Picture is worth a thousand words! lol he has a strut on the rear. The bar is a single tube going up. no braces or anything. the wheel sits anywhere from 3-6 inchs off the ground depending where he has it set. chromoloy for the bar I think. the bar is like 5ft. he needs a longer swing arm Quote
Joejr915 Posted May 25, 2011 Author Report Posted May 25, 2011 I got marvins in the front and it a 3 bar wheelie bar with a gokart tire on the back. The bar is about 6in off the gound. Quote
n2otoofast4u Posted May 25, 2011 Report Posted May 25, 2011 (edited) Golf cart tire? I'm not sure what your power plant is, but the 6 over arm is probably a bit shy. You can mask some of that with bar design. IMO, your bar is to short, I would make it closer to 7' and a 4 bar system. If a bar is rigid it will do just as your describing. It's gotta be able to flex a little and absorb some of the impact. Also your tire is too far off the ground especially with it being that short, a pop can height is a good place to start, maybe lower if you keep that super short bar. Also be sure that your Marvin arent pushing up when you are staged, they will just increase how fast its gonna come up. And lastly, run little air in your tire so it also can absorb some of the hit.Again this is all just my opinion and as most will tell you, I don't know shit Edited May 25, 2011 by n2otoofast4u Quote
J-Madd Posted May 25, 2011 Report Posted May 25, 2011 I like the bar to be about the same length as the wheelbase on a ridgid. On a strutted stock chassis I think I ran about a 6' bar, but with a +8 swingarm. On the stocker, I'd ride up towards the tank and it would pick up the front and carry it for over half track (if not over 200 ft). Quote
