Glad it was received in one piece but sorry to hear about the rings.bc117 wrote:so i got my motor yesterdaynow i only have a few problems i have to adress and i should be good to go
i am missing the slide and cap to the carb and one of the rings was stuck in the piston even after a day sitting in carb cleaner and an hour in the ultra sonic cleaner plus a bake in the oven at 450 degrees, i ended up having to pry it out with a small pick breaking it into pieces so now i am on the look out for at least one standard bore ring for either an aero 80 or cr80
Bear do you know if the cr80 rings will fit in the aero piston and will +0.25 rings be made to fit, both the piston and bore are immaculate so i don't think i need a new piston or rebore
My race motor pistons only had one ring. Back in the day all 2 strokes pistons had 3 rings, no the standard is 2.bc117 wrote:so i got my motor yesterdaynow i only have a few problems i have to adress and i should be good to go

Back in the '70s and before every thing had 3 rings. In the 80's the change over to 2 rings was completed. But even back in the 70's single ring race pistons existed.eliteguy50 wrote:How far back is that?Bear45-70 wrote:My race motor pistons only had one ring.

Porting, induction system and exhaust system have more to do with revving high the the number of rings. More rings just increases drag which hurts house power production.spree-rider wrote:current day gopeds have only 1 ring so they can rev high.

One ring is sometimes used just for cheaper production costs.
