I am using a 2004 GSXR 1000 front end and wheels and 2003 GSXR 750 rear swing arm I got from my local wrecker

 

[XVR]

One of my first projects was to make a new set of engine covers....my cnc guy cranked these out in a few hours.

 

[XVR]

Did a mock up of the rear swing arm to get a dimension for the chain drive conversion....the rear tire is a 190

 

[XVR]

This is the cad model I drew up for the chain drive conversion. Tha shaft is case hardened 4340. Tha small end of the shaft runs on needle bearings and needs a min hardness of 56rc. The bearing adaptor ( blue part ) has two deep grove bearings with more than enough load capacity for the 100hp I hope to make.

Stopped by my buddys cnc shop yesterday with a case of beer and I walked out with a pair of chain drive shaft blanks.....good trade...lol

 

[XVR]

This is the model for the frame brackets to help tie everything together. It will also be used as the mounting points for the tail section.

 

[XVR]

The four cylinder two stroke is a 1600cc motor I built for my 320hp trail sled.....fastest thing I have ever been on.

 

[XVR]

I will be building an under tail exhaust. Traded a fish finder for a pair of Hindles....and a few beer....lol

 

[XVR]

The seat frame will be lightweight alum tube. The tail lights will be led and also serve as turn signals. I weighed the bike today with everything on it except a battery and lights and it came in at 340lbs.....that GSXR stuff is really lite

Going to run a pair of Keihin 39mm FCR carbs. The accelerator pump in this carb gives you wicked throttle response.

 

[XVR]

The motor is out and dissassembled. Going to put it on the milling machine and make a few cuts.....

 

[XVR]

Finally had some free time to machine the case today...didn't take long....can't turn back now...lol

 

[XVR]

Did a little CNC work today. The adaptor plate came out really nice. Turned up the bearing support on the lath.

 

[XVR]

Fits like a glove. Just need to finish cutting splines on the new shaft .....

Hey Man, Your are one SICK DUDE!! And I love it!! When you put the frontend on your bike did you have to make a new steering shaft? I am looking to put an R1 frontend on mine and was wondering what obstickles you can across with the triple clamps and help will be appriciated. Keep the SICK work coming, I feel like a junk waiting for his fix!!

First you need to find bearings to fit your head tube with your new front end. The bearings for my bike came from a 1978 Kawasaki 1000. Then you need to press out the triple shaft and have a machine shop make a new one to fit the new bearings and the new triple clamps you plan to use. Mild steel is ok but if you want to upgrade you can use 7075-T6 aluminum like I did.... it's stronger than steel..

Amazing is an understatement! Subbed for sure and while your at it pop up another pic of that 1600 Rev, the engine bay in mine doesnt look anything like yours!!

This is me warming her up in the driveway. This thing is nasty...145mph will keep you honest...lol

 

[XVR]

Wow, that looks really good mate.

It's easy to tell when someone knows what they are doing, have the knowledge/experience and the tools to make a bike like this. Great work!

If I might ask, how long have you been working on/customizing vehicles/bikes?

I have been working on crap for over 30 years....yup I'm old..... this is my 1972 Massey Ferguson lawn tractor that I'm working on..... I have a problem....haha

 

[XVR]

I had to widen the wheels 3 1/2 inches for the heavy duty AG tires......I know it's not a bike......forgive me.....lol

 

[XVR]

Finally had some time to work on the old bike. Doing another mock-up of motor before final assembly. Everything looks good.
