Now that’s bringing new life into some beat valves!

I watched the blue twin cam videos now I’m watching this, and I’m seeing the same shop at the same time, but from a different camera and setting. Reminds me of that movie “vantage point”, which is the only movie I ever walked out of because it was so bad. This is much better viewing.

same camera, just different places. i video what i want and am always doing something. the customer was working on his bike and i was doing a different job. tatro

Got a question Tatro. Have a 74 iron head wht type of wires are best for spark plugs. Thanks for your time. Do have electronic ignition. But I think a factory (or similar coil).

[@TatroMachine]

all points motors use copper core wires and all electronic ones use suppression wires. any good name brand wires should be good. watch out on those cheap import colored wires. tatro

@@TatroMachine thanks for the reply appreciate it

If I didn’t have an external hone like yours could I use emery or micro paper on the lathe?

[@TatroMachine]

not really. that will make is smoother but not straighter and rounder. now if you had two v-blocks and a wide clamp you might have half a chance of making things better. tatro

[@izzynutz2000]

That one intake valve looked a little wibbly wobbly while you had it in the lathe was that just because you didn't have it exactly in the chuck? Or a bent valve stem.. I think the second one you did

[@TatroMachine]

the notches in the lathe jaws are not all made the same so things move around some. tatro

I’m currently rebuilding a 81 sportster, going to be putting wiseco pistons in it. I noticed you use Hastings pistons rings often. Do you suggest using them or are the rings what come with the new pistons good enough. Also putting in those 10:1 pistons, do I need to change the cam lift to compensate for the increased compression???

[@gv87au]

Also is it possible to have the 10:1 pistons brought back down to standard compression, ie machine the dome on pistons or thicker head gasket

[@TatroMachine]

use the rings that come with the pistons. they work good with each other. you better have good gas. tatro

[@TatroMachine]

why would you do that. just get the parts that work for your application. tatro

[@gv87au]

Tatro Machine I want to use wiseco pistons as I k is the quality of them. The pistons I have are junk and I have read mixed review on the pistons you can buy from certain companies online. I though of using the wiseco but lowering the compression back to stock

[@Scalihoo]

informative 👍

[@edwardjohnson5331]

I'm all about saving some coins , but why not new valves , springs , keeper, and such ?

[@TatroMachine]

because that is what the customer wants to do and the parts are still good. only a dumbass changes everything all the time. tatro
