The bike has been on hold for 2 weeks due to funky engine noises when hot and erratic power drops.
I am guessing either :
- head gasket (there is an oil leak) + chain tensionner guide
- shot clutch (was reportedly worn but stopped slipping as soon as I changed the oil) and crap in carb and tank
My only issue is I have no room to open up the engine.
Anyway, there is opportunities even in drawbacks so the plan is to ugrade the engine as far as FE is concerned
I am thinking :
polished combustion chamber
polished exhaust ports
higher CR (from 8,9 to 10 maybe)
flowed carb (if needed)
Keep in mind the GN is air cooled with no oil cooler.
Any advice on the spec ?
