Leo, I di not have a Hidria on my older bike to test, however it appears to me that the hall effect sensors would be in the FIXED pick up plate and not in the actual stator coils used for making the power. I agree that 7mm BTDC for a base timing sounds excessive, and yet it seems you have no other running symptoms or kickback.
If I am thinking correctly, moving the stator plate on this will not change the timing.
I would suggest contacting Chris at Splatshop via email to see if he can give you other info or ideas and possibly just throw a strobe on a bike for comparison. He may even be able to help with some parts to try if needed, as it seems you may not be lucky enough to have a lot of other Sherco's around you to swap parts.
Refer him to this thread if he is not already aware, as he is a busy guy it seems.
After this initial uphill trail failture I had doing my tests in a regular unpaved road most flat. Bike took about 5kms (3miles) to be at the point where rear fender start to melt. (Cruising at moderate speeds and load).
The buddy bike whitch rode with me never get close to it.
The heavy smoke has gone since everything inside exaust burned on first time.
Rear pipe oil has burned on first time this hapened. Now there is not much smoke beside regular 2t smoke.
No blocage at rear exaust.
I will start to look at some weired ignition fault. Since everyelse look ok to me, bike run greath and exaust keep overheating when ridding at moderate speeds
Pick up coil white/black 200 ohms. Blue/red 20 ohms. Anyone have hidria ignition specs and timming advance?
Thank everybody for the help untill now. Lets keep ideas comming.
But this leak is a old thing and the overheating started on last ride and spark plug color seems ok, engine temperature ok, the heat is only at exaust.....?
Have a 2015 300cc sherco. On my last ride noticed a hudge amount of smoke from exaust. And some rear fender melting. It was during a uphill trail at moderate engine load. Have done it many times before without issues. To me it is clear that there something wrong. Checked water level, water flow, fan working speed....ok. engine temperature and power nice. Start easy hot or cold.
When I back home checked rear exaust blocage, carburetor, gearbox oil amount, magneto key and everyting seems ok.
Than, checked timming with stroboscope. 5mm btdc just after idle and 7mm over ~3000rpm. This look too much to me! retarded the timming as far as possible but keep having same readding.
Can be too much advance causing this exaust overheating? is I am missing something?
Havent "kick back" issues.
always had few pinging when too much throtlle at low rpm
There is a leakage in reed valve rubber gasket....
