Yamaha dt125re rebuild

@bradt best way is to run premix in your bike while running with the autolube full bleed the lines there will be a rubber blanking cap on the pump pull that off While the bike is running on premix and when the air bubbles stop coming out plug it back up then watch the flow coming from the pump to engine best use clear lines so you can see the air bubbles then when there’s no bubbles your good to switch back to autolube fully

Cheers mate ordered some clear lines
Bike all ready now, but have noticed a leak from the carb guessing bowl gasket needs replacing
Auto lube needs bleeding also and she ready for her first start
First time out the garage in a few months quick wipe down and a polish

Does anyone know where the black wire (I’m guess an earth) on the coil is meant to go
Iv just fitted a new startermotor to the build makes it easier to start and found I have no coil
Noticed the black wire with hook was connected to the coil itself should this be earthed to frame or is this right ?
-
The starter motor has a red wire only which connects to the starter solenoid (this is the square thing with two fuses in it by the battery). There is a black wire with a hook which connects to the neutral switch which is located near to the starter motor at the bottom of the engine casing on the flywheel side. this in turn plugs into the part of the loom which goes into the stator/generator coil via a bullet connector. Hope this helps.

@2Stroke4Smoke very helpful went through all wire and found a broken wire replaced and fixed nice bright sparks and fired up
Thank you

So last night after during the match I decided to take the bike for a ride out see how everything was , bike felt great really responsive but loud but exhaust needs sorting
Come out for work this morning bike fired up felt great work is only 5mile away iv got just round the corner and my red light came on and the bike was steaming pretty bad I coasted it to work and iv lost all my coolant I’m aware this could be down to the head gasket but I’m hoping it may be something else.
There was pressure in the radiator when I took the cap off and the expansion bottle cap has stayed on any one know what else to check before I order a head gasket ?
Thanks

@declan surely any liquid would dry and leave some kind of substance after touching a hot engine. Iv reckon iv found the culprit there a little house what connect to carbs what isn’t fully on and can see it coming from there but the amount iv lost surely hasn’t come from there I’m unsure tired and frustrated and still gotta rude home on it tonight after work!

So iv got back and did a little test on the way,
So when I’m cruising (not full throttle) the bike fine doesn’t smoke out the exhaust and no steam off the engine, so on a little open bit of road iv throttled the bike started slowing down and there u go smoke and steam
So seams to me when the pv kicks in I’m loosing coolant any ideas ??
any local to Sheffield and wanna source a spare bowl gasket ?
