Engine runs fine not really had any problems with performance so far and I’ve had it a year now. I ordered a billet side cover for it so I took stock one off and when I got to looking around inside I noticed rod is cast. So I came to website and looked up connecting rods to see what is offered and there I seen my rod for $16. And the specs says it’s a forged rod . Hopefully it’s just a mistake but from now on I’ll be building my own engines
Very surprised of power and torque this motor has, I worked on cars all my life but have downsized to go karts due to aches and pains, LOL. I put this 225 Performance Engine along with your juggernaut torque converter on and just got it running last night, surprised the heck out of me, it is Snappy. You do have to do some grinding on one of the fins of the mounting plate of the torque converter as it hits the oil fill opening, but all in all very satisfied!
Decided to get serious with my drag racing. This engine landed me at low 10's in the eighth mile. Slam dunk. 10.07 fastest pass, runs great to pull .01 rt. Solid build.
Easy instal and soooo much fun on my hurricane! Customer service was awesome to provide bolt sizes and thread type. Combined with a juggernaut and new tank. Transformed my bike and the experience! Now I’m doing wheelees up my hill… almost on purpose :)
Engine is great out the box, it'll out perform anything you can cobble together and is dead nuts reliable... 67mph on a yard Kart in the quarter mile. It'll run faster if gear for Max speed ...
It’s been good so far about 15 hours in after break in Ik the governor is off but is their a limiter?
225cc Tillotson Performance Engine
Awesome engine haven't tried it yet but runs in the stand like a champ sounds soooooooo gooooood
I love it. Coming from the 2 stroke bikes this thing is night and day. I was sold on the first throttle pull
This engine has totally changed what i think a mini bike engine could be... put it on a trail master ..after modifing my torque converter (drive and driven pulley) with a juggernaut and a green spring on the back ..its a easy 60mph beast....
