Do you have a scale? Weight the ones you have in grams, then measure the rollers in metric. This will give a good idea of where you are starting at. Then decide what you want as results.

Heavier higher top end save a little bit more gas. Lighter, takes off faster uses a bit more gas. IMO

Ever gram you go up or down changes the RPM's by 500 RPM's Sliders are nice if you can keep them in the variator not getting shifted as mine kept doing.

You can go one gram up from the weights you are on and have little affect on total performance but might have a slightly higher top end.

Also you can get a tuning kit from Prima on eBAY. They are very useful.

All this is dependent on the carb being tuned correctly.

Have fun

Do one change and check results.
