Yeah I'm sure it's an L or an M - it's the same frame I've always had. I'm picking up a complete B12 motor with switchgear / carbs etc next weekend so may just whack that in save some pennies up and go to the house of power. Then flog the 750 motor - who knows.
I went, I've got some pics but they're too large to upload. I can't resize them ad I'm only on my phone. There wasn't a massive turnout about 8 Kats turned - the most I've seen in 1 place. If you want to send me your email I can fwd them to you.
