KLE running problems

[rockmonkey1]

Hi all,
Been out on my kle today, and started having problems it fairly randomly starts running badly then just stalls, then it will usually start again fairly soon. A guy in a bike shop said he thought it may be the regulator rectifier? Does this sound possible? Any help would be awesome! Cheers!

Need more clues?

What voltage is the battery? After a ride.. and let sit for say 5 minutes? (12.7?) After being ridden with the engine running (14?)

When the fault occurs;
How hot is the regulator/rectifier? (check its temperature when things are operating normally before the fault)
What voltage is the battery?

Is the fuel tank full or near full? (could be a vacuum forming in the tank causing fuel starvation? Undo the fuel cap - if you hear a hiss you have a vacuum forming.)

Other possibilities .. if this only occurs when things are hot then
Ignition coil, black box, engine sensor...

thanks for that, i'll check the temp of the r/r
others things i thought it could be are
-i had the tank off to put in a new air filter, may have put the breather back wrong
-ran on reserve (forgot to switch it back thought i'd drain the carbs to check the fuel
-i put a 12v socket on, any chance this isnt helping? not that i have used it alot yet!
i went for a ride the other day, and around 80 miles from home the exhaust header pipe came loose, rode home before i could fix it, any chance this may have done something?
cheers

Check that your fuel filter is not partially blocked.

Carby jets clean? [if you ran the tank dry you have probably picked up some of the crap that normally sits in the bottom of the tank]

Also when did you last clean/replace the spark plugs?

Start checking the "easy" stuff first.

Things like rectifiers and other less likely stuff comes after you have checked the basics.

Mechanics always try to "fix" the expensive stuff first, then keep you coming back with more money while they continue to drain your wallet in search of the problem.

Find an "old school" mechanic who runs a workshop that works on all brands and ages of bikes, they are the ones who know their stuff and won't rip you off.

hey, thanks for the advice! I had a breif look! and to be honest probably caused more harm!! A couple of things to ask though!

Whats the easiest wasy to check the jets?

If some crap went down the spark plug hole whats the best course of action? it didnt look like alot of crap but not sure what went in (told you i probably made it worse!)

the spark plugs are the originals tho I have only had the bike less than a year but she is 6 years old so probably due a change anyway

Im used to doing a fair bit of work on diesel engines, this is my first experience of a petrol, so im not quite sure!

Just thought i'd throw in a pic!
