SO Ive got some updates
I just "finished" tuning my 70cc 103, and I learned some things (my other 2 are 50cc's)
Specs
stock cases
Doppler crank
new bearings and seals
small port 46mm Airsal
carbon fiber Airsal reed block
19 PHBG
47mm LC head using thermosyphon
xk80 radiator
stock vario 2xstar washers/3balls/starter clutch shaved wayyyy down/lightened weights (weights were fixed to the vario arms)
ax32 belt
stock gearing
Le Partie CDI timed 1.1mm btdc
stock Le Partie box, no curve
Polini Utah pipe
Ill include some pictures later, but, I get what Jesse was saying about the stock clutch having some issues when introduced to real torque, when I swapped from the 15 sha to the 19phbg, it opened the bike up. Now my full jacket LC50 103 does about 47mph, but it does not have this kind of pull off the line, I def felt the starter clutch catch the bell a bit, so maybe this bike will get an ER3 just to eliminate that issue
That said the bike rips, fuck air cooled heads on French bikes, get you an LC head and never look back, compared to my 46mm Parma head, its night and day with temps, as of now the bike is done, but its pretty cold here, so maybe next season Ill have to re-jet it, and Ill be able to do a proper speed run, but Id give it 50 easy with stock gearing
Up next is my full LC 70cc 103
Texniq cases
stock crank
45.5mm Malossi LC jacket
Le Partie CDI
Ninja pipe
19 Polini CP
Athena reeds
thermosyphon cooling
Stock vario vario 2x star washers/3balls/starter clutch shaved/2x m6 nuts on each vario arm
ax32 belt
Polini spring
stock gearing
Im going to start building it this Saturday, shouldnt take to long as the case/crank is already together, if the above bike doesnt break a stock vario, I have a feeling this might (edited)
