Tuning Gear Help

[gza710]

I'm trying to resurrect my SA50 engine for daily use. Currently, I have on it:

70 (something?) cc bore kit
Arrow Pipe
28 Kehin Carb
stock gears
mod pulley
mod clutch spring
All on dio zx wheels (30/30?)

I can feel the gears holding it back big time and never got to changing them until now. I'm pretty much a noob on this so I was wondering what gear ratio do you recommend for this set up. I'm about 180lbs and need to go up a pretty steep (20% incline?) hill to and from work. I also need to keep up with traffic so looking at about 50 to 60 mph top end. I've read a lot about gears and gear ratios on this site but still need inputs based on experiences.

Any help would be appreciated.

Thanks

I enjoy 8.4
240lb rider 60+ anytime is nice with a very simple setup

+1 for 8.4:1

Not sure. I'm burying the needle. So at least 45 - 50. It just winds the gear up a lot. And the low end is too much.

I just found out that my primary gears are 13x34. 87 gearing in my 94 motor. Is that good or bad? Which secondary gears do I get?

OK got all the gearing help from moped connection. come to find out the previous owners of the motor swapped my dios motor with 87 gears. so i ended up swapping my entire trans to dd50 set up. now im at 7.44 ratios. thanks for all the help.
