Moderator Airhead Posted June 21, 2013 Moderator Posted June 21, 2013 OK so over last couple of months, Ive been dong some WOT plug chops to try to achieve the holy grail of a coffee colour at my sparkplug, I suppose since I fitted the temperature gauge I've been a bit paranoid about the temperature this engine runs at! so what do you guys think of this then Rich, Right, Lean ???
NE0 Posted June 21, 2013 Posted June 21, 2013 Assuming its done a few miles I think it looks right. Not checked mine to compare it!
blackhat250 Posted June 21, 2013 Posted June 21, 2013 Acording to Stan [ stephens] the man,, its not the earth strap [ tip] that the colour is , its the threaded area, and yours looks Blackish,, rich then,,, also he says W.O.throttle, but not full revs, if you know wot he means,,
busyeddie Posted June 21, 2013 Posted June 21, 2013 I was reading somethin about dt175 mx's tother day regarding the spark plug position. Apparently its not best suited to new fuels. Explains why I have melted a couple of pistons recently. They reckon an it175 head is the way to go, with its.centrally positioned spark plug. Might be some mileage in it. I dont know.
Moderator Airhead Posted June 21, 2013 Author Moderator Posted June 21, 2013 I read the same thing just tonight eddie, frankly I dont believe it's correct though whatever their conclusion was!...or we'd all be having the same problem wouldnt we? so then...what do you think of this sparkplug?

busyeddie Posted June 22, 2013 Posted June 22, 2013 I did think there would be a pandemic of blown DT engines if really was that bad. Yours looks ok to me Paul. But hey what do I know, mine's often looked similar and then left me stranded on the dual carriageway twice! I bought a dial gauge not so long ago from yambits but its about as useful as a chocolate chip pan. The extensions are either too short or too long.

Eddie get an old bicycle spoke...you may find the thread is the same as on your dial gauge....then just cut it to length. Thats what I did when faced with the same problem.
busyeddie Posted June 23, 2013 Posted June 23, 2013 Aahh good idea Paul. However the gauge itself is now gubbed! Basically I turned the motor over with a too long proddy bit and now it's.propr done in. Im not a hapless teenager. Honest.
Moderator DirtyDT Posted June 24, 2013 Moderator Posted June 24, 2013 Looks about spot on to me. I wouldn't want to lean that up anymore and would take into account the quality of the 2 stroke oils now compared to when these bikes were built.
Moderator Airhead Posted June 24, 2013 Author Moderator Posted June 24, 2013 OK so thats a couple of just rights and a rich anyone else want to offer an opinion ? I've got more to say about this in due course
Moderator Airhead Posted June 24, 2013 Author Moderator Posted June 24, 2013 Haha Paul, was that aimed at me? no mate i'm waiting for Cynic's opinion now
Ventura Posted June 24, 2013 Posted June 24, 2013 I have a feeling that Paul is leading us on before making a grand declaration as to how he knows the answer!! I'd say your plug is exactly spot-on!! V.
flyday58 Posted June 24, 2013 Posted June 24, 2013 I'll throw in for a bit on the lean side with today's ethanol-diluted crap. Seems there should be at least a hint of blush to the ceramic. FWIW.
Moderator DirtyDT Posted June 24, 2013 Moderator Posted June 24, 2013 I hope it's not because my plug is about the same. Mind you he may have had at least the head off, according to another thread, so I hope that the bike is OK!
blackhat250 Posted June 24, 2013 Posted June 24, 2013 Wheres that bloody Cynic " i want the conclusion, has he run out of oil AGAIN,,,, 1
Moderator DirtyDT Posted June 25, 2013 Moderator Posted June 25, 2013 Airhead IS the master of suspense!
