Static SAG 300SEF-R 2019 factory
« on: June 25, 2020, 03:54:47 PM »
Hello all,
I have just purchase a used 300SEF-r 2019 factory. I measured the static SAG and it's around 52mm. The manual says 30mm.

So I think i have to have more compression on the shock. I have tried to do this without having to remove the shock but with no sucess. I can't get the first "collar" do move so that i can adjust the compression. Is it mandatory to remove the shock?

Any thoughts or help?

Regards
Luis Cabral

Ok try this but not always possible
Bike on stand rear wheel off floor
Spay lock rings with WD 40 type spray leave a few min to soak in.
I use a aluminium rod on top ring to nock the ring loose as it will not damage ring
You can gain better access by rocking the shock a little out the way
If it loosens nock the lower spring anti clockwise to preload more
I mark the ring with paint pen to see one turn
1 turn about 3/4 mm sag change
If you remove tank you can get some access to the rings I have a shock spanner Iíve Adapted
Fit that way.
If thatís not happening remove the shock and free off then keep it sprayed up after washing so the above can be done.
Some people run a long wheel base and forget it has a effect of making the rear softer
You can try and turn chain adjusters round to shorten swingarm  for a test if you donít suffer stability problems
I normally drop the bike and push down on the seat a few times before checking
Also measure a few times and average out as they donít always settle exactly the same every time
Maybe a over explanation but lockdown boredom set in

You probably need a stiffer spring.
52mm is probably too much
To reduce by pre-load on the spring.
Clockwise increases pre-load.

The mans right clockwise sorry
Also a/arm length will be determined by chain length and sprocket size
Thought Iíd better put that right before someone else
