24,000 miles on my Mastiff. 93,000 miles on my Chopper. Both running Amsoil from 500 service. Have not had any problems with the oil. I change it about every 5000 miles

Only 22 posts but I've been riding , racing , and making a living as a motorcycle mechanic since 1972.
Currently own a 06 Pittbull , 06 Ridgeback , and a 2012 Street Glide
Bought my glide in July and had over 10 k on it before the 45 day temp tag ran out
Not my first day!
Thats what we needed to know Mr. D
Throw us a bone
Need the info

As far as Amsoil goes, that was a long time ago and I think they have improved a bit since then. I myself have been running the 60w racing oil and have been quite pleased with it. But then again I haven't been using the bike for racing either....

With your type of experience your input here is valued.

Thank you! In 40 yrs I have worked on every brand. Including a couple yrs tuning for a AMA race team. However I admit big twins have only been the focus for 3 yrs now.
With a steel plate and 6 screws in my neck it was time to park the Race bikes
I'm sure Amsoil has come a long way but we did have several failures

Thats an Evo thing for sure!!!!!!:2thumbs:
Dude, you sound like the amzoil guy who blew up his bike. That means a lot of bikes should have blown up due to oil. The pits would have spread like wildfire about a certain brand not to use. You correlate a base gasket with an engine family is like saying you can't swap oil brands between each outer or those oils will blow year cycle up :roll: :rolleyes:

Hey, when I port my engine, throw in a hot cam, do I send in more air into the cylinder? I won't hold my breath you go answer it.

ok looks like I opened a can o worms so I will try and anwser all questions
1. Have you taken a ring off [carefully], checked gap at both ends? If no taper, what's the problem? Rings need a crosshatch. Skirts are lubed by splash and need no crosshatch.

2. Was the bike smoking oil at idle?

3. Was the bike smoking down the road?

4. Was there a riding partner behind you that was sniffing that burning oil?

5. Was there no rider, a car came up the side of you and pointed to his windshield with the wipers on asking to guide him home, you left half a quart on his wipers.

If there is no to any of these questions, who you gonna listen to, turtle talk or someone sees normal wear and can't put two and two quarts together.
no smoke at all!!it would use MAYBE 1/2qt 3500mi

Do you have a picture of this( what you call a small wear ring) towards bottom of cyl?
sorry I dont the motor guy has them now!! I called him and he said .005 would take care of it but I might get some piston slap cuz of the short skirts on the piston and w/ .010 i would be able to go to the next size piston

I have yet to warm up a car/bike with set tolerances needing to burn down the riding hours ???? :job: I never understood the many assholes [don't put yourself there if you are not one if them LOL], and no, you could not cut down the emissions, obviously. A tank full is a tank full. It's your beard growing gray you sit your life away not riding. A more air kind of mentality told you that fallacy. You've got the worms, I've got the hooks.
_______________________________________________________

Ring gap is between .008" to .015" and this is for the evo's compression ring only. 'Wear' we at with this one ring?

What is the piston to wall clearance?

See, I'd just change all the gaskets from the base on up. No new pistons or nothing. Why? Because it didn't smoke. I'd use the same rings over again. I wouldn't hone the cylinder. The smoother the finish, the better the seal.

Now, you take a bottle brush to that, you make ball tip lines all up and down the bore. You missed some of the surface, you still do not make a flat contact, but create more gullies or troughs than seeing the rings. It needs a constant flat spot, not roll over a gouge then seal over a flat [un-balled part] of the wall again.

Without a snap bore gauge, or a bore gauge itself with a dial; you are better off seeing that gap from bottom to top more accurately and faster with this style measuring tool. You go taking a feeler gauge to parts and come up [within tolerance], it goes back together. It didn't smoke then, it should not smoke now, sans the bottle brush attack and leave that for squidshit.

ZX 14 Compression Test - YouTube < This is more about wall damage vs. someone with less mileage, ran stock air cleaners and came up with 187 psi. Ain't no lie, now don't chew know I come withe goods like compress your ride, because down the road you are just a spot in the mirror, otherwise; is dis wise guy letting you knowattsup. :up:

Brew? You gethe joke! :flag::whoop:

Mule2 is the bike you get bit bye one. Wickedly fast, but you get used to it and want more. A ton plus within seconds is nothing for this bike, so the joke is the spidersaystay up or move outhe way!

WOT rolls INN is WATT PEE'd Out > Some Compression! And I'm more surprised at that number if you only knew. :confused:

Ever see "Vinny-Gearoon" ask a honeysqueeze out for a date; you want comical? :zwhistle:

Outdoors opened up a can of worms and all I am doing is contributing to the engine question. Guy wants to bore it out and I say it doesn't smoke. No wait. The OP said nothing about the bike smoking and I sort of figured that out? No complaint about, 'well it was puffing anyway so I decided to tear it down'; now looking at a .010'' over so hand over some money sort of why?

Something like this smacks pre and a post teardown with the compression/leak reading. It shows you went nowhere you come away with the same leakdown/compression. It's all about some oil destroys an engine, and who knows how many hours were on the rod, how many hours were on the piston? WOT are the odds and all that, lets blame the oil swap. And btw, did you watch the hydro boats run on speedtv today? What oil was sponsoring that drag event? And no, never used said brand. Just a minute oil test, so as to create a science lesson with a few new and old crude oils.

No offense, Mr. D, but that's how Lucas and dark got its name. Someone did not see vibration from that era? Missed the positive ground of one country and is imported to different nations? But to go thru the brit bikes I've gone thru to make 2 bikes, most every electrical part on those 45 or so year old parts were reusable.

And the joke is the oil. Because that bike with 220psi was mixed with straight 50w and half the other mix was what was ever left around; mixing those up too. And that is racing oil from the 1970's. No new SAE numbers to follow. 220psi right up the OL' Wazzo!

It's all on video me changing oils. So as I was trying to blow the engine up with any oil I had around, any break in I wanted, and it sure was not a book break in. In other words, D, you have you side of the story and I'm still building mine.
