Starting build thread on my new duner/hillshooter. '87 Zilla chassis as the base with a '91 GSXR 1100 powerplant. Primarily setting the bike up for dune riding and hillshooting. At this point I am planning on running Shaw coilovers on the bike. Also already have a Lonestar drag axle and +12 ladder bar swing arm.
I am going to have the 1100 dyno'd next week (still in the bike) to get a baseline to start with. Multiple people have said that the header design is huge on these motors. So once the bike is done, it will be run again in the Zilla chassis to see where the numbers are and what we have to change on the header.
The '87 frame was tweaked pretty good in the nose. Had the frame straightened and sandblasted. Going to start hopefully cutting and removing brackets and the lower rails this weekend. Once the 1100 is dyno'd out of the frame and into the Zilla it goes!!!!!
I will be taking pictures along the way for the build thread here. My time frame is the have the bike done (are they ever really done though?) by the end of April. I want (will) to take the 1100 and my other 500 to the Raptor Rally at Winchester Bay May 17th-19th

Here is the donor powerplant. It is a '91 GSXR 1100. Have already gone through the carbs, removed the airbox, rejetted and installed 4 Uni Filter pods on it. Goes to the dyno this week and then we will pull it out of the frame. Going to try and recoup some money by hopefully parting out the parts that are worth it.

Here is the swing arm going under the bike. It is a +12 ladder bar setup from Proformance Prototypes. Really light weight and set up for a 17" shaw coilover. 40mm carrier with a Lonsestar drage axle. Setup to run Banshee brake mounts etc...

Not sure what the final weight will be. I can weight my buddies and let you know. Are bikes will be very similar. His is setup for the strip though. We are going to do a set of drag lite arms and spindle mounts for his.
After he built his, it was apparent you can't build a bike that is really good at both. Good drag bikes don't dune well and good dune bikes don't drag well!. There is no perfect answer to the build. I want a nice comfortable duner/hillshooter that will hold its own with a good pecentage of the bikes when it comes time for the grudge drags out in the flats. That's all...
Obviously giving a weight advantage to the banshee, but I think it will hold its own!!! And I won't be nearly the amount of $$$$$ into it like some of the Banshees and Raptors out there that's for sure.
Not to mention it will still be Zilla based and look like one too!!!!!!!!!

That oil cooled 1100 is a very stout and reliable motor. Good choice!

This is gonna be a wild ride. I would love to see it compleated. You are gonna have to run some serious paddle tires on that thing.

One of the reasons I chose the motor was they are pretty bulletproof.
Gonna run 12 paddle rippers with @ 72-75 RO and a 60 tooth sprocket. That should do the trick!!!

Had a fun night on the dyno machine!!!!! Spent around 3 hrs tunning the carbs and running it through the paces. After 5 seperate pulls on the machine, we ended up with some great numbers!!!!!
It made 127.73hp and 77.24 max torque at @10,000 RPM!!!!! Really happy with how it finally turned out. Started off pretty weak and then just kept comming on and on and on!!!! Nels, the guy that did the running on the machine couldn't believe the numbers we saw out of the bike. He said I should be extremely happy with them.
Now that that is out of the way, I can pull the motor and really start moving.

These also showed up on the prch the other day. Triple buff 22x11x8 12pdl rippers. They have a R.O. of 72'' and should do the trick.

My buddies bike has your old 12+ DMR swinger under it. We have used alot of how you setup yours in his build.
That should be enough power I think for just cruising around the dunes. What do you think of the paddle count? Works good on the other bike. I know that Jordan and you were talking about 81" ro at one point.
Haven't had the time with holidays to do do much. But over the break we are going to hopefully get the motor in the frame and possibly rolling if all goes well!!!!! Keep your fingers crossed and I will post pics as soon as the sparks start flyin'!!!
Merry Christmas and Happy Holidays.

depending on its purpose,gearing,chassis setup and hp its hard to give a paddle count.. but i would stay with a 25" tire. i posted a video in the youtube section of my bike at raptor rally... i also posted pics in the photo section

Why do you like the 25" tire? Is it the extra ground clearence you pickup? Or???
-
-
-
yes that too but you get more traction and the tire flexes well. i have tried 22 and 25's and i have had success with the 25's. maybe for a duner occasional hillshoot it wouldn matter much, but im 1 purpose

Unfortunately no real updates. To much holiday stuff and the flu running through the house didn't help anything!!! Got the shop cleaned up a bit and the motor pulled though. Hopefully tomorrow we are going to get some progress made. Will post pics as soon as it starts going...
