Thanks man.flyingfuzzball said:are you sure thats your little bro you look exactly like each other LOL
nice lookin bikes.
The XR sits 36 inches high and the KDX sits 36.4 inches high. But, the KDX sags more so it seems like it sits a tad lower than the XR. I'm 5'8" and I can touch on the balls of my feet on both. My brother is 5'9" or 5'10" and can touch flat footed on both.RM85rider123 said:whats the seat height on both bikes?
I'd say its all about how comfortable your are on a bike. If you can put one foot on the peg and lean the bike over and get one foot on the ground, you'll be fine. You probably won't be able to touch with the bike standing straight up, but for some that doesn't even matter.RM85rider123 said:thanks for the response, but since I am about 5'3 and I can fit a 34.4 inch seat height, do you think I could fit something the size of the XR? Thanks
RM85rider123 said:Also, how often do you have to change the oil that we were just talking about?
If you are running less oil in your gas, you are running a lean mixture, not rich. You are right that fouling plugs has to do with jetting, not mixture ratios, but like you said, you need to be jetted to the mix ratio you are running. If I have no idea what jets are in my bike because I bought it used, I might have to experiment with mixtures unless I want to take the carb apart and check the jets. If the plug is oily, I should rejet, but with my KDX, I just ran a leaner mixture and my plug stayed dry.2 strokes for life said:XMotoX, not to be abrasive but by putting in less oil you are giving the engine more gas making it more rich. If your bikes ever foul plugs its because of jetting not fule mixtures. I have ran 16.7:1 in one of my bikes and the results are better then that at running it at 32:1. If you are using a regular mixing oil (non-synthetic) i would not go too much past a 32:1 fule mixture. If you are running a full synthetic such as AMSOIL DOMINATOR you can run a 50:1 mixture safely and a 100:1 if properly jetted to that mix ratio. Just pitching in.
Okay. So, if my plug is black and oily, that means that I'm running too "rich" with too much gas? How does this work? You'd think the plug would be less oily if you are running too much gas and too little oil. It all seems backwards. Can you explain why? Because when I started running less oil, my plug stopped coming out wet and oily like it did when I ran 32:1.2 strokes for life said:XMotoX, so young. I once was the same way when i was new.
go there, go to tech tips on the left hand side and then go to carb tunning and go past 2 diagrams ( one of a carb abd the other of jets for slide position and there should be a big stop sign and read what it has to say.
