My fe450e came at last / help!!!

Mesut,
You should not have head shake at 50 mph. I would first check the suspension settings and sag. Try and check the front wheel runout and balance.
I would count on a new chain and sprockets in the near future judging by the grit on the chain. I have seen worse sprockets on a used bike.

It got hot fast?? Yes the motors will reach operating temps in a hurry. It did not boil over did it? You may have to rejet it for your altitude.

The bike appears to have low hours

The Berg engine IS a very noisy engine. If you have never heard one run before the noise can be a little concerning at first.
Check your coolant and make sure it is full. Full being just over the top of the core. Usually 10-20mm from the top of the filler. Do not fill the radiator completely to the filler neck.
The clutch should not creep. You may want to bleed it or flush the fluid. You will want to use "Magura Blood" or a high quality mineral oil. Do not use brake fluid.
Do you know if the valves have ever been adjusted?

Is that chain a little too tight.....hard to tell from the small pict and not see the whole length of chain. ???

Usually dirt bikes with quick handling/steering will headshake during rapid decelleration over small bumps. Headshake that occurs as you increase speed may be a sign that something is loose or bent.

Was the bike ever crashed hard?

Was the bike ridden in an area where it would be likely to hit an obstacle with the front wheel?

Is the front rim new?

Are the handlebars original?

I would start with the wheel bearings and see if there is any play there. Then steering head bearings. Chances are that if something is bent is will probably be the axle, triple clamps or fork tubes.

The swingarm could be bent also.

Look at all these components carefully for signs of impact.

Take the front wheel off and roll the axle on a flat surface. Look at the forks and see if the look parallel.

Read this:
CHECKING THE FRONT END

The first thing is a quick preliminary check which consists of sighting along the plane in which the forks lie. Gauge one fork tube against the other by making sure they are parallel. If not, try loosening the bottom triple clamp bolts and front axle and, if applicable, any fork brace, and twisting the front wheel back and forth slightly. Bounce the front end up and down a few times (make sure the top triple clamp bolts are tight!) to center the wheel, then snug the bottom triple clamp bolts and and then the front axle. If the fork tubes are still not parallel, then either they are bent or the triple clamps are bent. To find out which one is at fault, disassemble the forks first and rotate the fork tube in either a lathe or on V-blocks using a dial indicator, or roll it on a flat surface. If the forks are straight, put them back into the triple clamps and, if the triple clamps are indeed bent, lying a flat plate across the fork tubes will immediately show this. Both fork tubes and triple clamps can be straighten if not bent too severely. However, as soon as any crease or chipping of the chrome is evident on the fork tubes they are history.





Chassis Alignment Basics


Also if everything checks out before you tighten down the front axle pinch bolts, snug them up first and bounce them up and down then with a helper have him/her hold the front brake on and compress the forks a little while doing the final torque down. This seems to help align the fork tubes to keep them from binding up during their stroke.

Congratulant on your new stead. It looks to be a fine bike! Before you do anything drastic. Set up your race sag and set your fork to parallel, reset your fork clickers to the stock settings and just get to know your bike? Sometime your head shake could be just as simple as where you’re sitting on the seat? My 02fx470 used to have a bit of head shake under hard acceleration till I re-sprung it and got the clickers dialed in a bit closer. By the way how much do you weigh, is the bike sprung correctly for you?

I would have to agree with you on this one 70marlin, although husabutt's information is correct about bent forks and triple clamps leading to head shake, my bet is that it is as simple as your spring rates and riding ergonomics. I say this because I bought my bike new out of the crate and my first ride on it was a fast acceleration on the asphalt up to about 60mph. On this first acceleration I got a sudden case of headshake about 45-55mph to where I almost lost it on the blacktop.... and I had a Scotts steering dampener on my bike!!!!! I don't remember my position on the bike but I think I was sitting too far back on the seat and my suspension was set up stiffer than morning wood. Anyhow, getting the suspension set up and having your body positioned correctly in the saddle is probably all you need to do to fix you head shake.

Regards,

My FX470 had a damper and I could sit anywhere I wanted
without any head shake.Without it headshake would show
up randomly.On my favorite trail it might do it 1 out of 4
times,so I just kept the damper on it.Enjoy your yellow tank
while it is still yellow.I ran race gas for a while and it turned
brown.If I ran the bike much in the high timed ignition mode
it would spew a little coolant.But in the low setting it was fine.
I think it was just as fast,I just shifted a little sooner.

oops

The bike would'nt dare shake it's head with 15 stone on it :roll:

Hello Mesut

I bought a new FE450 3 months ago and was suprised how much engine noise there was but figured this is probably normal.
As for the head shake I encountered this after hitting a ditch awkwardly and when riding on the road above 60mph i thought it was going to throw me of. I found the forks had twisted in the yokes (triple lamps). It was an easy fix, slacken the bottom pinch bolts, kick the wheel a bit , pump the front end up and down with the brake on then tighten everything up and go for a ride.
Looks like you have got a sweet looking bike and I am sure you will enjoy it when you have it running your way.
