i used my brake bleeder to suck out the oil from in the crank area, as havent taken motor out of bike as yet but wanted to have a bit of a look at it.
Took off piston, the main bearing has zero up down movement which im very happy with, lets just hope the oil in their was preventative as storage or seeped in from oil lines - is there a best way to tell this ?
The oil had zero water in it and was identical to that from the oil reservoir
Here are some pics of the piston that came out of second bike.
i cant see any actual markings that its a Wiseco, im guessing due to the sticker on the tank that maybe they upgraded.
Its def not a stock suzuki piston as has no suzuki markings on inside (like my other orig on) but it does have TS185R on the inside of piston.
Piston appears in goodish nick, some blow by, not too much scoring, though it does have one mark where it appears to have maybe hit / scraped base of barrel at some point. The skirt has no cracks, although it does have a little flat spot on the four corners of the skirt, seems pretty uniform, not sure if from manufacturing or from being in bike ?
im a noob to pistons, but compared to my other orig one this one appears to have a slightly smaller diameter but the rings seem designed to "flare" out heaps more than the stock rings on other piston.
so some questions
what do ppl think this piston is? any specific wiseco markings ?
does it seem in ok condition
is it true the rings flare out further / better than orig piston / ring setup, whats the benefit if so ?
cheers
