I have just broken the foot lever off my Son's NTV centerstand. The reason is twofold. first is the fact that it is rotten with rust as there is a serious water trap in the foot lever. Second is the effort needed to assist with lifting the back wheel off the ground. When the bike is on the stand the back wheel is about 35mm off the ground. Getting it over the stand needs some serious downward force on the foot assist lever. Is that amount of clearance under the rear wheel normal? or is my rear suspension not extending properly? The rear shock is a secondhand item and whilst it works reasonably well there is almost no sag when dropping the bike forward off the centerstand. I plan on shortening the legs on the stand when I repair the assist lever. (the assist lever is much thinner material than the main tubes of the stand)

The stand is in pretty good shape apart from the missing foot assist lever. There is no wear in the pivot mechanism so I don't think there is anything to be achieved by obtaining another one. As you say they are pricey so I'm going to modify the existing one until it suits my bike. Any thoughts on the lack of sag of the rear suspension unit?

I knew nothing about SAG and suspension set up when I bought the bike. I only knew that I preferred a stiff set up from a handling point of view  this is why I followed the radial tyre pressure recommendations from Michelin, i.e. 36psi front and 42 rear and ignored the recommendations in the Haynes manual. I already had Hagon fork springs fitted with 15w fork oil. I then took the bike on the road on a Sunday morning, and set the rear suspension through trial and error (i.e. stopping and starting to readjust, up or down). I wanted a basically stiff setting but not so stiff that it effected steering adversely and of course, I wanted the bike to be stable at higher motorway speeds of around 90 -100mph..... So, I can’t really answer your question on SAG but: • Free SAG: free SAG is how much the bike sags under its own weight.
This is measured after you have set the static SAG. Too little free SAG
means the spring is too soft, and too much free SAG means that the
spring is too stiff. This seems contrary, but correct in practice. See
Approximate SAG Setting Charts: MX - Forks and Rear Shocks for more information.service.foxracingshox.com/powersports/Content/MX_suspension_tuning_guide.htm#sagbmAnd of course, there’s plenty more info on YouTube. www.youtube.com/watch?v=Xi95sLZJwnwGetting a replacement shock is not easy for these bikes. Hagon do one but again, it’s pricey. It might be a better idea to have the current shock reconditioned, if you think it needs it.... |
