love it, have fun!
I can’t use it at night - no lights - the legal size number plate is on the back of my hi-vis jacket - the Speedo is built into the SPA tacho - the horn is a warning horn from a desktop computer - tyres are road legal. Amazing what the U.K. MOT allows on older vehicles.

Might fit a number plate though - don’t want the Police taking too much interest in the bike !

Although working in legal grey areas as far as I can see it is all actually legal.

Cheers
Paul

My scooter uses a Honda 900RR front sprocket and mill one side down to align. That will be a power wheelie bike with that gearing. Be safe.

Thanks for the warning - I’ll re-gear it if necessary.

Hi Damo,

I used NK Racing brackets and Harris foot pegs and levers.

I don’t know the settings - I’ll have to see if I can grab them with a laptop - the settings are specific to this engine though so might not suit your engine - I know the PV’s aren’t fully open at maximum RPM which suggests the exhaust port might be too high - I didn’t do a porting map so I don’t know what Daz did to this engine - he certainly achieved a nice power curve.

Cheers
Paul
