    IJSBA race legal modified class.

    What mods are you allowed to have to race in the 2-stroke modified class. I dont know how the IJSBA has it set up wether supercharged crafts are allowed to race or Non-supercharged only. I just want to know which mods can be done to a GPR so that it will be race legal in a modified class. Were im from all supercharged, stock or modified have to race in superstock. If a GPR is bored then it also has to race in superstock.
    Thanks in Advance.

    You can race it in an Open Class if it is bored. Limited is just bolt on's. It cannot be over 1299cc's as a 2-stroke. You can check out the rulebook on IJSBA.com and it will tell you all of the rules in detail
