It Lives

    Well it lives, and with out finding what or where that annoying little O ring was or came from.
    Fired right up no issues, no long cracking and no stumbling coughing or farting.
     
    Thanks to all the help with my sometimes what may have seemed stupid questions over the last month or so.
    Been some very helpful guys on here thanks for your help and paitence.
     
    Got a fair way to go with tuning some of the very annoying habits out of it, but it all seems to be ok.
    No leaks and no strange noises. A bit rattly but I think that is in the valve train, may quieten down with pushrod adjustment or may not.
    CCP is a lot lower then I expected but may come up hopefully with a few more K's on it or my tester might not be any good. It absolutely needs the compression releases pushed to start it.
     
    Did 4 progressive heat cycles then out for my usual running in process. Still no leaks so out for a longer run in the back blocks with some hills.
    Does seem to go OK but nothing startling.
    A few auto tune runs next week then hopefully I can get it on the dyno for a proper tune.

    Good news Ozymax
    What was the CCP you expected and what came up. The motor will loosern up and get better and better as you clock the K's up.
    Get a few Vtunes done ASAP.

    The calculator says it should go 205 ccp but it's no where near that, 190 front and back so at least they are the same. 270kms
    think it's got a few issues which could be my lack of engine building experience in the last 15 years, maybe the old practices don't apply to the modern harley motor.
    Main concern for me is I vented it to ground and I can see the fuming at idle, doesn't drop any oil but definitely color changes the transmission cases
    done a few auto tunes and it does run better, will get on the dyno next week but haven't got much enthusiasm for it now

    yea cold mate and not a lot of confidence in the gauge.
    will get it checked and do a leak down next week before going on the dyno with some descent gauges
    more thinking about the breather issues than ccp

    I guess if I hadn't of vented it to ground I would never have seen it or smelt it and so would not have thought about it.

    CCP IS little higher when not stone cold but still only 190, the calculator suggests 205.
    any way tune it on the dyno next week, checked the plugs today and it looks lean to me.
    just wait and see what happens next week.

    It took me three builds to get my CCP where I wanted it 10.1. The second build I brought cometic 30 head gaskets and fitted them without running the verniers over them. I found out on the third build after measuring everything on mk2 build  trying to work out what went wrong. The supposedly 30 turned out to be 45 I was pissed but it was my fault for not checking just assuming they where the 30's.

    I did check every thing mate, measured and measured again.
    Checked chamber volumes before and after milling, valve dish volume, piston valve relief volume, deck height, ring gaps, HG thickness, valve to piston and valve to valve clearances, about the only thing I didn't check was crank run out as I just couldn't get the dial indicator in the correct position. I even checked run out and travel on the bandit clutch, I adjusted everything to what I thought I needed to get it right.
    About the only thing I didn't check was the cams for degree and after it was all buttoned up I thought fuck I should have degree'd the cams not just set the dot to dot.
    Bought new Mic's, verniers and dials since most of my stuff had been in the tool box for many many years and I wanted to be as close as I could get it.

    Static CP I am confident is 10.8:1 but I do not know how to calculate the CCP so I trusted that the online calculators are close. That said how accurate all their inputs are is any one's guess. At some point it comes down to a person keying in info and I don't really know how much difference the number would make.

    I don't think it is cammed over the top but am willing to listen

    that was the plan. all balls down low up to maybe 4500, I dont really ride it past that. Do a lot of 2 up slow mountain stuff. If I need to ring the tits of it to enjoy it I'll get something different

    well my ass dyno is in need of education.
    ran it up today and to the nearest whole numbers 122 122 which is a lot better than I thought. tuning picked up about 4 ft lb and6hp so the tune wasn't to bad to start out.

    yes mate it is great I can easily be a gear higher than before and the new 30 th front and 68 rear will make it really good, 6th will be 100kph no problem, just like a real 6 speed

    Agree mate when and where it it does it just were I planned it to be.
    Really surprised me that it came out so well.
    Did have one issue to resolve, the front header pipe cracked and I had to pull it off and go get it welded before we could start tuning.
    Fred made a call to get it done, lent me his gear to take it off and put it back on, gave me the shop van to go get it welded. Couldn't ask for a better out come than that.
    this is his set up
    Dynojet Model 250 Load-Control Dynamometer and the Dynojet realtime Air/Fuel Ratio module, along with an equal pressure air controlled sound proof room to simulate real time conditions.

    30t is stock harley trike part $90
    68t rear is stock harley part don't remember but think $220
    standard is 32 66 no belt change needed for me no idea what tooth count I have
    there is some guide about 6mm per tooth but don't quote me on it

    std and smoothing 4, which gives a lower HP reading,,,,, correct?
    I think he was doing the power pulls in 6 but I wasn't always in the booth.


    regardless of the graph it's about how it rides to me and it rides good

    yes I have spent a bit of time there with him and the boys over the last year and seen some very impressive street bikes come off the roller. I think mine was the weakest on the day but then again I don't have any forced induction or spray.
    But it's still nice to see what can be done. The thing I like is when he is done he then rides the bike to see if it feels right. Had a few tuned there and never had to take one back.

    yes mate very well organized out fit. a lot of training in USA and varied experience here

    for those interested and don't know Fred, google ANDRA Andrew (Fred) Badcock, pretty sure his father was involved in the sport as well
