Are you just desperate to do some spannering or something? haha... The voices in my head are telling me to swop the stator out ! pmsl, the voices on the forum are more numerous... and they are calling for a battery swap lol

I have moved over to lithium batteries, they are lighter and hold charge for longer

I have moved over to lithium batteries, they are lighter and hold charge for longer Yes I have looked into lithium batteries I did buy a JMT lithium ion battery, but swapped it out for a gell one as heard stories of fires due to overcharging due to old style regulators? I know it has inbuilt BMS (battery management system) but just was not happy to take a risk? So itβs on the shelf for now, but most likely wonβt go to waste as it will be fitted in the Tigcraft bike, as was really shocked by the lightness of the battery and it sizeπ Would be interested if others have fitted a lithium battery and which one they fitted (Manufacture/model) and if they are using the original regulator rectifier or have a more modern charging system fitted like the Vape system that I intend to install on the Tigcraft project. Best wishes Al

Just ordered a Yuasa battery from Tanya batteries for next day delivery.
I will keep you posted π

If you've had the stator off an LC, don't forget you will need to set up the timing again.

It's an LC hybrid with ypvs engine π
One good thing about it as the stator plate is fixed

How about someone like Dusty do a pic thread on testings stator,reg/rec
Show step by step testing and what positions you need to Set the multimeters too π€

OK charged battery and is At 12.78
At idle it's 14.19 At 2000rpm it's 14.08 At 3000rpm it's 14.10
So a tiny drop when revving Does this sound good or no gain in volts as the revs rise a problem ?

Anything over 14v is fine. No problem. Try again with some load on the circuit, ie turn the lights on.

The clue is in the name
Sounds regulated to me π€ͺ

Some of the Japanese cars from the 80's regulated the voltage to just over 15v. I've never understood why that was necessary. Anyone?
Where as some of the Lucas alternators were regulated down to around 13.8v.
Both using a battery of 12v, nominal.

Lights on 12.25 idle 14.70 2000rpm
So with lights on I got highest reading

Lights on 12.25 idle 14.70 2000rpm All normal. This generation/type of charging system will rarely be able to 'keep on top' (when loaded) at idle revs.

Agree with the others, its fine and thats how these were done in the day, only added power off idle to combat the drain... lots of cars/bikes like that. Where as some of the Lucas alternators were regulated down to around 13.8v. Er, Gary, the 'Prince of Darkness' years... they regulated down to 0v not long after being put into use lol EDITED: personally not had much of an issue with Lucas products, but know many did... so that was me joking really. Anyway, pleased Martin took the forum advice and did the right thing.

Even though my old Varta battery and new Yuasa battery had same codes,the Yuasa was a good tight fit compared to the Varta
