long travel rear

[revin-it02]

after doing some searching, i got nothing, but ive seen people posting up here pulling 12+ inches of travel in the rear

first question... HOW? haha (looks like at about 10 inches, the swinger will hit the airbox)

because last time i checked, my blaster is doing about 6.. not cutting it in the jumps

im trying to race GNCC again and want a good performing rear... any suggestions... elka will be thy shocks

Well the long travel setups a lot of people on here have is a lot of custom work, i cant explain it but talk to Phragle he is a member on here, and knows pretty much everything about suspension

agree that guys got it down with thoes mods and more

CAllmej75 is taking up where I left off.... he looks to be building some nice stuff.

Having a longer swingarm will give you more travel.

Having a longer swingarm will give you more travel.

not if the shock mount is moved back, or remains in the stock place.

 

[Brute71]

not if the shock mount is moved back, or remains in the stock place.

if the mount stays in the same place, the swing arm will have more travel because the end of the longer swing arm has to travel further to fully compress the shock than the stocker. The travel however wont be optimized.

If ya listen to phragle & read his posts you will make your suspension better. If you're worried bout your airbox make that the upper limit of travel. Read and follow his suspension 101( I keep sayin this cuz it seems peeps read it but don't follow it and have to do it over). You don't have to have 12" of travel but you can get a bunch more than you have now. You can find out what you get by just taking the spring off your shock. I couldn't afford a bunch of trick stuff but I got some more travel with a $20 400ex shock and a welder. I didn't get as much as was there cuz I wanted a little clearence at the bottom and didn't want an extreme chain angle at the top. And because I'm chicken If ya pay attention to phragles thread, measure like he says, it's not that hard and it's kinda fun.

Here's my variation based on the stuff I had layin around. : http://www.blasterforum.com/suspension-130/another-homemade-swingarm-24993/

Moving the shock back gave me less travel. I just took the shock, and slide a long bolt thru it where it is tucked under the swingarm. Make sure your spring is off because it's a little hard to get it compressed with your bare hands. Move the shock to a point, then measure from a point on your axle, to the bottom of the frame. Now use 2 quick clamps, or 2 regular clamps and secure it to the bottom of the swingarm. Push the swingarm fully upward til it hits the bumpstop. Now measure at that same 2 points as you did earlier. Now take those 2 measurements and subtract them. You have total travel. Not slide that bolt an inch forward, and do the same thing. the swingarm will droop a little more now, but I guarantee you will just add to the travel. I built my swingarm with a nice welder, hole saw, drill press, and chop saw. If you take your time, you can achieve this too. I'm not one on patience, but I got it all welded up now besides for the mount. I'm going to see how my ride height looks before i secure it down. One thing i didn't do before was take into account where the carrier was getting welded and it was just about a 16th off. That was enough to throw it off and make the chain not line up. Now it's all golden...but some trial and error is good because you learn much more that way. At least that's the way I am..but give it a shot! Whats the worst that could happen? Think it thoroughly before you go to cutting and welding too and draw it up. Make gussets where needed. Look at different swingarm designs from reputable companies.
