Looking at getting my engine completely rebuilt in my 800r Ptek over the off season. Just can't decide which route to take.

 

The sled definitely should have the crank rebuilt as the sled has 12300 miles on the stock bottom end. I rebuilt the top end about 3000 miles ago, didn't blow just did it so I wouldn't have to worry about it.

 

I was looking at Rk tek's 860 big bore kit which I thought would be awesome. I am expecting to spend around $2000 which puts the big bore on the list but it leaves the crank out of the equation which I can only imagine would be a recipe for disaster.

 

I was also looking at MCB's full rebuild which covers everything and I'd have a fresh motor top to bottom, it's right around 2 grand too. But it's not really gonna bump my power up.

 

Anyone know of something I can do to get a little extra power and a full rebuild for around that price? I definitely want something quality so maybe I don't have a choice.

 

Let me know what you guys think, I'll probably end up going with the MCB kit unless I can work something out with RK tek where they do the 860 and a crank rebuild for under 3 grand or something. Just figured I'd make sure I'm not missing any good options

 

The sled is a 2008 Summit 146. Technically it's an Mxz but I put a tunnel extension and t-motion 146 skid in it. So most of the miles were trail miles.

You could always look at RK Tek’s drop in kit. Still a double ring piston kit can do it with new head $845 or use a cheater head (stock head sent in so it’s a little cheaper) gives an extra 12 hp and then do you bottom end.

MCB can bore your jugs, do anything you want. Call Scott, tell him what you want to improve,  and your budget. Pretty sure you will be pleased.

Give Big John over @ SledHeadRacing a buzz.........

True the crank, or put a Etec Crank in it
Repack with fresh grease
Fresh top end
Keep ripping the sled

Do you think getting an etec crank would be better off? or should the ptek crank do fine as long as it's all new?
