not wanting it so want damn good ones, which i'm happy to pay for.
