Bike is my brothers ride and it's former Team CAS Honda GP bike ridden by a Finnish rider Jussi Vehviläinen in world championship series back in 2002. Sadly the most of the factory parts are gone, but the bike still has a really cool history. It has been my brothers ride for a ten years now and it has been ridden hard with very little maintenance over the years. The plan is to rebuild the engine and restore it to its former glory
This is what bike looked before rebuild started:
This is what the bike looked like back in 2004. The goal is to make the bike look same again

We got new plastics kit for the bike and applied graphics on them. We where also able to find a used airbox in a good shape to replace the old broken one.
Engine waiting on the floor to get rebuilt and cleaned
The Shop
Is there anything special about the frame other than the skid plate mounts?
I started to dismantle the motor today. The clutch seemed to be in a good shape
The piston looked pretty toasted
The cylinder seemed to be fine
The mountings were welded to the frame by the factory.
More knowledge about HRC frames i don't have.
I'm excited to see this project finished !
I used a fellow vitards system to store engine bolts
Carburetor soda blasted. I need to get new gaskets for it before I can put it back together
Frame washed with alloy wheel cleaner. It worked really good and the frame is now fairly clean
Keep up the good work, it's coming along nicely.
Got some more work done to the bike.
Removed bearings from the cases by using a electric stove plate. After 15 minutes on the stove the bearings just drops off from the cases almost without any assistance.
Connecting rod was replaced with new prox unit in a local machining shop
Soda blasted the engine cases with my Mcgyver style blasting cabinet made from cardboard box, duct tape and clear plastic bag.
Got some parts for the build too. Used reed valve block from a friend with almost new reeds and red seat cover from ebay.
Pit Row
Some more parts arrived too
Rebuilt carburetor with new gaskets and breather tubes
looking great so far. another welder to the rescue. the world needs more welders.
you know this bike needs a video when youre done,right? braaap
Bored exhaust bridge lubrication holes to new prox piston
Soda blasted engine side cover
Continued assembling the engine
Does it help or stop the problem if drilling holes in the piston ?
Nice Bike!
The exhaust pipe on the bike is made by Doma Racing
JMX82 do you know where I could get a Doma and have it shipped to the USA?
Nobody over here carries them and I've tried contacting the company with no response. I'm not really happy with any of the American pipe makers for my 02 CR 250 and I tried the DEP pipe and it made a lot of power, but was pipey and not a lap time powerband if you know what I mean. Who do you buy your stuff off of? Do they speak English? Any help would be much appreciated !
I'm sure someone will ship the pipe for you in the US. Here's some web shops who are selling Doma pipes:
