Looks like the sending wire for the oil pressure switch. If you are replacing it only because of the rubber boot, I wouldn't bother. The rubber boot is only there as a cosmetic cover up to conceal the ring terminal. I have to cut mine off and I will leave it bare. Just brush a bit of liquid tape over the ring terminal.
Liquid Tape
The rubber boot will only cause problems in a damp environment by holding moisture in.
to have him fit the cylinders back on as well because sometimes they can bind up and if you have no experience with it, it could become problematic.
MikenVA has a point there. Being a twin engine, you are trying to fit two pistons at the same time. It could be problematic. A broken ring could be a possibility. Easy to fix but if you don't catch it, big problems.
Gonna throw you another curve ball here. Your Neutral Position Switch lives under your transmission. Is that where the oil leak came from? If it got too hot, did it seperate internally and leak oil? Possibly?
Just a thought. I know mine leaks but not enough to really worry about it. I do have a couple oil spots where the bike parks. One is from the sprocket cover (too much chain oil) and the other is from the neutral switch.
That is an awesome piece of info King! ThanksJim Hamlin/Hamlin Cycles LLC. He was the tech at Branchville before they folded. Now has his own shop.
You are correct - at the end there was a pool of oil (about a cup full) below the bike. Where it came from I'm just not sure. Thats when I decided to have the dealership find it for me and the rest we all know!Okay. I thought I read in one of your previous posts that when this all started, you had a pool of oil under the bike.
Oh wait. Cam cover gasket? If so, no worry now as you are putting new gaskets in anyhow.
good luck man sounds like you will do fine
Thanks Roger - your were instrumental in coaching me!That's quite the list of parts and gaskets. At least you are on your way to getting the engine back together. An undesired mishap but you have gained some good knowledge from it. I have known a few people that wouldn't venture this far into a repair. Scary as it was, you still managed to get it to this point. Now, if this was a BMW S1000RR, that would have been a whole different ball game. The simplicity of the twin engines makes them so much easier to work on. These engines are in fact simpler to work on than the original vintage Bonnevilles.
If you want some insight into what the old bikes are like, there is a guy named John in the UK. He has a whole slew of videos on Youtube. Google lunmad. I really like his engine rebuild vids and his ride vids. You thought this engine would be difficult? Have a look at his rebuild vids when you get a chance. Those old bikes require a whole different set of rules. But when all is said and done, it is all mechanical ability.
Glad you are on your way to wrapping this up. Well before spring kicks in too.
I havent seen him since a bunch of us got together at Carlisle PA for a motorcycle swap meet about 5-6 years ago.
I remember that trip!
