    Finally got around to doing my own bike after playing with it on the dyno a few times sussing out gearbox transfer (fixed) 

    Pipes are Rinehart Motopro 45s
    Header is OEM 
    Filter is SE stage I conversion of OEM. 
    Tuner is a MasterTune. 
    Bike made 105/105 @ 27C/75%

    I can highly recommend this set-up. Retaining the OEM hat on the filter stops you hearing any filter-suck. The Rineharts are smooth on trailing/steady throttle but bark up nicely under power. 

    MasterTune make the OEM SE tuner so they're easy to use. 

    Next are a few anti-sumping mods and then Stage 2 will be a Woods 22X cam, S&S low-bleed lifters and Smith Bros adj. pushrods.

    good stuff Nutty, did you use the fat push rod to stop fluid transfer or go another way? Considering the fat push rod for mine, just haven't got off my arse and ordered it, only transferred once.
    I haven't had mine dyno'd, just stage 1 map with a few smart tunes (using orange SE ProTuner) but very happy with power delivery. SE high flow filter (round style) and 2nd hand street cannons as on a budget. Could be a bit louder, but not too bad to be honest. Trying to work out the best way to add external breathers with this filter and backplate set up at the moment.
    Interested to hear and see more on your anti-sumping mods if you care to share.

    Correction: Someone left the power scale attenuator on the dyno up...grr

    Re-tuned it this morning as it was hard on fuel when road-testing yesterday. Set it to stoich right through, did 91/108 @ 22C/80%.

    Doc: our anti-sumping experiment is pretty involved. I'll post up some pics once we give it some test time. 

    Re: anti-transfer. No fat-rod used. The fat rod stops transfer but also allows pressure to build up in the primary. Not good for oil leaks...

    Ours is a two part mod. 
    1) A KTM fuel tank one-way valve allows the primary to breathe in from atmo whilst still venting through the cross shaft as per OEM.
    2) A small machined valley in the gearbox trap-door and a bleed hole in the S/C mating surface allows gearbox oil in the S/C cavity to pump back into the box rather than along the cross shaft. 

    There's two separate leakage events going on here IMO.

    Keen to see the difference you get after your next round of mods, keep us posted Nutty.

    Nice setup and great to hear some proactive work on these potential m8 issues. I understand the 4.5 inch Rinehart muffs have the same standard 2.25" louvered baffles as the 4 inch Rinehart mufflers. The mufflers that can cause issues in terms of performance are the larger 2.5" cores, tapered, or stepped baffles that are in some of the louder mufflers being marketed from what I’ve read.

    Just regarding one comment above - I’m running this clutch pushrod......4000km to date with no abnormal operation that I can detect. I’ve just been talking with the fat rod manufacturer regarding his rod......The fat rod has a machined flat along its entire length. This allows the primary to breath. According to Greg, the maker, he has a test bike with over 15,000 miles issue free. He did have some QC issues with some rods which he says are being addressed but the primary breaths just as it did with the stock rod, at least according to him.

    I guess any issues will become apparent given the ease of internet communications.

    Re: The fat-rod set up Dan. I'm keeping an open mind on it until the retailer describes what he thinks is the technical issue AND how his design is a fix. The one you have has a machined-flat, some others don't. I'm not a fan of "trust us, it works", that's 40 years in Engineering coming out I guess. :-)

    Sounds fair man! Didn’t know some were without the flat edge.

    Williams rod with the flat edge was version 1,his version 2 has no flat edge,I have version 2 but not fitted it yet (next oil change)
    Williams also says to change your transmission oil to 80/140.
    I had the primary vent fitted,at no cost as my bike did have a dealer recorded oil transfer problem.
    I have ridden just over 2k since the the vent was fitted and no sign of oil transfer as yet,
    I'm still running HD's 20/50 in the transmission and no transfer,but I intend to swap over to 75/140 next service
