new guy from mi!

hey guys, just found this site. never really got into the dirtbiking forums. never had a reason too.

but. im the proud owner of a 1982 yamaha it 465, have had the bike since i was 13.. im 26 now.


and now a 1980 yamaha yz465. bought the yz as a parts bike, since i blew my it motor to smithereens

so, im tearing down the yz motor since its a 4 speed, and had a cracked case by the kick start *go figure* and replacing it with the 5-speed trans, and the clean case from the IT..

which leaves me with a perfect yz465 roller. no plastics, tank, or seat.


My plan for that. which is one of the reasons im here, on a quest for research! im going to super moto it. tryin to find info on what newer motors, and what street bike wheels would fit?

then my street bike. a 2006 ninja zx6r. some light mods done. nothing to fancy.


ANYWAYS! back to the questions at hand, now that im done being a whore! anyone know what street bike wheels would work? any change of forks i should do? whats an easy to find, cheap newer motor i could throw in the yz?

To get a decent street front end (ie, disc brakes) you would probably want to swap out the whole (wheel, brake & fork) assembly.

I think your YZ still uses loose ball bearings in the steerer tube, so the first thing you will want to do is install a tapered roller-bearing kit.

416238 QUANTITY: 1 Kit

DESCRIPTION: Steering Stem Bearing Kit


YZ465, 1980-1981 Bearings~q=tidaa3292zz~r=~

Then look for a steetbike fork that has a steering stem with the same length and diameter as the YZ. You may have to go to a breakers with your YZ lower triple clamp to match something up.

For the rear wheel, keep an eye on axle diameter, sprocket size & offset, brake assembly, and rim/tire width.

I think any IT/YZ465/490 motor will drop into your frame, just make sure the exhaust fits. Anything newer would probably have water cooling, radiators, etc.

But before doing all that, consider that your roller may fetch a decent price on fleaBay. :thumbsup:

Good luck!

honestly never really thought of ebay, are they pretty hard to find? my buddy has like 4 of them running and riding, as well as 250s and a bunch of good parts bikes.. this one was actually one of this running riding ones, until i talked him into selling it to me after the case cracked.

I'm not saying there is a lot of money to be made in selling old YZs and parts, but there is a pretty strong vintage racing fraternity out there that loves the older YZs. Australia seems to like them too.


So naked sitting next to each other!

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      Hey guys, 
      I've used this forum as a "guest" for awhile now and I thought I'd share my build now that it's all coming together.  The primary purpose of this project is to help me train for roadracing my 2009 R1 at lower speeds as well as giving me a cheap alternative to racing the big bike. 
      Here's what she looked like when I picked it up from a local shop.  Paid $800 cash for the bike as you see it with 17' rims, FMF pipe, EBC 250mm front rotor and clip on handle bars.

      Fits PERFECT!

      Shake down run at the Herrin Compound last summer:

      As she sits today:

      i bought my yz125 from a dealer and they said that the clutch was broken so i bought it and it worked fine it would run move and everything and then it started to act up and now only first gear works barely though. when you put it in first it acts like its bogging down but its not and when you go into gears 2-5 it wont move i dont know whats wrong with it im assuming the clutch is slipping or something if you know please leave me a comment

      Hey guys, I have a 2003 cr125 I bought a couple weeks ago and I'm having a problem with it. The spark plugs die every about 15 minutes, with hotter plugs it will last about 45 minutes. I herd that if the timing is off it can over heat the plugs and burn out the the resistor. Is there any truth to that? The reason I thinks it's not fouling is because when the plug dies it gives no spark no matter how much you clean it, And it shorts out.
