wow wow wow with the 225 main jet! your gonna blow that sucker up especially if its ported. heres what i would do... send your cylinders to a site sponsor to get ported to make it do what you want or keep it stock. i would runs pods but if your hard on using the air box then take the lid off, throw in a k&n clamp on airfilter with the adapter, throw some 27.5 pilots and 280 mains in the carbs ( if it is NOT ported) ( if its ported you will be in the 300+ range), get an adjustable timing plate and put it at +4. run stock needle in middle position. im taking it that you are below 2000ft above sea level also so your elevation and temp with effect jetting. also note that when you jet for summer you will need to rejet for winter with bigger jets. learn to use the search function and you will see alot of set ups and jet they use
