Airhead

Try to eliminate the ignition switch as the culprit. is there a brown wire on the flasher relay? as a temporary measure unplug this and connect the relay direct to batt+

But how do you know you bought the right size one? Have you still got the old one?

Eee when i were a lad we used to wrap em round the fork leg Ha!

Doesnt the XT and YBR share the same workshop manual (Haynes)

Greetings john, the little XT is looking great does the arrow exhaust improve performance, I guess it does they're not cheap Oh I've had no less than 2 bikes since 1982

Greetings bob try WD40 on the ignition coil, my DTMX is getting a bit iffy in the wet too!

Greetings Andy and so how is the old RD? got much to do?

a few questions... Why did you replace the piston? What size was the old one, What size is the new one? I suggest a compression test can you do one?

yeah John they're everywhere

He's piston the floor merv

so you've had the barrel off, perhaps you have unfortunately left a torn piece of the original cylinder base gasket trapped under the new one?

Code 402 is for 1973 DT125A(B ) ? you will normally see the engine displacement shown in the casting at the base of the cylinder

yeah mitaka are good japanese quality Ken http://www.pjme.co.uk/

Whaahahahaaa :lol:

Thats just great I'll pass on doing it to the old DT though

Ive seen the terms divvy and pre-divvy banded about, myself I havent got a clue lol, perhaps try bikepics site?

Great stuff Stu, where in Manchester are you?

You're gonna struggle, try ringing Fowlers of Bristol

at a guess it will be posn 2 on the key for lights and the headlight may need the engine running, not 100% sure maybe posn 3 you can withdraw the key? and this could be a parking light... its not a DT175E though

Yeah thats a new on one me, so whats the trick then? Looks great

to shine it up mate

the brake light runs from the battery The headlight is totally seperate and is directly powered from the magneto...so needs the key in position 2 possibly and the engine running and switches on. how many positions does your key switch have including OFF ? is it OFF, 1, 2, 3 ? on the left hand control is there an On / Off for lights ?

Looks like Haynes do a service manual, dunno if theres a parts manual yet http://www.haynes.com/products/productID/595

It's near Sherburn in Elmet, not too far from Leeds, a very popular biker cafe / bar

No problem with 4 bangers bippo, the more the merrier...ever been to squires?
