    I think I just answered my own question. Check this out

    Those notches are like the shift star.

    This part that Blood refered to as the Tranny wiener must ride in those and give you the "detent" feeling as you shift

    Now Im going to have to locate that part as I dont remember seeing it as I took the tranny out. Hopefully its still in the case otherwise its in the bottom of the parts washer. I hope.

    If ya havent figured out by now I like knowing how things work. Im an engineer by trade so understanding how things work, even if its just a basic understanding is kinda etched into my programing.

    Yea cuz he is going to have to start picking up the slack from me because my progress is about to come to a screeching hault as the next step for me involves an infusion of around $300 that I dont have.

    I have to buy a set of pistons, have the crank ballanced, and buy a cam. Pistons run around $100. Crank Ballancing should be around $100 (Im converting from a 500cc to a 650cc so the crank needs to be re-ballanced for the heavier 650 pistons). My guy has a used 650 cam that I think I can get for around $35 (500 and 650 cams are diff). I am hoping all my bearings are still good otherwise that will cost me more $$. hes going to check that all out when he gets the crank. Oh and I need a sludge trap allen head plug also.

    So Im guessing that is going to cost me at least $300. Then I can put the crank back in with fresh seals that I have and button the bottom end back up.

    Then the next step is to get the cylinders bored for the oversized pistons, around $50. Oh and I need some 650 pushrods thats another $20. Once I have that I can button up the top end. That is, assuming my head is good. I havent even looked at that. I still need to tear the head apart, have the head and cylinder media blasted and panted. Then put the head back together. Hopefully I can get away with just a valve lapping and new valve seals and be done with it. But we will see.

    Then comes the clutch plates and drive chain. Probably around $150.

    Then comes the ignition. I dont even know where I am going with that other than its going to be Boyer. I have some research to do on that one. I think the ignition goes for like $150-175. I can use my stock coils and I think stock alternator. And I might be able to eliminate the battery to boot. well see. I have a lot to learn about all that yet. Thats waaaay down the road. Lots of $ has to be spent before I get anywhere near that.



    So I guess its time to start ebaying off lots of stuff I have laying around to try and rummage up some spare jingle. I have spare cash. But if it comes to spending the weekend in the woods on the dirtbike or in the garage with the BSA....sorry fellas...the woods calls to me. It will snow eventually and Ill be back in the garage with spare funds to play with :D

    My '69 Lightning is pretty much on hold until a new wiring harness makes it's way from England sometime next month. I put new tires on it,and I've been polishing a bit,but the pace of my restoration can best be described as "leisurely"

    I'm still alive ! It has been a dark and busy few months. I'm almost out - last week of classes, finals next week. I think I might make it :1drink

    I did have some time here and there, not a lot of work on the bsa - but my goose got worked over pretty good. Time was so tight though, couldn't snap even one pic. Just got back from a ~400mi trip this weekend and she's singing stronger than ever.


    YZMAN - i've got an allen sludge trap plug for you. PM me your addy :deal

    Ive been wanting a vintage project for a loong time. This one kinda just fell in my lap and I kinda fell for it.

    Got an email from my BSA guru ED at EV Engineering. He said that the oil pump pickup tube is just pressed in the case. A little heat on the case and it will slide right out. he has a used one around there that I can have/buy.

    He also has a cast aluminum finned oil sump cover with a magnetic drain plug for sale...Hmmmm that sounds nice! :D

    Going to see him this weekend for the 1st time. Well see how bad a beating my Visa takes when I get back.

    The bike looks neat. I have a 67 441 single that I'm doing as a cafe racer.
    You might want to check out www.britgaskets.ca. The fellows name is Steve Dales and his only transportation is a 69 441.

    So today I took the day of from work (mental health day)

    I loaded up the Vstrom with BSA parts and hit the back roads. My destination, EV Engineering, an hour away. Never been there before but have contacted them a few times.

    THIS PLACE IS COOL.

    Its a pole barn. Inside is decades of history. Parts and pieces and fenders and tanks and this and that and and and... Piles of history laying everywhere. Paths thru the rubble leading to his various machines and work benches. Has that old motorcycle funk to it. Way cool place.

    ED the owner is exactly what I expected. Maybe in his 50's. Big gray bushy beard.

    We wandered out to my bike to see what I had to work with. Without even looking at a book he measured my cylinder, crank and knew exactly what they were supposed to measure at. That was impressive.


    So the verdict so far.

    Needs a new lh main bearing $80
    New rod bearings $50
    Crank may need to to be turned for the rod bearings but that remains to be seen.
    Crank ballanced for 650 pistons $100
    New .060 over pistons $100
    New oil pump pickup tube
    New oil sump cover plate $10
    used 650 cam $30
    Pushrods $15

    So it looks like under $500 will button the bottom back up. Said it might be done some time around July :eek1 Seriously! :lol3 Hes pretty busy and a one man show.


    Hey Blood. Did you measure your rh crank bushing and crank end? Ed said that if its not tight enough you wont get any oil pressure to the rods. Said mine had about 2 and a half thousands clearance I think, and that is on the loose side. 2 thou would of been better but he thinks I will be fine. He said that bushing is responsible for the oil pressure to the rods. If thats loose oil will leak out from around the bushing and you wont get oil to the rods.


    Also Blood where did you get your crank shims? ED dosn't sell a kit per say. It sounds like it should be easy enough to shim the crank. But I need the shims to do it. I could just by a random selection of shims from ED but at an hour away thats a bit of a treck for a shim should I need a diff size that I dont have.

    So thats about it for now.

    I did get the valves out of the head last night. Everything looks pretty good. Hopefully I can get the head and cylinder in to get them blasted soon. Im thinking the valve guides should come out also before I get it blasted. How do they come out? just tap them out?

    Spent the morning reading about Boyer ignition systems, coils, and wireing diagrams...I think my brain is turning to mush :D

    To be honest the wireing (or lack of) on this bike scares the crap out of me. I would rather pull 10 sludge traps out than tackle the ignition system on this bastard :rofl

    Progress. A little anyways.

    While I am waiting for my crank to come back

    I spent a few hours getting friendly with the gas tank.

    You remember that tank.

    Well I picked up some supplies and dove into it today.

    [​IMG]

    Masked off the shiny parts

    [​IMG]

    And attacked it with the paint stripper

    [​IMG]

    The end result turned out pretty good I think

    Next question would be. What should I do about the tunnel of the tank. It has a little surface rust on it where the rubber cushons sit.

    Im thinking just some rust preventing primer and paint the tunnel black. Id like to just leave it as is as I kinda like the chrome tunnel but I have to do something about that rust. Maybe just sand down those 2 spots. Mask it all off and just pant those 2 areas.

    You could always just remove the rust and spray it with clear.

    Or do it properly and strip and re-chrome :yikes
    I spent ages, years ago trying to save a BSA C15 tank with the chrome panels.
    Ended up doing it properly, cost at the time was very reasonable as I remember.
    It's not like it's hard work, just choose a plater who you trust to do the work well.

    Quick update:

    I just emailed my BSA mechanic guy that is working on my crank. He has had my crank and cases all summer. While he is very good he is a one man show and aparently very slow. But I rattled his cage and he is going to start on mine next. Basicaly told him to shit or get off the pot... Im tired of waiting.

    So hopefully in the next few weeks the updates should start to flow again as I re-assemble the lower end and press on from there.
