Lined up the atv's today. My brother was on the grizzly I was on my bike. The grizzly is jetted and normal sized tires. My specs are in my sig. still yet to put my jet kit in and get it tuned right.. They are almost identical in speed when we go side by side this time we went by times.grizzly ran a 9.43 I ran a 9.5. Bogged alittle on the start. Oh well once I put the right jets in and tune it it should be good to go. enjoy... Grizzly... Blaster..
