Might be a option for next season. Has anyone seen or tried this Big bore kit????????

Got 2 872R's in are group and they are brutes and very smooth feel like a real well tuned 1000.

My dealer has these in stock for the etec, I'm anxious to hear how they work, no fuel controller required. And pump gas comp ratio.

Talked to him yesterday and he made sound like a big friggen secret on the big bore kinda pissed me off talking like it was a prototype and only 1 in Canada and would not say whose it was and 3800 for it.

Did you talk to him at the show in Whitecourt? Or did you call on Sat?
They have the Trygstad 872 etec complete engine swap with balanced crank and topend kits for your own engine. The original poster just copied from trystaads webpage.
The complete engines are rare, and not sure on how many top end kits there are in canada. I know there is one currently installed in a xm, it's not mine LOL, and the owner of the sled wants to keep it a secret.

The problem with some of these "kits" was that many of the builders started trying out changes on the 2011 800 Etecs. The motor's had minor changes in 2012 that made the crapping backwards ass 2011's that they were developing not as significant on the 2012's. Put 2012 cylinders and use the 2012 gasket thickness on 2011's and it solves a lot of problems.

Yeah seeing as BMP waited 2 years to get their kits right I would think it might be a better option.

 

[Caper11]

Trygstad waited till this year to put it into production from what I understand, its hard to market something with so many changes made to the etec in the last couple of years.

Talked to him at Whitecourt with the sled there. Have since talked to him. Would not say where the kit was from over it now.

I love the idea of the big bore but I just cant see throwing 3 year warranty out the window.

I talked to Dave via email and he says the kits are now bullet proof! He said the one obstacle they had was the factory imbalance of the 800 engine. The pistons they have developed for kit corrects this issue? It sounds like they use a auxiliary fuel system to feed engine however he did not elaborate and I never asked? Sounded like they did not use any kind of controller? I think I'm going this route next season!

Sounds like they are using a "power jet" type of supplemental fuel delivery like on carbed turbos, etc?

We will be doing one for a customer this week Steve. The top end should be back to the shop tomorrow. Should have some solid info next week sometime as he is headed to Revy first of the week.

There is no fuel controller being used, and they recommend the stock exhaust, the complete engine swap program has a balanced crank and the t stat kit. Not sure how many engines are left. But they stock the top end kits.

I got a chance to ride my dealers xm with the trygstad etec 872 in it. I was very impressed, very clean running and smooth!!
even tho he was running stock clutching but had 20g of pinweight in it the sled ran awsome!! The stock clutching does not do that engine justice! Can't wait to see what it does with decent clutching in it.

I am running this kit in my 2011, sounds like you guys should just call Dave. I had nothing but a good experience with him on the phone, we went over everything, he was more than willing to explain his theories behind everything and no secrets. Sent him my cylinders, head and raves, and was returned a week and a half later, and so far i am extremely happy with it.

there was one with us last weekend in revy, not much said about it, and was asked to ride with us

also had a 872 carbed with us and it ran very well, that might be the sled to beat this winter, but he is also very light and a great tuner

Barry didn't change his by chance?
