I am constantly messing with the throttle stop adjuster screw. It doesn't matter which way I turn it, it makes no difference. I must have cleaned the carb out a dozen times. I have replaced the needle valve assembly and washer. I have also made sure the little hole in the float bowl is clear. What else can I check?

But it's a brand new crank seal. I think my friend has a CDI I could try. I will do anything to get it running right. Can't sit at traffic lights with no tickover!
-
Airhead - Ta very much my friend - you Sussed it! It was a hard piece of that wax stuff protruding from the bottom of one of the coils. I simple removed it with a ladies wooden nail file and the noise has gone!
It's actually running a little better too. No problems from zero revs right up to 4500 grand. It hesitates between 4500-5000 grand and then she's off again. I am ok with this. I am more bothered about the fact she won't tickover. Is the low speed coil knackered? Like I said before I am ok with mechanicals - totally crap with electrics.

Magnet all are tight. I just gave them all a wiggle per your suggestion. I will very carefully dress the iron coil in question.
I nearly forgot to tell you the bike idled for a minute when I started it without the crankcase cover.

Spit the tipex on the magnet and where it's worn off of the coil

I took a video of it running with the crankcase off. Is it possible to post it here?
-
Ok I just put it back together and fired it up without the crankcase on. Problem is still there - You can only hear the noise each time the motor cycles down after reving it. I pulled the mag an noticed the tipex had slightly worn off of one of the coil bottoms and one small area on one of the magnets on the magneto. This half of the magnet and the one next to it are much more worn than the other magnets. Any idea what could be causing this to happen?

Been ere thekteen years but still a Morley lad threw and threw lol.

Flywheel has been removed. Used the kicker to test on all four angles - I found zero play.
The climate down here is right for bikes. If you ever need anything let me know. I have shipped many a bike and bits back home. Glad to help anyone out.
fettling with it as we speak.

I must have been hallucinating yesterday....just tried the shaft again and their is zero okay up and down. The bike has had a very easy life and it only has 3,000 miles on the speedo. I am going to put it back together right now. I will reply shortly. Thanks for the help and advice. I love this little bike, I just want to get it running right!

Thanks for the tip on posting photos. I like your tipex suggestion. Going to give it a try. I have never noticed any oil coming from the mag side oil seal. It is dry as a bone. Going to mess with it again now.
-
I do not know how to attach pictures to a post? Their is a groove in one of the magnets and burring on the edge of the source coils. I am not sure how it got there? Their is no up and down or side to side movement when you grab hold of the magneto. If you remove the magneto and grab hold of the shaft you can feel the tiniest bit of up and down movement and Zero side to side lateral movement.

Just to let you know I bought the DT from the original owner. I dont think a spanner ever touched it before I bought it. It had been sat since 1982.

I just posted a load of Flickr links off my mag and stator. I did notice some where on the magnets on the inside of the mag (see pics). The ends of the coils are also worn in places (see pics). Everything was still tight when I removed the side case. How does it look?

I did not notice any lateral play in the magneto rotor and yes the magneto was torqued down correctly to 39.5 ft. lbs. with a very good quality torque wrench. I better whip the casing off and have another look. I will let you know what I find out. Thanks

Sorry about that Airhead - My pipe does have the restrictor in it.
I am not very good with electrics - which coil should I be concerned about and how do I test it? (I only have a very simple cen-tec seven function digital multimeter).
One other thing I noticed before and now after I replaced the crank seal is a whining or whuring noise coming from inside the stator crank case cover. I can only hear it when the bike is cold. It disappears after around 30-60 seconds.
-
Well I have changed the stator side crank seal and O-ring that's seats the carb main jet. I have also cleaned out the exhaust pipe (it was pretty clean to be honest as the bike has only done 3,000 miles from new). Last job was to check the carb rubber - no leaks their. My bike is running a little better in the low rpm stages but it still hesitates right around 5000 rpm (its all good after 5000 rpm). I am still unable to get it to tick over. Should I go ahead and look at buying a used stator or do any of you fella have any other ideas?
Thanks
