Full throttle of the line it goes to 6,000 then hangs most time especially on hills and upward slopes

I need help what to do , do i adjust the clutch to engage at 7000 rpm or 7500 or around there as thats were it builds power and has enough power to propel itself of the line because nownit enages about 6,000 rpm which is 2bhp which ithink is no were near enough to get the bike going so it can build up to its peak 9,000 /1050 rpm ? Please if someone can help id be greatful

 

Junk all that off and fit a 70cc barrel kit, std upjetted carb/std pipe. Lovely !

 

It has standard crank and bearings tho ? Tho crank has no play in it tho and what do you have on your typhoon ?

 

The std will be ok with a 70cc barrel. Mine is a std 125, beryl is 15 y/o I've owned her from new, over 40,000 miles and still on the std crank. Only mods are 12" wheels.
