880 Big Bore numbers?

All due respect . i have a 860 on my shelf with a cracked cylinder as well. Cylinders can Only be repaired so many times before trashing them, I also know that when an 860 gets trashed so bad it can no longer be restored to an 860 ,Some builders turn that cylinder into an 880.No- body has been building the 880 as long as I have. I have run and tested/tuned them solely since 07,not one skirt failure and i only use good cylinders. If I recycled cylinders I too would expect failures. Jus sayin, It take trust that your builder recognizes when to disgaurd a jug instead of cover her up with shinny plating.

Whos 860 cylinders are they? I might be interested in them! I think I ruined mine getting port happy trying to run a set of twins not made for the r. doh. :face-icon-small-sho

were does it say that?
you have a working knowledge and history of this motor?

is it an SHR motor?

seriously...ALL you guys are in 7th grade....BJ

Ok, my bad. It's not in the water jacket. It's the intake. Regardless, it's busted and it's an 880 cc. You can clearly see it in the pictures. Maybe it needed an extra .010". I am curious what happened. I have no experience with that engine.

First thing I notice on the E bay pic is the lack of porting,I see cylinders from several builders like that, And you dont think it dosnt show up on the hill, Oh it does.,lol :face-icon-small-hap
 
I think Visi brought it to light with his measurements........

so all the 880 bashing is over .010".............bore it .010" less and it instantly becomes this miracle motor.........open it up that .010" to the 880 and it becomes instant junk. :crazy:

I really don't get why everyone is attacking the 880? John builds a really nice 860 and has been building them for a long time... If you don't like the 880 go with the 860... Geez enough already.. I ran a CPI 880 way back in 01... Ran it for 3 yr's no problems... Then CPI had the bright idea of going to a 920 with stock cylinders... No worky... Trust me... Myself and a few others tried... It was a bleeder for sure... Ran hard for like 5 min..Haha! Still would really like to do a big bore shootout this winter... I am game to travel anywhere in the Rockies... I have both shr and trygstad sleds can bring both... I vote Cooke City Jan or Feb... Lets set it up!!!! I mean how fun would a shootout be if everyone had the same sled? To me it comes down to how I am taken care of when my motor goes down... Whatever the reason may be... Be nice if this site was just for talking about problems or personal dealings they have had with builders... Not bashing a product they know nothing about.... I really could care less how the builders make there products work... And I would guess 99% of you feel the same. I am running what I run because I rode them all before buying one... Thus the idea of a shootout...Haha!

In many engine applications that .010" can be the difference between "life or death" wether it's snowmoible engines or truck puller engines,or what every kind of engine you mod. I personally don't like that little gremlin in the back of my noddle when I'm out having fun "wondering" if she's gonna go or gonna blow? I don't know about you but I personally don't like green snow.:beer;
 
I like the idea of a shoot out, especially in Cooke City. Late February or March would be sweet. The Big Bore Brawlers!! :argue: BBB Shoot out!!!!

WOW...

Its just ENDLESS the grade skool vomit I have to deal with...

The worst part about Daves attack minions they don't know ANYTHING about engines...

IF you knew ANYTHING about THIS engine MACHSTER .010" bigger than the 872 is NOT a gremlin... the SHR880R will NEVER bleed green anytime sooner than the guy who cant tighten a hose clamp or pinches an oring during assembly...BJ:face-icon-small-coo

Grade school vomit? nice, real nice...spoken like a true professional? and I probably know alot more about engines than you realize but that's neather her nor there. you better get back to work cause your phone is ringing so much right?
 
BB shootout sounds great, but how are you going to do it?
-same sled
-same track
-other mods
-sled lighter/heavier
-clutching
-belt
-size of rider
-same snow/hill
-no poaching
-side by side and swap sleds/riders


Theres always going to be an excuse for the winner/loser.

I wanted to do one in Cooke last year at the Forum ride but it didn't pan out.

I know there will be at least one 872, and 2 860's at the Canadian ride so I will try again. Apparently we are going to hire a photographer so there should be some good pics/evidence.

So, how would you set up a proper shootout?

Im going to start a thread.

Ya it is tough for sure... I Have about the same list of things done to mine as you have... I am around 190 ready to ride. I don't have the 3in though..2.5 flexedge. I would do cooke.. 9 hr's but an excuse for a road trip.. We could do a presidents day ride? I just need a couple weeks notice to set up. Then we can all drink some beers an come up with excuses in person..Lol! I know a couple guy's with 880's on here that would show up.. Also know a guy with a carl's 900 in a new pro with a 3in that would come... And another 872... We will make the trip just need a date

I am in central BC and usually I am fortunate enough to be able to travel and ride all over BC...even made it to Cooke last year for the forum ride. This year I am swamped for work and it will be difficult to get out at all, but I am planning a trip to Squamish/Whistler sometime in the new year. You would love the riding in that part of BC. Our forum ride is in Sicamous/Revy this year and there are some USA members coming up. Hook up with them and tag along.
