[QUOTE=BIG JOHN;2843096]hmmm
I would need JVB's name (a pm is OK) to verify story/timeline/problems...I also never said "faulty pistons", yes I have moved from cast/cat factory pistons due to some skirt failures , best yet is over 5000 miles on a 860 kit...the new Hyperdrive piston has had 1 failure in 2 seasons...pretty happy about that...as for having a motor for 3 months? (need cust. name to verifty this and why- I keep detailed notes on all BB motors)...not answering phone? (sorry, that doesnt happen here)...warranty? (I warranty MY work, not the customers or choice of fuels etc.)..its a MOD...no wty is expressed/implied...
In closing...I spend ALOT of time/money making MY customers happy...I offer the best of products/service possible...but the old saying still applies..."you cant please ALL the people ALL of the time"...:face-icon-small-win-BJ
First off it can only be a myth if it is not proven? Am I correct? If we touch the Loch Ness monster even once and could verify it, Is it a myth or a fact?
I would say much of what you are calling a "myth" Bj have been proven issues. What failure rate makes them okay for some people have different standards ?
I have had an 880 and it ran well, I have had a 880 cylinder develop a hairline crack on me too. I know of a couple of other guys with different engine builders that have had a similar issue. Is it wide spread? No, But it has and does happen. We tried a lot of diffrent things with our 880 in the beginning and finding a piston was one of them. Many things were learned after a few sets of pistons. You're welcome what we learned I am sure helped everyone in the 880 world.
I have had a lot of fast sleds that worked very,very well in the mountains here in Colorado. Are my sleds the best for every Tom,Dick and Harry out there? No, but my sleds are ran hard and run well. To put it bluntly I have a put up or shut up attitude when it comes to sleds... and there have been a lot of quiet people around me. At the drag races to the mountains our sleds have performed well. I have successfully ridden in the backcounty sleds that have won Open mod titles in RMSHA, that went on to spending a few years being ridden hard by me in the back county and where did it go to be put out to pasture? Was the sled toast? NO, It went back east where it won Hill drag title after Hill drag title.
All of my nasty, hard running backcountry sleds have had one engine builder.... Dave Trygstad. I learned about Dave in the pages of Snow Week and when sled racing was bigger from drag racing to cross country.
Back before the internet was cool..
You can call me a Trygstad Cheerleader..... You can bet your a$$ I am. He has my full respect.
What it is that I learned to respect about Dave is his commitment to quality, to bringing the best possible product to the table in his eye's. I have never been stranded by a Trygstad engine and I have run 8900 RPM 800's in the backcountry to wicked big bores. It is this commitment that brings me back to his builds time and time again.
My point here is if you are okay with thickness of the walls on your 880's or the how welding on heat treated cylinders affects the temper. Then they have met your testing standards.
That does not mean they have met everybodys standard's! Its why we have Ford and Chevy.
Not everyone would like my personal sleds, but everyone will like Dave's commitment to bringing a quality product to the customer.
If you like BJ's stuff use it he is a good guy and builds good products, but dont call another persons results from their testing "Myths" they may actually be true.[/QUOTE] Agree He stated his findings on HIS web page that WE went to .NOT A OPEN FORUM .O well that's the internet:typing: Pick your builder and enjoy .I'm cant wait for the snow it's going to be awesome winter 872 with new race clutch,Trygstad Ported 800r and my fun sled is getting Trygstad porting too, 08 Reny 146 600 sdi .Cheers
