Moderator Cynic Posted May 18, 2015 Moderator Share Posted May 18, 2015 Cos its a yz80. Its what they do. Subtle and smooth are not used to describe a yz. 1 Link to comment Share on other sites More sharing options...
GREIGE Posted May 18, 2015 Share Posted May 18, 2015 Hmmmm... This is me talking straight off the bat. No guarantee anything I write is fact or useful. Because its such a small engine you may need to slip the clutch a bit more than you think to get a smoother pull away. Or it may be as Cynic says and its just a trait of that type of bike. But try slipping the clutch a wee bit more first. It will really annoy the neighbours....... 1 Link to comment Share on other sites More sharing options...
Moderator Cynic Posted May 18, 2015 Moderator Share Posted May 18, 2015 Neighbours. Its a mx bike. Full blood rip your nuts off leave your brains at the start line mx. It will rev to maybe 12000rpm and make cock all power till 9. Below 5 prob wont even pull away. It is meant to spend its entire life either on or spinning the rear wheel.

fabiostar Posted May 19, 2015 Share Posted May 19, 2015 as above . you could try dropping the needle one notch as it sounds like its running rich at the bottom end and bogging the motor. check your reeds and make sure they are closing as with use they can get lazy in old age aswell Link to comment Share on other sites More sharing options...
