Around 90 mph.

 

90 nooooooo i have a 85 yz490 in my backyard my unk gave me 4 years back rode it for about a year and threw a rod its only a 4 speed but id say easy 80 to 85 its geard 13 50 and it could easily pull 15 40 gearing and id say it would hit 100 plus but screw that the front end is so narrow on them there scray as he!! just going 40 miles an hour im thinking of rebuilding it and trying and find a old banshee frame and see what i can do.

 

I bet it would haul in a yfz or 250r frame

 

OOH YEA lol the power is so hard rite off bottom all the way to the top i would love to cram it in a R frame or shee and gear it say 12 40 ooh man the power would be unreal [img]i/expressions/face-icon-small-happy.gif[/img] but i dont have the money to fix it its going to cost atleast 500 bucks to fix it and the money i have it going on some +4 A- ARMS AND AXLE.
