^I don't know where to start.
-Brazed frame joints instead of welded??? Could start there! Very dangerous!
-3 cable throttle similar to the the first gen CB750 that went out of whack all the time.
-Carbs up front and exhaust out the back is not so odd but roasty-toasty toes with exhaust exiting to the side ahead of feet.
-fuel tank at the rear sloshing around could be troublesome.
-Hand start with recoil...funny, odd and likable all at the same time.

-And this one....

 

Oh, I wouldn't be so quick to judge the brazing of a frame. After all, it's good enough for Guy and Michael at the Manx GP. (M. Dunlop has a 120+mph lap on it)

TIG brazing - nickel bronze rod. Trident Engineering. GS1000


















You have to remember, they're not using standard brass rods. And as thin as the tubing is, they keep some of the strength lost by welding (heat). As for everything else, it's a 700cc snowmobile engine (which is why it's pull start). The carbs in front/exhaust out the back is it's natural orientation for the motor.


But yeah, there's probably a bit of heat on the chestnuts. No denying that.


I saw it on FB, can't find a build thread on it. But judging from the forks/wheels/shocks - I don't imagine its a street bike, and I can't imagine he'll be sitting at a stoplight on that thing (which would really put the heat on the ole boys)

 

Hey Marc, if the motoGP thing doesn't pan out for you, maybe there's another calling...

 

2 things, those do look more like welds than a normal braze and the color is lighter than a normal braze. I haven't brazed in years and didn't know they introduced alloys to the stick.

Apparently, those joints are (TIG) brazed without flux with a nickel based rod. I can see nickel making a strong joint and the brass providing the wetting.

Here's an interesting LINK I found.

edit; tried to fix links but failed again.

 

Those kneeslider links never imbed... I can't stand it! I can't imagine how much time I've spent trying to track down bikes that I found on there so that they'd actually imbed.


Here's some more pics of it.

 

Cripple Triple GSXR 450


GSXR 600.

In a nutshell

• #2 Cylinder valves removed. Then RVT silicone the guides.
• Freeze plug on exhaust tube.
• Velocity stack routed out of air box.
• TB/Injector luped into tricking ECU that its functional when it's not.

This is a way to race in the 450 class without having to build a 400cc motorcycle. They can still make about 60ish hp and 30ish lb/ft.

No real picture needed. But a cool concept. It beats trying to find an differ 400 as opposed to an $1800 tracked Gixxer

 

 

I like it a lot......

 

Mechanical driven turbo....interesting.
