ROOFCOCK Posted December 6, 2003 Report Share Posted December 6, 2003 I GOT A POWER KIT W/ PIPES, REEDS,BOTTLE,SPACERS,ETC. AND IT CAME WITH 265 MAINS AND NO PILOTS.RUNNING LIKE THIS IT FOULED THE PLUGS IN A RIDE. I TOOK OFF THE LID AND ITS BETTER NOW.BUT I FEEL IT COULD BE FASTER AND I RIDE WITH A GUY WHO HAS A MODDED 400EX WHO IS REAL CLOSE TO ME. LISTENING TO YOU GUYS TALK I SHOULD BE SPANKING THAT EX AND I ALMOST THINK HE CAN TAKE ME ON A SHORT STRAIGHT. WILL I GAIN SPEED/ACCELERATION OR THROTTLE RESPONSE BY JUMPING TO SAY A 320/30 MAIN/PILOT. IT RUNS GOOD NOW BUT I WOULD THINK IT SHOULD BE BETTER. I ALSO HAVE 21CC DOMES AND A TIMING PLATE. JUST NEED THE PULLER TO INSTALL THE PLATE. I GUESS I ALWAYS HAVE TOO MUCH TO SAY SORRY. PLEASE HELP ME GET MY BRAGGIN RIGHTS BACK OH YEAH I AM AT STOCK ON THE PILOT AND PLAN TO GO PLUS 4 ON THE TIMING. THANKS Quote Link to comment Share on other sites More sharing options...
Banchetta Posted December 6, 2003 Report Share Posted December 6, 2003 One: what kind of pipes do you have/?? Two: Your riding in Va, which tells me that your running knobby tires..Shorten the swingarm -2" and get that thing to hook up. I used to have the same problem. Shortened the swingarm and its a joke to race a 400ex...Most shee riders on here that ride dunes have paddle tires which makes a world of a difference for traction and the stock swingarm is perfect for that. But w/ knobby tires, the stock swingarm is too long and defeats a lot of mods you put on since the wheels spin so much....you'll also notice a big difference in handling...Do a search and you'll find a lot of great info on this....

SDD Posted December 6, 2003 Report Share Posted December 6, 2003 Damn dude do you know where the caps lock key is? Quote Link to comment Share on other sites More sharing options...
Banchetta Posted December 6, 2003 Report Share Posted December 6, 2003 290 mains, stock pilots, raise the needles to either 4th or 5th slot from the blunt end....adjust air screws to throttle respone...I have a fireball swingarm, but I can't find them anymore.... they did a hell of a job making my swingarm. It has oval tubing instead of round or square....You can do a conversion on the stock swingarm and weld a round carrier to the stocker. Or give Gary a call at Quicksand fabs....He's cool shit and does some nice work... Quote Link to comment Share on other sites More sharing options...
