Bowman rings....Gone!

Great thanks. I'll give these guys a call tomorrow and see if they can help.

Just run the stock ones, they changed the material used a long time ago and they break in just like DA, ZDZ etc. They do have a slightly larger gap but they are doing well. Both my DLE120's are two years old and running same compression as my 111 with bowman rings.

There it is. The newer ones are just fine. No need to put different ones in.

Alright that's two votes for the stock ring's. I'll save some money and stick to the stock set. Still going to find out if that's a good source that chickenballs give me and report back with what I find out.

I just emailed the company and the smallest bore they make rings for is 2". The DLE 170 has a 2.05" bore. Other than that, most everything else is to small for them. I didn't bother asking about price when I found out this information.

Ask @Flyrcjoe talked to him at HOW, and he gave me someones contact for finding decent rings. I can't remember who it was, BUT he wrote it on top of cowl box we had in camp. @emtp275 look on that box tell us what it is.

What motor are you looking for rings for? I do stock ZDZ parts at http://zdzusa.com/.
I think you might have the wrong Joe. I have never been to HOW. I don't know of any other ring manufacturer.

Ok well that's no good. Back to the drawing board

I have to agree some with the new rings in DLE being better, I was a huge difference in the performance of my 55 when I did it but my DLE 61 the gap was smaller but the motor didn't seem to improve like the 55 did.

Edit.. I must fix what I said lol after looking back I did get an increase with the 61 but the 55 and my 30 were night and day

I can say that my 120 was greatly affected by the addition of the rings, mostly due to the reduction in ring gap, and the bowman rings seemed to make better contact with the cylinder wall compared to the stock rings. Although I have not measured the compression with a gauge I noticed out of the box the bowman rings had improved compression in the 120.

I also installed one in a 55 I used to have. I would say that the compression in that was also increased. Performance of that engine was better after the ring install.

THat ain't good news, but sounds like from reading this thread, the china guys are making a better ring.

What should be the tolerance for the gap
