I know the 88+ carb is more desireable than the 87, i just dont know why. What are the differances between the two. I know main and pilot jets are different but what can i do or change on my carb to perform like the 88+ carbs. Mine does alright ,starts easy enough and idles well but if there is room for improvement im all for it. Also is there a needle close to the stock 87 needle that will perform similar mine is worn out and I cant find a replacement.(only availabe through suzuki?) Any help would be great.
