2005 RM250 Build
« on: March 20, 2013, 11:50:51 AM »
I bought my RM250 on May 16th 2012, I moved up from a clapped out 1998 RM125. I paid $1400 for the 250 and that was one of the best days of my life to finally have a "250". I was never very bike intelligent, i just rode the things. But I've always wanted to do a build and learn how to maintenance my own things, So after 8 or 9 months of no proper maintenance I got my bike back and the shock was blown which gave me the opportunity to finally rebuild it without worrying about missing a day to ride since there so scarce for myself. So here is my journey.... P.S I care about my bike alot thats why shes always clean and shiny but i had a choice between oil change and maintenance or go ride? And lets be honest, I'm going riding haha. I only rode maybe once every 2 months.  ;D ;D ;D ;D

Huge thanks to [cnrcpla] for all the questions I had! Thanks Buddy.


Checking out the Pipe and Silencer!


P.P.S - I got my wisdom teeth pulled the day before thats why i'm all over the place. Mouths killing me and the pain pills don't do crap.




Here she is awhile before the rebuild.

My brothers dad put the bike up for me and just power washed it and put it up so she started to rust, needless to say i was pissed.

Can't believe I let it get this bad...

My first engine pull :D

Before:

Starting to clean the engine and cases up

Afterwards, Huge difference

All the reeds were melted, the bike idled very high

My first time opening the engine, I was very excited.

Rebuild time

Cylinder was in good condition

The new piston


Put everything back together

New chain and sprockets

New MX51's

Rear:

Before and after

Old ones:

New parts from motosport

Fresh grips

Cleaning up the swingarm

Ordered a new chain slider but it didn't come with washers and i have no idea where to get them.

New silencer

New pipe

Greasing them bearings

Forks are leaking a little bit

Found a circlip while cleaning up, hope to god its the old one

My workspace and pimped out lamp


Anybody know what the hell this is and where it goes? it seems to go on the carb but the bolts don't like up and there's none on the actual piece

that is the throttle position sensor. I've never messed with mine. Break out your manual and put it on correctly.....
Good job on the cleaning.
In the picture of the right side of the motor, the powervalve actuator, is that round disc piece on backwards? It looks like the backside is facing out? If I remember right, mine has two cutouts on it?

I'll pull the cover off real quick and check, it fell out when I spun the engine around so maybe I put it back in wrong.

First time I did a top end, I had the bike all back together, seat and fuel tank on it was hot to trot. I pulled my shorts up to sit on it and kick it over and I felt a circlip in my pocket. Pulled it alllll back down had to buy a new gasket cos the sealant had set (mega pissed) only to find that it was in fact the old one :D Wasn't happy... Hey don't throw those circlips away by the by! If you ever need a pin for something around that size they slot through and you just bend em up. Fantastic stuff cos they are strong steel too!

I'm not 100% sure, but with Pro Circuit it has the factory finish of raw metal and weld marks instead of the platinum finish. Maybe someone else can fill us in as i'd also like to know.  :D
