1979 RM80N Roach

Hi Alex, took some pics of my RM125B and 100% original CR125RZ (like your B it has everything original and in great condition incl tyres and sprockets etc) - I'm actually having trouble uploading the pics here - isn't it simply using the insert image button? My second 125B is a bit rough and needs work. I don't have the home workshop and time atm so thinking of sending it away to a dealership or find a restoration workshop to give it a bit of spit and polish - just enough to take out on weekends. Looking forward to seeing the bikes once the tanks are on - fantastic job!

Thanks for the reply's fellas... the little fella loves it and can just stand up on it on tippy toes.. may have to drop the forks an inch.
Mal, you have to use a hosting service to upload pics.. such as photobucket.  Easy enough but a pain.
Cheers,
Alex

You have  good eye for detail, great work mate

Thanks fella's on the positive remarks.  Well, when i picked up the tank for the B from Rod, "RedAlert", he also had the tank and front fender ready for the N.  What i job he has done.  It has come up perfect.  He used the same Rolls Royce match that is identical to the OEM guard i provided.  I fitted everything up this morning and also connected the carby properly and installed the pipe.  All fitting up nicely.  The right side still needs some work as parts are coming to finish off the clutch and a few other things. Then it will be ready for tuning, testing and running in.  Young fella saw it and had a grin from ear to ear.  This bike has been rebuilt taking into account that it will be ridden by the young fella.  New airfilter, new rod, all new bearings and seals, rebore, piston and rings, new rear shocks, rebuilt front shocks, new wheel bearings, chain and sprockets, chain tensioner etc...
Big thanks to RedAlert for the great job on the tank and front fender and everyone on here for input and support.

How cool is that! Well done.

[alexbrown64]

Thanks mainline... my boy loves it and it brings back memories for me too. 
Anyway, i finally finished the rebuild today.  There are a few small tweaks and adjustments but overall its finished.  Yesterday, i got it back together but there was a problem with the tranny.  I kinda thought there would be as i knew my shift pawl wasnt lining up perfectly but didnt realize at the time that i could adjust it.  After some serious thought and stripping it back down, i discovered the set screw that has a cam on the back but i have never noticed without my reading glasses.  Pic of problem below...


And the set screw that is cammed at the back but i never noticed... well, i adjusted the pawl using the cam on the set screw and got it aligned like the pic above.. Here is the set screw showing the cam section. Its only 2mm but makes a huge difference.


And finally, below is a pic as its sits after i took it for a test ride in the park next door.  Run it through the gears and it is like butter.  Clutch works great and motor is tight but great.  Started 4th kick and idled well and has a nice snap and sound.  The last things to do is a fix the steering lock as the forks touch the tank, shim the top mounting bolts of the shocks as they bind slightly and then just go around and loctite nuts and bolts, check everything over and give it a good wash.  Then it will be ready for running in and more checks.
Cheers,
Alex

[FourstrokeForever]

That is an excellent resto/rescue Alex. I hope the little bloke appreciates what he has and treats it with the respect it deserves.

[shelpi]

well done mate, top job

[alexbrown64]

Well, this project is finished.  I made some final adjustments today and now she starts first kick and runs like a beauty.  The boy loves it and will take it for its first ride soon.  I have taken the final pix of the old girl completed.  Hope to look after her and have it for many years to come.
I have installed an hour meter to keep track of the next 36 years.  Big thanks again to RedAlert Rod who did a great job on the tank and front guard.  Here she is...
