Victoria! Zeke's CB175 Build

probably both sides the cam is feeding pulsing loads into the chain
it is not like the dynamic of the final drive chain
the cam lobes are constantly requiring energy then returning it

did you quench the gasket in cold water while it was still red hot

Lani said to use room temp but yes we took it through blue green molten orange. Then we quenched it flat into the water! Gaskets are like gumby. :)

We checked our ring gap clearance:
.007" compression
.009" scraper
.008" oil

The 88cc honda is a 52mm
The 110 is 60 mm

better safe than sorry it does not affect compression to have a bit more

i agree Tbolt says it is the rule and then they break the rule

I've found it's easier to use stove hotplate to anneal small copper gaskets.
Heat to dull red and dunk in kitchen sink full of water. Have to make sure everything is cleaned up before wife gets home though ;)
If your using new rings in a fresh bore I wouldn't worry about being 0.0005" undersize, the initial bedding in will allow end gap to open up

what do you think about David Vizard's plateau polishing before assembly with the maroon scott brite and gunk? Swirling in a vertical motion?

If it gives a good plateau finish use it.
If cylinders have already been finished with a 400 grit Flex-hone, not sure if it will do anything other than make sure all the oil and micro crud is removed

our cylinders were finished to 280 grit so as for final assembly we could do what I read about David Vizard using a maroon scotchbrite 360-400 grit to knock down the peaks before assembly using a spiral vertical motion until the cylinders were smooth. He washed the cylinders first and then sprayed them with Gunk and then used the pad and sprayed down with Gunk again then washed the cylinders. Kop also gave me similar advice before I read about ViZard's secret to more power. Of course this is a hot topic on other boards and some like to bash Vizard. However all of his advice has worked for us.
