Thanks to Mike Tiberio for providing this information. In his own wordsâ€¦
Recently there was a Mikuni carb setup for a SP 1000 on ebay. I bid, but didn’t win. I contacted the seller (Steve Braun), and asked if he would share the jetting information he learned in setting them up.
These carbs are available from pro-flo.com for $90 new, but without a baseline, you could easily spend that much buying tuning parts to get this close. He sent me the following info (with selected edits by me).
Here are the particulars for the Mikuni setup for the SP 1000.
VM32 round slides
159P0 needle barrels (I think he means atomizers or needle jets here)
6DH3 needles clipped at the middle position
170 main jets
2.0 air jets
The SP1000 was completely stock.
Both intake manifolds are # 14115002 (Right Side). The left carb won’t fit with stock left manifold, the carb hits the motor.
The intake manifolds should be blended on the inside to match the carb opening.
The air cleaners are K&N RU-1730.
The installation fits very neatly if the battery is not oversized. I used a sealed Interstate unit: Y60-N24AL-B
The carburetors came from Stan Smith at Rocky Point Cycle 937-376-9792
