Ok here is an update. we got the pipe mocked up. It's having the final weld done tonight. Most of the wiring is done. Just got to do the lights, and there are a few body work tweeks to be made so that it will work with the 200. Here are a fews pics so you can see the progress thus far.

WOW thats gonna be a fucking beast, any chance that you get that thing registered?

[Blackbird2xx]

Oh yeah it's a ysr 50 yamaha. I had it registered before I started this build. I have let the registration expire, but it's just a simple matter of renewing my tags at the dmv. Here is a picture of a stock ysr 50, and some ysr' and nsr's next to a mid bike, and my x 18 and ysr

i wonder if a honda xr 600 motor would fit in something like that

[sr20hardbody]

hmmm that would be interesting like a quadzilla 500cc 2 stroke motor that has pretty much the same angles

I know a guy put a kawasaki 650 in one, but he had to cut and widen the frame to make it fit.
It really depends on how ridable you want it to be. With a 200cc engine my ysr is actually lighter than my 107cc x 19. There is a guy on another forum who did an xr 200 in his ysr, and it would do 113 mph. That is crazy fast on bikes this size. There not much bigger than an x18/19 just bidder gas tank and rims. I'll see if I can get some pics of the really cool builds, but I'll start a new thread for them.
Back to my bike with the gearing that I have it should have a top speed of about 85/90mph. I could make it faster, but I want a fair amount of snap to it

how reliable to do you think this lifan engine will be?

There are a few around here that have been going strong for 2 or 3 years, So as long as I do my oil changes and check my valves it should be fine. My friend and I tore it down when it frist got there(he is a motorcycle mechanic) and we found no issues. It's almost an exact clone of an xr 200. with these china engines what you have to remember is to take it apart look for issues, and when you put it togther USE LOC TIGHT. Do your regular up keep, and they last fine. My x 19 has been going strong for a year now. Besides if it does'nt last more than a few year, It only cost me 400 shipped.
