Ozark Mountain Scramble 2014

Only a day separates us from show time, so I figure it was time to do a quick refresh on the day one meet up spot.

We will meet at 9 am on day one at 2511 N 2nd St #1 Rogers, AR 72756. Everyone can meet, greet, and go over the days route before departure at 9:45 am. I will have a few extra copies of the route map, just let me know if you need one. The more prepared you are, the better for the group overall, so please show up with a tank full of gas. If you are running a bit late, or have any issues that the group can help resolve, call Derrick at 479.621.1327.

There are quite a few gas station options from day to day, however there are a handful that only accept cash without any ATMs near. Be prepared and bring a couple Lincolns in your man purse.

OZARK MOUNTAIN SCRAMBLE 2014

A three day trip through some of the best roads in the country can't be beat. June 11th kickstands are up and the journey begins. Here's a few pics from the past few years to wet your appetite:

Got the head back together and the bike running again. Threw a cheap megaphone on to help add some back pressure. Unfortunately I killed the battery, so until the new one shows up tuning will have to wait a bit longer.

Head gasket leak ended up being more involved than originally thought. Some galling on one of the the cam bearings and cap. Found a new head and cam for less than $60 shipped that are in great condition, but best of all they came from the same bike.

Good.



Bad.







The left bore looks perfect, but the right has some flaws. No gouges or anything, but some water marks. At this point I am going to let it be. The bike barely wisps any smoke, and 440 rings/pistons are really pricey and fairly rare. There are big bore options using gs850 pistons, but that requires reaming the little end of the rods and huge weight reduction to match close enough to stock weight. I'm not ready to tackle that yet.



For the time being, I am soaking the gas tank in vinegar to get rid of sediment and rust. Hell, I may even start painting parts.

Took a 150 or so mile trip Saturday with some Ozark Mountain Scramble alumni to do a shake down run. I've got a few things to tinker with as far as jetting is concerned. The primary main needs leaned out a bit, and the secondary needs to be richened. Exhaust is in dire need of some back pressure which will probably help the jetting conundrum. On top of that, a slight head gasket leak popped up, so I am going to re-torque and see if that clears things up. If not I have a full gasket set at the ready to swap out.

As far as suspension goes, the rear shocks might as well be blocks of wood. Actually I think blocks of wood would be an improvement. The rear feels unstable and wants to wash out under any acceleration. All bumps are transferred directly to my ass and spine. I have ridden hard tails that are more forgiving. I have a feeling the kz1000 police shocks are just set up way too stiff, so I am going to sell these off and get some from a 750 or the like. The good news is that the Progressive fork springs are spot on, so just the rear needs improvement.

All in all, not a bad first trip, just needs some refinement.

I've been dicking around with the seat pan for way too long. I ditched my horrible attempt at fiberglass, and decided to work with what I know best. After some head scratching I got it all finished, and some foam carved up for some beta testing. After a few miles yesterday, I'm pretty confident I'm headed down the right track. The bike is running great so far, and seems to require very little tuning. I think it's safe to say the bike is Ozark Mountain Scramble ready.

We have been pecking away at the tasks to get this Ozark Mountain Scramble Ironhead ready for June 2014. Here in Western New York the riding season stops at the end of October so shop time is not interrupted by the desire to ride in sub-freezing temps until April.

The Rear spring struts were not doing it for me for the overall look of this bike. The rear sat too low and the front is too high. I found a pair of stock 13-3/8” long XL883 rear shocks in my stash that I removed from my wife’s new Sporty back in 1997. These brand new shocks have been in a box in my attic for the last 16 years. I figured this project was the perfect candidate to use these forgotten gems. So, off with the struts and on with the shocks. I like the look better than the struts on this bike but they are really soft and with my fat ass on the bike the springs compress farther than I would like. I guess we will be adding pre-load spacers to the springs to carry the extra load and keep the sag to a manageable level. We will post more on that procedure in the future.

The Ironhead motor will be losing half of its displacement when I remove the rear cylinder so we needed to give the motor a little help in the final gearing department. We installed a smaller countershaft sprocket for some extra mechanical leverage. We went from and 23/49 combination to a 19/49 combination. I pulled a few links form the existing chain so everything fits correctly. I hope this is enough to let this bike get out of its own way on the twisty mountain roads of Arkansas.

We decided to use the horseshoe style oil tank that came in the box of parts with the bike to keep costs down and mounting of the battery simple. The only problem is the original tank mounting system is flawed and parts are missing. I rigged the tank to mount from the original regulator/battery box iso mounts and reworked the original oil tank frame mount on the right side of the bike to hold that side and the third mount will have a custom bracket that ties the oil tank to the inner primary. I am hoping the iso mounts and the 4 point mounting configuration will be enough to hold the weight of the battery and 3 quarts of oil. This is all for now stay tuned for the next update for the rear tail section and foot controls.

I have fixed the exhaust, put a new battery in it and cleaned the carbs got it running
pretty sweet now.
I also put the stock fenders back on it front one had to raise a little cause of the tire sizes.
The rear one came with a Lucas style tail light and a stock style tail light.
I picked the Lucas style after careful consideration..lol it's a smaller light that looks way
better than stock in my opinion.
Now I got the fenders on and tail light working I can got register it and be legal like on the
roads and such.
Time to get rid of this seat and get a stock seat and possibly put the scrambler bars on.
I'm liking the ones on it now damn decisions.
That's it for now.

Happy Thanksgiving to you all!!

This project has been sitting for a month or so. I figured it was time to move forward and get the rear wheel mocked up and on the bike. That one sentence took a week of after work free time to get completed. First of all the wheel that we had acquired with the project is a later disc brake wheel. In 1975 the Sportster came with a Drum brake rear wheel. I thought to myself “No big deal we have a caliper and a master cylinder to use for this.” So I went to bolt the whole assembly up and what I realized is the later disc brake wheels use 3/4” Id bearings and the original drum brake set up used 5/8 ID bearings. All the original hardware was useless as is. What to do? I found a 3/4” diameter axle and nut in a box of parts but it was 2-1/2” too long. I cut the head off the original axle and drilled a 1/2” diameter hole through the center of the head and cut the 2-1/2” inches off and turned a 1/2” post on the axle then proceeded to weld the head back on. Next on the hit list was the axle adjusters needed to be opened up to 3/4” also. I went back to the lathe with a boring bar to make short work of this task. The 3/4” axle needs to ride in a 7/8” slot in the swing arm so 2 spacers with 7/8” flats were made to center the axle in the slots in the swingarm. The last piece of this puzzle was a 3/4 long straight spacer. I found a chrome one in a box from a previous build. All of our work bolted right up and lined up the wheel and sprocket like it was meant to be there. Next on the list is to fabricate an anchor for the brake caliper to the swingarm.









We mocked up and installed the fuel tank. The tank it is one of the few new parts of this build so far. With the tank bolted on the coil and bracket was located and installed as well as the front and rear head with the rocker boxes. This is all temporary until we get the body fab work completed then the motor will come out for the cylinder modifications.
