Yup for the money the GP270 engine is a great engine....
the 30.5 cc with the 2mm stroke will give more torque on low end....
If I was to build a 30.5cc engine I would use a 1mm stroker crank....that would give some rpm's plus some torque...but not real crazy torque like the 2mm stroker crank....
If you like the GP270 the way you buy it then stick with it.........
The alum front brake blocks work...I could not find any so.. I used two 2 small screws as rebar and used epoxy putty to make a square bolck...it worked fine...later
it went to front cable brakes....I just dermaled off the epoxy putty....Slawhammer
do you mean the cy gp290 motor or the nzen g270rc motor
30.5 cc is a good motor ive built a couple, but to build a 30.5cc you need a +2 mm crank (30mm) and a gp290 head (28.5cc) if you use a + 1mm crank you get a 29.5 cc and a little more top end,
ill stick with the g270rc motor, but while im waiting to buy a new head and piston ill use the new g260rc zen motor that came with the fg mt also another fine motor.
