Hey everyone,
I've been a lurker on these forums for the better part of a year, and finally decided it was time to post my build.
Here is how the bike looked when i picked it up 4-5 months ago
Was very close to stock, aside from the moose gripper seat.
Still had the original piston in it.
The front tire had cracks so big you could see the tube which was kind of interesting (I believe this was the original tire)
Had some very bent aftermarket garbage rads.
But she ran great and all the bearings were tight.
So i brought it home and began to tinker.
Airbox was cracked and the plastics were pretty worn so i replaced it with a set of 2015 plastics from Rocky Mountain.
Threw a front wheel from my 250f on to get me through the season.
Vertex Piston
Hammerhead shifter
Replaced the shift stopper with an 07+ version as the only thing left on the old one was the inner race.
Pro circuit Works pipe and 304 silencer
v force reeds
went up a tooth in the rear and picked up a D.I.D ERT2 chain.
Now the winter tear down has begun. Will update soon with pictures and the plan.

What did the plastics amount to from RMATV?
The Shop
The porting is going to be done locally.
CP piston
OEM Crank rebuilt with an OEM Conn rod
Stock hubs turned down
Going to get my OEM hubs turned down.
I have purchased a cerakoting kit and a small powder coating oven in hopes that i will be able to do that myself.
And a few other parts along the way.
I had a few parts and tools come in before christmas.
There was some worry after finding out that most of the shift stopper bearing was missing but it looks like the transmission wasnt damaged. Although the bottom end bearings were all either seized or barely moved. Ive opted to go to a local bearing shop to get bearings as opposed to buying OEM or buying a "bearing kit".
The shift shaft on the other hand got mangled, and actually looks to be slightly bent.
My brother got me a nice little Christmas gift
As a lot of this is a learning experience for me don't hesitate to call out if i'm doing something that doesn't seem right
Has anyone tried out the Motion Pro Vortex throttle? and does anyone know if an OEM black rubber cover will fit on it?
Merry Christmas and Happy Holidays!
The kit comes as OEM plastics and airbox. the only thing you need to buy is the front number plate and fork guards.
Fortnine sells the kit for $340 CAD delivered, will probably go that way eventually.
Got the engine assembled now its time to rebuild the forks.
I have the motion pro throttle and the boot that it came with is grey and cracks/falls apart extremely easy.....I was wondering the same thing about the OEM boot....please report if you try that route.
Cheers!
You definitely need to spill the beans on how you got that finish on the engine case! looks awesome
as well as a small eastwood powdercoating oven.
If you are sure to only get colors you are going to use those 6 should last you quite a while.
It's not too bad, racked up some time sitting in a shed unused and mostly been used for dirt track.
The pipe is all sand blasted but no dints...dirt track.
I swear the preload rings on the shock have never been touched...virgin.. So I'm guessing that shock oil is gonna be pretty rancid when I get into it tomorrow.
I will pull the clutch cover off too and have a look at the shift stopper seeing as how it's a problem apparently.
You reckon get a 2007 one as a replacement?
I'm gonna ride this bike for a while as is, then I will strip it and go through the whole bike.
Putting a new piston in it tomorrow, wanna go riding this weekend.
The cylinder is pretty worn. I will either go with a re plating job if it is inexpensive, or I will go for an Athena 144 kit.
Do you mind if I post my stuff in your thread...save starting another thread ?
Pit Row
Can you get to it by removing the clutch cover and clutch? I haven't had a look yet. Went through the back end of the bike today, serviced the shock and linkage.
Linkage bearings are ok but the seals are damaged.
Swing arm bearings and seals are bad but usable for now as was the bottom shock bearing.
This bike seems to have never done motocross , the shock had definitely never been apart , yet the standard oil wasn't too bad and the shock doesn't look worn inside and the valving shims don't seem to have worked very hard.
I'm hoping that since this bike has done mostly dirt track, which doesn't have the shock and strain through the transmission that moto does , that the transmission won't have any significant wear
All I've done so far is change the fork oil and seals, strip and service the shock, all the linkage and swing arm bearings and a new piston , other than that just general service, new sprockets, chain , chain buffer and chain guide.
Pulled the clutch cover off today and everything was sweet, original shift stopper and all!
Clutch basked not very badly worn, fibre plates are a bit thin, steel plates don't look worn at all
At a loss to explain why it's so hard to up shift at full throttle, even slapping the clutch...the internals, primary gears etc look pristine.. Won't know til I split the cases I guess. It could just be poor technique on my part..Havent ridden in 3 years
In any case, I won't be tearing it down to start the rebuild project for a fair while yet...not unless the crank goes..it seemed to have a bit too much side to side movement..worn thrust washers...
I'm stunned at just how strong it runs as the cylinder is quite worn , especially below the exhaust port and on the exhaust port bridge
Just going to cane it , and get my riding back up to scratch.
These are fantastic bikes and I think I may have landed a bargain
Bent shift shaft maybe? You can replace that one without splitting the cases and its a relatively cheap part. if it still shifts poorly you probably should consider splitting the cases and replacing shift forks.
How does the shift shaft usually get bent? Taking a hit on the gear lever or something else?
Shift lever looks original but undamaged
