1992 Rm125 my first love

My first bike was a 1992 Rm125N. Bike was in decent condition when I initially bought it, I tried my best as what a 16yr old with no fixed/disposable income could have maintained such a machine. In 2005 I bought a 2005 Rm 125 and was completely blown away by the performance and general feel of the newer bike. After much contemplation I sold the 92 to a good friend who really was interested in MX and I figured id help him get there by offering my bike at a decent price. Boy did that hurt to let that go , but I told myself its better off as someone will enjoy it as much as myself. Fast forward 12 years I now own 4 bikes. the 05 Rm125 (Cylinder mods by EG) 08 Rm 250 (full engine mods by VPE), Rm85 110 supermini and a 05 Rm85. I have since aquainted myself with all the manuals, tools, and other information needed to maintain my Rm army. I always think of how my first bike could have been easily sorted out ( jetting,suspension and engine) with my gained knowledge.

The 92 within the 12 years changed 9 different owners, all of which could not give a f**k about maintenance. The bike circled its way back to my door step as the newest owner came to have it repaired. After an overall assessment everything was bad. EVERYTHING. Owners ran with torn airfilters, rad pump leaking -engine efull of water, all bearings shot, shock empty- bladder torn, forks empty, spokes missing, wheel bearings shot, top end  0 psi , reeds  gone, air filter cage missing, NO CARB- I was told they were using a Chinese scooter carb. The list goes onn and on. LOng story short ,parts list exceeded 1200 bucks. The new owner was flabbergasted. How could a 500 dollar bike need so much in parts alone??

His plan was to sell it to a parts shop as scrap. This was my baby I could not let that happened. ..I bought it at $400.

Hopefully I can complete this rebuild completed. Long expensive road ahead but im sure its worth it (well to me atleast)!



Fast forward 12 years later, it looks similar but..


After I bought it, I started tearing it down. I honestly felt hurt





Leaking Rad pump with bad worn impeller  and seized bearings! Water was sitting in here for over 3 months




Bad bearings , Lots of dirt in the intake





Whats this silicone? WTF seems the dumba$$es tried prying the flywheel off with a screwdriver and pivoted on the case.






Time to tear down and see whats up . No fork guards, worng number plate, wrong rear fender -airboot exposed at the rear. Rear fender attached with roofing screws





This is why you don't use this red silicone -gets stuck in all the important oil flow areas. Stick to yamabond or threebond!






Engine out, Removed epoxy at the drain. What a lovely crack that is. Id really like to know wtf they had to do that resulted in all those knicks. Any sugggestions?



Scrapped and washed. Will have these rust treated and painted before rebuild.




Engine split, These guys painted the engine with some sort of oil based paint , the Crank bearing doesn't run smoothly, nor does 3 of the tranny bearings. The gears seem in great condition, the jug is unmarked and looks good.








20+yr old packing, burnt out and like paper. It got cleaned, decarbonized and repacked with whatever excess packing I had layin around.


While I wait for parts I started cleaning, inspecting and polishing alum parts. These polishing .deburring pads from pryme MX are amazing, bit pricey but dam its really efficient. If onlyi can source this cheaper somewhere id get myself a dozen!





Now to carefully order parts and play the waiting game.

The frame has been dropped to PC and the cases has gone of to be welded








update

A bit of motivation . Got the frame and swingarm back from the pc guys. It looks gorgeous! Dont hate me for not hitting it with the suzuki  yellow. But after much contemplating i wont be going the restore route.its gotta look different. I opted for flat black. I wish i could have found black plastics for this



Engine cases have just came back. Parts are still on its way. It still needs to rinse a couple of times.






update 2

Rear calipers shot. Piston seized. Did full rebuild.fluid behind piston had alot of dirt. Not sure why as the reservoir was clean. Maybe never bled ?


Took out the fuel shut off valve to clean. Boy was that thing filthy. Cleaned out the internals as it felt gritty while turning. Flushed the tank as well. So much dirtt




update 3:
Had an extra nimber plate and front fenser off my 05 rm125. The fender fit perfectly no drilling required however thr number plate did not. The triple on tje 92 did not have the ears at the bottom to seat the plate nor did it have the mount at the top to fasten it. I fabricated a top mount and a bottom plate to accept the platr fingers. Took about an hour but i think i got it. Now the 92 doesnt have the square front plates or the square fender.



Some progress. Got the crank rebuilt with the hotrods kit. Good thing i did. The old bearing amd pin was in rough shape!



Still awaiting 2 tranny bearings. So why not work on swing arm. Truth be told. This motion pro  tool really kicksass. Well.worth my money. The spacers/drivers really hold the bearings straight.
