Have any total seal piston rings in their Commando engines ?
Will I get more HP with these rings ?
I have a 1974 850 cc Commando , just bores out to +10
Where can I buy total seal rings ?

They're for Harley Davidson V2 engines so should be readily available.? My engine was rebuilt with them. Although I haven't fired it up, I've heard that it's a bit harder to kick. Probably good to pair them up with Jim's breather. He could probably supply the rings also.? Here's a bit from the brochure that came with them...

Hi Michael.
Fitted TotalSeal 0.020" oversize to my 750.
You keep the air:fuel mixture and burnt gases above the rings so you get all the horsepower you are entitled to.
No downside noted except to use correctly hardened pawls that come in Norton bags. :D
See link below for correct part no. then search 'Where to buy' (Denmark is not listed) so:
Austria - Matzinger Performance GmbH, Huegelgasse 16, Bad Voeslau, 2540, 43-2252-790-232
UK - PERFORMANCE UNLIMITED, 3 CHESSINGHAM PARK, NORTH YORKSHIRE, Y0195SE 1-904-489-332
You may struggle to find 0.010" oversized.

I have them along with JS pistons etc and am very happy. They just seem such a logically correct thing to do.

However, Jim Comstock posted a while ago that he saw little or no effect on the Dyno.

So, probably worth doing whilst the motor is down IF you want to, but not particularly vital.

Hi Fast Eddie.
I don't think comparing sets of pristine rings will show a difference on the dyno.
Add in wear and 'normal' ring gaps will increase with a corresponding blow-by gas increase and loss of compression.
All other things remaining equal, a dyno comparison after x,000's of km would be more use.
I have chosen TotalSeal rings to keep sealing for the long term (i.e. measured in years perhaps decades :D ). Hope this helps with your choice, Michael.

I concour !
 
Instead of wondering if the set of rings from Total seal are as good as what you normally run, you can just send them your #2 ring and have them do the process to that ring. Sure, i n theory, obviously they help make power. But notice the they don't tell you how much because it is so negligible. They do help keep gas/combustion residue out of the crankcase, which is good. I ran them in my race cars and liked them.
 
i've read of all kinda breather setups/scenarios and this option ads something non standard (more crank case pressure on the downstroke) & new to the mix

is it possible that on one breather setup all is fine but may be problematic on another?
Total seal rings
 
I run a Comstock reed valve screwed directly into the sump of my race bike motor , I use Total seal rings , no issue.
The original position of the where the breather hose would normally be is blanked off, the timing side oil flow holes are plugged, there is a 1/4" hole drilled under the oil pump, all works well
Regards Mike
 
I have them in my 850, No problems at all. I also have had no problems using valve seals on my exhaust valves as recommended by Total Seal.
