Hi all

I have noticed my bike has been running a little rough and seems to lack top end power

the occasional misfire etc...

I have had a play with the carby adjusting the idler and air/fuel mixture screws and got it damn close to specs.

I have noticed also that the battery does not seem to be charging so I ran a few tests and wanted a second opinion on the readings.

I am pretty sure the stator maybe frecked....

Battery - without ignition:      12.64     (battery is good but low)

battery -  ignition on:            12.54

Battery engine running:        12.36

Stator output @ 1000 rpm:   29.90  -  30.00   (fluctuating)

Stator output @ 2000 rpm:   45.20    (fairly constant)

stator continuity:                 nil

 

any feedback on these readings would be appreciated

Battery voltage with engine running should be around the 14.3V range

well.....

decided to bite the bullet and just buy new stator and regulator and be done with it...

at the least I will be able to rule them out as a problem and at the most it may fix it 

I am suspect that the charging system is not working as the voltage output is too high and has negative impact on the battery

also noticed when I am riding and switch ignition from "on" position to "lights" there is a fraction of a second loss of power and a jolt in the ride.

will keep you all posted

cheers

Yep regs for the bin I would only use Oem or cycle electric have cycle electric full system On one of my bikes
And just reg on the other no matter what brand you use Make sure it has good earth on the frame and clean the paint
Of the reg where the nuts bolt down onto it Should be around the 13.5 to 13.7 for your bike (carbie) probley
More for a later efi bike and as for momentary lost power from ignition to lights that's normal on evo bikes
It's the design of the ignition switch pole type it can be a bit better if you use a after market electronic type

thanks for the info perthhog

whilst doing the shopping list lol

I was also browsing the programmable ignition system.....

maybe later when finances permit

as for the ignition switch... that was another thing I was curious about

am I able to use the newer style round security key ignitions or are they different setup?

 g'day RED, i am a Pirie resident and have (last winter ) replaced charging system on my 87 evo, also fixed the cut out when turning lights on, .If you need any advice on evo pm me.

 

 

G'day Bob

good to know another local I can hassle for assistance...

we need to get together sometime for a natter and ride 

and thanks for the offer

Red

thanks perthhog

do we need to replace electrics etc to modify the switch at all

or is it just a clean swap out?

 

Red

thanks Bangkok Bob

message heard and recieved....

I really have no problem with the original ignition switch, I was only thinking for security that the round one would serve better protection.

as for the delay when switching, I can understand the reason for it now too

as it is being turned it is disconnecting one contact point to engage another

so temporary power loss is to be expected

thanks for the input and I will stay with original

it has lasted all these years and I have no reason to doubt it will continue to work

Even the Oem ones wear out bob that's why you use to be able to by the plate for the pole type switch
Separately for when yours is worn out , as for the slight lost of power I agree with you once your awhere of it it's no big deal

another thought on the lack of power
I recently replaced the exhaust system
the system that was on the bike when I got it had no baffles in the mufflers

and was extremely loud, I know loud is good so others can hear you coming

but these sounded like fire crackers going off and definetly a cop puller.

I have since changed the whole system with baffled mufflers
I can only assume this would be creating higher back pressure and may be choking the engine
which brings me to my next question....

Would I be right in my assumption that the jets would probably have been changed in the carby to suit the old exhaust system
and now need to be replaced to cater to a baffled system?
