450r swingarm question

I recently bought my first 450r from a buddy of mine :D its a 2005 with a JD widening kit(i think thats the brand), pro circuit full exhaust, jet kit, k&n filter, outerwear, ITP rims, front bumber, AC six pack rack, custom seat, and i think its +4 on the swingarm. Would the swingarm give me trouble at an mx track? im definitely going to take off the lowering/widening kit

still no help? :/

JMO, if I were tracking this beast, I opt to go without it, but I believe you will be fine either way....it just comes down to how it feels for you.

Yeah it would definitely help if you switched it for a stock one but i think you will fine at the track until you do, it will probably just handle a little weird. But since you plan on MXing it i would look for a stock swing arm as soon as you can, or a aftermarket one like Houser or JD.
