Thanks for the reminder to look...

I have two used D-47's. One has stripped gears and the other I should keep in case I strip another of the servo's in the mini-blaster. It looks like George has this one taken care of.

The chain is at its tightest position when the swing arm is level which creates the farthest distance from the front and back sprocket. So if the bike has the swing arm facing slightly down with no passenger (uncompressed suspension), the manufacturer will specify more slack to compensate for when the suspension is compressed with a rider. You're adjusting for the tightest point not the point with no rider on board.

Sit on the bike or have someone sit on the bike to compress the suspension, and you'll probably find the chain has been way over-tightened to the point of stopping travel through the center-point with a light rider (swing arm level).

Adjust as the manufacturer says with the bike unweighted. You need more slack or you'll wear out the bearings, chain, prevent full suspension travel, and induce more rolling resistance.
Well explained Lee.

Thanks.

Charlie: What Skookum update? Wish there were 48hours a day.

Yep, to tight. Like I said, when you're first learning how to adjust a chain, everyone sets them to tight (I ate up several sprockets and chains learning )

I can swing by and give a better tutorial, it's hard to explain it on the phone, let me know when it's convenient.

Vu, I talked with my buddy that's going to MMI. Unfortunately, he's not in the Honda class, but he seems to think that most of the sport bikes from the big four are using a similar tensioning procedure right now, though he did state that it's always best to go with the procedure in the Factory Maintenance manual.

He said all the sport bikes that he and his dad have owned specify tensioning the cain with the bike level, NOT on the kickstand, and unloaded, to whatever the manual states.

I'm glad to hear I'm not the only one that killed a chain or two, and a set of sprockets learning the proper procedure.

With my old bike, the best investment I ever made (Aside from good riding gear) was the factory Honda maintenance manual. It had the specs for every single part of the bike, along with exploded parts diagrams, AND full pictures explaining how to service each part.

The next best thing I found for adjusting a chain... an old wooden yard stick of all things. Use it as a straight edge for measuring the deflection.

oh, that's right.... I thought a huge race riot/gun battle had started due to the immigration law. Now I feel stupid for hiding in my bathtub with a mattress over me.

Very cool that you got to see some of the Lost locations.

Hey question for those of you who fly in the heat. I took my EPP Yak and flew it the other day and apparently due to the heat I totally melted the ESC. I'm guessing that flying electric power can be a problem when it's hot like that outside? I probably was also using a slightly undersized ESC but still, totally melt it... WOW

Is there any cutoff point you guys generally use, such as not flying above 105 for ESC and Battery life sake?

In general, I try to prop down a little when it's hot. That's with an OVERSIZED ESC. I'm not competing, so I don't see any reason to run stuff on the hairy edge of destruction.
