Polini box or bbt? what will go better with 62mm crank and timings +- 175/125? regards

thanks for your reply angeldust : 26nm is amazing congrats I like RR box but is not switable for this Project, i agree. i see in fórum one engine with pinasco magny cours and crank 62mm and 23 hp and good curves but can not find it.... the is some dyno with bgm and crank 62mm? regards

i want to build engine base in px125 cases. is to carry pav40. 1 or 2 person I wanto to use Pinasco crank 62mm , box exhaust and carburator S.I 26/26 or maybe S.I28. I allready have pinasco flytech in engine. i need you help to decide to choose good torky cylinder. in my head i have this: - pinasco magny cours : will land in +- 126/176 timings. i allready made one in 60mm crank and is really power in low and medium rpm - Vmc stelvium : really power in medium and high rpm in 60mm stroke. will have good timing in 62mm stroke - bgm 177: never install - malossi sport: never install what you choose? why? if you have dyno fantastic please show!

hi what the squish should be use? the rx190 has another head. plug and play a have 1,4mm squish. the magny cours with another head uses 1,6mm squish someone have compression infos?

Thanks. Is normal with quatrini m1l60 and big bertha the shock it in manifold?

in my gs150 i have spring 33% 180mm (-10mm from original) and SIP 100psi. i have 110kg and for me should be litle more hard , because in strong brake goes all down easely. regards

Lol... can i meet him?

I'm confuse. So what goes wrong in the 2 solution? Motorhead how is your system?

hi use original gears with christmastree 20/17/14/10? maybe not possible. for exemple 44teeth in this engine is 92mm diameter. in other engine that use 22 teeth it work with 44 teeth but 97mm diameter...

hi i have engine with 10-15-20-25 cluster and with 44 teeth in 4 gear. i like to know if there is 4 gear with 92mm like 44 original but shorter, like 46 teeth and same diameter? what you suggest to use in combination with big bertha? the cruciform is 50,00mm. can i use 50,2mm ? thank you
