We get alot of guys emailing us about the proper direction to take with there jialing engines



heres a step buy step list from the guys who have been building these since the first one hit pm



#1 good air filter

uni pod or new tb two stage

#2 Crower g2 or tb 411 (only if your NOT going directly to a bvh set up )

this will give you a nice boost till your rings wear out if your just fun riding



#3 tb146cc kit (pretty high comp with stock head may require race gas )



#4 lifan big valve head with tb300 cam or (if you can swing it )sgr head

and a 26mm carb kit (dont waste money on a carb till you get to this level of flow )



most guys wll see enough performance and get good reliability with the lower comp tb pistons



some guys will want every thing possible and look into akuner pistons

just remember high compression means race gas and other possible lifespan decreasing conditions



some guys will want the most radical cams and head set ups like sgr and z40

but again valve springs may wear faster



we have had very good luck with the lifan heads and the tb 300 cam set ups like the t-5 engine we dyno ran that had 15.4 hp

good solid performance with good overall reliability

Too bad this got moved.(There is a differance between propaganda and general info) At least the link is on the front page of the china section.



On that 15.4hp dyno run, was the lifan head ported, or stock? I am looking in the ports of my lifan and can see lots of power waiting in the wings. But at a reliable 15+hp stock(the hp# I am after), I would do a clean up/knife edge rather than a pay for a full bench flow.

Now that the new GPX is coming out, dont know what to do.


just dont too excited unless your going to be ready to spend some money on the new style engine



we know exactly what were doing with the new gpx 150

we have a 165cc kits NOW for the new motors and some stuff i cant even talk about



the original gpx 124cc outfitted with the 146cc and b v h will continue to be a solid contender and a great value

Just paid for one Bob. I can't wait for it to arrive. I will be doing a 146 kit with 26vm mikuni and lifan bvh. I hope it shreds on my stock xtreme 8hp engine. I hope I get 11+ hp out of it.
