    Don't they make a hone type device that hooks up to a drill that just deglazes and wont harm the coating on cylinders? Im just thinking that something should be done when installing a new piston and ring to aid the ring in a good seat??? Am i totally off coarse on this?

    Depends on the engine. Cast iron sleeve two stroke can be honed. Newer aluminum cylinder with plated liner - no hone.

    If you had aluminum transfer, you would have acid treated then light sanded. that would have been enough. If the cylinder is in good shape, nothing is needed really, just install and run it.

    Acid

    So you only use a qtip to apply or do you soak a rag? Im not sure what I even have aluminum or cast. Its off of partner 500 and pretty sure they are factory.

    Q tip to apply the acid. I warmed the cylinders with a heat gun and it will work faster.

    q tip, you don't need much. really, small amounts, then plenty of rinsing. it will eat your eyes and make nearby stuff rust. Only get it on the aluminum transfer that is over the plating, no place else. it will bubble and smoke and stink while it is cooking/dissolving. Rinse really good, then light sanding. Don't go through the plating. Eventually you will see if the cylinder is worth reusing or not.

    I did one, after getting the transfer off, had two places with lost plating..no good.

    i really need to take some pics of the cylinders and post on here because in all honesty I didnt see alot or any aluminum transfer. Maybe these cyl's are cast and are just wore thats giving me low compression

    chrome plated aluminum

    Model Profile: 500

    edit, who knows might just need very moderate cleaning and new rings. Ya go ahead post up some clear closeup pics of cylinder and piston, let the smart guys look at them.

    They do make/offer hones for nickasil cylinders. I have the lisle gear driven adjustable bones. These hones are so accurate I can put in coarse stones for castiron and bore with them. Then when there close to the bore size I need I switch to the fine grit stones and finish it with the fine cross hatch for chrome rings,

    Never hone a nikasil cylinder. Read Whitedoggone’s post.
