This http://www.auctionflex.com/showlot.ap?co=28464&weiid=5950355 bike ? Powered by a vertical Honda clone. What's the family# (16?FMJ) stamped on engine? Most 150 ohc ARE 145cc (61 x 49.5)
IF it burns some oil , the "kit" will be the solution.

These bikes were manufactured by Zongshen in the mid-2000s.

Well I did a lot of research on zongshen and it did lead me In the right direction but the bike I have is just like the one that humanbeing posted in the first link but its blue it doesn't have zongshen stamped anywhere on it..but I found the zongshen zs 150gy-10 or something like that they call the "fly" models looks like a newer version of my bike..I can't figure out how to post pics but does anyone e know the model of the bike in first link?

it looks almost identical to my Panterra before I modified it

...does anyone know the model of the bike in first link?

That won't be of much help to you, since that bike was imported with several different names. I have the same bike with a 223cc engine, and it was branded as Roketa. The Shineray is also identical.

What really matters is that you can find any of the parts you need on eBay or Taobao, but not necessarily by searching for a model name.

Ok there should be a pic of my bike this time..ok so could do different motor swaps to this bike like a 200 Sierra or the 223cc you were talking about?

Nice looking bike. A swap might be a real squeeze. I keep thinking some day I might find an older enduro, that is license able, with room to stuff one of these new motors in that have electric start unlike what the older ones came with. When you are drawing SS and 72 yo you don't want to be spending a ton of money. john

Cool bike. :tup:

Yes, you could easily swap in another motor of the same design. A 200 or 223 are the same dimensions outside; only the bore and stroke are different. It would require rejetting the crab, but that's easy.

A Sierra motor is not a bolt-in deal, because it's a Yamaha clone. Your engine is a Honda clone. The only Honda clone motor that you can't swap in easily is the counter-balanced version.

Most chonda 200/ 229 are OHV ("CG" family http://world.honda.com/history/challenge/1975cg125) which don't response well in high rev.

Cheers!

All I've done to the bike is put those bags on it..I been putting some miles I it runs and drives great but everytime I park it I go through and check every bolt the vibrations is pretty bad..lost my bottom bolt in front brake caliper yesterday then I had a short in ignition from a screw backing out the bottom fixed it then my headlight went out just vibration problems..also is there a way to mid the air box?

looks like they improved the mounting for the muffler. I had to re-weld mine 3 or 4 times, it kept cracking where the bracket was welded to the muffler.

I'm not sure what you're asking.

Buy some blue Loctite #242, and apply a drop to the threads of all fasteners. Totally worth it.

KPX did end up with a 200cc version of the bike--all of these were sold on Ebay for around $1k including shipping if I remember correctly. I ended up buying a very similar bike made by Shineray by a company called Jetmoto. These bikes from this era were the reason I started a Yahoo! group called Jetmotogroup or something like that, and another guy started Lifan GY-5 group or something like that, and Frostbite began this site pretty much off of both groups, but probably more leaning to the GY-5 group. I forget the members handle who started GY-5 but he was a long-time member. His real name is Mike, and he lives in Michigan--someone might remember him?

Anyway--enough trip down memory lane, LOL
