hey so this is my first post on thumpertalk. been trying to solve this for a while so I can get a couple more riding hours in before I can afford a new bike and I figured you guys could possibly help me or give me some clues to what the issue is or fixes. The bike in question is my 1999 kx80. So a day before all of these issues happened, the bike ran fine and clutch was fine. Shifting was okay. Since I got the bike shifting was kind of iffy and sometimes I would have to push the shifter two or three times to get into a certain gear. Bike isn't in the best condition and wont idle without choke on and will bog and die if it hasn't warmed up (no choke). So one day I brought it out to ride and right off the bat I could something was wrong because I tried shifting it down to first gear and it didn't make a click and felt like you were shifting to neutral (it does this to all the gears with the occasional feeling of it clicking into place but it still stays in the same gear) I rolled it and the tire would move then seize up then move and then seize up. It started up normally and I let go of the clutch lever and it was pulling very weakly and I had to give it a lot of throttle to make it move. I went up a hill and then all of a sudden the backtire seized up and the engine died and I skidded very fast to a stop. I had to drag it with the rear tire seized back to my lawn and I figured out that if I slightly moved the rear tire backwards I could "shift" I could move the shift lever and it felt like it was engaging but it did nothing. The engine still started up after that but even with the clutch lever pulled in it would act like it was still in gear and kept on trying to move forward. I put it back in the garage and brought it out and now it wont even start and just shoots a flame and makes a puff after 5-10 kicks. ive cleaned the carb really good and tried compression testing it by sticking my finger where the sparkplug screws in but instead of sucking my finger in it pushes it outwards. I don't know if it has spark but im assuming it does because ive changed the sparkplug multiple times and if I touch it while kicking I get shocked. Ive started looking into the issue today and took the clutch out and it has wear but nothing that looks like enough to cause an issue. What do you guys think the issue is?

So my bikes been making this whistling noise. It started a couple rides ago, I didn’t really know what it could be so I asked one of my friends and they said it could just be the air going through the bike or whatever making the whistle, so no big deal. Then I don’t know if it went away or I didn’t really pay attention because I don’t remember hearing it anymore after that. So I went riding today and I heard it, it was pretty loud this time, even my friends were telling me that they could hear it from quite a bit away. So any thoughts? I’ve seen that a couple other people on thumper talk were saying it happens to their two strokes and some people saying it’s normal or some people saying it could be the trans. So I’m hoping for the best and that it’s not a big deal.

Hey guys, new here. I recently bought a 08 rmz450. Pretty much stock besides stage one cam and the power flow kit by twin air. What other mods are a must for this bike. Mostly ride on my buddys land but hoping to get some track time in once I get everything dialed in. Need help with suspension settings too. Bike seems a lil tall for me considering I’m 5’6” and 140 pounds. Anyways any tips or ideas would be great. If you’ve got a rmz post pics! Like to see what my potential is with this 12 year old bike haha. Thanks. 🙂

I recently uncovered an old 1974 Ossa Phantom from my grandfathers time, I have been cleaning it up and attempting to restore it, however one of the parts I am missing is the fuel tank. What options are there in terms of putting a new tank on the bike to get it running again?

A friend of mine asked me to fix his drz125 for him. The bike was put away running and sat for about 6 years In a shed. I cleaned the carb, air box, air filter, etc... and shimed the valves. The bike will start right up 1st kick but when it gets hot it will only idle and die out when u give it gas. I think it's a fuel related issue but I don't know what else to do. Please help, any ideas are appreciated.
