hey I hope someone out there can help me i just purchased a new quadrunner 250 and i am really disapointed in the power of the bottom end i cant even top 25mph up any gravel road hill except really short ones in low range it has plenty of power but top speed is 10mph i have checked plug,using good gas,clean filter it has been like this since i bought it any suggestions would be nice thanks everyone perhaps it needs bigger jet how many sizes smaller or bigger help is appreciated. buckslayer82@hotmail.com

 

The Quad runner,along with its bigger brother,the 280cc KQ,are both underpowered quads,though,they are both extremly dependable quads.Are you saying the quad only tops out at 25mph in high range?It should have a top end speed of around 42mph on flat land in high range.It will take awhile to acheive that speed though.If not,you certainly have a problem and I'd suggest getting it back into the dealership under warrenty for a complete observation.===Bill

 

I too have recently purchased a 2000 quadrunner 250 4x4 and in comparison to the 1999 that I bought last year for my wife was very disappointed in the performance and when hot hard trouble with it starting. I returned it to the dealer in Helena Mt and he contacted suzuki for recomendations. Seems the new carb on the 2000 hasn't been set-up properly. He jetted down the carb main jet, adjusted the air screw, installed a colder spark plug, modified the crank case to air box breather tube and installed the cooling fan. WOW!! what a difference this thing feels unbelievable- pulls the grades 5% in 4-5 gear high range and tops out at 50+. I thought the 99 had good power this 2000 is even better.

 

thanks everyone for helping me so quick and also if you could send me more details about how they fixed the problem at the dealer it would be nice so I now what to tell the dealer I bought mine frome Thanks again skyler
