    Well everyone else is on the move so I will start here with mine.
    A little background: I came from the road racing side of the two wheel world of 125 and 250gp machines. When not racing I built custom grey market GP replicas for clients and sponsors such as RGs,RGVs,NSRs,TZRs and so on. The bike I am known most for is the XR86 Lucky Strike replica that has been featured in at least two dozen international magazines such as GLI Speciali Di Motociclismo(Italian),Road Rider(Japan),Café Racer(French),Street Fighters(UK). I say this in advance because I not here to promote or endorse any vendors.
    Anything I find or complete is free information and my sources are available upon request through pm.
    I Started with a base model with no windscreen and base rims and tires. Installed the clear blade windscreen(found it to rub the painted interior panels but buffered the two spots with clear round silicone dots), Also the hardware provided by Polaris for the Blade screen bracket were not cut to fit flush with the recess in the bracket. Two tapered 6mmx100 Ti fastners(25mm long I think) made it clean.
    [​IMG] A NRG shift knob(was simple but needed a aluminum spacer and some TLC to keep it in check and not make the boot look out of place).
    I saw a gent on here talk about and install a Xaxia Alloys bar mount mirror so with a very minor amount of work fabricating a flush base for it to rest on and a rubber washer with the same shape it mounted right up with a 6mmx100 50mm long tapered Ti allen(no more vibration than the outside mirr
    The steering wheel was purchased from Momo and installed on a Razor hub which has been modified for side entry of a coil wire and then run up along side the shaft to operate the horn(An Assault hub has been ordered). A set of Motegi rims(MR120 17x8.5, 35offset &18x9.5, 45offset) were also ordered and BF Gforce Sport C2s installed(245/40/17, 265/40/18). Fresh air was a simple install. All the 3"tubing and fittings are available from a dozen companies such as Radiant and the emission and sensor bung as well. Xaxia Alloys also makes CNC brackets to make a clean mount for the tubing up by the center headlamps everyone else likes to mount to.
    My wife kept dragging her feet on the interior frame railing so roll bar foam was installed and I took some paracord and made her a handle on the metal grip of the passenger side. I am not sure how much weight can be shed but I am looking into appropriate titanium fasteners to replace the steel bolts around the chassis, [​IMG]
    We had a saying " every 7 pounds is a usable hp".
    So there ya have the first steps of my build. Will post pictures as soon as I have loaded them to my website and link them here.
    Thanks for all the free information gang.

    Sweet looking build. Have you noticed a major difference in rear traction compared to stock with the new tires?

    The BF tires were like ice the first dozen miles and then after that they steadied out and began to perform. I expect a lot from tires and right now they are acceptable but I am far away from a complete package(still needs shocks and brakes). The BF tires are great for touring around:cool: I imagine once I have a chassis that is functional I will look at compounds but who am I kidding, I am on puplic roads:(
    These are cool street legal toys:woot: Personalize them:cool:

    Does the rear view mirror do any good or obstructed by the fin? I also have a mini gp back round, hobby turned career! We have built some of the sickest mini's you have ever seen, I'd like to see some of your stuff.

    Funny the things we now do in retirement:rolleyes: I also wondered just how much I would see in the mirror. Lots of blind is now seen. I was surprised just how well it helps(seeing is believing).
    When you said minis are you referring to the pocket bikes? or those WERA minis? I would also like to see a pic of anything with two wheels.
    This is of a 85 RS250RFII I kept at the shop until a collector gave it a home in Ca.

    Got tons more if you like this sort of thing. Just don't want to offend the rest of the gang with too much off topic odds and ends;)
    Got to shower and do some range work(new hobby):eek:

    I've been to a few track days and seen a bike like this destroy liter bikes! Pass him in the straights then kill them on the brakes :D I got very popular with pocket bikes then mini gp customs and gradually progressed to anything with 2 or 3 wheels;) Awesome bike, it looks fast just posing for us!!
