MC18 Oil Pump Hoses to Carb

Thu Jan 02, 2014 6:17 am » Post: #1 » Download Post

Hey guys,

I realise this might be a silly question, but I am not sure where the two hoses from the oil pump go to on the carb bodies. I have had a look around the forums and workshop section but to no avail. Apologies, but this is an issue with trying to put something back together from 1,000 pieces.

I have cleaned the carbies and run the old jigger on premix with good result, but i now want make it more streetable. I have taken some piccies so if someone could point me in the right direction it would be greatly appreciated.









Cheers

Look at the first photo... now remove the "loop" between the two oil feed unions, and connect the injector hoses there.

Then refer to this page for stock carb settings, and this page for "guideline" jet settings for derestricted bikes.

Please note, there can be no specific jetting discussion in the public forums. There is a section for jetting in the Titanium Members section only.

Posts discussing specific jetting other than stock sizes are liable to be deleted without warning.

That's great. thanks Andy!

I suspected that might be the case and that the previous owner was running premix but I didn't want to gamble seizure on it.

Cheers
