2006 Arctic Cat 700 EFI motor rebuild advise

[cheatmaster300]

I purchased a quad with engine problems. The previous owner had pulled the motor and pulled the valve cover but decided to stop. I have done Arctic Cat top ends before but have never worked on the bottom end so any advise would be appreciated. What I have found so far is the connecting rod bearing is completely gone and some scoring on the jug walls. What i'm wondering is if anybody here has worked on these and if so did you replace all the bearings or just the ones that were for sure bad? Also is the 2006 Suzuki King Quad 700 motor exactly the same? It seems Suzuki parts are a lot cheaper to buy.

So you bought it with the motor out and apart? Where are you now with it, is the motor on a bench? Sounds like some cylinder honing and oversized piston rings. 

At that point, I would take it to a machine shop for small engines and have them check it out.

The motor was out but not apart. I currently have it completely disassembled and plan on getting the cylinder replated. I am also going to get the connecting rod replaced and plan on changing crank bearings.

is this a suzuki or arctic cat h1 engine?

I think the 700's at that time were the H1 engine, smaller ones such as the 400 were Suzuki. I know my 2007 400 was Suzuki motor

It’s a Suzuki engine. I have the ArcticCat 700efi 07’ model and cross checked most engine parts to be exactly the same as Suzuki LT-A700 engine from 05-07. Bought most parts from the Suzuki dealer. Just finished my top end rebuild with a Suzuki jug on this 07’ arctic cat. Hope your rebuild goes well.

BTW, there are a number of fantastic machine shops online offering Nikasil refurb plating and oversized jugs for less than 300$ with core replacement. They ship to you within a week, you ship the core back and get refunded. Great options with these bikes. Use the LT-A700 model, jug is the same.

So Cookie, something I've been wondering for a while.. Do they use jap electricals and electronics, or bosch ?
