Iron Cross Posted June 19, 2010 Report Share Posted June 19, 2010 ok here is the deal i went out riding in the desert of arizona last sat and sunday. i ended up fouling both my plugs out so the bike would bog down really bad. i took the bike home and pulled it apart and found out in needed outterwear very bad the carbs were all craped up with dust so i pulled them and cleaned them and put them back in. then i changed out the plugs with brand new ones obviously. since then i have tryed to kick her over but nothing i have been trying for about 3 to 4 days but nothing. so i pulled the plugs to see if there was any fuel in the piston camber and it was dry like something is cloged i dont know what to do please help me.. thanks Jason Quote Link to comment Share on other sites More sharing options...
Phelps Posted June 20, 2010 Report Share Posted June 20, 2010 have you done a compression check since it sucked up sand? checked for fire? make sure fuel is coming out of the tank? Quote Link to comment Share on other sites More sharing options...
68chevyc10355 Posted June 20, 2010 Report Share Posted June 20, 2010 To eliminate a fuel problem take out both plugs and pour some premixed fuel down the plug holes. If it fires you have a fuel problem. If not do a compression check and hope you didnt ruin the top end. Quote Link to comment Share on other sites More sharing options...
Iron Cross Posted June 20, 2010 Author Report Share Posted June 20, 2010 (edited) IT DOES HAVE SPARK I DID CHECK THAT YES THERE IS FUEL COMING FROMT HE TANK cuz when i pull the carbs they empty out everytime. i will try the fuel in the top and the compression test not to sound like an idiot but how you do a comp test.

68chevyc10355 Posted June 20, 2010 Report Share Posted June 20, 2010 Just becaust there is fuel coming from the tank doesnt mean that it is getting to the engine. First put mixed fuel down the plug holes and kick it over that will be the easiest. To do a compression test you will need a compression tester, which i assume you do not have, you will pull a spark plug out and screw in the line from the tester. Hold the throttle pinned and kick it over a fast as you can until the needle stops climbing (turn the kill switch off so that you are sure it wont start with the tester in). Tell us the results so we can help you from there. Quote Link to comment Share on other sites More sharing options...
Iron Cross Posted June 21, 2010 Author Report Share Posted June 21, 2010 (edited) ok i got it to fire upo and idle by putting fuel in it but it does not seem to run like it should i had it on for about 5 mins and it overheated and blew the overflow cap off along with all the fluid. so yea i took a 400 degree bath face everything. not sure how one day of riding and a little bit of dust. can make an engine be fucking retarted. it ran mint before the plugs were fouled out and the little bit of dust got into it. it idles fine but has a bit of back fire when you give it some gas would that mean i need to drop my needles in my carb down one notch???? as far as the over heating issue would dust have got into the coolent and cloged something. i wish i knew more about 2 strokes. i dont have a tester nor do i have any money to buy one kinda tapped right now out of work..

68chevyc10355 Posted June 21, 2010 Report Share Posted June 21, 2010 If it ran fine before the dust and now it runs if you put some gas down the plug holes and it runs the only things i can think of are your jets in your carbs are plugged, a reed is messed up or the crossover tube that goes between the two carbs is missing. The reason it could be running a touch off of what it was before is because the carb is not regulating the fuel to air ratio, thus not running at optimum. A while back i tore my engine apart and forgot to put the crossover tube between the carbs. It is a 3" fuel line that connects between carbs and is inline with the choke. Without this tube fuel will not get into the engine and it will not run correctly. I am not sure why it overheated so badly except maybe it was running lean enough that it overheated. So, check for the crossover tube and clean the carbs. Do you know of anyone who owns a compression tester that you could get access to? you could check with some mechanics and see if you could borrow it for the ten minutes it would take to check your compression. Even if your motor runs fine you may want to check it to see what kind of shape your top end is in. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted June 21, 2010 Report Share Posted June 21, 2010 Definatly clean carbs. Do one at a time to avoid mixing parts , they're different. I would pull intake boots and reeds to make sure they're clean. Inspect boots for cracking/rips. If you find any dirt / dust past reeds your effed, complete teardown coming. Don't run it till you completely inspect both intakes all the way to the pistons. Quote Link to comment Share on other sites More sharing options...
Iron Cross Posted June 21, 2010 Author Report Share Posted June 21, 2010 (edited) ok ty i will pull it apart and i will see what i have when i find out more i will reply to this post please keep checking back you all are saving my life with this deal. i am about to go out and tear it down now so check back and i should have some news up very soon. as far as a compression tester i will have to look into it i might know someone who has one but not deffinate...

Larry's Shee Posted June 21, 2010 Report Share Posted June 21, 2010 Auto zone or other auto parts might have tester on tool loaner program. BTW , pull both plugs ,it'll make it a little easier for test , pluss you have to do both cyls anyhow. Gas off , key off, throttle wfo , kick like mo-fo , lol . BTW, good morning , glad to see your at it early. Quote Link to comment Share on other sites More sharing options...
68chevyc10355 Posted June 22, 2010 Report Share Posted June 22, 2010 Any updates? Quote Link to comment Share on other sites More sharing options...
AKheathen Posted June 22, 2010 Report Share Posted June 22, 2010 if i had that much dust get in there, i'd be tearing everything down from the filter, to the reeds. you can see how much scorring is on your pistons with the reeds out. get the jets and little orifaces good, and wipe down all surfaces, including removing the reed pedals Quote Link to comment Share on other sites More sharing options...
Iron Cross Posted June 23, 2010 Author Report Share Posted June 23, 2010 ok here is the updates as of right now. i pulled the air filter off and there was a shit load of dust in the filter and the 2 into 1 peice that connects to the carbs then in the backs of the carbs there was a good amount of dirt. so i pulled off the carbs and cleaned in and out still have to get into where the jets are and clean them out good. now for the reeds i pulled them out and you can see a little bit of dust mixed into the fuel on them but nothing major.... i lookied inside of the block where the pistons are and i can see dark gas but it looks to be just the left over mixed fuel..... i stuck my finger in the holes to see anything felt like it had a grit feeling to it and nothing everything was smooth. but still tempted to take the top of motor off where the plugs go in to inspect further.. just need some opinions on weather i should or not... i took the reeds apart and cleaned them and the jets are next. as for a compression test i have not done one yet i wanted to get motor cleaned out so i do not do any additional damage. so i am open to all opinions please let me know thanks Quote Link to comment Share on other sites More sharing options...
Iron Cross Posted June 23, 2010 Author Report Share Posted June 23, 2010 here is a picture of the inner wall of the piston you can see the dark gas nest to the arrow this pic was a real bitch to take but i hope it helps out i will take more if needed Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted June 23, 2010 Report Share Posted June 23, 2010 I can't tell much from pic. How does piston look thru intake? Maj.r scratch? Maybe pull exhaust and inspect ex side of piston , crank engine over and inspect upper cyl.Easier and cheaper than pulling head. Quote Link to comment Share on other sites More sharing options...
