What do i have to do to keep up to my dads magnum?????

I already have it

40 over
racing reeds
K&N
EBS clutches

thanks

 

it is either way out of tune by the way you have the carb jetted or it is ready for another rebuild.a stock 400 xplorer will dust a 500 magnum.i had no trouble dusting my friends 500 ho with my 400xplorer and it was stock.

 

I would agree,
I have often seen Explorers outrun the 500s, and sometimes the 500 HOs.
If the motor is fairly fresh, you probably need to rejet the carb.
Start with a simple new plug and filter, then get the main jet and needle clip setting dialed in. You obviously have "Tuning Issues"
Good luck

 

Do you have oversized tires? They will shave a good 5mph from your top speed.

The EBS clutches will also shave a little off of your top speed I have heard.

As MegaCrash indicated, the first thing to do is dial in you carburetor. Before you tear it all apart try tweaking the air screw in 1/8th turn increments. This can make a 5mph difference on the top end when dialed in right. Good luck. [img]i/expressions/face-icon-small-smile.gif[/img]
