    my locking screw that is next to my flower nut is stuck and it will not come out.. i tried like ten different big and small screw drivers and started to strip it so i had to stop.. i need to adjust my flower nut or get new pads and without that screw coming off i can not get at the pads. my clutch slips while i ride like it is not fully engaging i think ... when i let my clutch handle all the way out..

    when i let the clutch handle out to drive it.. i hear zzezzissp and then it sometimes catchs and stops but the fact it that it is making me go really slow .. like i have to peddle the bike faster just to get the thing to go quicker then the bike is is supposed to go.. my motor used to go so fast that no matter how quick i peddled it would not move the bike quicker then the engine was going... i need help and hints or tips on how to fix this problem.. have you ever had this problem before

    You might try using the best fitting screwdriver then tapping on it with a hammer. Don't beat it to death just give it a few sharp raps with the hammer. Sometimes that will help break a seized thread. If that doesn't work you might have to resort to drilling the head off of the screw. If you have to do that then try to leave enough thread to grab with needle nose pliers or vice grips. A replacement screw shouldn't be hard to find at a good hardware or auto parts store. Good luck. Let us know how you do.

    Here is what you may try. I have used this method and it always worked, plus it will break down any loctite that may have been used. Take a soldering iron and heat it up as hot as you dare. Then place the end of the solding iron onto the screw's head. Hold it as long as you can transferring the heat into the screw. Wait awhile and then try it, as rough as you are permitted. If this not work, repeat the job again. If you heat it many times, you should be able to take it out with your finger nail. One thing I would replace the screw with a new one.

    The soldering iron trick should work. I have used it a few times with success.

    I have always tried a few taps of a screw driver on one edge of the screw, going counter clockwise, if not then cutting a new slot to do the same. I've never heard of the soldering tip method, but I will try that on my next mishaps so thanx to you guys.

    A little penetrating oil works wonders sometimes too.

    Depends what you mean by "extra oil". You shouldn't have to add extra, just the normal mixture of about 40:1.

    I use the heat method with a tiny pencil torch to cook off the loktite or varnish, then I found I can use a small driver tip in my hand impact hammer. One or to taps and then the screw turns normally. But replace the screw and loktite if needed. I found that on carb screws a drop of the wife's nail polish makes a good varnish that is easy to break loose later if needed for adjustment.

    Seriously? You ran five tanks of straight gasoline?!? It is more than likely roasted...stick a fork in it to see if it is done, I suspect it is.

    You realize this is a 2 STROKE right? This means you need to mix oil and gas together, otherwise you don't have any lubrication. No wonder your engine isn't running right. You ruined it putting straight gas in there... I'm amazed you were able to make it 5 tanks. But you need a new engine. This time, mix the oil...something like 24:1 for break in and 32:1 or 40:1 afterwards.

    haha i didnt ruin the engine... it is still running but want to check the clutch plate and see if i need new pads .. going through the snow at a really slow speed but super high rpms didnt help either... i already have a raw motor coming and a brand new bike.. get it this morning.. will race the two against each other to see how slow the old one really is going.... but it did lose power from the no oil thing.. these motors are so cheap i dont beating on them some... got a full year of transportation out of it for 220 bucks.. so i cant complain but you can bet that i am going to fix this old beat up motor back up... get better high rpm bearings and new clutch pads and tap the broken motor mount screw back out... have been riding with only the front motor mount for about five months..
    yes i do drive it everysingle day.. and have had a wetlockz exhaust ran to it.. which is a box with a one way valve so the exhaust fumes go through the water to make it quieter.. only if i could design something like that for the intake noise... i need to get that quieter... any ideas?

    gonna keep the new one clean.. and try not to beat it...lol.. wont be cheap or forget the oil on this one..

    I'm sure we're all pretty sure that you don't have a clue about what you are
    doing.
    Anybody that would run a 2 stroke motor with no oil premixed in the gas and then bother to think that they will be adding performance parts to it afterwards
    needs a lesson in thinking clearly. Especially 5 tanks of gas.
    I'm not going to lecture you, but at the same time don't think you deserve help fixing something you more or less intentionally destroyed.
    Good luck to you and I hope you don't work on your own car!

    This story is strange to say the least. A while back, I got cheap and switched from Red Line Synthetic oil to regular air cooled two stroke oil. Wiped the cylinder plating in one ride on my R460. I can't imagine a China Girl, run without any oil, not seizing solid.

    i am sorry to tell you kerf but no i do not lie and what you guys are forgeting is that our tanks do not go completly empty when we fill them up.. yes even if you cant start the bike.. there is still gas in the tank. so i had some oil in the gas , the little bit that was left in the tank. but no i didnt add oil and yes i did it like that for two straight tanks. my bike is fine and runs ok. it has close to 1700 miles on it easily.

    as far as it goes for timboeller... just because someone is careless does not mean they dont know what they are doing. i know what i am doing and the only reason i asked the question on here about the stuck screw is because it did happen to me and i had to go in the garage and get the tool. i did my first motor change in a car when i was thirteen . so yeah thanks for the input of your two cents.. which does not add up to anything with your negativity. sorry to inform you but if you dont have anything nice to say or to help out , then why bother on here? go take your wasted time else where. we dont need individuals like you roaming around here bored and looking for ways to be spiteful.
    as far as intentionally destroyed, i did not. i did not have the money for the oil , or was not near somewhere to buy the oil, or the stores did not carry it in stock. who cares the reason? point is that i have ran these motors like that and it was from bikeberry.com. so i say they stand up to a pretty good beating. AND JUST SO YOU KNOW, EVERYONE ON HERE DESERVES HELP FIXING THEIR MB. that is another thing that makes us stand out as good people and not like the rest of the scum like all the other whatever clubs....
    thats my take on it ...

    Never said you were telling a lie, just that the story was strange. If you didn't destroy that motor, you're very, very lucky.

    vista man i do know i need to add oil. i just was not able to at that moment . times were really tough for me at that point in life. we do what we can to get by. just so you guys know i have also ran crisco oil in it before... yes during a couple of those times that i did not have regular two stroke oil.. but i read online that old dirtbike racers used to use it.. unsure of the ratio mix though...
