    Engine teardown

    Hey Stew,

    I'll be doing the hydra blasting thing. Gonna take it all apart.

    Meet my engine builder Tory.

    I bumped into him about a year & a half ago when I saw his SR parked outside my fastener place. He's been helpful with many things
    & has upped my SR knowledge. He's got quite the collection of bikes. They include Triumph, Harley, Honda & Yamaha of course. There's a
    couple XT's & SR's. When I was over today he had an XT engine on his bench that he was doing the top end on. He completed a build about a year ago. Here's an article about him.

    My knowledge of the inside workings of the SR engine is limited so I'll be trusting him to guide me through the process.
    I dropped the engine off today. Engine build on.
    Tory dug into things right away. He had things apart in a matter minutes. Exhaust valve will need some attention.

    Cam chain needs replacing. Here you can see the top of the spark plug. The tip is bent from me trying to remove it with an extractor. No budge.
    We'll see what Tory comes up with & find out more as we go.

    Ah, good stuff. So long as he does it all properly then you're away.

    I've had guys ask me to do engines but I generally shy away unless it's to stock specs...then not so bad.

    If they want HC Pistons etc. then although I do my own and a couple of others, like a mate and my Brother, I won't do them. Too much scope for things to go wrong.

    Look forward to seeing things as they go along.

    Hey Stew,

    Tory has recommended a 10:1 piston & that's about it. He has a bunch of friends that race SR's & XT's & the feedback is go all out or
    leave it more or less stock. Lots of money can be spent for small gains.

    Yes I'd tend to agree...plus new one piece valves, decent carby matched to manifold and port, good free'er flowing pipe and any thing else that takes your fancy.

    For a little further, mild mid range cam, porting job to match...

    There is a fair bit you can do to them...but the further you go more diminishing returns as you say.

    My Salt Racer engine has been a bit of an evolving process...stopped now.

    Electrical

    While Tory is working on my engine I figured it's time to start getting the wiring sorted out. it'll be more or less a plug & play thing for me.
    I shouldn't need to dig into the harness much for my needs. That being said I bought a new one from Rex's.

    First thing at hand is making a tray for the electrics & battery. I had a chunk of chloroplast kicking around so I started sorting out a shape.

    I ended up with this.

    I had planned on using this location as a mounting point but it was getting in the way so I cut it off.

    There's room for things but I'll play with the routing of wires & connectors before I start on the aluminium.
    I plan on mounting the regulator under the tray for airflow.

    I've chosen a Shorai battery. It comes recommended & has good specs. I'll also be ordering a new CDI & regulator from Rex's.

    More wires

    I threaded my new harness into place. It's handy having the Eggplant around for reference.
    The wires were intertwined more than to my liking.

    I had to release a number of the wires from the conectors to sort things out.

    When I threaded my switch wires through the bars I had to cut off 3 of the connectors.

    My plan was to redo the pins & install into the connector but I haven't had any luck finding these round style ones from any of the suppliers.
    These are the ones I'm looking for.

    If anyone knows where I can get them I'd appreciate some info. If I can't source them I'll just use bullet connectors or multi pin spade style.
    Anyway all I need to do is connect this pile of spaghetti to this one.

    Marcus should be able to sort some out for you?

    Given the rest of the neat & clean mechanical work you have done it is my opinion you should greatly abbreviate that harness into the more spartan version.

    Thanks Stew.

    gcrank, Yup I've been pondering that. I'm not the fastest at this so I was hoping to save some time by using something already made. Maybe I'll troll around on the old site & see what's involved.
    It would be nice to get rid of all the redundant wires. Have you done it?

    I havent done it to this bike but have in the past. There are yards of 'extra' wires.....You break it down to systems; ie, charging sys, ig sys, lighting sys, etc and abbreviate the runs. Getting rid of the wiring that runs to the headlight bucket to just plug in and run rearward again will clean up a lot.
    I like to start with simple runs; say, the tail/brake wiring, the alt to the reg/rec unit, the bar switchgear, etc., that warms me up to the more complicated stuff. I strip wires out of a loom and use the same color coding as oem if possible (at first, it will help you to dbl check what you are 'connecting'). Too long wires I wrap back on themselves and elec tape wrap to shorter without cutting, at least at first. Once you get a feel for it you may find a 'wrong color wire' has the the ends and length you would like to use, so use it. You will probably need to make up your own finalized wiring schematic anyway.
    It takes on a life of its own as you get your head wrapped around the process, then moves along in an orderly, logical fashion. And when you are done you will be SO glad you did it NOW.
