Skyhawk 90 engine break-in?

I read the manual and it's weak. Just the basic do's/don'ts.

Is there any checking/retorquing of the head bolts during break-in on these puppies? If so, anyone know when and what the torque spec is?

TIA, and have a very, merry Christmas.

I would run the bike thru several heat cycles allowing the engine to completely cool between, before using wide open throttle. Give the bike a complete once over to check for any lose bolts. The head bolts should be tightend to 9.6 ftlbs.

Before you go on a ride, add some loctite to the rear axle nut and add some vibration protection to the battery.

After a few rides, check that head torque, adjust the chain. Beyond that, you should be ok

Uh-oh, already rode it. But it was Xmas and there was a foot of snow... [img]images/graemlins/grin.gif[/img]

Got the battery already. Wow, if just wobbles around in there. I used bubble wrap and stuffed it in there.

Okay, rear axle nut. You talking on the side of the drum brake? There is a double nut, I guess to lock them from moving. Remove both and Loc-tite? Red or blue Loc-tite? Do you know the torque setting for them? Thanks for the help.

Torque the head to 9.6 ft.lbs like the other gentleman said?
