Hey Eric, my son is on an '02 CR80, thanks for the suspension info. He is about 100 lbs, so I will experiment with the Sag. Did I see that 3" is the correct sag setting?
Also, with the chain, I seem to have problems getting it just right. We loosened it up, then went riding and after a couple of trails it was back to tight. I know it is worn out and I have a Renthal R1(?) on order, but is that typical of a worn out chain to tighten after a short ride?
Once we get the new chain and sprockets on I hope after the 1st day I do not have to adjust it anymore. With the cheap chains it seemed like adjustment was an every ride task.
Also, the bike came with an FMF Fatty and Turbine Core 2 with Spark Arrestor. I am running it with stock jetting and needle, but get a bit of spooge with Honda Synthetic oil at 32:1. I am considering changing the jetting a touch, seems that 122/52 seems to a common set up, also it was what FMF recomended with the fatty.
Finally, I ordered the spacer ring and moose torque spacer, and a taller rear sprocket. hoping to bring some of that power down to the low/mid range. Would do a port job but do not want to wait 3 weeks. I will post after the changes and let you all know how it goes,
Any other advice, please share,
Mike
