Mikuni flatslide ID help

[DixiePlowboy]

I'm hoping that this carb is a 38mm, but I'm unsure.

The only numbers on it are:

upper flat, intake side- 38C
127


lower flat, intake side-T4
92


It's got a 260 main jet in it. The only comparison I can make with another carb is a roundslide Mikuni that I was told was a stock Tecate carb(but that isn't verified). The airbox side bell and the intake side are the same outside dimensions, but the inside diameter on airbox side bell is noticeably bigger on the flatslide.

If this is a 38, I'm hoping to make it useable for much less than the price of a new carb. If not, it's probably going to get a 39/41.5mm taperbore from FTZ.

I'm caliper poor at the moment. Like everything else I do I find myself going about things as the cavemen had to do it....lol

This is for your 200X hybrid correct? 260 main is HUGE!!

'85 Tecate.

Using Sudco's website and a tape measure, I narrowed it down to either a 36 or a 38. Then looking at the parts blow up, found that only the 38mm had a particular bolt as did mine. Guess I'll try to work with this carb.
