Bowman ring question...yes another question...
 

Many times I have heard this persons name mentioned with QUALITY ring replacement. I don't know that I have heard it explained as to what he is doing that is better than stock? Is it closer tolerance? Better steel? machined somehow different ? I have been very curious about this for awhile, and I guess asking is the way to find out. I am assuming he sends you a ring..you don't send him the motor to be fitted to the new ring ...
Thanks

Send him the engine. He will make the required ring, install it, and return the engine to you all done. All for a very reasonable price. Doesn't matter if your engine is obsolete or not. Turn around time was quite acceptable. Piston rings aren't usually made from steel, rather from a high grade of cast iron called mehanite. What more could you ask?

If ya see my post about the 22cc echo twin you see i got new rings from frank.Instaed of me trying to go through echo i sent him the cylinders and he fitted the rings to my cylinders for a custom fit.It would be like buying a new set of rings and putting them in a used cylinder.They wont fit right.Thats why when you buy parts for good engines you buy a repower kit wich includes a jug,rings,piston,wrist pin,circlips,somtimes a new wrist pin bearing.With franks rings i was able to get a custom fit ring without all the extras at a very reasonable price of like $7-9.oo a piece.If echo even had the rings in stock or at all.The other rings i have purchased where much closer in the end ring gap.Meaning when you put the ring in cylinder you only have .001-.003.Some you can see the gap with your eyes.Maybe 5-7 thousandths.He will also pin your piston and make a ring if ya want him to.This is the ultimate seal.And this mod will raise your compression alone.

It simply runs better with a Bowman Ring.
