New engine turned up today….woohoo!! The joy was short lived though because of the shock discovery of a mangled exhaust outlet, chipped surrounding fins and butchered exhaust stud. Leaving me only around 7mm of thread to play with! Subsequently it has now had to go to the doctor to have an extraction done with the correct tools for the job. Fingers crossed it comes out cleanly.
Down to business though. Apart from the above problem the engine looks pretty good, and turns over with no nasty noises etc. Haven’t checked the clearances yet, but I will when she comes home. One thing that jumped out straight away is the presence of a pipe (i assume to be vacuum) coming out of the rear cylinder.
On my old engine this pipe is not present and the port is blanked off.
I have checked through both the workshop manuals and the parts catalogues and come up with nothing. It doesn’t even appear as part of the engine rebuild process in the workshop manual, and I don’t see it listed anywhere in the parts catalogue.
Can anyone tell me what this pipe is for and where it should go? Also, as my original engine is blanked, is it just a case of getting a blanking plate and gasket for the port? Where would I get such a thing?
Please excuse my ignorance if this is a total newbie question, but as I mentioned in my intro I am completely new to bikes, so this one is a bit of a mystery. All I can think is that it could be to run a fuel pump or the like.
Thanks in advance.
