    Hi John.  Why the 80inch sign over the 110 motor pic and where'd you find the frame?
    I've been looking for a straight later WG frame for a while.

    80in was just mucking around, unless you're the authorities then its real and actually 80in haha

    Frame was found via fb and someone parting a bike out. Theres a dude on ebay that sells wrecked bikes and Harleys. Youve gotta buy the whole bike though.

    Are WG frames different to normal dyna frames.?

    The 2010 up WG frames have a 34 degree rake vs the other Dynas 29 degrees. 

    I saw a wrecked one but it wasn’t for re registration and gringing off the frame numbers wouldn’t get it past those nasty authorities as you called em.
    They are listed as a part, got the number etc but HD refuses to sell me one unless I hand over an exchange frame and to get that I have to buy a whole wrecked bike $$$ too many.

    Hey RatBob , are you sure the rake is in the WG Dyna frame and not just done via the triple tree's? myMate had both a Dyna WG & a Dyna Sport, I could see the rake but never really checked out how factory did it ( better via frame. )

    Found a decent set of the calipers I was chasing. If im lucky, they'll clear the spokes on the 9 spoke mag. If not, itll be back to original plan of rotor adaptor/spacer and a 300mm disc. 

    Radial calipers wont clear the spokes on a 9 spoke mag fyi. Need to run 13 spokes, then you lose the mechanical speedo drive. 

    I need to have a good look at the wiring for those tranny speedo sensors. The delkrom and trapdoor have a provision for this speedo. So if i can lock that in, when i get the front end sorted i wont bother with a mechanical speedo provision.


    John look's good, if caliber does not clear the spokes could you have wheels machined in a lathe to get the clearance?

    Will have to see. With radial calipers you technically can, but you need to remove a substantial chunk of material on both sides of the spokes. I dont really consider it an option.

    John ,might be easier to custom make triple tree's, to set the forks slightly wider apart .

    Yep thats already happening, which is why im not fussed. Theyre needed for length and geometry reasons.

    Yeah thats going to be nuts. I think its Jeff Holts.151ci. Needed a bit of chassis mods to get that in though.

    You have to wonder what happens with these project bikes. They spend years in the build then they just dissappear. The S&S powered FXXXR a few years back was amazing, never saw it since.
    Looking forward to see yours come together

    John.R, have you done a trial fit of the TC into frame yet? I did a TC into 4 speed frame a few years back and this frame had been modified (Mangled) previously to fit an EVO. I had major issues with rear rocker cover to backbone clearance that resulted in having to do major frame modifications. I have no experience with FXR frame dimensions but might be worth asking a forum member that runs an EVO to get some crank center line to top rear rocker cover dimensions so you can compare.

    Nah not up to that, gotta tap engine oil holes and take some meat off the tranny pad. But there should be no issues regarding fitment, it's not a new swap, and its been done before. Rear rocker clearance is tight anyway lol.  Here's my Evo

    More parts. Harley dealer had a good deal on this Barnett clutch, half price brand new.

    Cheers Tussuck! Very happy with the Evo. Going like a rocket after the rebuild, smashes Kays no drama, and the bags are handy as. Ive got a Crane ign module to go in it, just need to update plug from old 7 pin to new 8pin Deutsch, which just arrived at HD today. 
    I sent you a PM about your bags a month or two ago, Im still keen to grab em haha.

    Hey RatBob , are you sure the rake is in the WG Dyna frame and not just done via the triple tree's? myMate had both a Dyna WG & a Dyna Sport, I could see the rake but never really checked out how factory did it ( better via frame. )

    Hi Krash, If you look in, say Ronnie’s Harley partsfinder you’ll see the frame listed for the 2010 up WG’s is speked at 34 degrees and the Fatbob’s etc 29. Some say there’s another 2 degrees in the yokes but I’ve not measured it.

    Thank's RatBob, I could see the extra rake, just looking at the bike parked.
    they both handled good as my mate had the TC Dyna WG, then got a TC Dyna sport & he got knack rake even steeper by putting 1.5" longer Olins shocks at the rear & slipping fork tubes an 1" through triple clamps. he is a good rider ( raced at Isle of Man in youth Manx Nortons ) I think he mostly changed because he was runing out of brakes on single disc WG. but he was quick in twists on the Sport must have been about 27 degree on that.

    Back to the FXR TC, John , how long do you expect the project to take?

    Not sure just yet, few months probably with whats coming up, xmas, holidays, trips etc.
    Biggest limitation is cash right now. Burnt through a fair bit getting most of the big items out of the way. Still have carb, ignition, wiring, motogadget, triple trees, big discs.

    I need to research wiring diagrams next to see how the transmission speedo setup works and how I could do it.

    Once i confirm that, thatll determine if i need to incorporate a mechanical speedo drive or not on the front wheel / axle setup.

    Not much to report.
    Got a bloke kindly lending me the tap and fixture so I can accurately tap the oil lines on back of motor. 
    Then gettin a local bloke to mill about 4mm off the front of the tranny case so it clears the adaptor. From there I can start test fittin motor in frame and seeing what the go is.

    Started getting quotes for wiring setups... it knocked my socks off. $4.2k. Granted this included the motogadget, all ignition module and gear, ignition loom, custom main loom, and a bunch of sensors, but still..

    Decided im going to sort it out myself, which I think is doable.

    Namz make an OEM replacement ignition harness, which has all the pickups i need. Crank, map, etc. That will plug straight into an early TC style ignition that uses the 2 x 12 pin sockets. Most of these ignitions only need the basics hooked up to run. I figure using this as the base, getting all the sensors I need, worst ill have to do is change some sensor plugs for earlier OEM style and ground a few things out. The Motogadget also has Aux circuits, so Im thinking ill be able to hook these up to the electronic compression releases.

    Anyone know if crank angle sensors all mount in the same way? I.e would an older TC crank angle sensor with older plug bolt straight into to a newer motor? 

    Also anyone have any opinions between Daytona TwinTecs and Dynateks for ignition modules?
