So if I am running a stock 330 05 trailboss with me getting the pink spring and my bike being completely stock what will it to my max speed will I be looking at like 50 mph and will I notice a big difference in performanceand will it help me pull harder going up hills cuz mine kinda boggs down . I am planning on getting my pipe but not yet so basically will I notice a big diference just by changing out these springs.

 

You want either the EPI pink or red a K&N filter and 36t rear sprocket. This will get you up around 50mph. If you get the 36t rear the epi red works better for your bottom end. The epi pink is a good all around spring for stock but dont expect too much without other mods. Either will pull harder going up hill but thats more of a power issue. The silencer and pipe will help a good deal. Get a kit from RCR. You can get everything you need for about 325,

 

You should get a little over 50 and it wont bog down as easy on hills.
