just wondering what year they went from round slides to flat slides...Mark

I am pretty sure the ZRT 600's got the flatslides in 2001, they also got APV's that year. My brother had a 2000 ZRT 600 and it had the old round slide carbs but my 99 ZRT 800 has the flatslides.

I thought I saw a post here lately that said that some had them in 2000,,, I am not positive though,,,,,
