Mikuni 26mm Yamaha TTR125 PreJetted Carburetor

Additional Information

Fitment Information

• I have a 01 with a pipe and machined flywheel would the 26 or 24 be ideal. I use the bike to ride with my kids and will eventually do a big bore but want to do 85 conversion first. Thanks, Mike

  I highly suggest the 24mm carb. Even with significant modifications to the engine, the 24 almost always outshines the 26mm

• Hello. I have a 2017 TTR-125 I just bought a BBR 150 big bore. It’s got an FMF pipe/header combo. Will the 26 or 24 be a better option? I am at sea level.

  If you don't have a high performance cam in your bike or larger valves, you'd be better served with the 24mm. In the world of carburetors, you're better off a bit small than too large.

• Will this work on a 4 stroke, 125cc Chinese pit bike? I have an Xpro 125 and the carb is horrible and I cannot use Mikuni jets...

  No, this is setup specifically for the TTR125. I imagine the pit bike engine is significantly different

• So i have a 02 ttr125 L running white brothers exhaust, bbr150 kit, performance cam, high flow air fir, air box mod as well. Ful bbr suspension and cradle. Looking at getting head ported as well soon. Better to run 24vm or 26 since i do slot of mixed riding?

  Its pretty hard to go wrong with the VM24, even with the mods you have as well as the future mods planned. With that said, it really comes down to preference. If you feel that throttle response, and low-mid range power is more important, than some additional top end performance potential, I recommend the 24. The 24mm to me makes for a more fun bike. If you just want to be faster than your friends, the 26 will make more power up top.

• Does this carb need any type of adapters or will it fit the stock intake boot and stock air boot as well?

  Adapters are not needed. This carb will mate up with the stock connections on both sides. If you arent sure you need the VM26, I highly recommend considering the VM24. The VM24 also mates up on both sides, and performs better for most setups.

• I have a 03' TTR-125L with a big bore kit and performance cam. I plan on putting on an exhaust and free flow filter kit. Should I go with the VM24 or VM26?

  If you were to fit the less restrictive exhaust and air filter, and combine it with your big bore kit and cam, you could use the larger VM26. That's because your bike will have the ability to take in and exhaust more fuel/air mix than a stock TT-R125. With the bigger carb, you'll gain a little more top end performance, but you'd have better off-the-line and mid-range performance with the VM24. Most people ride using bottom end and mid-range with occasional top end, while racers look for maximum performance at wide-open throttle settings. As long as you've modified your engine for performance, your choice of carb size really depends on your riding style.
