Airhead

dunna worry about it John, I can find it on my frame and motor

it had matching numbers when new jack

It's a satnav not a bloody toaster! I never heard so much nonsense, fit the satnav you wont have any problem. i run a satnav on an old DT175 with 6v electrics without any problem at all. People even run heated grips on them, now that may arguably be not recommended but ya pays yer money and takes ya chance with that one!

Phew, now thats great news Moe...yep you learned a lot with this one. Well done, hope you still have a comb-over at least

Yep Bk/Wh is the colour for the source coil, photos would have helped y'know

Yep thats very nice indeed mate Greetings

maybe you can check with a multimeter to see if any of the socket terminals come up 'live' with the negative lead on the negative battery terminal? I assume it's an lcd display thats totally blank

Greetings jbk, dont see many YBR 250s can you post up a pic? Sounds just the job for getting around the beautiful dales

is it loose on the spline grouch?

Greetings Ben

I got my info from a DT125E parts catalog, though for some strange reason the service data pertaiined to DT100? ...misprint? I dont have any info on voltage, neither do I have a bike with points, my source coil generates around 130v to a CDI unit and measures hundreds of ohms...lots more turns than yours of couse you see a varying resistance as the points open and close...think about it! closed you are measuring a dead short through the points...open you are measuring coil resistance I dont recall you saying that you tested the HT coil and that is within specification ?

I out of ideas if you still dont have a spark! the figure I saw for the source coil was 1.7 ohms It seems to me that you meter reads 0.6 ohms when you touch the probes together, same as when the points are closed. so if this is the case 2.7 - 0.6 = 2.1 ..slightly over the 1.7 +- 10% but not much

yes it matters

Greetings marshmallow Nice intro mon ami

could you be connected the wrong way round on the source coil?

this is your first post on here so how? "I have posed this a few times on here and keep getting stupid replys but owell iltry again"

it will clean oil/grease well, wear gloves and goggles of course. It is not as volatile as petrol

Check the filter screens, theres no doubt one on the petcock (may be inside the tank)...There may also be one in the carb (may be in the float needle valve) It may also be as blackhat said, thats an easy find...just spray WD40 around the intake when it's idling too fast...see if there's a change

How about paraffin (kerosene) ?

I went to Matlock, v busy as usual

do you get access to it then dave?

Its coming on mate, not the easiest restore to try and tackle eh?

Onwatds and upward Matthew, that XJR looks great for the money

Greetings tez, Bandit? ancient out of date? ...Pahhhh

of course the pistons are skimmed to size using a lathe, the marks you see are just carbon deposits in the grooves left by the machining process
