Ok, so since I was in a hurry to get my 500 running and rolling, I only installed the fronts. I was putting around the neighborhood all week, breaking the engine in. Well today I decided to let er rip. First a little tec info. Slow jetting is off somehow and I have to give it about 1/4 throttle for it to bust off and about 1/8 to keep it running and ideling. Its doggy down low, but main jetting feels right on. Now on with the story. I went to the end of the street, turn around and hit it, it bogs but I stay in it, and about the time it clears up, the engine gets up on the pipe and up comes the front end, no biggie, ill tap the rears and bring her down, wait, where are the rear brakes?, OH $H!T!! After getting my head around the fact that I have no rears and im still pointing skyward I decide to gear down and drop the clutch, but in the meantime I have been bearing down a brick mailbox. I decide to bail off the back and better for the quad to hit than me and the quad. BOOM!! Quad does a flip and lands on its side, handlebars are bend down, clutch perch is broke and right rear tire is off the bead. Aint this some $h1t, I push her home and walk over and tell the neighbors about thier mailbox. Luckily it was my best friends parents house and they laughed it off.


Now on to the jetting. Stock cyl and compression 87 Zilla, LRD pipe, 39.5 carb. Its real boggy down low, but cleans up once it gets up on the pipe and the main. Engine passed a leakdown test and is not sucking air. Sounds like the slow jet is to small right? Jetting is 50/175. I cant help but feel that this is plenty. Any thoughts?


WANTED: Complete rear break setup for lt500. I have the pedal and rotor, need everything else.

 

sorry about the zilla but i would have loved to see that.

 

I would adjust the air/fuel screw first,and the idle screw if that don't clear it up then spend the $ on a bigger piolet jet.Oh you was'nt by chance riding with the choke on were ya?
