Hey guys love the website. Been doing a lot of research here so decided to post up my build. The bike started out as someone else's project that had a lot of nice parts. I sold most of them and started to rebuild it to my specs. Running a ct 370 engine with a Roll front end. The rear is setup for a custom built 18" axis shock. I built a new upper shock mount and modified a +2 lone star swinger. Still have a lot of work to do. A lot of things are still in mock up but this is what it looks like as of now. Plan is to ride it on New Years.

Dannnnggg ! Please keep us updated on this build
-
Looks great, what's the plans for plastics?
-
Looks like a zilla boot off the carb. Seems to be a lil adapter in-between.
-
:popcorn: Damn this looks bad ass...i have to see this
-
Ok talk to us about the rear shock mount modifications, looks like you fabbed up completely new mounts on the frame and swingarm. Your shock angle definitely doesn't resemble a no-link
Awesome looking build so far
-
What do you me resemble a no link? I'm not sure why others run such an extreme shock angle. At full bump the shock should be at 90 degrees to the pivot point. Otherwise the shock is to big imo. And you are not getting any better performance laying it down. With my setup the angle increases slightly as the suspension compresses. Adjustable upper and lower mounts would nice though.
-

I have white plastics and a carbon fiber hood. Also should have the wheels and tires done in a week or so

I just meant the shock isn't at such a severe angle like on mine. I like the way you did it, makes it much easier to use a standard air-box
-
The airbox is pushed back pretty far. Just over the seat latch lol. Will have to do something so I can get to those pins. The zilla boot worked perfectly for me. I definetly got that idea from here. Would way rather relocate the airbox then have to build that part.
-
How much wheel travel will you have? Laying the shock over by mounting it towards the rear of the swing arm allows you to gain ground clearance. Not having anything hanging below the swing arm helps us woods riders.
I'm just jealous you get to keep your airbox without modifying it. Looks good!
-
Very nice build bud. I love that your doing your own fab work. Wish I had the knowledge and tools to do so myself. What airbox are you using? I have a stock right now for my build but like the look of the one your using.
-
Very nice. What radiator did you use?
-
It has about 12" to the bump stop. Nothing crazy just some good usable travel but thats another reason adjustable mounts would be cool to have.
-
Cfm airbox from eBay. Really nice box for the price
Afco radiator
-
The more vertical the rear shock the better. This resembles a Cr500 linkage or any modern dirtbike rear shock set up.
-
Killing me with them AN fittings! Super clean!
-
Well didn't make my deadline. Trying not to rush this but I only get maybe an hour a week to work on it. I put the plastics and wheels on to see what it will look like. Just need to find time between other projects and work to finish.

And my Duncan/Roll banshee I'm rebuilding for the tenth time. I have another one that I built with a custom front end and is going a compete different route. So this one is going back to how it was before. With a fresh look.

Both bikes look great! What front tires are you running on your R?

Thanks man. They are 22/7/10 maxxis razor. Had them buffed into a Mohawk for the dunes. Wanted something a little bigger and stronger then what's offered. So that's what I came up with.
Rear wheels also custom made at 5" wide. Gives the paddles a little more bite in the sand.
-
Bro I absolutely love what you've done with both quads especially the R. CUSTOM NO LINK mount looks great. The white plastics and carbon parts are sick with the beadlocks all black wheels. And cut front razors is something I haven't seen before. Genius man. That R is one sweet quad. Congrats
-
Just a question on your no link set-up.... Did you slow the rebound down on your shock?....I would think you would have to at the angle your running it at to calm the pogo effect.... By having the shock angled the rebound tends to push forward on the quad more than up....That being said if you have the rebound dialed you should get some awesome traction as well as not having to run as stiff of a spring.... Keep this updated I'm really curious as to how this works for you...Awesome build by the way!
-
Looks great!!
Do you have an air scoop for the right side of the radiator? How tough is it to remove the keepers for the seat pins?
-
SO-CAL guys are bad ass fabricators. Keep it it bro looks amazing.

Nice - they look killer and like you say, probably get a bit more carcass thickness. At first glance I thought they were Cascade Innovations "Cutters" http://www.cascadeinnovations.net/store/store_View.cfm?STORE_AREA_ID=12&store_dept_id=72 (http://www.cascadeinnovations.net/store/store_View.cfm?STORE_AREA_ID=12&store_dept_id=72)

Thanks!! I saw yours it's just as nice. My next build will be all red with 89 plastics. Was the original plan.

Never heard of the pogo effect but I can control the rebound simply by adjusting it. And the shock angle has nothing to do with rebound. You may be thinking if the effects of a rising rate shock setup. IMO it's never a good idea to lay the shock past ninety degrees at full bump. In this case the swing arm pivot bolt. That way it cycles in the same path as the swing arm. Making the shock work most efficiently. Just because Honda mounted the shock the way they did 30 years ago for clearance issues. Doesn't mean it's the best. This is how I mount shocks on all my builds. Although they are mostly long travel A-arm and 3-4 link type suspension on trucks. This should be no different. It's just how things have worked for me in the past.

Yea it's just sitting on the shelf. I have a few other parts still to put on I just wanted to see what it looked like with the plastics on. I will post some better pics once the bike is done.
Its easy to pull the pins under the seat. That worked out perfectly.

Haha right on thanks. I try!

Ahh indeed. I didn't see those. The 8"'wide would have been the deal breaker for me. Also wanted 4 ply tires.

Mind me asking what it cost to get a pair of tires buffed like you did?
-
If I remember correctly smooth buff cost $60 a tire. Told them to leave the center tread and buff to the wheel. Not something I have seen before so I'm really happy with how they turned out. Exactly what I wanted. Lots of ground clearance on this bike.

Thanks for your explanation and answer... I noted an annoyed tone in your answer..and I apologize.. My question was out of curiosity and not harassment...

Oh my bad not at all annoyed. I'm sorry it sounded that way. Actually your question is completely valid. I understand my setup is different then others that's why I posted it here. So in reality thanks for asking! Gives me the chance to explain why I did it this way. I didn't think people would really care to hear about the shock angle specs. But I didn't just randomly weld in some shock mounts and hope for the best lol. It's just my perspective on things from experience. So again thanks for asking I have no problem answering any questions. This is what I love to do!

Builds look amazing with good taste. Nice job. Love the way they look.
-
Looks crazy awesome and I bet she's a rocket! What kind of handle bars are those and what style bend?
-
Very well thought out build
-

Renthal midsize for something like a cr80. Using a +1 stem. Right at shoulder width for me.
Thanks for the compliments guys

looks great. builds are the most fun when u do the fab work yourself. keep us updated!

Have a few small updates. Mounted a coolant tank. These are a must have in the desert. The extra capacity won't hurt either.

Each side has a cable guide. Also covers the afterthought welds and burnt powder coat.

Very nice who made the tank?
-
Not sure. Cost $50 from a hot rod shop down the street. Might have been used.
-
Nice use of space. I have a question, is that the filler cap for the whole coolant system. Or is it just a overflow reservoir.
-
Just the reservoir fill cap. Needs a window or something to check the fluid level. Will have to figure that out later.
-
Nice work SD. It would have to be an overflow/expansion reservoir seems it's lower than the top of radiator.
-
Yea. It works from pressure so it doesn't really matter where it's mounted.

That's why I asked.

Look at go kart stuff they have similar set up. They use a clear hose running vertically with a 90 degree fitting at the bottom and top tapped into reservoir. U can see the fluid level at a quick glance.
-
Yea I thought of that. Definetly the best option. I guess for now I will just stick my finger in there between rides and make sure it's about 3/4 full. Lol

Did this bike ever get finished?

I would like to say that it was but the original poster hasn’t been on the forum in 7 years
