Default gearing question

this is a general question for someone that has fiddled around with ratios and could give me some advice seen as im fairly new to the gearing side of things.

i am running a sirio .27 in my savage and have a 14t vented clutch bell to a 52t spur gear. this wheelies on acceleration so much that it flips on full throttle

i presume this combination is giving me more pull away power??

is there a combination that will still give me the power to wheelie on pull away but also a crisp acceleration with a good top end??

if i was to add a 16t to a 48t i guess i would have even more top end and still good acceleration please help

The LRP is more of a torque motor and the Sirio's torque range is significantly higher in the RPM band.... That said the taller 18/49 is better carried by a torquier motor with less top-end RPMs...

With the Sirio I would go with a 16/52 first. If you find that you still have tons of bottom end and you'd trade a bit for top-end speed jump up to the 17t bell.

Not from a dead stop on pavement... maybe off road if you hit a bump under throttle...
