Default 1993 CR250 Revamp into a '96 sudo McGrath Replica Project... Part II

     

Well I had started a thread on this bike last year in hopes to keep adding to it as work on the bike progressed,... unfortunately you can't reply to threads that are over 300 and some odd days old ....

So here's a link to the original thread:

1993 CR250 Revamp into a '96 sudo McGrath Replica Project...

So,.. it's been a while on this one,.. but I've actually been wrenching on the bike a bit here and there over the past couple of weeks (After not doing anything all summer )

The push is on to get some of the smaller projects done on her before we go to "Flat River" on the 21'st,.. Even my Brother in law brought over his '91 YZ250 (That I gave him..) to work on



Things on tap for next week or so:


Install the new PWK Air Striker Carb and new throttle cable -





Re-Install rear shock that's just been worked over by BBRMotoSports





I've got new springs for this freshly rebuilt shock as well as my forks ... so that's on the list as well..

More to follow soon (Hopefully sooner than 314 days! )

Rick

Yeah,.. I'm trying

Well I got a late start this evening,.. but I was bound and determined to get something done on this bike,... we had a beautiful day here,.. high of like 71 - That in it's self is inspiring in light of the 106 deg. temps we had for like 12 days straight a short while back

So now on to business...

The front end is all done,.. New fork springs are installed and preloaded correctly,. new cables are on along with bark busters. I even lopped off my levers and cleaned the ends up nice n smooth. Grips are on. Throttle tube and housing is cleaned and re-lubed with graphite.

Here's some pics of that area,... let know if you see something amiss








One thing I did noticed when I was standing at the rear of the bike was that the left radiator looks a bit tweaked or "Diamond" out (??) ...



Radiator Question: What's the proper thing to use in it?... looks like there's a mixture of Water/Antifreeze in there now,.. you guys running anything "better"? ... different cap?

I was also able to get the rear shock spring installed and mounted the shock,.. pics of that tomorrow,.. It's sleepy time for me

Thanks
Rick

Nice Rick, just like Dogger said, keep that thing going. I cant see anything wrong, did you get new cables. I have a bearing billet throttle tube (by MSR?, i forget). nothing beats the feel of new clutch and throttle cables- love that quick snap back feeling.

had mine out today, finally dialed the jetting- coulda been the great weather.

any ways, was good to break in my new Tech 8 (now i am just gloating). and i'm supposed to be broke...

Yep,. new cables all around,.. but I'm going to have to research the throttle cable thing,.. the MotionPro one I bought is just a bit too long The factory one has an additional adjustment in the middle of the cable so I'm thinking I may have to buy the Factory one or find out if MotionPro makes one that's about a 1/2" shorter..

Carb - I ended up snipping off about 2-1/2 "wind's" of the Carb slide spring to keep it from binding up internally,.. but now the throttle doesn't have a whole lot of tension on it,.. I mean it snaps back fine,.. but there's not a lot of resistance twisting the throttle back,.... which is not good as I think I'll panic reving this thing a lot here in the near future

Good progress so far.

Now I see what's going on with your throttle cable problem. Your
throttle is not the OE whirpool style throttle. It looks like a
conventional pull style from a 92 or earlier bike. If you are
using OE 93 cables, you will have trouble getting all the slack
out of the line - which explains why your adjuster is just about
used up in the picture.

I use those too - Pro Taper for me. Can't beat the feel. Only
problem in this case is I'm not sure if the bark busters are
compatible with them.

Really!,.. that's just about par for this course I'll tell ya!

I guess now I have to decide on if I want to try and find the correct cable for the assembly I have,.or just get a whole newer / better assembly.. ??

---------- Post added at 05:04 PM ---------- Previous post was at 04:41 PM ----------

How are those Motion Pro Vortex throttle assemblies?.. looks like they're all over ebay for like 30 bucks shipped,.. I would imagine that my new Motion Pro cable would work with it as well ?..

Nice work. I see you're a Bellville guy. Ever race with The B.E.T. boys? I survived a few of their TT's. Be careful at St Joe.....

Yeah,.. I was a member out there and raced out there ,... TT Open Class no less ... I was running a hopped up, tricked out XR600 back then (should have kept that bike!) ...

St.Joe - love that place,... Nice wide open blazing fast trails,. We can fly through there like nobody's business .... Well be taking it easy this trip though as none of us have ridden in a while,... And it'll be my first big ride on a pinger
