those jets would be close at sea level if its not to hot and your oil mix is 32:1 but i would go down 1 on the clip and check the floats, make shure you dont cover the hole in the slides with the retaner. and make shure the slides are in the right carbs the 45 should face rear of bike. plus i found that fattys and big porting dont go all that well together. porting gets u the high rpm and fattys are a low rpm pipe. cpi or some other hi rpm pipe would do better your parts need to match ur motor

well anybody will tell u that advanceing the timing will help. what are you at sea leval 1000-2000-3000 ft droping the clip down to the forth grove should help your mid range if your not to fat on your main. but you need to nail the main down first. you need to search this site more. find the plug chop.
