I recently bought Mark's (parky69) MC21R, he's certainly been busy & its already modified heavily (see garage). Plan to convert from road to track bike. The engine feels + sounds very crisp, recently rebuilt by StephenRC45, flywheel lightened & also the barrels were decked according to Mark. I've not had chance to ride it yet , with a month overseas straight after buying it.

The ultimate plan:
HRC Race Wiring Loom and HRC Delimiter (ignition advance??)
Convert to Pre-mix
Remove standard Air Box
Run Open Carbs + Carbon Box Shield (from Andy)
VHM Heads
Triple Core Radiator (with modded cap to clear RVF forks)
Billet Top Yoke
Ohlins Rear Shock (gotta love the sublime anodised gold springer)
Mag-Teks (if I can find them)
Tyga GP Race Fairing
Maybe some Stainless Chambers and maybe a RS250R Carbon Seat / Tail Unit (I'm going to look at Si's, which will probably swing it!!)




A few choice bits from Yahoo Auctions / OkShon, not all will be used. Maybe fit the JHA Trumpets - Airbox lid to my MC21SP.

I'm working overseas for 6 months of next year, so expect this will be a slow-burn project.
