Kris.....that will be a great build...

I don't suppose it will be long before someone does a 14:1 piston big build like this, which is now possible due to the Piasini Ecu, and moving the XT rev limiter.....and Dan at High Desert Dyno who built this engine for a Raptor.
Again, look at where the Standard XT rev limiter would come in at 7200 revs

awesome work, when u shift its gonna hit that much harder....+500 rpm = +500 rpm higher after the shift!

dl700 26-02-11 08:44

BTW the spring kit i sent in Richards head is good for 9k....

did they HAPPEN TO MAKE ANY CHANGES WITH TIMING?

what was the cost?

I am looking forward to my next mods now: Stage 3 air box, +3mm Throttle body, 105.5 Big Bore kit & Some head porting, That will help it along a little...
Also i am doing some highly needed front springs.

Kris

Kris found out today what it is like to ride my XTX with progressive fork springs, 15w oil, XTR rear links, lowered 25/20mm, there is a big difference compared to the standard XT's handling, I could not ride Kris's XT as hard as mine.

After testing the stage 3 air box today Kris wants one, boy I love spending other peoples money.

Sounds like you two have had a great day out!!!!!

We had a super fast ride back to Kris's house, he lives right in the mountains.:eusa_dance:

Advance +3 degree on all the range
Fuel +3% from 1000 to 6000, and -2% from 7000 up to revlimiter
Adjust revlimiter to my guess to 8000
Nothing else

Ok, Kev, is that dyno result that you posted just an ECU swap, or was it after optimising the fuelling?

and was your baseline map fully optimised?

CaptMoto 02-03-11 11:04

Excellent work everyone.

Kev can you please highlight what are the maintenance care procedures which an owner with a remapped ECU with higher rev range must observe to protect the engine now that it will work a little harder. Thanks
