TB 26mm Performance Carb Kit, Mikuni VM26 – KLX140

TBparts VM26 performance carb kit for the KLX140. This is one of the best, if not the best, carb kits you can run on the KLX140, with or without a big bore kit. The Mikuni VM26 has a proven track record for delivering high performance, reliable quality, and easy tuning.

With a +6mm increase over the stock carb, the VM26 boosts power across the entire RPM range while still working with the stock air box and filter. It’s a bolt-on upgrade that delivers real results.

We stock all replacement parts and jets for this kit. For comparison, a stock OEM carb alone is over $320—this kit offers better performance and value.

The kit includes:

• Genuine Mikuni VM26mm Performance Carb (Not a cheap Chinese copy carb)
• Intake Kit port matched to the VM26 and stock cylinder head
• Stock Main Jet size is a #190 – Extra jets sizes 155  165 175
• Stock pilot jet it #22.5
• Extended Throttle Cable for use with the stock bars and throttle or tall bars.

Tuning info – The stock #22.5 pilot jet and #190 main jet works well for most 170cc big bore kits
