Mikuni VM/TM Needles & Jets Listings of all the Mikuni VM needles: Sudco NicheCycle. (The Mikuni needle data on my spreadsheet is even better than what they list because it has corrections for obvious errors they made in copying.)  Here's what Mikuni VM's typically are equipped with.

The normal #5 series of standard Mikuni needles are suitable for the TM34, and the #6 series is good for the TM36 to TM38 non-pumper carbs. Listings of all the standard Mikuni needles: Jets R Us (but theirs aren't all genuine Mikuni needles). NicheCycle and Sudco also have needles. SUDCO: VM carb parts, Mikuni needles, Mikuni jets, VM slides, TM carb parts. (The #5 and #6 data on my spreadsheet is even better because it has corrections for obvious errors in copying.) Each MIKUNI NEEDLE is identified by the letters and numbers stamped on them. Example: 6FH7 6 is the length, which in this case is more than 60mm but less than 70mm F is the top taper, A-E having less taper H is the bottom taper (sometimes the NEEDLE has only one letter, in that case it refers to a single taper) 7 is a mfg code not normally used in tuning.
