will the 200 cc one work on a 200x

[hotrod 110]

The lifan 120 with the clutch mounted on the main shaft uses a longer cylinder than the stock ATC70 motor. And yes you can mod the motor . Guys on planetminis have run then out to 180+cc's but you have to split the cases , use a stroker crank bore the cases for the longer crank and once they get out that big reliability becomes an issue. A simple swap of a cam and a higher compression piston, a bigger carb 24-26mm and an aftermarket pipe really wakes these motors up.

How are the Loncin engines copmared the Lifans

[hotrod 110]

Loncin,Lifan,Zongshen,GPX are all about the same motor. Not that familiar with the Loncin , I think they use that in the Sikk50 bikes, but Lifan and Zongshen both have big valve heads (depending on which model you get ) 27mm/23mm valves in their big valve heads found on the 120's with the clutch mounted on the main shaft(starts in any gear). GPX has smaller valves but they have an all up shift pattern ( if you get a newer style) . The Lifan has a 1 down 3 up pattern and there have been some issues with false neutrals ( shift from 3rd to 2nd and the bike goes to neutral) Zongshen has a good trans and if you get the 125cc with the clutch mounted on the crank it too has the big valve head plus you can use your Honda semi-auto clucth ( swap out the manual for the Honda semi-auto and use the Honda cover). Lifan / Zongshen use the same style stator plate as the Honda . If I was going to do a swap I'd get a Zongshen 125 use the stator , flywheel and side case cove from a TRX70 , clutch for my Honda and bolt in and go. The 125 makes tons of torque get a 22mm carb , great throttle response but you loose some top end.

his is the one i ended up purchasing. I was really trying to stay in the 90 range so it wouldnt be too much for the kiddos, but i think i will put a little taller gear in it so it dont flip them on there but so easy. What gear front sprocket should i run. What do yall think of this motor. It looks as if it comes with everything.

Good deal on that motor, here is a couple of pics of a Lifan install that Whtcamaro and I just finished up on his, got it running last week, now just some small stuff to clean up. 110 manual 4spd. using a YTZ7s Battery from a TRX450X I think, and a SeeDoo Battery strap. This battery is real small with 130CCAs. With it mounted like this everything is hidden and easy to access. ( Battery mount idea from Treshombre at Glamis.com) BBR CRF50 Big bore pipe with a custom rear mount. With this pipe the rear fenders will need cut at the back like the one used on a A+ suspension frame. I have a White Brothers pipe on my A+ frame it it fits nice without the mount. Good luck and we will try and help as much as possible.

That is a good idea for the battery mounting but i dont have a welder. But i have some ideas i am going to play with. It sucks that i have done painted it though. oh well. 1 more coatwant hurt.

I have converted a lifan 125 to pull start and posted pictures of glamis dunes. I just need to do a little more work on my cover and hopefully I can get the cover chromed to match the rest of the engine covers. Let me know if you have any questions. It is easiest to use the lifan cover as you will need to mod it very little. I have learned that you can use the atc70 cover, but it will need more work than the trx70 cover, and the trx cover has the plug already in it to use the timing mark. On the atc70 cover, you will have to remove a portion on the inside of the cover to get it to work.

Hate to bring up an old thread, but saw your post and thought it was worth asking about since I haven't seen anyone else mention that it was easier to use the lifan cover to convert to pull start. Please elaborate. I am about to do my swap and have thought about using the lifan cover to cover to pull start vs messing up my 70 cover.
