Building a Classic 250 racer

I purchased a Harris Supermono and convert it to a GP 250 by changing the engine to a Rotax/FPE 256
The engine was purchased from a superkart driver and it is freaking awesome powerhouse in this 105Kg bike putting out 80-90 Hp
This is a fast forward in my process
From the ad to the engine swap
Now a year later from my idea things start to take form
I decided to change from Rotax cylinders to RCE and made adapter bracket for the engine
Then I cut and welded the gokart pipes to fit my bike
The fairing is Aprilia RCS 250 -86
And when the building process is done I will strip it and put final finish to everything and paint classic Aprilia 250 colours
Hope you like it

Hello what this frame

[@jostraka]

Hallo this is a Harris supermono 88-95
It was sold as frame and sving tank and glas and later production carbon faring
Fork is Suzuki rg 250 88
It’s a race bike from the beginning taking a wide range of different engines
Not that common my frame is #29
This is before Harris kept record of production

Any progress with this?

[@jostraka]

Yes I have today changed the cylinders to custom hand built RCS cylinders
The pipes is finally ready and now I am making the electrical (egt and ignition system)
Sadly I have a hiccup in my building due my sick mother
I will get back building when I have solved my private issue
Thanks for asking
Kind regards Jonas
