While I haven’t done a whole lot on the bike lately, neither have I left it completely untouched.
Today, I received my borescope, purchased on eBay. At this point, I haven’t worked out a good way to photograph through it.
Before the scope arrived, I borrowed a Rigid See Snake. This is basically a tiny camera with lights at the end of a three foot gooseneck, with a color monitor in the pistol grip. The camera module is about 3/4″ in diameter, so it wont through as small a hole as the borescope, but it’s way easier to share the vision.
The duct between the compressor and the surge tank is steel, presumably to withstand boost pressure better than the more typical neoprene. Peering into the duct, I saw bright surface rust, which worries me because I now must presume that the turbocharger has been exposed to raw weather.
This is the pile of what I am guessing to be cypress leaves and lots of other trash that is sitting at the bottom of the duct between the compressor and the airbox or surge tank on the Seca. The round boundary at the edges of the pic is the bottom end of the duct, where the body of the duct and the coupler meet. The wide ring most visible in the lower right is the outlet duct of the compressor itself.
Without checking this first (and for the record, I was planning to pull the ducts and even the turbocharger out and check it anyway) this trash would have been blown up into the surge tank and on into the cylinders where it may or may not have caused any appreciable damage.
None of the pix came out good, but the other duct, between the airbox and the inlet of the compressor, has a substantial amount of standing oil in it, at the elbow where it turns towards the compressor.
