That looks like a good setup.  I'm going to have to start saving up.  Thanks guys, now I'm going to be in trouble with my wife again.  :rotflmao:

its a real nice setup. cheap and effective. under less than half the cost of going aftermarket and it works just the same.

Does this kit add 1 inch in length?,it looks like it in the pics. :confused:

no i dont think so. ive never actually measured it up but the carrier is in almost the exact same place as the stock carrier. i dont think you gain an inch out of it, but i could be wrong.

I shortened my swingarm 2" when I did mine. I just cut deeper into the swingarm. I didn't/don't have a plasma cutter, or even access to one. So I machined the whole thing. It took a long time.... Just make absolutely sure that the carrier is perfectly square with the rest of the arm or the bike will "pull" to one side or the other....

hey loco, just wondering how come you didnt hack all that extra shit off on the bottom of the swinger, for the old bolts and shit? get a little cleaner look and extra clearence

i should have but didnt fuck with it due to the swinger still being on the quad when i did the conversion. im doing one for "itsmyforte" and im gonna make his look cleaner.

 

bansheekid, i never used a jig. i tack one side of the carrier tube, then slide everything in and adjust from there. pull a few measurements and im done. however this one ill be doing here pretty quick wont be on the bike. i think im gonna build a jog off of it. its really not that hard to get them straight. measuring carefully can do the trick. mine always pulled straight off the line and never threw a chain so i assume they were pretty straight.

Measuring is the key.  Measure twice, cut once.  Measure three times, weld once.  .010" probably wouldn't make too much of a difference.

exactly. i dont ever weld anything up until i know its perfectly straight. its always a good idea to measure from a few different spots a few different times to ensure its good and straight. a jig is still gonna be the best way to go tho...

You guys probably already know this, but maybe someone here doesnt...

I've found one of the best ways to check if something is square is measure the hypotenuses of each right triangle. If you can nail the 2 exactly you'll have little to worry about. (basically measure front right side to rear left side, and vice versa, kinda like measuring the legs of an X )

On getting the pivot and the carrier parallel: When we weld up our swingarms, we make sure that the welding table and jig are perfectly clean, and that both the pivot and the carrier are laying flat on the surfaces.

 

And yes....measure three times, weld once. Because if you measure once, you still only weld once, but you've probably ruined the part. banghead

You take and put the bike on your flat work table. Then you take a tape and measure from the lower a-arm shock mount to your axel. you put a framing square to get an accurate measure from the front or rear of the axel. i can almost guaranty you that if you dint weld it on the bike these measurements will be off some. i really dont see how they could be perfect if you dont tack it all up on the bike. what are you guys measureing exactly? from where to where?

 

 

take that measurement and let me know how close you got it. :cheers:

 

that only would work if your arms arnt bent too.

i can see how you might doubt the process but in fact the most accurate way to get these things straight is through the use of a jig. you can pull measurements many times on a bike and if one thing isnt quite straight it will be off. i have done 2 of these conversions now and im telling you that mine pulled straight off the line. ive got full confidence that even with the swinger off the bike i can still make the carrier straight, even if i dont make a jig for it...

The most accurate way is not on the bike. Because now you are factoring in years of use on the bike, a possibly bent frame, bent anything, even just a slight tweak and it will be off. You need to measure the swinger from the front pivot tube, and square it up off of that. You need to make the swinger tubes parallel to themselves. (the pivot and the carrier). You can't measure off the front end. I do understand that this would be essentially aligning it to that particular bike, but if it's bent, it's all fucked anyways. CEJ has it nailed. You can measure several different ways, and the one he mentioned, is one that you should use as well. Also, you need to make sure that along with the tubes being in line so the bike doesn't pull left or right, you need to make sure that it doesn't sit crooked in a fashion such as when a 500# person getting into one side of a vehicle. Know what I'm sayin'??? :confused:
