King Motor REV 4 Bolt 30.5cc 2 Stroke Gas Engine Fits HPI Baja 5B 5T CY LOSI FG

I have gotten a gallons worth of fuel through this motor already. Super powerful and it does put some wear on your tires. Doesn't vibrate nearly as much as my last motor and does look very well built you can tell in the aluminum casting. My old motor had a bunch of sharp edges and imperfections but this one was nearly perfect. The only reason I gave it 4 stars is because the pull starter isn't good at all. Came apart on me during tank 3 of breaking it in. Good thing I kept my other pull starter from my last engine. Do yourself a favor if you get this engine, just replace the pull starter right off the bat before you even put it in the vehicle.

Motor is absolutely amazing. Put this in my hpi 5b and it does wheelies when it gets traction. I have gone through 3 sets of rear tires since i put this in. Ive put about 15 tanks through it and its still going on the original spark pug.

great motor. The pull starter did break after a two pulls but they sent me a upgraded one asap. Very pleased with it so far. Only thing I've had to keep an eye on it the carb bolts don't have lock tight. And have loosened up during play time. Just make sure you lock tight them before you run it. Other then that love it.

Bought a GoPed Motor, it didn't even last 2 full months before it completed stopped working, asked for it to be replaced and they refused. Looked order up and found they don't even sell it any longer. They don't warranty their products, what does that say about it???? DONT BUY from them EVER!!!!! Pre warning to future customers.

I received a 3 bolt engine instead of a 4 bolt engine. Not very happy at this time.

These are wonderful motors . There are some things i would do before bashing the motor . step one run 4 tanks of 25/1 gasmix threw while given it a 2hour cool down after every tank to allow the motor to break in fully . this allows the motor to last a lot longer. step 2 replace the pull cord . step 3 make sure every bolt nut is tight take it apart make sure everything has lock tight this in sure your engines life .... do not over rev your motor . meaning don't have it floored for long periods at time . you wouldn't do it with your car or truck you drive every day.. even thou it is a 2 stroke high reving engine doesn't mean it can handle it for long periods at a time something will break. an kills the life of the motor .. allow the motor to cool after every tank of gas forr about 30min of play time
