Stu Pidasole's Build

My question was based on the fact that under compression the bottom length of chain will move closer to the swingarm and under rebound the top length of chain will move closer to the swingarm. This is fairly easy to check. However, if Larry is using the exact same setup including swingarm and sprockets and there is no contact between chain and swingarm you should be ok. If not, you'll find out when you hit the first bump. :laugh:

all that also depends on shock travel setting, and or sag. i forgot how many miles Larry has on his bike. in any case the rear sprocket i baught was $20. once it wears i will put a steel/titanium one on the bike. by then ill know for a fact if i need to bump up rear sprocket diameter.

Sag has nothing to do with shock travel. Travel is built into the shock and by the stopper on the base of the shaft. But you have flat roads so no worries.

so if my chain rides against the chain guard on the top of the swing arm it wont work?

What kidkawie means is that total shock travel is set by the manufacturer and is not readily changed, if at all. That said, your sag setting will take up some of the available travel. Remember, travel is measured at the wheel, not at the shock. To check your chain to swingarm clearance, remove the shock spring then reassemble the rear suspension. This will allow you to move the swingarm throughout its range and see what hits where

Thanks Adam.

Chain looks to be running pretty close to the swingarm. Have you checked to see if it touches anywhere through the full up and down swing of the arm? If so you may consider larger sprockets. Ed

there is a 3/4" gap between the swingarm and the chain. also the bike has no weight in it. there will be a chain guard installed before its all said and done. Larry C. has the same sprockets i do. I dont hear him complaining. Go Larry! The nice thing is he has done most of the guess work. Once i got past the frame mods, it should run a lil smoother.

There's a plastic chain guide that goes on the arm. There's no issue with the chain being to close to anything that I see in the pictures

If the guide didn't come on the arm, buy one. You want it on there for sure.

Be sure to order a chain GUIDE rather than GUARD. When you said you were going to install a chain guard I didn't see how that was related to the chain touching the frame. Ed

Chain GUARD:

Im just a lost cause ain't I ed? Lol. I said it wrong....if you though I thought a chain guard is what I needed to keep my chain off my swing arm....well...:laugh:
