jincheng panda 138cc
« on: September 30, 2007, 03:53:59 PM »
put a lifan 138cc in my 2000 panda "z50 copy".
i drive it to work and use it to run errands in town.
it goes at least 50mph and gets 100+ mpg. lots of fun and street legal.

Awsome man!  Where do you live?  Any issues with making it legal on paper of is the Panda street legal to begin with?  Was it an easy install?

I would love to see a few pics.

the panda is pretty much like the lifan pitbull. exactly really. wiring is eazy. there are three wires that mach and three didnt. i just looked on the wiring diagram and took the flywheel cover and looked where the mystery wires were going. done. the lights on the bike work tons better too. the bike is registered as a motorized bicycle on the mso. i should be getting the title soon. if some one wants a set up like ive got a lifan dealer would give a good deal to someone buying a 50cc pitbull mx pipe and an engine. probably $1200. keep the orignal 50cc engine or sell on ebay or craigs list for a couple hundred would drop the price to $1000 bucks. quite a deal for a street legal screamer. some people in japan spend over 10 grand on their z50s. i think now a 110 would be a better street choice for an engine. probably last longer. and the stock exhaust with minor modifications would work fine. a good paint job does wonders for the looks and getting rid of the crapy way cheap signal lights. i painted mine a metalic green like my ZRX1200. id like to eventually buy honda chromed steel fenders too.

oil cooled 138cc to air cooled-how to
« Reply #4 on: November 13, 2007, 06:18:19 PM »
well the panda is doing well and is a fine and very fun commuter. the last time i checked the mileage it was 125mpg. the orignal 50cc engine was getting 157mpg. that is with trail driving and my commute to work which is a long steep climb out of town. the 138 "oil cooled engine" is really ment to be oil cooled in case anybody is wondering. if there isnt an oil cooler or connecting lines mounted to the engine oil feed holes the engines head will starve of oil and melt your head. there is a way around it. i figured since id be driving on the street and usually have good cooling (and no big globs of mud packed in the engine fins) the cooling should be fine without an oil cooler. this is how you do it.
1 drain your oil
2 take off your kick start
3 take out the right side clutch cover bolts
4 using a rubber mallet tap the covers edges to loosen the cover. wiggle it around and pull it off. be carefull not to tear the gasket (there also is a spacer washer on the kick start shaft so be sure to put it back on the shaft when you reassemble it)
5 get a  handdrill and put in a 1/8 drill bit.
6 drill a hole bettween the (exit) oil cooler plug cavity (it is the pressure side of the oil cooler feed that is a part of the right engine case) and the lower right head/cylinder bolt cavity (that headbolt helps secure the cylinder and head down and is also hollow supplying the cam and rockers with oil) in doing this you are bypassing the pressue side of the oil cavity directly into the oil feed head/cylinder bolt.
7 take out the oil cooler feed bolt. spray a solvent of some kind up and down the hole you just drilled to clean out the aluminum shavings you just made. do a good job. blow it out with an airhose if you have one. put the bolt back in.
7 put it back together.

Wow, I never thought that would be possible!  Let us know how it holds up.  Are you a mechanical engineer or just self taught???

Hey everyone. Been a while.
I still have my Lifan. Still works great!
Done some changes. Resprocketed it. It goes an honest 60mph. Also bought a 70cc pitbull from hooperimports. Great little bike. Fun
