The burden of truth lol.
If you read last years threads or the year before or the summer lol Beam, you get pretty much the same thing anyway.
The fix lol. Question comes up. Usually directed at customers but ends up different.
How many miles? How much HP? Then really the questions are just skirted because no one is willing to rip apart a good runner to prove ANYTHING about the product. You know like before and after measurements that everyone wants to know.
I think I now know why the HP questions are skirted too. Might be wrong but the Poo 800 does not dyno well. The motor makes decent power (we've all felt it) it just does not hold it a full load. Untill you know why (then you would have to sell it with the "fix kit") you won't get an impressive dyno number to advertise. If you post a good dyno sheet you will have to tell the customer how to reproduce it if they dyno it themselves.
Too much burden of truth I guess.
If you REALLY read what is there (not what you want to read) you see the best most proven set up is the guys posting with miles on the stocker. Ya right, that POS that you got out of the box.
Sorry but thems the facts right now. Some people are saying that they would love to have a reliable 2000mile motor lol. There's lots out there if you lose the blinders. Heck I'm 3/4 of the way there in less than a season and I definately don`t have 12 plus thou. of clearance. I don`t need to measure anything to know that. I`d hear it with the shop doors closed.
Mine has a "fix kit" though, applied since new. 32 to 1 semi syn oil use and enough fuel to show some color on the plugs from new.
Lots of talk about piston clearances in these threads too. Taper bores were used alot in the air cooled 2 smoke days. It was used to compensate for expansion differences of the barrel and pistons at max running temps. Maybe the Pro has this for that reason not a manufacturing error. I don't know. I do know no one has pointed out why this is wrong except to talk about cold piston clearances. I do know my engine reacts to load like an air cooled engine for cylinder head temps. I almost installed some old spark plug temp gauges but they didn't fit lol.
Cold piston clearances. Every manufacturer from Honda to Liberty does their homework and engineering to find out what's going on at running temps. They come up with ideal clearance and always err on the side of safe clearance for production. Why, cause some one might use the Mototune method of break-in or get too excited to let thing warm up after every start. Real world.
No one talks about running temp clearances. I'd like to know. I read about 4 to 6 thou lost clearance in a 1000 miles??? That's a LOT of wear. Seen it if some one forgot and air filter on a dirt bike and seen it when a piston cylinder was overheated causing too tight a clearance. But that's not wear that's a piston collapse.
Usually a piston worn out from dirt just slows down and dies with very sharp piston rings lol. Usually a piston that collapses it's skirt cracks that skirt if not replaced. What is really happening on the Poo 800? I still don't know after reading hours of threads on how to "fix it". Good thing is after a almost a season I still don't need to "fix it".
Performance gains? Since the first 2 skt was made then taken apart to search for more power the shim method (or lower piston crown) has be successfully used to gain port
duration for more top end power.
Longer rods can do the same with the added benefit of getting more air pushed up to the top. This usually adds to the power band and torque as well.
Then there's the ones we all know, added compression and pipes. All will certainly provide performance gains you just need to decide if torque or HP moves you and how much you got to spend.
If there is a fix or need for it i still don't know lol. I do know there are lots of stockers out there living beyond 2000 miles. Some of them in horrific conditions with only 60 or 70 to 1 oil ratios with EPA lean fuel and timing.
Those facts make me feel comfortable with mine.
