    Haven’t posted around here for a while, just thought I’d share the latest list of upgrades. 
    Bike was last dyno’d at 125hp 135 ft pounds. 

    The list of changes are, 
    Fresh pistons and rings, cylinders bored/honed +.010”
    625G cams replaced with 640G cams
    55mm throttle body replaced with 58/62mm throttle body
    4.9 injectors replaces with 5.3’s
    Oil pump replaced 
    Heads services by hoody, valve springs replaced. 
    Exhaust changed to D&D fat cat. 
    Assembled and tuned at Neville Lush Racing. 
    Made 143/143.

    Picture shows as it sits now and how it looked when I bought it. 

    Cheers Dylan

    Nice work, it's a good thing you've got the new seat or it would blast you off the back onto the road when you twist the throttle.

    Impressive in every way! Not to be a negative Nelly but are you still using your factory bottom end or replaced/welded things up?

    looks good on paper, have you taken it to the track at all?
    And any problems with the rear wheel spokes?

    Thanks boys. 
    JD - the seat is so much better when you give it a squirt. 

    FB - the crank is an R&R cycles 4.500” stroker crank balanced and welded. Run out measured at .0015”. To be honest I’m no expert on any of this, I just ride the thing. 

    KK - haven’t had a chance to run it down the track, but it is on the list. For the meantime I’m just terrorizing the streets. 
    What do I need to look out for on the rear wheel? 

    Cheers

    Fuck thats got power /torque, definite as KK says, out at the track.
    Was just thinking years ago you could have a few drivers licences, through no fault of your own.
    Example : I lived in SA, then went to Qld for a year, back to SA, briefly, then on to WA for a year, then with NT being lived in, for over the period to change to your licence, then passing to NSW, for a period. 
    So you get the idea, some peoples had multiple drivers licences, as you would definitely need if ya hit it on your rocket.
    Sadly, can not comply like that anymore.

    DJP missed your question, well I only had a little 95 c I d twin cam dyna, carb . I was taking it to the track all the time. & it could run constant low 11's. I road it to willowbank QLD a few times & home to Sydney, also went down Heathcote VIC once, mostly raced in Sydney. started with stock HD spoke wheels, I noticed the spokes on the drive side, where they hold to alloy hub. Had turned all the holes in the hub like egg's so put a stock HD cast wheel on rear kept spoke on front ( I love spoke wheels ). also even though I never broke a belt drive, I thought as I road to QLD to race then road home to Sydney, I thought it wise to change to chain drive & also had an outrigger bearing support to give the axle more support, as I had bent heaps of rear axles in past on Harleys I owned that I raced. then next thing to happen was every bolt holding Sproket to wheel, broke off on start line, I was doing quick 60ft ( for what I had ) & the track had a bit of stick on the line, was bracing for the rear thrust & one of the broken bolts, stuck between Sproket & swingarm, locked rear wheel up & went over the bars about 60ft from the start line. also another time I broke the rear rubber mount.
    Having said all this the 88" sporty I have still has stock HD spoke wheels & belt drive, it goes hard but never been to the track yet ( live about 300km from track now ) have not had on Dyno yet as an old Carb& still running it in (17,000km last I  checked ) but I'll be on Dyno to tune it soon, just to check afr is safe up high.

    Thanks krash, I’ll keep an eye on all the things you mentioned! 
    I plan on going away from the spokes sooner or later for a set of mag wheels. 
    Would really love a set of BST wheels, but the price scares me and need to do some research Them a bit more. 

    Cheers
