    No Rob, not heresay, I don't deal in that, have dealt with one or two sets of heads with the problem. I believe Ritchie is aware.

    Poorly worded on my part there Duncan sorry. I wasn't trying to imply that you did. I just wanted to be aware of any potential issues.

    my moorespeed valves are very good. just over 3,000 miles on them, have checked the clearances twice and haven't needed to adjust them yet. the engines remains very smooth and quick. very pleased.

    I changed the collet groove detail on my valves when I did the first prototypes in 1991. to stop the valve rotating, as any engine builder worth his salt will tell you floating valves are a bad policy, its called evolution hardly any europen or jap engines use them, I had my first test set in a r100rt that did 70miles a day on the motorway they now have over 60000 miles on them and I inspect them every year. my valves are made for me by the same people that make them for cosworth, so you get a better product for less money bacause there is only me and the manufacture, where as when you buy your BMW valve the manufacture makes his profit then BMW AG then the shipping then BMW north America then the dealer, work it out,I could have valves made the same way for a fraction of the cost but why would I want to make an a product that is not as good, plus as soon as you start to use higher spring pressure and more revs the heads just drop off god knows I have seen enough.

    Please verify:

    • The first test set of valves referenced in your post was installed in or around '91?
    • The first test set has over 60,000 miles of use to date?
    • What's inspected on the first test set every year?
    Thanks, Carl

    My Moorespeeds are still going strong and still haven't needed any adjustment.

    My 100 PD has a valve issue. The valves and guides were done just before I bought the bike so have only done 25k. As soon as I find the time I'll pull the heads and see what make the valves are.

    I just talked to chipsdad.

    Apparently the Chipper can be an issue with the computer!

    That's his story and he's sticking to it!

    So subtract one from all the results when you look them over.

    I voted earlier with no problems, but after 26,000 miles I can say now I've had a exhaust valve fail.Also used the Elco uprated guides. I suppose it's possible that there was to much heat and maybe the valve seized in the guide??? It wasn't a hot day but I had recently dropped the MJ down one size. May not have been the cause but I'm throwing that out there.

    Hi Les, didn't notice your poll going on here - and listed my response. I've actually got about 8 seasons on the original head work that came with the bike when purchased, the last roughly 5 with induction "forced" onto the program.
    Not to hijack your thread, but how's that MS project coming along? Had her running yet? (trust you remember me, we exchanged thoughts on your triggering design well over a year ago on the MS forums I believe.)
    Regards, Lorne.

    Hi Lorne,
    Like most projects, going SLOWWWWW.

    I need to make a push for the fall when it cools down, getting ready to order most of the last parts order. Winter is our riding season. I need to paint and that's better in winter here as well. Thanx for asking! I did buy the MS, it's just sitting there sneering at me presently...

    I hijack the thread just a tad more here - did you end up going with one of the small chopper wheels to mount behind your Bosch rotor - that you had been looking at? If I remember correctly you had been trying to determine if the close proximity to the alternator fields would be an issue. What I would strongly recommend (here's me coaxing people to engage with MS) would be to do some "pre-build" testing on that trigger arrangement to avoid the all too frequent commissioning challenges that can occur later in the build when the bike is sitting in the garage and won't sync and/or start.
    Even if you don't have that trigger, you could machine a temp tester wheel and run up in a drill press with the sensor of your choice, connecting the ecu to Tuner Studio and taking test logs of the tooth form and registry. Very little additional hardware required (most of the normal sensors can be left disconnected and ignore the readings in TS for those). I performed such a test when I transitioned to "Sequential Ignition", and for my 36/1 crank wheel with single cam tooth sensor I found a 72 tooth ATV sprocket and removed two opposing teeth. Adding one tooth to the disc for the cam signal I was then able to spin the one part and replicate the two different signals using VR sensors very accurately. True to form, I found issues with the single signal needing to spin up faster than crank speed for a reliable sync so pursued a "conditioning circuit" to enhance and clean up that cam signal to gain very reliable sync and signals.
    You would be able to do that kind of thing and put some EMF's in the vicinity of the device to prove out the interference aspect (I believe you won't have any troubles with that).
    Best of luck on project,
    Lorne.

    I attached a PIC of my setup I plan to use.

    I got the wheel and sensor from Silent Hektik. The wheel was 4+1. I did not think this would work real well and it would need custom programming for Megasquirt. So I had a new wheel(outside rim) made for it as you can see. This should be plenty of resolution for a Flat twin and is easily setup in MS. Thanx for all your feedback in helping me plan this, much appreciated!
