Add two batteries, and wire them in series so that the starter is getting 24 volts. Kiss your starting problems goodbye.:p

check your compression and your valves.

how much larger is that 190cc battery? what mod did you have to do to the batter holder?

i cut the back side of the battery box off and welded a small peace of angle so it dont slide back its well worth the work that starter spins like crazy i just got sick of slow cranking battery cost about 150 ytz10s you also have tomake a longer wire for the postive side and relocate the ground to the starter
