Inner Rotor Kit for Xtreme

[jrkapel]

Has anyone Installed a Inner Rotor Kit on 90cc motor and if so does it make a difference?

we just installed one on a xr50 and it made a huge difference in how it revs and power curve.

I have not seen an irk on a quad but I bought my son a pit bike for Xmas (ssr 90r) & it has a irk on it. That little bike really runs. Revs alot faster. After the Holiday rush I was thinking about trying to install one on his Can Am ds 90x

I found out it would work but I need to modify the case cover to make it look good.
