Electric Start issues again
 
Hello everyone.
Hope some one can shed some light on the following .
I have a 2003 Fe501,
It will start ok kick starting. But im getting old ,so after about the fourth get off per day I would like to be able to start on the button,
So the mods I've made so far are
R6 Starter motor. New Lithium Battery. Taffys easy start carb Kit.
I am pulling the kickstarter back slightly when turning the engine over on the button to engage the decompressor as i have taken the manual decompressor off from the handlebars (I'm using that lever as the choke ).
No Luck it wont start.
I have put another spark plug on the HT lead (leaving a spark plug screwed in so it has full compression).It is generating a good spark off the button, So I assume it must be spinning fast enough.
I'm at a loss now, So any advise or ideas id really appreciate
Thanks for taking the time to read this.

Have you adjusted your valves you might need to.

Thanks ,I will check them tomorrow.
Can i ask though why would it make a difference on Electric start verses Kickstart

Rainerio May 2nd, 2021 07:20 PM

From reading everybody stuff here that is one the thing that comes up out of adjustment harder to start and if bad enough will not start. Not that big a deal to adjust/check

Hi .
Ive checked the Valve adjustments .The inlet were tight .
I have noticed that there is no play on the inlet rocker arm up /down or side to side (when the valve screws are wound right back up) .Is this correct as there is play on the exhaust rocker arm .
I am doing the setting from a cold engine is this correct?.
Thanks again .

Hi
I think i have put a picture of the stator up?

gozzo May 3rd, 2021 04:16 AM

The picture I’ve just put up shows rust on the pickups .Am i ok to sand this off without doing any damage. If so can i coat it o stop further rust?

Thanks Again

The autodecompression system should allow it to start on the button without having to use the manual or kick start activated systems. The 03's had a better autodecompression device but not as good as the 04-08 types. They were a vast improvement. If it were me I would install the 04-08 cam, autodecompression device and new ADC spring and make sure it is correctly pretensioned so that it snaps back nicely into its resting position and does not flop around. Your current ADC spring may have come unpretensioned and thereby rendering your Auto Decomp useless. At any rate is your bike truly a 2003 model? All yellow? If it is an 01 or early 02 it will be much harder to ever get it to start on the button.

Hi Husabutt
It is a 03 please see vin image. All plastics yellow.
I will take off the rocker cover box off and have a look at the decompressor
When you say instal 04 cam auto decompressor device ,Do you mean the whole cam aswell. Sounds a big job for my limited knowledge EEK.
Do you have any thoughts on the rusty Stator ,Is it ok to sand it clean. It is currently charging the battery at 14.59v at medium revs

if your decomp looks like this, you need a new one

Yes, the entire cam. It is O.K. to sand the rust off with fairly fine grit sandpaper. I have used 220 grit dry paper or finer. Afterwards you could clean the metal with acetone or lacquer thinner or just blow it off with compressed air. Keep it dry in there as moisture is the enemy of the SEM stator. Dry the stator cavity out after every wash. Some spray it with WD-40, others have coated the stator with petroleum jelly. Wipe off the excess with a towel.

The 04 updated cam and new style decomp worked so much better than previous attempts (89-03) that Husaberg then eliminated the kick start activated decomp. Once on my 05 when I took the rocker cover off the decomp was just flopping around, having no effect. I had never noticed any starting issue. I can only attribute my good fortune to the newer (04-0 eight) cam profile. It is necessary to remove the cam to re-pretension or replace the decomp return spring.

The 2003 model was not known to be a problem starter but as Ned has pointed out the decomp is a wear item. Too much exhaust valve clearance will reduce the effectiveness of the decomp. If your decomp is worn out some have placed a tiny spot of weld to build up the area. You can use a 04 -0 eight decomp with your cam if you want to. The cam may or may not need to be modified a bit by machining a little of the shoulder off. No big deal but for the same price of having it done you could probably purchase a updated cam.
