@Calum thanks for replying,about the cdi restriction,the past owner did derestrict the cdi and it worked fine untill the bike started having problems,also i could definitely feel the difference before the problems when i disconnected the earthed wire so im sure it's not that(i was curious what was the difference),i also checked the wire when it started to have this problem and it looks fine.
I will also add that i derestricted the exhaust about a month after i got the bike and the bike still didn't have any problems ,in fact it actually worked much smoother
About the electric start issue what should i do,i would know how to bypass the sidestand switch but not the clutch and neutral switch(i don't know where the neutral switch is)
