pete roper Posted March 19, 2005 Posted March 19, 2005 A few weeks ago someone mentioned the fact that the late model Guzzi pistons seem to have some sort of teflon coating on and I scoffed as to it's long term durability. Well, I stripped my little hot-rod down (Again!) yesterday as I've decided the short stroke crank and Carillos belong in a race bike motor not in somethng for a fat old gumby like me to ride on the road and the RAM big bore kit I put in a few months ago, which had teflon coated piston skirts now has non-teflon coated piston skirts just as I expected. How many hours has it taken for the teflon to wear off? Well, I wouldn't of done more than six hours riding on it since I built it, (I know it's sad but I far prefer my 'Vert and SP to the hot-rod!). Anyway, if anyone would like to see some pics I can post 'em to somebody, Jaap has done this before for me but i won't bother him unless there is interest. Oh, has anybody here got a spare 88mm big-valve piston from a Mk IV/V/1000S knocking around. I need one to make the second string short stroke race engine work as it's CR is currently 6.4 to 1 Pete
txrider Posted March 19, 2005 Posted March 19, 2005 This may not qualify as teflon coating but recently I had a guy build up a stroked small block chevy for my truck and he wanted to apply a coating to the pistons, valve springs, crank, the works. He was using do-it-yourself coatings so I declined after checking this with a couple of local big name builders who said they hadn't been able to keep the stuff on. There are some reputable business that do a good job of this but it takes a lot of research to find them and then it's debatable if the additional cost and necessary prep on the pistons is worthwhile in terms of benefits received.
Steve G. Posted March 19, 2005 Posted March 19, 2005 I read somewhere that Fram oil filters is having issues with their teflon impregnated oil filters, the stuff is coming off and clogging oil journals or something. I can't confirm this, of course, so will stand corrected either way. I've never been big on telfon additives you put in your oil. As I see it, if the stuff was real good, all the oil companies would have it in their oils. Ciao, Steve G.
gthyni Posted March 19, 2005 Posted March 19, 2005 if anyone would like to see some pics Yes please, we all love educational pictures.
Alex-Corsa Posted March 19, 2005 Posted March 19, 2005 Yes please,we all love educational pictures. I second that
DeBenGuzzi Posted March 19, 2005 Posted March 19, 2005 Pics are worth a Thousand Words, Unless its a Bitmap then its way to huge and you could probably post 2 thousand words.

My brother rebuilt his truck engine once, used teflon tape on various bolts. Teflon came off cause he didn't trim it- it clogged up the oil galleys. My brother did another rebuild on the engine.
pete roper Posted March 20, 2005 Author Posted March 20, 2005 Yes please,we all love educational pictures. 46562[/snapback] Goran, do you know how to post pics? If so I'll send 'em to you and you can fling 'em up to save Jaap the grief! Just ping me an email to motomoda@austarmetro.com.au and I'll reply with pics as attachments, I'll try and keep 'em small J-pegs but I'm hopeless with pooters so I apologise if they are big. Pete
Skeeve Posted March 20, 2005 Posted March 20, 2005 I've never been big on telfon additives you put in your oil. As I see it, if the stuff was real good, all the oil companies would have it in their oils. Ciao, Steve G. 46557[/snapback] I, OTOH, have had *excellent* success with Slick 50. Don't forget that you have to shake up the bottle real good before adding the oil, as the teflon comes out of suspension over time. Besides that one caveat, I have yet to find another oil as good as Slick 50 in its only appropriate application. Unfortunately, it's about 1,000,000 times more expensive than the standard alternative. But I stand by my words: for filling the oil dispenser for lubing the chain on your chainsaw, Slick 50 is the best! But used motor oil is still the cheapest and works 80% as well; for the price difference, unless I'm going to cut some real hard/tough wood like hop hornbeam or oak [no african blackwood trees around here, but that'd be another good candidate], the Slick 50 stays in the chest & I just recycle my used motor oil for this application. But don't let anyone ever tell you Slick 50 is snake oil! Chainsaw oil, yes, but snake oil? Not hardly!
Guest Nogbad Posted March 22, 2005 Posted March 22, 2005 But don't let anyone ever tell you Slick 50 is snake oil! Chainsaw oil, yes, but snake oil? Not hardly! 46625[/snapback] Probably just the carrier oil they use for Slick 50 suits the chainsaw. Can't see the teflon doing anything. You regularly get cockfights on other bike sites over stuff like this, Slick 50 and other crap oil additives are a good subject, the other one is tyre sealants. It's just like religion, you get the believers and the atheists at each others' throats!
DeBenGuzzi Posted March 22, 2005 Posted March 22, 2005 What about prolong (or anything of the sort) is that stuff a good idea in the car or the bike? I've been thinking about throwing it in the bike and tire sealants? like that green crap? why would I want to add more weight to the wheels. Maybe throw it in a harely they have very little performance concerns and then you have one less thing to look over when it breaks down on the side of the road.

Isn't that the herbal Viagra stuff the spammers keep clogging my inbox with? Whatever floats yer boat, dude... As for Slime: that stuffs for tooobs! Don't put it in a tubeless tire, it's a waste, just carry a plug kit & one of those sparkplug-inflator lines. If you have it loose in an aluminum rim it starts eating the aluminum, so if you get a flat, get home & replace the tube *now*, not later...
DeBenGuzzi Posted March 23, 2005 Posted March 23, 2005 No no, this stuff, I know there is something else out there similar but I forget what its called. Just wondering if this is just snake oil and I shouldn't be throwing my money away and save it for tangable things , .... for my guzzi

Stop wasting your money and buy some accessories!
