A lower rate spring in the RR will tighten it up, at least on dirt. I assume the same would carry over to asphalt

my cross weight was 47.9% when we took it to the track. dont remember the wheel base other then it was legal with a go/nogo bar. havnt had a chance to scale it again since race night. i have since noticed that the rr tire sticks out beyound the rf by an 1-1 1/4 so il be needing to move the rf out, im 6 in between frame and drum on lr.

If your loose in your cross is to low normally 49% is a good area for cross. I'd raise that up and try it out.
