The major overhaul is coming along fine. Valve clearances are done, new belts fitted, lots of small faults and damaged bits fixed and wiring loom ripped to bits and put back together with decently dimensioned wires and earths. Next thing I'm going to do do is wire in relays to the lights. This will cut the losses to them so they are brighter and have the side effect of unloading the wiring.
While the thing was coming apart I noticed that he inlet ports were the nicest I have ever seen on any production bike, looks like they have been finished with a flapper wheel. Me and a couple of mates stood admiring them and wondering if somebody has had work done on them. We already knew the EPROM wasn't standard and that the exhaust may be a bit special (you can see straight down inside it and it has an absorbtion type silencer. If it is a cored job then it is a VERY good one). A contact has suggested they may be from a 748R
Tonight I was looking over the pump and filter assembly and noticed the pressure regulator was dished in as though it had been squeezed to icrease the fuel pressure. I had a quick look at the 900SS engine I have ready to on the bench and it looks like somebody has given the pressure regulator on this a bash with a hammer and socket to do the same thing, Something I hadn't notice and probably explains the black plug this engine came with.
I am now begining to wonder if the 748 motor has been played with, possibly by somebody who new what they were doing. Now I have to make up a rig to test at what pressure the regulator opens at. This should be interesting. Interestingly all the suspension settings are absolutely standard - on a 1995 bike. It looks like nothing has ever been adjusted.
At this rate it should be ridabled around mid january. I'm looking forward to finding out what it goes like. When I rode it home it went straight into the garage. It went well enough low down but was unwilling to rev. This was probaly due to rotten fuel and a dirty air filter though.
