How fast have you had your ATV?

Recommended Posts

Calling you out on this... What tires, gearing, and RPM were you pulling to make this happen?

20inch box tires, geared down on the rear sprocket and up on the front sprocket. a good friend of mine is a sheriff and clocked me on several runs, 119 was as fast as i could get it.

Going down or up 1 tooth on the front sprocket would be equivalent to going up or down 3 teeth on the rear.

I do hope you understand your motor would have to rev up to 13,100rpm to reach that high of speeds with that gearing ratio.................

yes IF i ran those ratios of course, i went down like 8 teeth on the rear and up 2 on the front. It's not like 2 strokes are hard to get more revs out of anyway...

the max rpm's for a bone stock banshee is 9000. But it all depends on your modofcations. Banshee's with the power valves like the 421 cheetah's will rev up to 18000 RPM"s

No. A 421 with Cheetah cylinders wont touch 14k let alone 18k... Either way, it's not possible.

since you do not seem to understand, iLL TAKE YOU TO SCHOOL...

i ran a 16 tooth front sprocket

i ran a 30 tooth rear sprocket

this gives you a 1.875 ratio with 20'' rear tires

the banshee's Primary Gear is 2.869 this is at 10,000 r.p.m's for a built banshee.

Yamaha banshee Gear ratios are as follows

1.st gear ratio is 2.461

2ed.gear ratio is 1.812

3erd. gear ratios is 1.500

4th. gear ratios is 1.250

5th. gear ratio is 1.045

6th. gear ratio is 0.875

so technically speaking it would run 126 mph, this minus the tire friction and wind speeds produced there for i ran 119 mph and not the full 126.

Just tell her you were being chased by a swarm of bees and it was the only way to not get stung.

Anytime I come back from a ride with no broken bones and/or blood loss my wife is usually happy with me.

Talking about speed my daughter was riding my prairie 650 and her sometimes friend wanted to race with her Honda 250 rincon. My daughter was smart enough not to race. I think God she listen when I said be careful and don't do anything stupid. If the friend wants to know how bad an old 650 is me and her dad can drag'em and she can watch from the sidelines.

I've had a yamaha grizzly 660 up to about 60 and had a friend king quad 700 up to about 70.  For sport utility quads, that's pretty fast I think and not really going to do that in the woods or on trails. It's pretty impressive some of the speeds these sports quads are getting up to . Here's a fast as hell banshee..

      got 7 atvs off CL recently for a good price.  one of which is a yamaha warrior.  anyone know where the vin is printed on this bike?  Haha good place to start as I do not know year or size yet.  The former owner says needs exhaust ans and clutch work.  he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears.  things I see:  clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box.  I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first.  also, battery (looks brand new, what a shame) is dead, 0 volts.  Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last).  any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
      the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like.  lol I'm spoiled on my automatic polaris

      i have a 1993 timberwolf yamaha and the compression is good and lights work but for some reason the electricity is not going to the spark plug(s)! i got a friend to check it out and they said its no use but im not giving up! please help with this!

      I have a 1988 300 Honda FourTrax, All wheel drive.
      My brother and I were fixing up this quad. We put a brand new battery and fuses in and it was running fine until we put the quad into reverse. As soon as it was put into reverse all of the electrical cut out and power wasn't making it to the head unit anymore and both of the brand new fuses popped. We figured there might have been a short from the starter or solenoids, but they are all working properly. At this point we don't know where to start looking for where the short could be. I'm just wondering if anybody has had the same issue or knows of similar issues that could cause these electrical shorts?

      Not satisfied with the commercially available versions, Jonathan recently built an ATV spring compressor.
      In this video, he demonstrates using it to remove & re-install the spring on an ATV coil-over shock absorber.
      Mistake in video - the coil-over shock is not quite a McPherson strut.
      If you are inspired to build your own spring compressor, feel welcome to use any ideas from this video.
      Thanks for watching! Resurgence Small Engine Inc.
