Hi everyone!
Please tell me a good balance factor for 1 cylinder engine without balance shaft. I read somewhere that the balance factor of vertical engine (piston moves along vertical axis) is different from balance factor of horizontal engine.

I have tried a balance factor 71% for my 1 cylinder horizontal engine and it runs worse than the stock crankshaft.

Please give me some advises.

I have an ideal that:
I measure the balance factor of the stock engine with stock crankshaft and stock piston, then when I use bigger piston I will modify the crankshaft to keep the same balance factor. Is it a possible, had anybody does this and have a good result ?

sorry, my English is not good ^^.

You shouldn't remove anything...most engines have an appropriate counterweight ...you'll screw it up
