TB KLX140 Big Bore Kit, VM26 Carb Kit, & Performance Camshaft – All KLX140s

TBparts 170cc Bore Kit, VM26 Performance Carb Kit, and Performance Camshaft package deal! All the engine parts needed to optimize your KLX140s output and make it a race ready machine! These parts all work great together for an unmatched performance increase. Starting with the complete big bore kit you get a lightweight high compression piston that is 5mm over stock making close to 50% more power. Add the 6mm larger VM26 carburetor (that utilizes the stock air box) and the bike will not only start up and idle better but it also feeds the engine more air and fuel to make more power through the powerband. Top it off with a cam that starts bringing in more power in the midrange and allows you to turn close to a few thousand more RPM making more power and you are ready to race! This is one of the best, if not the best kit you can run on your KLX140 to reliably wake it up without breaking the bank! We stock replacements for everything in this kit and jets for the carb. Not to mention we are continuing to grow our performance and replacement KLX140 parts lineup!

Kit features:

  • Huge power gains at the best price!
  • Aluminum cylinder with steel sleeve (63mm)
  • High compression 63mm piston with rings, pin, & clips (Safe on 91+ Octane Pump Fuel) (Note: The arrow on the piston marks the intake exhaust flow/valve relief)
  • Top end gasket kit
  • Genuine Mikuni VM26mm Performance Carb (Not a cheap Chinese copy carb)
  • Intake Kit port matched to the VM26 and stock cylinder head
  • Main Jet kit (Stock Main Jet size is a #190 – Extra jets sizes 140, 145, 150, 155 (x 2), 160, 165 (x 2), 170, 175 (x 2), 180, & 185.)
  • Extended Throttle Cable for use with the stock bars and throttle or tall bars.
  • Brand new camshaft and bearings

Note: 2025+ KLX140s require case boring to fit. Our cylinder skirt is 65.95mm 2025 cases are only 65.4mm wide.

This kit does not require boring of the case – simply bolt on and go! There are no installation instructions, but if you can replace your piston, you can install this kit. If you don’t have any experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Kawasaki dealer. The parts are installed in the same manner as the OEM parts.

Installation note – KLX140 camshaft bolts are reverse threaded, turn them right/clockwise to loosen/remove. A good jet starting point is the factory #22.5 Pilot and #185 main with the stock pipe.

Kit includes parts TBW1543, TBW1544, TBW1545, TBW1539, TBW1546, TBW0399, TBW1353, TBW1515

Overall good frother
Color: Black
Bought the Maestri and the Zulay frother to test which one is better since both had good reviews. Returned the Zulay (see Zulay review) and kept the Maestri. Been using it for a few days now and works well. Mixes chai and hot chocolate well. It has one speed that is a good speed to mix, but not so fast that it causes the drink to spill over the top as long as the cup is filled to about 80% full. Because I tend to use the tall 20 oz Contigo autoseal cups, it could benefit from offering longer attachments to reach the bottom of the cup (note: that I did not find any company that offers longer attachment arms).

LOVE this frother and the creamy results!
Color: Black
I LOVE this gadget! And I'm not a gadget person. Since I got it a few days ago, I've switched from using my Nespresso coffee maker, which uses pods and which I really like, to using Starbucks instant coffee packets (cheaper and more environmentally friendly than pods). I put a packet of the coffee and two packets of Equal in a cup, add half and half, then use this frother to mix them. Within a few seconds -- no more than 5, if that -- I have a thick mound of creamy froth. Then I had the water to finish making the coffee. Fantastic. This thing is so easy and fun to use. This is not the cheapest frother available. I wanted a rechargeable unit that has sufficient power to make nice, creamy froth. Also, I didn't want to spend $10 and have the thing break and have to replace it. Reviews suggest the cheaper ones are fine if you don't regularly use a frother. I never used one before and didn't really think I would use it very often. But I like it so much, I've been using it twice a day. Also, I first saw one in use while traveling in India. Another guest at my small hotel had one, which she used to make a latte with rather than drink the rather tepid offering at the more tea-oriented hotel. That's when I decided to get one. I'll be taking it on future trips. Some come with travel containers; this one didn't. The only learning curve was making sure the cup or pitcher for the cream is deap enough not to splash out the cream. I think I'm actually using a little less cream than I used to because the volume increases so much. I use cold cream, not heated (I used to heat it in the microwave when I was using the NesPresso.) I find I like the initial contrast with the cold cream at the top, then I stir it down into the coffee. The Starbucks coffee is excellent. I've used it for iced lattes in the past, so I knew it was good. I can hardly wait for a heat wave to make them with this frother. I did try to beater attachment in eggs when I was making an omelet. Not worth the trouble -- first, the bowl I was using to beat the eggs was too shallow and egg got all over. Second, a fork works just as well. If I were whipping cream, I would definitely use it.

Works great and so much fun!
Color: Black
How did I live without this for so long? I love this little gadget! It gets used multiple times a day. It's not only great for frothing milk but it will whip eggs for a recipe and stir other ingredients as well. People who have complained that the stirring attachment was missing a piece did not read the description. The picture clearly shows there is no "boot" on that attachment, you don't want that one to spin like the frother. The Frother holds a charge for quite a while as well. I use mine multiple times a day and it is still holding a charge after weeks of daily use. Great item!

Disappointed
Color: White, Color: White
Powerful, but the description differs from the actual specifications, and the speed cannot be adjusted.
