leg is good the most annoying for the moment is still neck/shoulder.
Just did a last ride with my bike before it goes to dyno something is realy wrong with fueling sometimes when I roll of the throttle wel not sometimes but a lot of the time... when I want to pick the throttle back up again the bike hesitates and it feels weak....
It starts fine it runs nice on idle and when the bike is accelerating it doesn't "stutter" but picking up throttle or from idle to reving horrible throttle response sometimes no acceleration in the beginning of twisting throttle...
 
I found the cause why the bike ran so crappy since I installed jd jetting:eek:
While the tank had to come of I adjusted the valve clearance because inlets where a bit tight....
And I got the cam 1 tooth wrong on the chain so after setting it back correctly big improvement:p
At low rpm it still does not feel great but I whent out for a ride with some "fast" crf 450's and when I gave my 570 WOT those 450's where seriously left behind me:cool:
1 more ride/oil change and than I get it custom mapped on dyno I am sure the bike wil get 65+ bhp because I know that dyno is a happy dyno:p (tovami).
On the dynostar I whent before just to get a run the bike made 62 to the wheel but is way less "optimistic"
 
got the gpr steering damper kit....
The instructions included are worthless....
I found a good install video on youtbe on a ktm....
But in that video they can re instal the top triple clamp same height as stock in my case this is impossible the difference is about 5mm because the piece where the pin attaches to + other washer ad height...
Because of this and the bigger risers my bars are rised by more than 20mm
And not sure if this is ok for the bearings/stuff everything feels smooth but it is strange that I cant install it like on that video...
My fork legs are just flush with the top triple clamp now....

I contacted gpr and my steering stabilizer is gonna be pretty expensive after all...
this is there reply:rolleyes:
Do u have the 70deg 09-11 husaberg? If so the kit u have is for a 12-13 husaberg(ktm one)
 
The bike is finished on dyno a lot of work to get it right in the end the jd jetting kit was removed and the ecu reprogrammed with user setting tool.
Result same as before all my extra mods 62.5 hp and +- 57-58 nm torque but it is very hot now and according to dyno man that could cost me up to 2 hp compared to cooler conditions...
The difference is it keeps it power for longer it revs all the way to 11 000:eek:
Still making + 60 hp at 10 000 when I see 8500+ revs on my trailtech dash and listen to the bike I feel like it is gonna explode already according to the dyno that's where I have to be:eek:
7500-9500 rpm is best range to be in higher gears definetly not below 7000
 

Dyno sheet now I have to find some time to actualy ride it:rolleyes:
Been realy busy lately my bike is still dirty from a ride almost 2 months ago so not like me:p
Hopefully the hours on the dyno payed of and bad throttle response on lower revs is improved:)
 
here is the very first dyno sheet of my bike completely stock except for radiator shroud mod and fmf pipe ecu "aggressive" mapping from dealer;)



The latest one is with:
-complete fmf system
-Dna filter
-390 airbox
-seat mod
-carillo higher comp piston
-Worked head
-Ecu flashed with 450 map for higher revs and custom tuned with user setting tool
-carillo slow rod (because it's 50gr more weight compared to a stock one:p )

The almost stock bike was realy good to +-6/7000rpm at 7000 they are at same level hp/torque.
The big improvement is starting to show from 7500 rpm and up now I will leave it for a while the way it is lets say at least one year:):p
But I still wonder what the effect would be of a 610 kit could it match the power the way it used to be around 5000rpm without losing topend I don't care if the extra 45cc don't get me 2-3 extra horses on top but it would suck that it wouldn't even make 62 hp no more:p
 
Just do it mate (610). There is a 18% weight penalty with the bigger stronger 104mm cp piston but.... I made 62 hp with the big bore only. Wish I had made a base line run first. I should return to the dunno to see what I have now.
 
If you have a stock rod with your 610 kit I am pretty sure the complete crank/piston assembly weight is pretty much the same....
The 565cc carillo piston is already +-25 gram heavyr I would say pistons itself are almost as light compared to stock but the pin is much heavyr that + the carillo rod ads +-80 grams probably around the same weight a 610 piston adds :)
Would like to try a 610 one day:giggle:
 
Just finished my 1st testride...
I wish getting it dynod/ mapped correctly wasn't that expensive but must say it was worth it!!!
Bike runs so much better now throttle response nice and smooth all the way feels more torquey even sounds different (intake ).
It even did a 4th gear wheely when I wasn't even trying to wheely:p
Before this I was considering going back to stock piston next winter or 610 kit...
But must say I am happy with the bike again as it is now:)

I also hope to take it on a trackday or 2 this year :)
Only did 1 so far this year with my gsxr on a new (for me) track and it seemed like a fun track for supermoto to:cool:

Sounds pretty! What's your gearing? And what the 390's airbox do? I read sg about it but only remember sg like it makes the engine more torquey.

Ok for me but I will make some updated pics soon bike looks a little different now (black seatcover with seatmod+back to the black/blue chrome plastics and some small changes....)

My gearing now is 14/43 I found this gearing very short at first but now I know my bike revs to + 10 000 rpm it's pretty long:p (I get almost 170 km/h at a good 8500 rpm).
How /what the 390 airbox effects I realy don't know I just wanted to try it...
I am pretty sure the 390 airbox will not give you a higher peak hp number though maybe some gains in mid maybe even sacrificing a little top end power???
Somebody else has to find out:)

Ok but what the more lenght do?
Click to expand...

In short there is a pressure wave moving through the intake and by changing the length you can time that wave to help get more fuel-mix into the cylinder. But ofcourse there is no perfect length that is optimal for all revs, so what you gain somewhere on the curve you will loose somewhere else. So this is a change of characteristics more than an overall improvement.
