The differences in perfomance numbers are due to variations in engine internals and manufacturing tolerances.Ĭheck out this video for a good rundown on how each stage compares to the others.
The different stages of modification apply to most Honda clone engines and they are basically the same on the Honda GX390 (big block) clones like the Predator 420 or Duromax 440. Since the top speed of your kart, mini bike, or whatever, is directly related to the top speed of your engine, getting more RPMs will get you faster. These modification stages are cumulative and serve mainly to get more torque, HP and a higher max RPM. The main differences between engines of this type are in the bore and stroke and the timing angles of the flywheel. They are overhead valve single-cylinder 4-stroke engines with displacements around 200cc and manufactured by a few factories in China. These engines are not all identical so the interchangeability of parts will be up to your own research, but generally these motors are VERY similar in design and function. I'm not affiliated with any of the youtubers linked below, I just found their work helpful. I'll include links to youtube build videos. This is just my own experience and research, if you ruin your engine injure yourself with this info, I am not responsible. When I first got into this a couple of years ago I didn't see this info listed in one place and I though you guys might find it useful. I have ordered more parts also.Here is a guide to what is generally considered the different stages of modification for the Predator 212 and other Honda GX190-style clones. The engine I purchased exceeded my expectations and arrived quickly. Posted by steve espinosa on 17th Mar 2021 Will this engine work on the Massimo MB200 Mini Bike? Man if I strapped this to an old Coleman mini I could do like 100 mph and 1/8 mile time of 8 seconds or less!
How fast do you think my coleman would be going after I buy this engine. I have a coleman ct200u and I want this engine. Thanks 5 I have a coleman ct200u and I want this engine.

Posted by Jonathan Daniel on 29th Apr 2021 I realize that not everyone has the space and tools that I do but that' s a little crazy.ĭon' t speak to me about labor for a few bolts and 15 minutes of your time either. I don' t get how some springs, a carb, and exhaust flange and a bent pipe should cost almost $300 extra. 5 212cc Predator Performance Stage 1 Racing.Ģ12cc Predator Performance Stage 1 Racing Engine.The powerful gas engine features a durable cast iron cylinder making it the perfect replacement engine for a go-kart, log-splitter and dozens of other machines. The horizontal shaft is mounted in the crankcase with dual ball-bearings, making this gas engine an ideal replacement for most standard engine configurations. This Predator 212cc gas engine has gas-saving overhead valves for cooler, cleaner performance and longer life. Connecting rod, flywheel, and valve train are all sufficiently durable with this engine package. We do not recommend any upgrades to this engine unless you plan to use a billet flywheel and a billet rod. Maximum rpm on these engines is about 5200 to 5400 rpm. We recommend a high quality oil designed for splash systemsto provide better protection. Always keep at least 16 ounces and no more than 20 ounces of oil in the engine while in use. This engine is blue printed and race ready, it is guaranteed to run but as with all racing parts there is no warranty. This engine is not for young or inexperienced drivers.
