these Mikuni's now precisely returned back to stock configuration using both (stock supplied) 140 mains and 5C22 needles with other tricks as well. I'll proclaim these will run near perfect. Ready to go home to owner.

What size are they? They look quite different from my VM34s.

nice try, but these BDST38 Mikuni are the originally suppied CV carbs on 900,750 and 600cc (both SS and Monster models) up till '98 or '99 when they went to FI. Both jetting and internal differences existed between various models.

just arrived....a set of 250's allegedly leaking from RH carb side. I'll do a wet test first....prior to proceeding. Being used on a kart application.

supposedly "rebuilt"....I'll take exception to that. Immediate wet test cancelled/cleaning to take precedence.

Note EPA caps never removed to enable both cleaning of the involved pilot port(s) and oring replacement

These carbs were never split, on all 4 vent and fuel delivery rails the orings were both extremely hardened and dirty.

Nice float valve seats, too. I'm not surprised carbs were internally "leaking".

Hang in there for pics after my cleaning is done!

nearing completion, currently wet testing, both carbs perfectly stable, ZERO leakage, internally or externally. Wrapping it up tomorrow.

I'll surmise the leakage was due to dirty float seats, coupled with possibly incorrect float valves, more on that later after a comparison and precise measurement. More tomorrow. I'm played out today.

On left the original float needle (from a Far East carb kit used previously) and my currently installed needle on right

Note the Far East version leaked from RH carb
Mine are holding reliably in both carbs

May/may not be related in view of the poor condition of the seats as found.

Anyways, differences are obvious.
