Fuck you would not believe the conversation me and Seymour had with Dave nthe ferry for the last BoB trip. Even I who would have a barn full was trying to convince him to sell some so he could finish the others.

Found the smog pump, photos attached. Glen it's yours as long as you use it. I also have a scooter carb somewhere off my Yam 125, CV type & electric choke. Will dig it out and check size.

Speedpro, i believe that type of pump turns CW and need buggering about to rotate CCW (disclaimer: intertube copy and paste fact)

Join the club Dave...
There is a couple of projects that I'd love to get my hands on. But alias NO... And they aren't even specials...

Everyone else would wreck them. . .

My little supercharger turned up today, nice unit. AMR 300.
Thank you Neil

Found this stuff while looking for something else down at the storage cow shed. My old thinned down Wade, FZR head and the new AMR supercharger. The FZR head was destined to be the beginning of a 100cc twin fourstroke SC, might still happen?

good your going to play with a real engine (-;

[Flettner]

How can you call this a real engine, x2 = 100cc. Thank you Speedpro for the FZR parts.

is that FZR rod and piston? 125 then

I suppose if you destroke it it will be perfect

New crankshaft, back to 104cc? What's the limit on SC 100 fourstroke?

[Flettner]

What would be a good frame to put the engine in? I'm talking cost effective ( cheap ).

3ln FZR250 would be easy and cheap, good size rims for slicks, room to lighten it, big enough for old men to ride

the rules are not clear on this
The maximum capacity for rebored engines shall be:
F4 2 stroke 55-100cc - 104cc
2 stroke 55-125cc air cooled - 130.5cc
4 stroke 55-150cc – 158.09cc
F5 2 stroke 0-50cc - 53cc
4 stroke 0-100cc - 104cc

100cc SC is f4 not f5
If you applied the +2mm method for max overboring you may well get a bit of a lift as the pistons are so small

on a std stroke 124.84cc
on std stroke +2mm 135.48

158.09cc it is then... Hehe 😆
