DISTRACTION AHEM...My twin is a 440 cc liquid cooled inline 2 pumping out around 130 HP at around 10,000 RPM. All modifications internally are unknown till I completely disassemble the engine. I know for sure it was V Force 3 reeds though.

Niiiiiiice. 2-strokes are insane.

Mine is a 487cc (nearly 30 cu in) inline twin.
4 stroke
Air and oil cooled
9.0:1 compression ratio
47hp stock
11,000 rpm redline because of valve float
Custom adjustable on-the-fly rev limiter 0 - 11,000 rpm
Twin 34mm Mikuni carbs
6" Autometer monster tacho
Performance stainless steel exhaust (loud! See pic)
Rejetted from 17.5-60-130 to 20-60-145
Larger than stock oil cooler
Soon to have uni filter pods
6 spd sequential gearbox
Wet multi plate clutch

Best pic I have of the engine:

BriggsTwins 11-08-2009 07:45 PM

Rotore 11-08-2009 07:49 PM

BriggsTwins 11-08-2009 07:49 PM


BriggsTwins 11-08-2009 07:49 PM
