Help identifing dual 44's

[lonloud]

Recently aquired these carbs from a barter deal.. I know they are 44's but are they Oem's, modified, balckjacks? Should i install in my 04 superjet with factory pipe, msd enhancer, prop, 160 psi comp..... is it worth the money to buy the intake to change from my stock 38's? Any info would be great! I did search but had no luck..

They look like really clean OEM to me.

There's a flat spot below the fuel pump is where Mikuni stamps #'s, can you read them?

Regular Mikuni 44's, not oem versions.

oem 44mm carb

regular 44mm carb

so regular mikuni (NON-oem) have 4 holes?

Those look like oem 44's to me that came on 6m6 or 61x as single carb setups.

The linkage between them isn't oem. Be very careful...if those aren't identical code carbs (for example one is from a 650 and one is from a 701) they will be about impossible to tune.

why would it be hard to tune one from a 650 and one from a 61x ??

 

[rossthaboss11]

they are two different carbs but look exactly the same. the 4 hole carb came off the 650's and cant supply the right fuel demand for the 701. the 3 hole carb is the real 701 carb. alot of people dont know this. atleast make sure each carb is the same. they are mikuni sbn 44's

 

[brentR]

but you could use two carbs that have 4 holes and same thread screws right?

are singles off 701/650 considered OEM or no?

I would make sure they are identical carbs.

Don't go by holes, go by model number stamped on the carb.

ok cool.

and a carb from a single motor (blaster etc) is considered OEM or not?

 

[Matt_E]

If it came originally with that motor, then it's considered OEM.
