FE 501 00 on 1 wheel, hoy about the engine.

Ive just began to learn driving on one wheel. I dont come that long but two weeks ago the bearing in the flywheel gave up. Ive opened the engine to change all bearings and ballbearings. The piston had some scratshes on it wich I suppose came from the driving on one wheel. I wanted to ask you how safe is it to drive on the back wheel on an Husaberg, my first thought when the engine whent down was that it had to be a connection with my new skills. I would really wanna keep learning but is it dumb to do so with this kind of bike? Many of you having trouble with engines crashing couse of this kind of driving?

/philsson, new at this forum.

Hi Philsson!

Welcome to UHE!

It will help if you would tell us the year and model of your bike to start.
There are many here with tons of knowledge.
Just let us know some more first!

PS
This kind of driving is not considered as bad for your bike as far as I know.

The bike is an Husaberg FE (enduro model) without elektrical starter, production year 2000. The last productionyear of the old engine. I drive 50m at the time on the back wheel and I dont think it is that mutch to make a difference. People have told me that Husaberg just brake of back wheel driving and well, mine just broke when I began to learn. Maybe it was just bad luck and that the engine was going to brake anyway but it seems a bit dumb to begin practicing again if the engine is going to colapse once more. You have to excuse my english.

Would like some help also when it comes to ensemble the bike, wanna mount the timing chain right. I suppose there is a thread about this somewhere. But we can take this a little later.

Start by going to Husaberg Sweden for parts and service manuals.
Then tell your friends it´s a load of crap you can´t ride a husaberg on the rear. You have the best engine they ever made, but how many hours on it? Even the best die young... 150 hrs is probably pushing it...
Depends on how you used it. What cc?

Ausome video! If his bike does not brake of that then mine should last forever.
My bike has 200h + on it, changed ballbearings, piston, (vippor, rullar mm) The one thing not changed is the flywheel bearing, as far as I know.
As topic it is an 501cc.

the wqheelie won't account for the bearing failing. you could stick the front wheel on your bench, rev the engine whilst cooling it and it wouldn't do that.

you've just been unlucky. the bike is old. you've got to treat it with respect. how many hours?

replace all bearings if you really 'thrash' the bike. if you don't then you understand the risk you are taking.

Yes of course Im changing all the bearings and ballbearings now when the bike has colapsed. The bikes has a bit over 200h on it. But the bearings are already replaced at least one time. As far as I know the hole engine was renovated by the past owner but he did not replace the flywheel bearing, it was that that colapsed for me unfortunately. I was thinking about the scratshes om my piston, it must have somthing to do with a terrible bad oil fluid or something. Maybe the oil pump has given upp, that one of the canals is locked?

Aspen said:

Ok now I see you´re from Sweden.
Feel free to PM me, and I can get you started.
I´ll give you my email and phone nr so we can talk.
I´m no guru, but I can point you the right way...
At 200 hrs, an enduro bike is ripe for a TOTAL overhaul...
I just rebuilt mine at 150.
Just don´t forget you have a very fine machine in your ´00 501 !!!

try air filters that don't seal perfectly or the rubber sock etc. there can be many causes. measure the piston to barrel. although the barrel may be scratched it is the piston that wears.

you need to lightly hone the cylinder lining (well at least i do!) and check it out. go from there.it really does pay to go by the manufacturers tolerances and hours. the japanese taught us that.

excellent english by the way.

The piston is changed by the book. After 200h as it sais in the manual. The new piston has 50h on it and looks worse than the old one. The cylinder looks just nice.
