Gearing for DR180?

Hi Friends,

This is my first post so I hope you can help.

I have a standard PX125 electric start motor - came with a DR180/177 kit which looks in good condition.

Question: I will remove the autolube and fit a PX200 carb plus Sito Plus exhaust I have. Can I use the standard crank and gears as i will not be riding for long distance full throttle? Or will this rev too high?

Should I fit a race crank? If I need to make the gearing taller which clutch cog and primary drive gear can I use?

I don't have a big money to spend so any ideas?

Thank you!
