IT's probably better fitted here.Why was this moved?
Maybe I missed it, what kinda hp is this kit? cost?
IT's probably better fitted here.
I don't know the HP. I haven't seen a dyno sheet. Wayde's got these 910s for just under the $3k range.
The stroked 910 is a 962cc. It's a different type of project. It's in the $5k range. It's an ANIMAL with GREAT harmonics. I saw the vid of it racing a pump gas turbo on 7lbs. NECK AND NECK!!!!
I think Wayde will post his prices here.
Getting some spring hours on this and she's been getting better as she goes.
And now that I'm better at tuning the electronics, she's making more power and running cleaner.
How is the performance on the top end?
Feedback from alot of owners of other big bores claim substantial improvement in bottom to midrange with little, to no, improvement at the top. Not sure if that is a result of improper tuning or simply a shortcoming in the design of the kit?
It'd be nice to see a big bore package deliver for the Pro the way the Carls & Union Bay engines did for the Edge.
Just about the time I figured out that I was full of "error on the safe side" by running some extra fat numbers on the Dobeck, my TPS went totally crazy on my last couple rides in May/June.
No, those two aren't related, but it was a little of "went from one problem to the next". Lol
Nothing major and nothing to do with the big bore runability, quality or durability.
Summer updates from Polaris dealer:
checked reed petals
pistons checked (heads not pulled)
Can't wait for snow.
Yes I haD to replace my motor mounts , primary clutch, stator, jackshaft, and brake bearing.
My pipe has been rubbing on the frame. We believe that's what was causing all the DET issues. Those DET sensor are just a microphone and are very sensitive. It will pick up the vibrations from the pipe rubbing on the frame every time. I'll pick up my shed tonight.
When I wasn't getting the DET issue it freaking runs great.
Scott care to share the head stud specs or where you got them from? Nice build. That poor kid is in trouble seeing all that black magic at his age .
I know I'm digging up an old thread but how is she doing now? I'm tearing into a fresh wiseco forged piston built 12 engine i did to port the crank case and smooth up the transfer ports. Also takeing the steel plate out to install a custom aluminum base plate with pins between it. The block, and the head. Maybe a little late, but an old mod i have been doing for years is running a det sensor zip tied to my coolant hose. If in happy with tuning and doing something like a race, or high consequence climbe, I unplug the head mounted det sensor and plug in the one to make sure the coolant system is doing OK lol
