    How not to get screwed when buying dirt bike?

    Is piston slap the same thing as an engine knock, or at least one thing that can cause an engine knock? Thanks no, its not an engine knock. Piston slap is a loud slap noise from the piston in the cylinder slapping against the cylinder wall when revved depending on how bad the rings, cylinder ports and piston are worn. The worse the wear the louder the slap noise will be. Extremely worn will be very loud when revved. I don't know how to give you an example of what it sounds like but it might sound like hitting 2 aluminum cans together real fast. rev it and listen at the cylinder. it will be a very noisy sound when revved. Probably wont hear when at idle. heres something from you tube. maybe it will help. https://www.youtube.com/results?search_query=2+stroke+piston+slap+sound+

    How not to get screwed when buying dirt bike?

    Adric, i only read the first page of replies so i dont know if the idea of piston slap was suggested when inspecting any 2stroke. 2strokes dont have a long ring life. They make great dirt bikes because of their light weight and power for their size and weight. 2 strokes wear at the ports and get what is called piston slap when the rings, ports and cylinder are worn. Rev it and listen for piston slap noise. If it has slap and you get it cheap it might be worth it. A new top end is needed. on a 4stroke i look at the oil, intake, exhaust ports and engine casing seals and gaskets for signs of oil leaks and consumption. if it's real clean i would be suspicious of consumption and oil leaks.

    Hard starting when warm

    i had a bike that had the same problem. started cold ok, but would not restart when running for awhile. it was way too lean, running hot and the header pipe turned blue. 1.. did u do a plug check? 2. is the pipe turning colors like a blue at the header? 3.. does it have unstable idle always adjusting the idle?
  6. yeah, i was goin' with the same idea. i have seen videos of bikes going off road into a river past the engine but the bike was insulated and had a snorkel. 1. will it or will it not high pressure washing, soap and water will get into all the electrical connections and cause problems? 2. doesnt the electrical need to be insulated for pressure washing and submersion in water?

    Exhaust and air box mods

    even motorcycles are falling under EPA smog. I just wanted to bring to your attention to ask before you modify, remove the airbox and change thiings.

    Exhaust and air box mods

    just asking. what year is it and does have any smog on it? if you take the smog controls off, and remove the airbox it wont be street legal anymore.

    Honda xl / xr advice needed ASAP!

    i got the Q. Doesn't matter. I had a 75 XL175. its a great bike for off road and trails. its not anything like a YZ but thats ok. buy it and ride it was my point.

    Honda xl / xr advice needed ASAP!

    i had a 75 honda xl175 way back. It was a great trail rider, low rpm, easy to work on and low maintanance. Check it out real good. Listen to the valves, timing chain and run it through the gears. Run the plates and vin through DMV. If it's good and evrything works buy it.

    250 jetting question

    your having a lot of probs with that carb. look it over good and make sure it clean. maybe get a new float needle valve. if its a CV carb look at the rubber diaphram in the slide., it might have a hole in it.

    250 jetting question

    so whats goin on? have you had time to work on it? what are the final jets you settled on?

    YZ250 Jetting catastrophe

    just a suggestion. did you do rebuild kit on the carb and replace the float needle valve. is it leaking fuel out the bowl area? they leak and overflow making a rich mixture. it cant be fixed. the seat is worn out. messing with the float level is a waste of time. at 6500ft factory jetting will be too rich.

    4 Stroke maintenance costs ?

    if you want a low maintance bike for off road mountain and trail riding get a low RPM 4cycle that has been maintained in nice condition. if you want to go fast and hotdog jumps get a YZ or something like it.

    250 jetting question

    no i dont know what the original factory jets were. i would use that as a starting point because factory jetting is usually not good and very lean. try and keep the needle in the middle so it will give an option of lean or go more rich in either direction. you might need to change the needle to a smaller tapper and use washers to raise/lower because they usually dont have notches. the factory needles have a wide tapper. not good for mods and better jetting. do a search on the year of that bike and see what comes up. heres a link. https://www.google.com/search?rlz=1C1OKWM_enUS777US777&ei=hFHKWsGsPNGusAXyiZg4&q=dr+250+factory+jetting&oq=dr+250+factory+jetting&gs_l=psy-ab.3...22294.22294.0.23346.
