The way this was "talked up" I was ready to put on the RayBans to look at the polish on these ports. After seeing them I am "underwhelmed", to me this is the minimum they should be taken to to achieve "exhalted" status . Aren't all the paid porters working to this minimum standard ????
Now, where are the timing #'s ??

Some porters don't believe in polishing anything, except maybe the top of the piston in some cases and the exhaust port.
I've talked to guys who've run against Ricky's saws though and they tell me they're fast...
 
sometimes there more to his saws than meets the eye. those of who that know what im talking about will agree.
 
and also, those who are non-plussed by the work, might also like to know that this is an old thread and that Ricky likely carved up that one maybe 10 years ago. I met him in 2006 and he was out of racing then.

i've never heard any of his run, but i have seen the wall of trophies and ribbons awarded for top performances.
 
Nice to see you solved the mystery Brad. Same thing I would have done, when I see a puzzle I gotta solve it. Nice saw!

I agree with you JJ & thats cool. I was just expecting to be "wowed" by the shine and meticulous work, not that "shine" alone is what makes a saw fast. The job is definately neat & tidy.
I think it IS important to make sure it is smooth (no necessarily mirror finish),flow is critical IMO, his looks real good. I don't like seeing port jobs left with no finish work done after the grinding seems incomplete to me.

in my old atv 2 strokes when they were ported if anything got polished it was exhaust port only ,and that was only to minimise carbon build up ,you want the grinder marks to help mix the air up and fuel ,this work on this jug looks very nice in my opinion ,the exhaust is smooth enough doesnt apear to be building deposits so polishing wouldnt increase any hp
 
theres a lot of saw racing in middle tn and lots of saw builders around

Where & When? ANy links to schedules etc? I am jonsen to take an event in live....

I was about to say the same thing. Although my knowledge is more 4-stroke/auto related, but any runner that has air/fuel moving throuhg it you want to leave a rough texture to help increase fuel atomization. Of course new FI car engines w/ the fuel injected nearly directly into the cyclinder are changin that. We polish the intake manifold runners, but leave the cyl head rough. Exhaust runners get as slick as you can to resist build up and aid scavenging via high velocities. :)

iirc Ricky said around/in/of the county fairs. Fall. Plenty of time to polish your ports (or not) and do those super secret *&^%$ modifications.

what's the chainsaw equivalent of racing stripes on a car/truck? do that too.:hmm3grin2orange:

White Co/Sparta here: 2011 Fair Schedule

Overton Co. I can find 2010 results but no "schedule". Appears to be late July or Early August. anyhoo.

Those are the only two I've heard of.

I never decked a case, but always decked, the bottom of the cylinder.

I still have that 031 cylinder and head want to buy it? I think, I still have the saw. You will need a 066 carb and intake boot for it..........$$$$$$$$$$
