Shock upgrade question By cvk81 (Read 946 times)

A couple weeks ago I bought a 2006 JM Star 150 scooter with only 775 chino-miles on it. Since then I have changed all the fluids except the brake fluid. This morning I rebuilt my front forks according to the thread linked below.
scooterdoc.proboards.com/index.cgi?board=techtips&action=display&thread=2845
This seems to be a pretty significant improvement, I might use heavier oil next time. I think adding about 1" of preload to the springs did more good then the better oil.
Only problem is, stiffening up the front now makes the rear shock unbearable. I am either getting every bump shot up my back or am bouncing uncontrollably.
I have seen upgrade shocks for around $250, but I only have about $400 in the scooter. Doesn't make sense to spend that much on a shock. Any more affordable upgrades out there?
Thanks for the great site, I have already learned a lot here.

I bought a pair for my GY6 150cc on clearance for $22 each, basicly the same as yours from here www.motopartsmax.com/index.php/main_page/product_info/products_id/11208/tID/3/cPath/251_394

They are a tiny bit longer and much wider, stock is 41mm wide, for a better ride. here is a picture:

Thanks. Looks like they offer an adjustable one for not much more. I will do some measuring and look into those. Forgot to mention, I only have a single shock.

I need two for my chunky azz..lol

I am doing the front shock mod tomorrow with 40 weight oil cause you said you wish you went with a thicker oil.

I used good quality 15w motorcycle fork oil. I weight 175 pounds.

Thanks for the post, I have been looking for months for something like this. I used to think the front end settled because of my weight when I started riding these bikes but now that I have finally dropped to 170Lb., from 235, , I think its just another instance of build it cheap, capture market share and sell better ones as the time goes by. Even at 170 LB. there is a road here that has no chuck holes, just bad surface that jars both my bike and old truck,
( New shocks about 3000 miles ago).
