anyone w/ zongshen 125 motor or ahp stage 1

im looking to get a new motor..ive been looking 4 ever but cant seem to find enough info on whats good...i see the zongshen 125 motors on ebay alot they arent replica ones they are the real brand are those any good? and also what about the ahp stage 1 motor? what size are those, i hear those are good but dont know anything about them ..

i need to replace my sdg motor which is pretty much shot asap

zongshen makes deasent power, but you run into problems with the transmission. downshifting they will skip from 3 to 1 or 3 to neutral sometimes. Vinco is making a product to cure that problem on them though. Haven't heard anything about the ahp motors

I recently purchased a couple AHP stage 1 engines (100cc) from Mark at AHP and they've been really great so far. I don't have any riding experience with the bore kits and how they compare, but the AHP stage 1 hauls ass and it has 1down/3up trans. Install seemed as close to plug and play as it gets, I followed the instructions for installation and both engines fired right up. The only obstacle we encountered was the stock peg mounts hitting the engine. This was easily fixed by using longer bolts and washers as spacers to space the peg mounts away from the engine. As far as performance, the engine pulls strong throughout the entire power curve and sounds really good. I also added a Uni pod filter, a TB RevBox and and 15t front sprocket to complete the package. All in all its been a great engine and I've read about others having good experiences as well. Mark at AHP has great about answering questions and communication throughout the entire ordering process.

Here's a pic of my AHP Stage 1 (before the uni filter, TB rev box, and sprocket) ---->

sorry to jack the thread but how is vinco fixing the problem of the false neutral?

I love mine! I've had it a few months now and I still love it just as much as the day I got it. Starts every time first kick.

what do you have?

anyways i got the zongshen 125 and that thing halls! i did have that shifting problem but it went away after i broke it in all the way and put in 20-50w oil

sorry to jack the thread but how is vinco fixing the problem of the false neutral?

The problem is with the star on the shift drum that catches and maintains the gears when shifted. They have redesigned the shifter star and are making it now.

The stage 1 motor is really nice.Its got alot of power and the tranny is like buter.Also Mark will back his stuff 100%.

i can buy a sikk125 motor for 399 from sikk..does anyone know is sikk uses the zongshen motors? or are they just copys of them, i just need a motor replacment that will outlast my sdg motor

IM about 99% sure that they are copy of the zongshen motors.

so if i got a REAL zongshen 125 motor would it be pretty good??

i can get a REAL zongshen 125cc for like 415$ i dont wanna buy something thats completely junk but i also dont wanna spend a ton of money cuz im not planning on riding my pitbike a whole lot since its been like 110+ outside and college is just around the corner agian so i'll be busy...im just trying to get the best thing for that price range

The Zongshen motors aren't that bad. The engines that we have come accross have a 27mm int. valve and a 23 or 24mm exh. valve (I can't remember which) 54mm stroke and 54mm bore, the transmissions are descent, we made the parts to fix the shifting problem. The clutch is a primary unit, but will also work with the kitaco and takegawa secondary clutch upgrades. We also have cams, carbs, carb kits, and exh. that really wake them up.

Hey Jacep,

Looking to start mods on my Xtreme / Zongshen (125), would like more info on motor mods. Are you at Vinco ? I couldent find anything on the site. Let me know. Thanks

give us a call and ask for Jace, we are still trying to update everything we're just way behind sorry man.

would it be a dumb decision to sell my stock crf50 motor and just drop in a zongshen 125cc, im not really probally going to be racing the bike, but still want to beat on my buddys around here

what do rev boxes do, and how do better ones make the bike faster?

anyone know anything about Lifan motors?

is there any place to just buy an already shaved shift star or just a pics of a good shaved one would work

thanx

ahp motors are really nice

if i didn't already have a bore kit i would def run it
