3 reviewsGENERAL DETAILS The Stock 250 & 300 head (especially 2014 and newer) is a VERY inefficient design and leaves A LOT of Performance on the table. We have developed a TRUE Performance Enhancer with this Custom Billet Head designed specifically for mountains and single/dual track riding. This head will widen the engine's effective power-band considerably and allow for a much more linear power delivery. This head is unequaled in its performance. Cooling is also increased. A cooler running engine will last longer and produce more power. Testing has shown, in many cases, this head allows for the hill to be pulled in the next higher gear . What you would normally pull in 2nd gear you can now pull in 3rd gear. Porting Packages are also available. This will wake up the engine even more! ANOTHER HUGE bonus with the addition of the head is improved fuel economy! Most find they can run an extra 10-20 miles further on the same amount of fuel!! Now who doesn't need that??? http://2strokeheads.com
0 commentsVery light and nimble, great ergos, inspires confidence and makes you want to ride every day. The versatility of the bike is almost unbelievable considering it's only a 150. It has great low end grunt, a midrange that is all about maintaining traction, and a top end that will shock your buddies on bigger bikes. It can be ridden off the pipe with great effectiveness (especially helpful on those slippery days) or it can be ridden like a rocket on the pipe. It resists stalling as well as any bike I've ever owned...and I've owned a LOT! I get 3.5 hours of moderately hard riding per tank of fuel, so the range is among the best in the business. Now the bad news. As delivered the bike does have a couple of serious flaws, but they are easily fixed. The stock reed cage is junk. Replace it immediately with a V-force or Boyesen and you'll never have another worry. The progressive stock power valve spring is not well liked, and most guys replace it with the alternate straight-rate yellow spring. Some even prefer the red spring (from the 250/300's). Once you address the above items (and I recommend doing both before moving on to the next issue) you will still find that the jetting is horribly rich. This MUST be corrected early or you will be buying lots of spark plugs. Don't worry, the Mikuni is a great carb, it just needs to be jetted correctly. Once done you will be rewarded with phenomenal performance.
