140cc Piranha Engine with 22mm Mikuni carb and electronics

Put this on my homemade bike replacing an 85cc honda, it needed more power...now it has more than enough. I'd put it around 3 times the power, I'd say 16 to 18 horse power.

This pit bike engine ended up costing $700 total. Since it was advertised to include a Minuki carb ($100 value), I justified the total expense. (If the motor blew, I’d at least have a good carb to use elsewhere). However, no Minuki carb as advertised, but rather a low end nibbi without extra jets came. It wasn’t even a black nibbi. Not as advertised. Slap! Slap!

the original Chinese engine was completely clapped out on the old Chinarider. This is a solid replacement. Currently we are getting about 55mph out of it and it manages in climbing offroad.Only negative is 400 bucks is a little too expensive for what it is.

The media could not be loaded.  So far I couldn't be happier with my purchase. This little engine is a monster! Tons of torque and top end! Want the fastest pit bike in the neighborhood? Get this thing!

had for less than 3 months and it threw a gear and I had to order whole gearset from China and I got it back together but not sure yet if it is working againBottom line is it's not 4 months old and needed transmission redone So No I Definitely Don't RecommendI wish I would have just bought a cheap one and I could have just trashed it and got another, with taxes this thing was 700 I could have bought 2 for the money

This engine is a monster!!!

Came with the box filled with oil and a broken case
