I can only get 57mph no matter what I do to the atv it will get there really fast but just will not go over 57mph and I only 170 pounds!! The belt is so tight it squeels at idle, i have the snorkle, 142,145 jets needls shimmed .055tho and the muffler mod, what gives?? I can wheelie it no problem plugs are fine what can i do to get more top speed, I have 26in mud lites, my elevation is 800 feet.

 

mid 50's now befoer I did any thing to the bike I got mid 60's by thr way if you mean big people try this one 380 pounds[img]i/expressions/face-icon-small-happy.gif[/img]

 

I have a winch, bearclaws, and my 02 will tops out at 62 mph. It get's to 57 fast but the last 5 are very gradual.

 

i have a winch, rack bag, 26" mudlites, <u>no</u> motor mods and i can still get to 60 mph.

 

Bone stock w/winch and 62mph. Not much air up where I am either. It does take some road to finally hit top speed, but high 50's quickly even uphill. Check your speed w/a GPS, maybe your speedo is off. Also do some plug readings or hook up an A/F meter to see if you're carbed right. When I first bought mine I was having some staring/stalling issues. The shop decide I was running rich and leaned me out. It was gutless and I lost 10mph so I had them switch it back. I think I'm still a little lean as I get backfires through the carbs if I pull the airbox lid to get some extra air in. Anyway, the Kawi elevation chart is usually lean for emissions to start with.

 

I am 6'4 and 320 and I have had mine up to 64MPH. It was a long straight away but I also ran out of room. She had some more left. My prairie has had nothing to the clutch or engine.

 

Guy's no two bikes run the same AND I don't think any two speedometer's are the same, get someone with another 650 and run them at a certain speed and compare speedometer's, you may be going faster than you are showing, mine top's out higher than most but lower than some, when it was bone stock it would do 62mph, I added the HMF, dyno-jet, and airfilter and it went to 66 mph, I later put the EPI red/black clutch spring's in and top speed is now is 64-65 mph.......
