7600 miles engine inspection FE570

2010 FE570 7600 miles
20/50 V-Twin Moblie 1 motorcycle oil
Engine inspection complete disassembly
No problems, just had to see what makes this engine so great
Head work
Titanium intake valves and seats are prefect no wear. Never had to change shims for valve clearance setting. The valves could pass for new they are that good!! Iíve worked on many CRF Hondas and YZF Yamaha heads, The Husaberg's Quality is superior.
Exhaust valves , seats and guides were good, no wear
Used ABS Soda blaster to clean the head and valves
Mild port work, Just for my satisfaction not that I need more power, just interesting to experiment, Iíve done this type of work for years and yes I did make a very slight mid RPM improvement
Cleaned head and assembled with new valve stem seals. Did a vacuum check on assembled head NO leakage.
I did replace the rocker arms because of past experiences with older Husabergs. When I press the roller pin out, the pins was perfect NO wear on the pins so I could have used the same rockers
All bearings and the connecting rod are good, the wrist pin runs in the rod (no bushing like the older Husaberg). There metallurgy work must be perfect there is no wear on the rod or wrist pin. The crank had three thousandth run out, I aligned crank halves to one half thousandth .0005Ē
Oil pumps no wear . Clutch basket no wear from clutch plate tangs (I do run a Rekluse)
Every part in the engine looks good , no wear on piston or other parts, hone marks in cylinder looked perfect, very impressed with quality of parts.
I did have a small problem with the torque limiter a few months back, Itís been working great, I explained the fix in another post.
All the gear box parts look great no wear on gear engaging dogs or shift forks
Timing components showed no wear
Replaced counter shaft seal and water pump seal, these seal look ok but I replaced them while apart. Pump seals had no sand or dirt between them this time as they did before the fix.
I replaced water pump seals at 3000 miles the first time. Read my post on this if interested!
Part number for FE570 head gasket is wrong in parts manual CORRECT number is #78830036000
The 780 number is for a 450 I now have two of these before we got the right one.
Installed engine and cleaned all electrical connectors , I use dielectric grease on all connectors
Cleaned fuel tanks, The Profile tank filler opening filter is doing itís job, I did have some Crystal like pieces in the filter along with other small pieces in the filter sock, My fuel cans are clean this comes from service station pumps.
Checked all wiring for rubs, looks good. Replaced the Exhaust graphite ring that goes between the head pipe and mid pipe was worn out just a small piece remained.
Torque all mounting bolts and other bolts. Was not difficult to work on, just needs to be done Right!!
Went for a hundred plus mile desert ride Sunday ran it hard in the sand washes works great
My new suspension setup works really great for ME in the sand and desert trails I will do a post on it later.
Have a great ride

Excellent post, thanks for sharing. Any photos of the insides?

I have noticed the rev limiter on my 570 seems to be lower than a YZ/WR engine. I wonder if the lower revs helps keep the valves from wearing out?

Do you mean Profile or ProFILL ?

LOL ~ I ordered one of them of ktm-parts and it has been on back order for 2 ~ 3 weeks.

Davo
It's the Profill (not file) from the Australia good guys, these tank filler filters work!
I to have a couple of spare graphite rings order for a KTM 2010 sm-r 990 they uses the same size as the Husaberg
KTM is looking for them about March 8 same as Husaberg both part numbers are #58405005001

x2 on the Profil filters. Had one of these on the old XRR. Fitted new one and also pump filter to the 570. The design of the 70deg tank makes filling quite slow and tedious with the neck filter but a small price to pay I reckon. I'm thinking of going the diesel engine oil route at the next oil change, maybe Shell rimula.

Did you have any problems with the camchain tensioner? My '10 model is giving problems with only 18hrs on it. Just waiting for a DJH manual adjuster.
