I read a post earlier but couldn't find it again. It was on how someone had put Bitubos on there LX150 and it was riding hard, So my question is where (on the big screw) should my adjusting plate be if I have Bitubos on my LX150? Does anyone know the best adjustment for riding around mostly in the city on pretty bumpy roads with Bitubo shocks on an LX150?

Here ya go. Gary and I went through adjusting mine a couple of years ago. Glad someone else could benefit from his knowledge.

Adjusting Bitubo shock?

You will really enjoy the improved ride.

Thanks again, Gary!
Steve

[edit] Ha! I just realized after posting that what my current avatar is.

SMORRIS I am not sure I know what to do with this.

The shock has a range of travel, which should be specified by Bitubo. For explanatory purposes, let's say it's 3".
To set the sag, you'll need to measure the length of the front suspension when it's fully extended and unladen (not under any load). Then measure the front suspension when you're sitting on the scooter. That's the laden length (under the static load of the scooter plus rider). It should be 1" to 1 1/2" shorter than the unladen measurement. You can adjust the shock's laden length, with the spring preload ring. That's the ring that you've labeled "compression adjustment". The spring preload doesn't change the characteristics of the shock. It only adjusts where the shock sits, within its range of travel. It's a constant-rate spring. Let's say the spring rate is 60 LBS per inch. Even if the spring preload compresses the spring one inch, the next inch of travel is still at the same rate of 60 LBS per inch. It also expands at a rate of 60 LBS per inch, keeping the scooter's attitude level in potholes.

No problem, let's do it another way.

External inline image provided by member with no explanatory text

In this photo, the gap between the bottom compression adjustment nut and the top of the red part of the shock body is approximately 15mm on my scoot after adjusting it to Gary's recommendations. That should make a good starting point for yours. If it is a little too firm, screw the nut closer to the shock body, too soft, further away (compressing the spring more.)

Now, open (turn CCW) the rebound adjuster valve all the way. Feel the little clicks as you open it? Once it is all the way open, close it 2 clicks. That's it. If it is a little bouncy for you, try one more click. I haven't changed mine since March '06, so Gary's suggestions were spot on for me.

Give those settings a try and see how you like them. You can always adjust a little to suit your riding style.

Good luck,
Steve

Ok not to sound dumb but by all the way open you mean turn it all the way to the left, right? (on the rebound damper)

ooh and one more question: What do you have your compression adjustment set to on your back shock?

Correct, all the way open (CCW or counter clockwise above) then two clicks closed.

I don't have the rear shock. There is some discussion somewhere as to whether the Malossi rear is an improvement on the stock shock or not.
