Very sluggish on take off

Thanks to everyone for the advice and thinks whitty21.... I thought the blaster not being rejetted was kinda weird myself being a former banshee owner with mods.... but the guy i bought it from said that it has never been rejetted. I also forgot to mention that on the rebuild it was bored .20 over stock. So its bored .20 over, has a phatty exhaust, boysen power reeds and def a slipping clutch. I got a great deal on it though it has new plastics, new aluminum wheels new tires and a fresh rebuild... Just need to get rid of the sluggishness on the take off other than that it starts up and its pretty damn quick... I havent ran it on gps yet to see what it tops out at? any Idea about what top speed can be achieved from a blaster... I know when i had my raptor I out ran every blaster that ever wanted to race me but the raptor topped out at 86mph on gps.
 
Oh and btw the airfilter that was in it was sh*t... I removed it and ran it around the yard once after it quit raining today and it was alot more responsive once it could get some air but still pretty sluggish.... The carb bowl is clean... Im pretty sure once I get the clutch replace and get it jetted properly it will run much better.
 
if its not jetted, has all that stuff, and is bored .20 its shoulda blown up a long time ago. Not a jet expert, but i am thinkin a 320-330, someone correct me if i am wrong. I'm not sure about the pilot jet. this is assuming u have the air box lid off, and if u don't get it the hell off there. and a k&n of uni filter in there. Should put your bike info in your signature. It makes a lot easier for people to help you out.
 
Thanks again Whitty21.... Im new to the site too. lol. I have set up a profile yet. But i will get on that and hopefully put a pic on here too.
