Underseat radiator

Worked out really well actually.
I initially only ran one fan which was ok as long as I stayed below high roadspeeds in high ambient temperatures.
Once I realized that one wasn't enough I added another fan which would cut in if coolant temps reached 210 F.
I tried a number of ducts and different extraction methods but found out that air never does what you expect it to and ended up with what you see in the pictures.
One question that came up more than once was whether the seat got hot. No it never did.
BTW, the fans were the stock pusher fans that would push the hot air down through the radiator towards the rear tire.
Radiator used was '03 VTX1800 with a mix and match of coolant hoses from a variety of bikes and cars.

The reason I went to the underseat radiator is that I never could stand the naked VTRs that retained the stock side mounted radiators, it just looked unfinished.


Glad you like it,

Does converting a CB400/4 into an XR460 Four count me as a a freak?

Hatched from the same incubator, and I might add, a true mad scientist indeed.

You might even be considered for a "Mad Max" award.

I get that more often than I should expect to, especially since that article was published in July of 1991. It was Motorcyclist though, not Cycle World.
Good eye though since the bike changed color since then.

Its been a few weeks since I posted about my own "Freaks" progress..so here's a bit of candy for those of you whom are interested. I'm working on three monsters at the same time since parts searching on flea-bay tends to take some time. It seems it would be easier to rob graves.

This is what Frankenstein Started out as


This is how it looks today. 1999 CB 600 F2 wheels with 1985 cush hub to allow fitment in stock swing-arm, machined .0030, sprocket machined down to accept 520 chain. 2005 CB 600 F4 rear shock is currently being fabbed to fit. Front- 2001 CB F3 forks with F# calipers mater to F2 wheel. Minor machining to spacers to turn smoothly, Triple clamps are custom machines using stock XR bearing set and stem.









Freak # 2- The Barnsdorffer Special. Don't ask about the name. It just showed up in my head, so I found something and came up with a concept. Still not sure why. Created this to start my project.


2006 Honda XR 650 L



Here she is today. By the time you see these pics, it will now be a "hard-tail" instead of suspended.

Front forks from my XR 650R with machined triple clamps. Rad Eagle Wheels mated to 18" Excels. Tires are Coker "Firestone Indian's". Motor cases have been ground to remove any logo or emblem and are now black crinkle powder coated. I am in the process of adding fins to the head and cylinder, then they will be black with the edges ground. Engine mods are stage-2 cam and porting, piston, and Falicon rod with balanced crank. Pics coming in a week or so. The next phase of this one will be veeery interesting.

1972 Yamaha XS 650- Shell Thuet 750 Track-Master Framed Street Tracker



I bought this motor in a stock framed Street Tracker conversion from a Full race bike. I ran it about 110-115 mph- with not front brake on the street until the butt pucker got ahold of me. Updates as soon as I get the swing-arm and wheel set fabbed.

Hoping this gets others going. I know there are more of us.

Dunno how I missed this forum, but glad I finally found it! Can't wait to see what you've got planned for that 650L. Building a few XR600/650L's right now too. But haven't been able to spend much time working on them lately - too busy working on my motorhome and launching the GatosBros product line. Have a few build threads that I started over in the thumper forum.

Barnsdorffer Special Updates

New parts arrived and I am dilligently moving forward with the "Barnsdorffer Special", formally a 2006 Honda 650L. WTF is a name like that? I was called Barnsdorffer in highschool. Hated it then. What better for a freak bike...



Remember this WAS a 2006 Honda XR650L


Just a few changes...


Tank is off a Rebel . Forks are stock XR650R. Clamps are Applied Racing. Wheels are RAD Racing 18 inch x 2.15 with Excel wheels. Tires- Coker "Indian's"







Closer next week.

FrankenStein Updates

Moving forward on FrankenStein, pronounced: Fronk-in-Steene for legal purposes. Hey you don't want to piss off the Germans, or the Austrians, or whomever made the movie. TrackMaster Triple Clamps made and hopefully a complete front end by next week.




So, here where I am so far; My 2000 Honda XR 650R bought new in 2000, with the following parts carefully disected from donor bikes found in graveyards. 1999 CB 600 F-2 wheels mated to 1985 cush hub, machined to fit. 2004 CB F-4 forks and Calipers, 2006 CB F-4 rear shock in place of stock. Sub Frame is currently from a 2006 Honda CR450X, I need a place to store the battery, Seat isn't designed yet. Tank will remain stock but radiator shrouds will be cut to allow for modified exhaust running under frame and mated to "Yosh" Tri-Oval. Radiators will need to be shortened and made thicker to get the same cooling capicity. Next on the list is a Euro-650R electric starter assembly-frickin' expensive but will be worth the money in the end. Anybody have an extra Euro case set for sale- I'm in need. FrankeStein would be so much better with electrics. Stator has been done by Ricky-Stator so juice shouldn't be a problem. More pics as I get closer.
