Looking at my 125J, I would have to make a governor cover plate and eliminate the water pump. This is easy stuff and can be done with regular people's tools (I'm a machinist but sometimes I revert to the die grinder and hack saw when I don't have access ... more »

It's right side ignition, right? Spins clockwise? If they're on the same side, then yes. Yamaha has used the same backing plate mounts and shaft taper forever.

I'm not sure, but being a yamaha, it's a good chance. Take a look into partzilla and compare shaft end bearings and such...

If it were me, I would look into using the IT motor, cases etc, and drop the YZ125 close ratio trans into it if possible. If you want the 175 motor to wring out like the 125, then you will need to raise the exhaust port a little and rework the head for ... more »

Which rod is longer? If the YZ rod is longer, you could keep it and make a spacer to lift the cylinder so the piston meets the deck of the 175 cylinder. Or mill some off the top and bottom of the cylinder to get correct deck height. You'd have to adjust ... more »

Amazing work Heck! That pipe looks absolutely gorgeous!

I think his bike came out a little cleaner than you're KDX, Sir Roostalot! That's a great war story.

Looks great! I just picked up an '82 myself. I think the silencers were different between those years... Different placement of the pipe-to-silencer joint. So I think you lucked out with that purchase!

This may be the sad truth. I didn't think about that when I started my ornary rant.

Added reply in a thread 90's bikes? 4/13/2015 4:44 AM

That's a great point. The reason I started this post wasn't to stir the pot or be a troll. I guess I was just looking for some convincing, since a lot of bikes I see on here just seem "new" to me.

Added reply in a thread 90's bikes? 4/10/2015 8:17 AM

All good points except that I'm talking about 90's bikes, not that '87 that you posted. IMHO, this '95 YZ125 isn't much different (looking) than the 2015 that you posted. Minor tech upgrades...Smaller bearing here larger axle there, wavy rotors and new

Sorry for the rant. I do get it and I do realize that my avatar is me on my Mono shocked, disk braked 490. AND I just bought a 1982 RM125. My first liquid cooled bike in 20 years. I guess I'm just nostalgic about the 70's and 80's when most of the really ... more »

Started new thread 90's bikes? 4/9/2015 8:18 PM

Really??? Can we make an OLD SCHOOL MOTO forum that doesn't have Liquid Cooled, Single Shock, Power Valved, double Disk Braked bikes please? There has been no innovation since 1989. None! Just "refinements" and cheater 4-strokes with twice the displacement ... more »

I did drill the reed stops. Having no access to a mill at the time, they came out OK, but not perfect. I worry about the reeds opening too far and fraying from hitting the insides of the reed cavity. I guess I'll have to see what it looks like when it ... more »

I dug out the old RF Boost Bottle out of the spare parts bin and cleaned it up a bit. Thanks to Fastguystuff for making these decals too!

I also roughed in the Boyesen ports a little more, blended the transfers and re-aimed the secondary transfers. ... more »

Added reply in a thread Just picked up a kx 125, what do you guys think? 2/24/2015 10:11 AM

Looks like a new bike to me... Nice score, but is that really Old School??? OTOH, I guess I'm just being cranky. It's a two stroke and we need to support our fellow oil burners. That is a sweet ride.

Added reply in a thread YZ125 1979 Race build 2/4/2015 9:45 AM

That's definitely it. Thanks! Only problem is I don't have a cool WB sticker that says "Monoshocks" underneath. Actually haven't seen one before, but now I see it in the old school picture too.

Added reply in a thread YZ125 1979 Race build 2/4/2015 7:49 AM

Yeah, the LOP YZ125 pic that I posted on PG1 shows a WB sticker on the rez. Guess I'll change the sticker over to be period correct lol!

Added reply in a thread YZ125 1979 Race build 2/4/2015 6:20 AM

LWC307: Does this rez look familiar to you? Thanks for the post by the way. Maybe it's a LUFT after all?
