i have cagiva mito with rd engine....can i have a same setup as yours??would the chasis stand??

[@madbikerdesigns3600]

If you have a YPVS engine the same kit will fit on your cases. As for the chassis, im not sure. It may need bracing as its a big power increase over what it was originally designed for. You could also look into the Athena big bore route though

Awesome !!!! Is the engine reliable ?

[@madbikerdesigns3600]

Thanks. Yes its been very reliable.

Mad Biker Designs The hardest should be to find good carbs and good jetting

[@madbikerdesigns3600]

2218alex We have tried a few carbs and are now using Mikuni 38mm flatslides. Jetting is on the safe side but for our customers we can give them a good starting point if they go for the same set up.

Mad Biker Designs At 1.14 it seems the carb is on the Dark side ^^

2218alex Hahaha, she pulls like a train!
