Changing Forks Oil for my scooter Skygo Executive 250 ? By rock71 (Read 483 times)

  Hello Experts Scooters guys, greetings from Caracas,
       I'm having some problems with my front suspension, it goes to the bottom when brake the bike and when I'm in rough terrain badly, then I wonder if it will be enough are just get all the Chinese oil and put a good oil 15w as Motul Fork Oil
     My bike is similar to the Roketa MC-79-250, I would like to know your opinions if it is a good way to just remove the hex screw from below and above the forks, without removing the entire front forks could work for me.

this are the photos of the hex screws.

Thank you for you help and comments!

They should simply screw out with the proper size allen head wrench. This may help:

Remove the front wheel,, fender ,,brake calipers,,,loosen the top hex cap only,,,then remove the fork ,,when the fork leg is off the bike remove the top cap,,,( be careful the cap is under load from the springs) the original oil is probably 5w,,, I'd go with 10 w myself but 15 will probably ok,,,turn the fork over in a bucket and let it drain,,,pump it up and down a few times to make sure you get all the oil out

I've had remarkable transformations in damping performance with just a quality fork oil change,,you can do minor spring preload changes by cutting a short section of schedule 40 irrigation pipe and put it on top of the spring in the fork,,,we're talking 1 inch or so,,put a large flat washer on top of the spring then the spacer of pipe on top and you're good to go,,,oh as a side note you can put a few more ounces of oil than the factory calls for,,,this reduces the air column and makes the spring rate stiffer,,,they (the fork manufacturer) factor in the spring rate of the air being compressed inside the fork,,,so with a little juggling you can get great results for not much dough
