Looking for advice to begin getting one of my Raiders to run as powerfully as the other.
The only difference in them is the tire size and it is not a gross difference - of course some acceleration difference can be accounted for by that but the difference I am seeing is GROSS.

I thought of the following - and I am starting these changes:
New Air Filter
New Spark Plugs
New Fuel filter
Check timing

What other things should I check or change or upgrade to make this run as powerfully as my other exact year Raider?

thanks!!
