I’ve been wanting to get a 2 stroke project for a couple years now, but could never find a bike for the right price and that’s not too roached, but back in august of last year I found this 2002 rm125 that supposedly just needed a fresh top end.
Before we started tearing the bike apart we completely remodeled our garage, which dragged on forever.
The garage took us way longer than planned so the bike sat in our basement for about 5 months. Im in my sophomore year of high school and for my environmental science and stewardship class I have to do a supervised agricultural experience (SAE), which is an all school year long project that is a pretty big part of my overall grade. Luckily for me I am able to do this bike as my project! I’ve been able to partner up with a few awesome companies like Wiseco, Motion Pro, phat head racing, USchrome, reverend motors, specbolt, and firepower. I know this is the last month of school and now do to the Corona virus it’s turned to online school so I’ve finally decided to make a vital Mx post. Back in January I finally started tearing the bike apart.
So then my dad and I started tearing the engine apart because we are doing a complete engine rebuild with a Wiseco garage buddy rebuild kit.
The whole top end was completely clapped! So I sent the cylinder head off to Phat head racing and the cylinder to USchrome to repair it.
These billet Phat heads are definitely a sweet part! Turns out the cylinder is actually bored out to a 134.
So now we have the whole engine apart and the bottom end looked like it was still in pretty good shape. It’s been rebuilt before because it had a hot rods crank.
I’ve also powder coated a bunch of parts.
The one radiator brace came out really bad the first time but then I just sandblasted it again and soaked it in acetone and it came out perfect.
While I waited on different parts to come in I cleaned up a bunch parts I’m keeping on the bike.
Currently we are rebuilding the engine and I’ll upload pics of that as we go along.
