I have been doing some reading, yes I know dangerous, and see the secondary spring can be tightened for heavier loads/ bigger tire. How is this done on a 22 Xrs rr? Will it help when I put a larger heavier tire? Any advice would be great. TIA

you need to advance the torsion one setting tighter, it will give you 50-100 rpms or so maybe more.

some models do not come with torsion spring ( no holes in the helix)
these compression spring models will need new/different spring
there are many videos on serving the QRS clutch
all qrs work the same, but there are some big differences
what I recommend is using a fish scale on the stock clutch
this will be like 15lbs, yours will probably be different
and then adjust the spring ( move to a different hole in helix)
and test again untill you get a little higher average like 18
all you need is vise grips and a fish scale to test
holding the clutch is the hard part...
doing it on a car with the cover is tough
about the only way is to remove the primary
going crazy and rotating the helix another 30 degrees
will give you a clutch that will not shift into high
cant use a scale then...
testing your new spring or setting is the answer
your looking for fast back/down shifting (no coasting)
and still shift into highest gear to achieve max speed
a new spring and a used spring are not the same
they get weaker as they age/use

Can you provide some pics or examples of how the test this?

Do you know offhand what my 2022 Xrs rr would have for holes, or just compression spring? I have never messed with these clutches before. I would be willing to buy a new spring and all tools if needed, but would like to know what I am getting into before I jump in with both feet.

Just pull your cover off and have a look. Have you ever had your cover off or changed a belt yet?

yours should have the adjustable helix with the torsion style spring from the factory.

Had cover off and installed carbon fiber protector in case belt blows. Just never did any clutch work before. I don’t want to mess anything up with a rookie mistake.
