I have a XingYue XY150. is there a way to adjust the front forks? they seem way to soft to me, and will all but bottom out when I just sit on the scooter. Is there a way to adjust them so they are stiffer?

The forks are non-adjustable. But as a advanced mechanical thing, one can put in some spacers to stiffen the springs up more. But spacers also reduce the travel (how much the forks move up and down) too.
if you had access to a lot of motorcycle forks, you might be able to find a set of stiffer springs you could swap out for it. But that isn't normally something most of us have handy.

My forks on my previous GY6 model Lifan were way too stiff and even stuck in a compressed position when I would come to a hard stop. I then had to pull up on the handle bars to expand the forks. I disassembled them and replaced the real thick, crappy fork oil with 7 weight fork oil. Softened them up quit a bit. Possible you may not have sufficient fork oil in yours to help dampen the bumps, or maybe the oil is just crappy. You could try replacing with a heavier oil. Don't know what to recommend for a weight. I have seen some posts going with a 10 weight oil. As I said, I used 7 weight and thought it made for a good ride.
I will look to see if I still have the pictures that I took during my disassembly and reassembly of the forks...but that was a few years ago so don't count on it. Maybe someone else on the forum has some pictorial instructions.

Earlwb mentions springs on the front, but my Diamo doesn't have springs, just the plain fork/shock absorber. My right front fork has a bad seal, so the oil drains right out, and my dealer can't/won't fix it properly. So when I hit a bump, the front tire has rubbed a hole in the underside of the plastic fender from all the bottoming out. It costs over $100 for a new fork, so I'm trying to figure out a cheaper solution . . .

scootwes, i'm pretty sure there will be springs inside of the front shocks absorbers. there will also be fluid. the stiffness of the springs will dictate the overall travel as well as how stiff the ride is, the fluid viscosity will dictate how quickly they can compress and expand (thicker is slower).
at least, from what i've read that is more or less how it works.
as was mentioned, access to replacement springs or different springs may not be readily available so the only other option is to put a heavier weight oil in there.
as far as rubbing, that's not so good. when i ride two up with my wife on the back the rear suspension can compress enough on bumps that the mud guard contacts the fuel tank, causing the tire to rub on the mud guard. it's on my high-priority list of things to correct on the scoot, as that kind of chronic rubbing can lead to tire blowouts.

Hey, dumb question, but how much do you weigh? I'm 175, and I can't bottom out my forks even if I'm laying on the bars... and when you're sitting on the scoot, most of your weight is on the rear tire anyway...

If your dealer can't or won't help you, would a local motorcycle dealer assist you? They work with forks and fork oil and if they will, I am sure they can be of assistance with the oil to use if nothing else.
Good luck

Is there a way to adjust them so they are stiffer? Mine was the same way when I got it and bobpt gives good advice; replace the fork oil. Mine looked like river silt and took me forever to get it all cleaned out. Worked like a charm afterwards though.

les, did you take any pictures during R&R? What was most difficult part?

You know, I'm actually a professional photographer so the last thing I'm thinking about when working on my scoot is a camera; I'm generally too busy cussing and throwing stuff to take photos. I probably should make it a point to document this sort of stuff, though. The caps on the fork tubes were pretty tight but, for me, cleaning all the sludge out was, by far, the most time-consuming part. Just pull the nose off of your scoot and take a peek, its pretty straight forward.

I just did a rebuild on my forks the other day, and after cleaning out the sludge, a fresh set oil seals and some automatic transmission fluid (filled to two inches from the top when fully compressed) the bike actually handled better than when I got it seven months ago.

All the talks of sludge found in the front forks makes me wonder what is in the rear shocks..,

My front end seems to feel every imperfection in the roadway. Is this something that would be helped with new fluid? What weight?
