News / Sherco 2018 tall guy mods
« on: May 11, 2018, 10:49:56 PM »
How made some changes for being a little tall for the bike?
I'm 193cm and don't feel 100% comforts on the bike.
The factory has already the 2cm taller seat but it feels like the footpegs are much to high.
I changed them for 0.5cm lower ones but it isn't enough.
Also raised the bars 2cm
How of the tall people made some changes that worked?

My 2018 factory 300 has also this synerject ecu at the same place. This universal synerject m3c ecu is used by a lot of manufactures like ktm piago sherco Ducati etc.
By the new sherco two strokes it's only for ignition and powervalve control used.
Maybe get is building a unit for the two stroke as well:-)
The power of the factory is much lower then the older models.

Yes with the stock jetting it's the same.
I found it's the same noise as pipe bang.
I have pipe bang noise under little load.

Sherco Tech / Strange noise of iddle sherco 300 factory 2018
« on: April 22, 2018, 10:42:20 AM »
I have this new factory 2018 edition with the newer two stroke engine the 300.
I have this strange noise off iddle wenn driven and when I shift gears. It's a bogging noise no detination but like bok bok bok.
Most two strokes has this only cold but my bike also has it hot.
I tried little pilot jets needles with larger starting diameter.
When it's lean it's less making this bogging noise but it still does also lean.
I ride at below sea level only and with nozd needle and 42 idle jet and 172main.
I used motul 800 and changed this morning to motul 710.
I have also a lot of spooge that's also strange
Its running a little better cleaner with the 710
But still this bog noise off iddle when driving at low speeds.
I can feel the crankshaft hurting with this noise.
Maybe someone has a idee what it could be and what I could try to change it

Orherwises the factory 300 is super

Sherco Tech / 2018 models new powervalve left side????
« on: January 24, 2018, 12:34:01 PM »
I have seen on the picture from the 2018 models that they have a new powervalve assembly like the 125 with the drum i think.
Nowere they talked about this part but as you can see on the picture the powervalve cables are on the left side.

Somebody has some news about this?

Sherco Tech / Re: Powervalve opens to late at high rpm
« on: November 30, 2017, 10:57:45 PM »
Hallo

This sounds like  an earth cable problem
Cut the wiring cables open from battery to cdi unit.
And check the earth massa -minus from the bike of the soldering half way is ok.
Is the little wheel with two springs ok at the powervalve axle?

« on: October 27, 2017, 10:13:46 AM »
Hello

Im building my bike togheter after a check off the cilinder powervalve etc.
I was adjusting the powervalve and have seen that the second spring is thin almost snapped.

Do i have to take the cilinder of and the powervalve system?
Maybe someone replaced this sptings allready
Also i will replace the litte latch etc.

Yes i disconnect the swich and didnt make any difference.
We are for the 3 days enduro trip in france
I took my 1990 husqvarna the night before the trip out of the barn.
It is a really nice bike and climps the mountains really good.
Yesterday we rode a part off the WK enduro in the woods whit lots of climps.

Again an update
The bike was for 3 days to a dealer.
Now its got even worse
We tried everything but no top power anymore
The powervalve is not the only problem.
We have openened the powervalve by hand and blocked it so ots always full open.
I have the power of an 50cc moped
Whe swaped carb exhaust ignition coil sparkplug etc etc.
Cut the complete wireness open and checked dor issus.
Nothing we found.
I suspect the potentionmeter of the powervalve
Could it five a falsch signal so the cdi makes a wrong ignition timing?
