The 175 is basically a 125 motor stroked (same bore). Then the 200 is the 175 motor bored (same stroke). IIRC.

It's never too late to have a happy childhood! I'll founda vid of me a few years ago riding it. Can't even get into the powerband. But it's got OK low end for a mini. http://youtu.be/TML6GY5aiCM http://youtu.be/TML6GY5aiCM

"You think it's fast now? Swap an 81 YZ80 motor in it... " I kept the 60 lower end. YZ80 top end bolts right on. Lightened the crank, stuffed the cases, installed internal rotor YZ80 ign, did a ton of cylinder work, running a yz80 pipe, reeds, carb, ... more »

Hahhh! I thought that looked like a 3R0 front fender! Yep, ebay may get you some cash for it. You could also try Marks Vintage MX site. That's always great for making connections with similar owners. Where did you get the new plastic? Are you going to ... more »

These truely are great little bikes. I've got a 1980 YZ50, 1981 YZ60 and a 1983 YZ60 that's modified to keep up with modern pit bikes. I ride my 1983 all the time, following my kids around. They do scream! Plastics are somewhat rare, but easier to find ... more »

Still there... North of the highway, west of town. Looks like K-9 Kampus is right in the middle of the track. Looks like some of the track is still there too.

I wonder how many VitalMX'ers are zooming in on Google Earth right now. That track looks amazing. Would be cool if it weren't all condo's by now. Someone post a pic of the area please.

My first real job was in a machine shop. Took machining in high school too. Machined and welded for years after school until the US Army got ahold of my 19 year old drunken ass. I was making good money and having a little too much fun! Now I'm an engineer,

Whoa! That swingarm is sick! Does anyone in the rest of the planet use that terminology? Sick Dude! That means like Touched, like Mental, like Wicked Pissa.... Tooling for that thing would cost 5-10 times what the actual piece costs I bet (including

Hey Mike. I just PM'd you. Need help with a similar build: Thinking about 175 crank, top end, clutch cover in a '82 YZ125 motor.... Any thoughts?

Nice build! I always wondered if I should look for a newer chassis for my '87... She's a tank!

For $150 you can't go wrong. You may find that the best route to a restore or rebuild is to find yet another one and combine the best parts. Take your time and take it apart and evaluate it before hitting the "buy it now" button a kajillion times. My

Looking great! But...What's up with that blob of crap on the stinger??? Very uncharacteristic of you Nate! Oh, and Happy Veteran's Day Sgt. Hubbard!

This is the bike that was mentioned in Mike P's '77RM125 thread, so I figured it was worth a mention in this thread. It's clean and has some goodies on it. I think the red anodized Emler stuff is reproduced. Not 100% sure about that, but the boost bottle

That's a pretty cool bike ya got there Mike. The colors confuse my eyes a bit but maybe that's just because I'm used to seeing a little dirt on a dirt bike. I have no idea why that other '79 YZ125 is going for so much. It's clean but mostly stock ho-hum ... more »

Those are both very interesting designs! The Moto-X-Fox head was the hot setup for '79. Yamaha used Fox's porting updates for their national bikes. Thanks for the eye candy! Hope someone on here gets them!

Mine has a piston in it, so not an emulsion rez. A bladder or piston rez from any other shock will work in theory, but keep in mind that the volume of the rod is what's being buffered. The YZ shocks had a lot of piston travel compared to newer designs, ... more »

Beautiful resto O44. Too nice to ride! I've only made one bike too nice to ride and I can't do that again.

Thanks for posting the pics Husky. Good times!

Yeah, definitely post up some pics of your 125f on this thread. Did you have any hot setups on the bike? Back in '79 I was still riding my Tecumseh powered Sears minibike and dreaming of having a real MX bike to ride, so I don't know as much history ... more »
