So I check my notes and piston is 20h, not 10 so I took it out yesterday. Whats your thought about the plug? Some tips above was to use larger jets. Is the plug also telling that? (As I see its darkbrow/almost black)

And Piston ring clearly ... more »

Nice! Must have been more power on those old kx:s to pull such Andrew Short starts

Cant test anything this weekend becasue we will be in Uddevalla to watch the MXGP racing. Will be nice for sure.

Yes, more clutch sensivity is most likely the key in this matter.

ok, I checked that and it looks stabil, but thanks for the tip.

Hi, yes is possible, it seems like this both on practis and at the last race as well //Mikael

I was so sure it was the bike that I did not fully take rider factor into the equation. He thinks and I observe that it looks like he does similar starts and after 3-4 bikes start to bog, Neither the -14 kx nor the earlier KTMSX65 -13 acted like this...

I dont think I will change front sprocket, maybe add 1 tooth to the back, at the most. actualy on sandy tracks you can drop 1 to run longer on the same gear thru the whole berm not needing to put in the next one in the corner so to speak, I think my ... more »

thanks for all the tips! It happen like this also before the change of piston. Regarding the Power-valve: When I changed piston I basicly remove the locking clips from the axel and then slide the other "arm" of the axel to the side to get free clearence ... more »

Yepp, you are right, its a cheap test to do. My only concern is that he would end up between 2:nd and 3:d gear in some turns. And as you wrote good (experianced) riders could adapt, but my son is not superexperienced and is not a big fan of feathering

1 tooth on front sprocket will change a lot on the all around handling of the bike on the track. My son seem to be pretty satisfied with the stock gearing on most tracks for his current speed.

I was thinking about the needle aswell, drop the needle (raise the clip) will give less fuel, maybe that will help. I need to test it Kawasaki actualy also provided a additional needle when I bought the bike, I did not check if it is thinner or thicker ... more »

That would most likely help, im only frustrated it varies, sometimes it seems allright and sometimes it bogs. I dont recall his last bike kx85 -14 acted in the same way.
