50 cc wildfire quad smokin exhaust

got a question about my nephews quad. got it out from the winter storage in the garage. changed the oil used 10 w 40 kawasaki 4stroke oil, lubed the air filter with maxima spray on filter oil. still running the original sparkplug. when this thing is idling there is no smoke but when he is winding it out it's leaving a little trail of white smoke. not anything major but still i'm concerned. this quad has about 40 or so hours on it, is it possible that it needs new rings? also the airscrew is 1.5 turns out!!!

way over full on oil?

way over full on oil?

ed i think you may have hit it right on the head. i was not aware the oil level could make them smoke. funny when i was about to change the oil i went to the kawa shop and got the oil, then i went to the owners manual and tried to look for the oil specs, but i was assuming they wouldn't be in there. this being a chinese quad i then called the number i got off the website and talked to the supposed tech, he told me to just add till it came up to full on the dip stick. me being somewhat mechanically inclined told the guy i really didn't like what he was telling me. well i ended up doing the oil change his way since i can't read a chinese service manual, i guess shame on me. thanks for the help ed. now its time to give them another call and do another oil change!

      38MM Cast SmartCarb. Purchased a couple years ago for a yz250. Don't have the bike anymore, and it has been sitting around for about a year. Used, but in fine working condition. You can also purchase a different needle for different bikes, as well as rebuild kits from their website.
      Asking $250 shipped to continental United States. I can arrange other shipping options at the buyers expense.

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      I know this topic has been discussed in the past, but I have not found any options available for the new 2018 bikes. I live and work for a new Beta Dealer (Auburn Extreme Powersports) in California, and we are having a difficult time mapping the RR-S bikes for full FMF exhausts. We have tried contacting Beta Support several times for this issue to no avail, and we typically are given the runaround when transferring to techs and secretaries. From what we can gather, the FMF flash is designed for the RR bikes, but not the street-legal counterparts. Every time we try to install the FMF map onto an RR-S errors occur, and the programmer screen goes virtually blank. We have heard through the grapevine that some are using the RR maps on the RR-S with success, but we have yet to try it, even on our own bikes for fear that it will permanently erase or damage the CDI. Any and all help or suggestions regarding this topic would surely be appreciated! Thanks, Ben.

      This replaces the tube that connects the two carbs on a 1987 Honda XR600R (it may fit other years). 
      Made in the USA. 
      Constructed of TPU  (solvent safe plastic.)
       Its durable stiff abrasion resistant yet flexible enough you never have to worry about breaking it when you're taking apart your carbs. 
      Fits the o-ring perfectly and slips into the carb nice and tight.
      Matches the rear shock coil. 
      If you would like to buy one contact me via e-mail. They cost $20 Shipping is free (anywhere in the USA). $10 off for active duty or retired military.
