Nice work on the pipes!  Your welding skills FAR exceed mine  :)

Thanks for sharing your bike with us.  Race bikes are always interesting and not often do
we get to see a Vision racer.

One of the next things I want to try are Venture carbs.  See my posting under carburetors.

Race 1 the VRRA required oil containment pan was scraping on the right side due to the layout of the MAC front pipe and soggy rear shock.  I salvaged a Wolfe exhaust can from a free parts bike (the balance of the Wolfe pipe was too far gone) and fabricated a new transition with a few pieces of mandrel bent tubing.  A CBR shock was installed before Race 2 and handling is much improved.

Further to Jefferson's comments re possibly shorter forks... I wonder what effect on steering geometry and handling that may have. Also about rake/trail, what about the fork being a center axle design? Did the fork swap also have modification to account for that?

CBX, is that a catch pan or part of a fairing under the motor?  Is this something required by current rules?
Since that was handled in PM and others may be curious....
There was a discussion on another forum w/a vintage racer and while it was not current to this season, the catch pan was required. For wet sumps like the XZ the capacity had to match oil quantity. The dimensions had to protect the case, gearbox, and oil filter. There were rules regarding acceptable materials and likely other rules I'm not aware of.  :D I think there was a recommendation regarding having oil absorbent material in the pan suitable for that quantity of oil but it was not a requirement as of that discussion.

I put one in that I got from ADVmonster. Single unit with it's own cooling fan.Called the native H4.Works great,but I did have to slightly grind the opening a bit for it to fit/pass through the opening. All the tabs fit correctly.Right now there on sale for $40.

I have no idea if it lights the road better than my old 5x7" halogen, but at least it should use a lot less power, and save his stator. 

That's what prompted me to make the change although some would argue this point. I also changed the two 1157 taillight bulbs with LED's. My dash mounted volt gage used to dip noticeably with brake application but no perceivable movement with the LED's. People who have followed me on rides comment on how bright it is too - all the better to be seen. The 1157 bulbs are 32 watts a piece (if memory serves) on the brake filament whereas the LED's are 1.2.


It's got me looking for a 5x7 version of the same sort of LED headlight for my motorcycle.


I might not be understanding you correctly but the LED light I'm using is not a sealed beam. It is a bulb that replaces the halogen bulb and fits in the back of the original glass headlight assembly.

One of the young guys at work has an SV650, and he recently mounted an LED headlight with two projector lenses in it.  It's a 7" round headlight, but it looks pretty impressive.  I have no idea if it lights the road better than my old 5x7" halogen, but at least it should use a lot less power, and save his stator.  It's got me looking for a 5x7 version of the same sort of LED headlight for my motorcycle.

From that picture it's hard to tell if you are on the brakes or throttle. It appears those forks may be shorter than the stockers which is going to give you less ground clearance, but then you may be on the brakes just not hard as can be determined by your zip ties. I would imagine the brakes are quite a bit better with that caliper versus the stocker. Keep us updated on your experiences racing and what you do to the bike. I can see a pretty good thread coming from this.
