TOMBERLIN YELLOW CROSSFIRE GY6 150CC GO-KART ENGINE,--GUARANTEED FIT

YOU HAVE PERFORMANCE OPTIONS WITH THIS ENGINE--SEE BELOW

This is the 150cc GY6 engine for Tomberlin Yellow Crossfire go-kart with no reverse--Guaranteed Fit!  If you have a reverse on your go-kart it was likely purchased from us.  Please let us know so that we can send you the long drive shaft on your engine.  Your engine comes with an American made Uni-Filter, which is a high performance filter that ensures clean air to your engine, and also get 4 sets of roller weights.  If you are buying a new engine there is a good chance that your old one failed from a poor air filter.

Also included:

  • Standoff for muffler.  No kick start to interfere with your exhaust!

  • Longer drive shaft to accommodate a reverse gear box but will work without a gear box also. 

  • New American made Uni-Filter for clean air to your engine.  See why a NEW Uni-Filter is MANDATORY for ALL new engines.  Don't get an engine without one. 

  • Four sets of roller weights for you to optimize top end speed and low end torque of your vehicle (9g, 10g, 12g and 14grams)




      OPTION 2: Performance Transmission plus Option 1:

      High Performance Transmission for Better Power Transfer to the Wheels:

      This option includes High Performance Transmission: 1500 PRM Spring and 10 gram rollers, performance variator and high stall clutch and thus more torque and more power due to more efficient power transfer.  See price options at the top of the page.

       

      OPTION 3 - 175cc Engine plus all items from Options 1 & 2:

      We can even convert your new 150cc engine into a 175 or 184cc racing engine.  Both of these engines come with the performance transmissions and the Uni-Filter. See price options at the top of the page.:
