2001 470 overhaul

ORBerg · Feb 9, 2007

Hello all,

I've been a 5 year lurker of this list and want to thank everyone for their experiences and insight on the care and feeding of the Husaberg. Without you the bike would have been a door stop years ago.

I've had my '01 FC470e since new. The cam and rockers were upgraded when they went. The decompressor has been upgraded. The cam sprocket and chain tensioner have been upgraded. I spent a long time trying to seal the cam cover. My SEM has not yet failed!

Anyhow, after 150-200 hours with no bottom end work, I was planning to rebuild before the racing season starts. So my question is, what does a short stroke motor need after this much time. And so you know where I'm coming from, the price of the OEM rod kit, OEM piston and upgraded counterbalancer ($500!!!) may cause me to scrap this thing. Any and all opinions on what needs done are appreciated.

I have to admit, by biggest concerns are the parts prices (truly outrageous) and the fear that I will rebuild the thing and it blows up withing the next 10 hours which seems awfully common from reading the list.

Thanks

Geoff

well it is just like a car. If you feel that it has been a good bike, and there really is no reason that it should grenade, (if it is rebuilt correctly) and you think you can get your money's worth of riding out of it, then do it. but if the repair will cost more than the bike is worth and you are really that nervouse about it grenanding after you dump the cash, cut your losses, scrap it and put the money toward something else. problem is with these bikes that they are worth A LOT more to you than they are to anybody else.

give BOSS a call ang pick his brain.

Sell it while it still runs good and save your money for a nice down payment on an '04 or newer Husaberg.

Like Risky said, the repair parts alone are more than the bike's value.

Husaberg engines are easy to service.There are only a few gaskets required to strip and reassemble the engine,which makes it fairly inexpensive to have a look inside.If you have reason to believe that it needs a complete rebuild it may be practical to do so.If you are only running it 30-40 hours per year it may need only few bearings a set of rings and a few gaskets you may get many more years of service from this bike.Only you know how you have treated it and how well it has been maintained.
Usually ,unless there has been a major failure,such as rod breakage, it is practical to rebuild.You also need to ask yourself how long you want to ride this bike,they do keep making them better and maybe its time to upgrade.
The quality of the rebuild is very important, get professional help if needed.If they can keep airplanes flying for 50 years on the strengh of regular maintainence and quality rebuilds you should be able to get more than 5 years from a Husaberg.

priority
big end renewed
measure piston. if within tolerances in the owners manual = just rings
new bearings throughout the gearbox including washers.
cam bearings
the counter balance bearing -renew and upgrade if possible

the rest you can take a chance on but none of the above. i reckon the mains are good forever and if they go they'll warn you - it'll be a pig to start!

Thanks Taffy, that is what I was looking for.

The mains are inexpensive, so would do that while i was in there. I assume we can get the big end bearing and crank pin commercially. Anybody reuse the rod and just replace the bearing? Was it successful?

Also, I've read on here that the short stroke motors have not had the same problem with counterbalance bearings that the long stroke motors did, so was looking for the collective opinion on replacing the countbalance bearing on the original balancer.

Thanks again to all.

Orberg, IMHO, if the bottom end is not making a bunch of noise, don't mess with it. An exploratory look would not be expensive, if all you are needing is piece of mind.
