MOPED ARMY

you should have asked mr you know who about fork set ups. i think he just recomends using more or less oil.

nice! maxi length hydraulics would be awesome. i've got some mkII forks i was going to sell to get maxi ebrs, but i'd definitely rock the mkII's if i could lower them. let's keep this updated. anyone know this john dude?

When I rebuild my magnum forks I switched the bottom springs. It definitely lowered them. I didn't put more oil in because some of the seals where missing but this winter I am going to fix that.

The forks compress really well but they uncompress so fast and hard. You don't really notice this as long as your front wheel stays on the ground. The only time it bothers me is if I try to do something like do a little wheelie or manual off of a curb. When the front wheel comes off the ground it feels like the forks are bottoming out hard but in the opposite direction. It's pretty jarring to your hands. I am hoping that oil will help smooth this out.

I am not sure if this is explained well. If anyone is confused let me know.

I would definitely recommend switching those springs. Do keep in mind that when you do this that the studs that stick out the bottom of the fork will need to be cut down a little or they will get in the way of bolting your wheel on.

I don't know if I would Cut the main spring. If you did it would definitely sit lower to the ground with weight on it but when you picked the front end up I think the forks would just slid back to normal length.

Honestly I haven't had those forks apart for a while now so I don't remember every detail. I just mentioned things that I did remember. Good luck guys.

i was so poor this year i ran my minarelli hydraulics all year on spare brake fluid. haha.

Most professional motorcycle road race teams spend 80 percent of their time trying to get the suspension dialed in. Mainly the front. ( they have PLENTY of power) That should tell you a lot. I wish I had a set of the forks you are talking about, because I'll bet I could figure out how to make them work good. Rider weight is BIG factor, however, I haven't seen different weight springs for Mopeds. Since you guys didn't put a lot of pix in this thread, there wasn't enough info to SEE what could be done. More things can be done to forks than most people realize.

unfortunately I didn't replace my seals when I "rebuilt" them. I did add a sweet round, aluminum spacer to stiffen up the springs though.

The spacer is so awesome, way stiffer, but not too much. I think my springs were worn and soft, so this helped make it feel more like a new pair.

I just found a set of magnum hydro forks. They should be here in a week or so. I'll be tearing them apart to see what makes them tick. I doubt that the valving will facilitate a way to adjust rebound damping, never the less I will try. Usually some damping orifices are brazed shut, with the final adjustment by using different weight fork oils does the trick. I have done many for setting up road racing bikes. Much can be learned about setting up our mopeds by seeing what our bigger bros do. I have worked with Dave Moss on several occasions. He's known by everyone on road race circuits, mainly in the west, but regularly works with pro teams at Daytona every year. Check out his suspension tuning videos on youtube. I'll be posting my findings when I'm done.
