That's easy. The 141cc pulls just like the 114cc, but more of it. And the 190cc pulls just like the 114cc does, But there is a ton more of it. For an all around play trike I'd do the 141, Because of the Semi Auto with the beefed up clutch is AWESOME.
Perfect answers as always! What you described is both what I was hoping and guessing for on how these motors pull compared to the 114cc engine. Don't know why I love that motor so much but I do.
Going off topic but it's ok as it's my thread right?
Back story..... Last weekend a friend of mine came over to ride both my ATC 70s and see how each of them perform. He recently bought 2 ATC 70s that are stock and he wants to build up one for him and one for her. He wants a hot rodded one for hitting the dunes and hauling his 6'4" frame around w/o any problems and the other to be more mild where any adult could handle yet enough power to make you grin with each wheelie.

Sounds familiar right?
So he rides the 114cc, is ripping wheelies in minutes and can't wipe the goofy grin off his face. Then I put him on my warmed over 150cc Piranha and within 2 miutes he had a serious look on his face and was like "here, you can have it back". LOL I made him ride it a few more minutes as he had been talking about buying the Piranha 150cc e-start engine like you have. So after stalling it several times while starting out due the the low inertia of the trans mounted clutch. And also having it feel like a wild Bronco that is constantly trying to flip you on your back when you stab the throttle he was wanting to get back on the 114cc trike.

He did and appreciated the smooth powerband even more so than he did during the first ride on the 114cc trike.
So, now he is confused on what to buy/build for each of his trikes and wants my advice. He watched the GoPro video of me on my 150cc in the dunes and knows he wants that much power but not sold on the power delivery of these larger manual clutch motors after riding mine. He absolutely loved the feel of the 114cc but we both fear it would be rung out to death on the dunes with a rider his size and could use a few more hp. I suggested he get a V2 Works 141 Lifan and he would likely love it but he is concerned it won't be as powerful as my 150cc for the dunes.
I'm convinced a Works V2 head 141cc would have more hp than my 150cc with Z40 cam, thin head gasket and ported stock head but he does not completely believe me.
So after all of that back story........ John, how does the power of your 141cc compare to your 150e start motor? Which is more powerful in the dunes and how does the power delivery (drive ability) of each motor compare?
After talking with my friend I have been thinking about a 141cc myself but then I got the silly idea of using an Anima 190cc since they are very similar in price once you are done building up the Lifan to the level of yours.
Appreciate your help and input!
