I'm sorry, I didn't notice this comment and I know it's been a while since you posted it. You're probably done with the job already. The spring preload does not equal fork sag. Preload is put on the spring to achieve the right sag. Sag is how much the forks compress when you ride the bike. I'd go with what they recommend to start out with and adjust from there. I'm sure you could also call them up and ask and they would probably have a better answer than I would since it's their product. The video itself isn't really about the tuning, just how to take the forks apart and get them back together again. I'm no expert suspension tuner, but it sure is fun to learn. There's some good information on kdxrider.net if you have not been there yet, it's a whole forum dedicated to the kdx bikes. I also own the race tech suspension bible book and it's been so helpful to learn about what all the measurements mean and do. I recommend that if you're wanting to really learn how your suspension works. There's no way I can compress all that knowledge into one video or comment.

There's tons of places you can get the jets. Here's a link to rocky mountain atv that says they have them. Rocky Mountain ATV is also where I bought the whole rebuilt kit from. www.rockymountainatvmc.com/parts/mikuni-vm28-486-series-pilot-jet-p?v=1498

I assume you're talking about the wires that plug into the top of the carb. See my previous answer about that, someone else asked what that was for. It's a heater of some sort, I assume to keep ice from forming in there.

I did not do that part on mine, I couldn't find parts, so didn't mess with it. It seemed to be working fine before and I cleaned it out best I could with that part in there.

@@dirtbikeprojectchannel9143 could you get the rod out? i'm busy with an xr600r 1987 type. The rodfeels like its stuckk in there...strange thing with the locknut on top as well. Still doing studies how to get it back as good as possible.

I had to watch that part of the video to try and understand what you're talking about. I didn't put anything under the main jet. The first jet I put in is the pilot jet, followed by the main jet. The pilot jet controls the amount of fuel delivered at idle and low throttle. Is this what you were asking about?

@@dirtbikeprojectchannel9143 Thank you for replying but I figured out when you unscrew the main jet screw there is two other pieces in the little main jet I’m not sure if you took them out but one you can see sticking out if you look through the air intake to engine were the needle pushes into

@@johnmxboi7024 yes he missed cleaning those important pieces.

Luckily I found out I don't need surgery, so I hope to be back for maybe the race in August. I can't decide if that stump/roots got me or if the suspension just bottomed and sent me in a weird direction, but either way, bad luck hitting the tree. I need new footpegs. I finally got a chance to look at the bike and the peg is bent back pretty far. See you at the races!

It goes to a 2000 TTR 90 dirt bike. If you're asking for the brand or model number, I've sold the bike, so I can't look to double check.

Mikuni I’m pretty sure Yamaha would use there carbs a lot I’m not sure if they use them and more but it’s a mikuni

The two wires go to a heater. If you look at the OEM parts diagrams(I found it in the electrical harness diagram, not the carburetor diagram), this is what it's called. I can only assume this is to keep the carburetor from icing up, I can't think of any other reason there would be a heater in there. When air goes through a venturi, the pressure goes down, and the air speeds up. This is how the carburetor is able to pick up fuel from the float bowl. The air also goes down in temperature. The air can get down to a temperature where the humidity in the air condenses and freezes, causing ice to build up in there. I fly airplanes too and on carbureted airplanes you have to turn carburetor heat on and off to prevent ice build up during different phases of flight. I've never seen a carburetor heater on any other bike besides this one. I've read online a bunch of comments from people saying they unplugged it and they had no issues, but I never tried it. I hope this answers your question.

@Get at it, I’m guessing you have an aftermarket carb on your Bike, not the OEM carb. I believe the aftermarket carbs don’t have the heater assembly attached. Like Ryan stated, It is used to warm up the fuel in colder temps giving a better idle and throttle response.

So the aftermarket carb with no heater is a perfect direct fit with no issues??
