Drive belt adjust on RYCA CS-1
09/01/12 at 12:00:59

Since the swing arm is angled down so much lower in the RYCA configuration, the stock belt tensioner tool doesn't work anymore.

With the RYCA configuration it would seem the belt would be pretty loose with no weight on the bike in order for the belt to be not overly tight when the shocks are fully compressed.

What is the best procedure for adjusting the belt on a RYCA CS-1?

The important part is to make sure the swingarm never overtightens the belt.

While doing the swingarm carving, I took off the shocks, and (using the motorcycle jack) lowered the bike to where the rear tire was just about to hit things. The swingarm on the RYCA is still not straight out at that point.

So, I need to get the minimum length of the RYCA supplied shocks to see how far they will let the swingarm move up.

It would seem the best (safest) way to adjust the belt would be to take off the shocks, lower the bike slowly until the distance between the upper and lower mounting points are the same as the distance for the compressed shocks. That is the point where the belt will be the tightest.

Adjust the belt fairly tight at that point. Any other position of the swingarm allowed by the shocks will make the belt looser.

Raise the bike back up and install the shocks.

What is the distance between the mounting holes on the RYCA CS-1 rear shocks and full compression and no compression? (max and min length)

I'm working on a more precise belt adjustment procedure, and I need this specification. This is a big deal for me because the Avon Speedmaster tire I use apparently has a larger diameter than was planned for the RYCA-modified swingarm. There is very little adjustment available between the point of the belt being too tight, and the tire rubbing on the swingarm.

This method scares me because of the way the swingarm is down so much further than stock. When the RYCA shocks are fully compressed the swingarm is still nowhere near level. This is why I need to know the compressed length of the RYCA shocks.

If the bike is in your garage, you can figure all this out. In fact, you can do better than just having numbers, you can have real world application data. Put a zip tie on the shocks & ride it & see how much the rod slipped into the tube. Odds are youll never bottom those shocks. Well,, If I was riding, it wouldnt happen, I weigh 160 & dont fly off of hills.

I just need to know how far the swingarm can move up with the RYCA shocks installed. Without fully compressing the shocks myself, I don't have that info available. I don't have a spring compressor that'll work on shocks.

Maybe I could take all the preload off, and find someone who hates the Wheat Belly concepts and have him put his 300 pounds on the bike. THAT might fully compress them.

What is it exactly youre trying to check for? Tire clearance? Or are you trying to get the belt adjusted?

I had the axle adjusted for the belt. I discovered it was too close to the swingarm,.. the tire rubbed. When I adjusted for tire clearance, I was afaid the belt would have been too tight when the shocks were compressed.

There is not much leeway, here, between making sure the tire does NOT rub at speed, and the belt being too tight when the suspension bottoms out.
