I am currently rebuilding my QT50 with a few performance upgrades and had a few questions, this is my first 2 stroke build so forgive my silly questions if they seem obvious.
mods:
- Malossi 70cc kit
- MLM clamp style intake
- VM18 carb
- malossi E12 air filter
- boyesen dual stage reeds
- MLM pipe
- premix (oil pump removed)
1) what plug should i be using? i was going to run the stock BP4HS but im guessing ill need a colder plug now.
2) what oil ratio should i run? ill be using amsoil saber, from what i have read 32:1 is the norm.
3) whats a good place to start with jets? i have read 30 idle and a 90 main for my setup is a good starting point.
4) Can i take 1mm of material off the stock QT50 head at the new piston diameter and run it like that or is there a better method? treats said that a new head will be coming out soon but im inpatient.
PS will be getting PW50 rear gears also.
Thanks.
