Hi everyone,
Here it is, taken 18 months to get it this far(could not have done it without the forum).

Whats been done,

All body panels+tank(original), repaired,primed and repainted Rothmans livery, special thanks to TYGA for sourcing the original decals.
Showa front forks stripped down, externals refinished,new oil and seals as per forum instructions.
Rearsets stripped and rebuilt, not original parts, matched what I needed from a old fireblade.
Rear Maxton shock stripped and rebuilt.
Head bearings replaced.
Top and bottom Yoke stripped and refurbished.
Engine Rebuilt topend and bottom end (really sweet motor now). Thank you Andy for your help with the crank seals and bearings.
Carbs stripped and cleaned jetting left as it was.
Airbox modifyed
MMax box
Tyga Stainless steel chambers with carbon kevlar end cans.
New Screen(M&P Accessories)
New Chain and Sprockets
Clocks from a MC21 (Reservoir Cogs)

Theres loads more just cant remember.
Fine Tuning done by Royston Edwards, Caldicott.
Dyno Result as follows:
1st Run
50.32degrees F, 30.01 in-Hg, Humidity: 46%, DIN 0.98, Max Power= 59.94bhp, Max Torque 27.68.
2cnd Run.

Reading the forum I felt this is not a bad effort for a first try, I know there are more upgrades to do, but now i have a Rothmans MC21SP running really sweet I am interested in any comments you guys have.
I am also looking forward to meeting you all at LLandow if you go there this year.
Lok foward to your comments

Best Regards
