2001 Scrammy 500HO 2x4... Ive got a full after market exhaust, (loud and big, it drowns out a Harley) I dont know the brand (it was on there when I go it from the dealer) a K&N filter, and a racing clutch... I picked up a universal Altitude jet kit for the quad and I was looking for the best set up for my altitude 0-50ft (Hampton Va. area).. Im looking for jet sizes for the best performance, Im asking so I dont have to go through all the trouble shooting to find the best combo... BTW Ive searched several hundred posts and didnt find the info Im looking for, Ive only found info on changing the main to a 165, So what about the rest?

 

Most ex. systems for the scrambelr 500 only require a main jet change we change the main to a 160 adn we run a 42.5 pilot. This should get you close, you shold find out who's ex. it is they should of sen tinstructions or they shouldknwo what jets to run with it.

 

There were instrutions but every after market bolt ons (exhaust, intake) have differnt effects, elevation take an effect also, So its just a basic universal jet kit, That is trial and error for the best setup, I was just trying to help narrow the troubleshooting down to a minimum
