Thumper Racing 610 kit.

In the piggybacls I've heard about the JD Tuner from jdjetting.com plus a box from Bazzaz. Some reports of the Bazzaz over on the big advrider threads - people were happy with it

if those are the sort of things you're looking for?

i'm getting older and more confused by the day - you have the Husaberg User Setting Tool right?

Yes I have the User setting tool Kris, not a fan of it right now. I'll sus bazaars and jd out.
 
You can contact fp engineering in english Peter was realy helpfull/replied all my quistions and I am very happy about his service!!!
I even got a spare ecu with different mapping for free because I wasn't happy with the mapping on my stock ecu at first.
(I asked for custom map for the head tuning/and maybe later add bigger tb but was not so happy about the mapping with my stock tb).
The mapping on the second ecu was almost spot on I had it on the dyno and even AFR seems very good and very smooth throttle response (ecu for biger tb throttle felt snatchy).

Thanks fellas, looks like I'll get in touch with Mr Peter Foster.

Btw the bazzaz, power commander v and Jd look pretty similar in functionality.
 
Hey ... how about a Megasquirt or similar for an ECU? Surely those would work? They're what Dr. C used in his EFI conversion of the classic motor. I'm not 100% sure what they do and what they don't do but I believe they'll run almost any motor and sensor config, incl. both fuel and spark ...

And are 100% open!
 
Aha you may be on to something my friend. Time for a bit of googling.
 
My Vortex gives access to everything and is easy to use.

To be honest in tuning my motor we found that the standard Vortex ignition mapping was pretty spot on. We could only gain 1/2 - 1/4 hp with ignition changes. It was the fueling that the real gains were made. At least on my motor and the dyno.

the vortex works like a powercommander or replaces ecu??
There is no room to store anything so I guess it's a replacement for ecu...
 
Hey Chris thanks for the info. A piggy back jigger could be the solution in that case.
The vortex is a stand alone ecu, very expensive. FP's ecu is fairly pricey as well then there is micro squirt which is well priced but Im out of my depth as far as writing the paramaters for mapping.
 
I was looking around on the website from thumper racing but the 610 kit is not listed only a cp piston for stock bore or the expensive 660 kit....
I was just curious what the price whas for piston/gaskets/liner without machining the cylinder....
 
thx!
So for 1250$ you even get a complete cilinder with liner installed seems like a good upgrade when the stock cylinder is worn (at this pace with my riding in 20 years:p )

I found a part nr 81730038100 from ktm complete cilinder+piston kit costing 649€ (for stock 565cc parts)
I don't know if this is for piston+liner or if the cylinder itself is also included....
For only liner/piston it seems expensive, but if the cylinder itselfs is included it's a bargain!
I will start to save some money so I can buy some parts next winter before ktm decides to stop making/selling them for the bergs :unsure:
The 570 is a keeper so I have to start hoarding parts before it is to late lol
 
I'm quite sure that the official kit includes the cylinder!

Here's an example that shows the parts in question, taken from the parts book: Ref.01 - CYLINDER AND PISTON CPL. - 81730038100 - MotocrossCenter: Dirt Bikes, Enduro & Supermoto Store

Note that for the 104mm bore, the engine cases have to be bored out! Not necessarily such a terrible thing, I don't know!, but it's more work and more costs.

And one would probably want to do some form of balancing?

(as we're on the subject, the stock cases can take a 102mm piston/cyl)
 
Shame no kit or the 06-08 FE550 or are we talking grenade time for the bottom end ?
 
I thought the cylinder was the only thing that have to get bored out for the 104 piston and different liner ofcourse if it includes engine cases boring out and it's non reverseable (meaning you can't go back to 565 cc wit other cylinder. )
I wouldn't do it even though I would llike to try 610 one day:cool:

590 is to small of a difference IMO to bother:)
It would be nice to have someone with a 610 kit /stock crank with high miles to see how everything holds up.
I can live with a rebuild every 150 hours but if the bearings can't even survive that it seems a bit crazy:unsure:

Nice find that link thx:spin:

Click to expand...

Amen to that
 
I'd think you can go back to a smaller bore no problem, or at least I can't imagine otherwise. Mounting and sealing surely isn't any different, just clearance. Although I don't know for sure!

PEI Mudder, maybe there's some useful info here: http://husaberg.org/husaberg/19472-650-700-kit-do-yourself-thread.html ... although the 550's bottom end seems to be considered more delicate than the 650's? Maybe it's just the higher crank weight though ?

Cases not bored yay, just have to relieve the joins in the cases and then the liner is a slip fit in the cases.

The NJ207 bearings survive in the ktm 690 engines just fine. The big end will survive too, but nothing will last if abused or starved of oil. These motors make enough oil pressure to float a plain big end.

Application of a Ti wrist pin will offset some weight (we now have a big block chev sized piston rolling around in there. +18% mass iirc.
Or add metal to the crank counterweight, but I dont think you sumo fellas liked big slow revving tractors.

F''k you all. Now I dream/plan of going 610 again... And later add the crank for 660.
It just makes no sense. Except that it does...
