J.J. Posted September 24, 2004 Report Share Posted September 24, 2004 Yamaha Banshee Rider, no disrespect intended, but it sounds like you may just be in over your head a bit. Get that Clymers manual and start reading, if you still think you can split the cases after that, we will be here to help you through it. BTW, any particular reason why you took the head off and how do you know there is sand in the crankcase? Quote Link to comment Share on other sites More sharing options...
Titanium Posted September 24, 2004 Report Share Posted September 24, 2004 Are you sure the marks are from debris? They could be pot marks from detonation. Quote Link to comment Share on other sites More sharing options...
Guest Yamaha Banshee Rider Posted September 25, 2004 Report Share Posted September 25, 2004 I am pretty positive that it is sand or something in my motor, i will tak e a picture of it and put it on here so you guys can see for yourself, but i can't tonight cause i am not at home, i will do it tomorrow if i can get my friend to take a picture and put it on for me, i will try to put a picture of it up tomorrow Quote Link to comment Share on other sites More sharing options...
brock_fuzzy_69 Posted September 25, 2004 Report Share Posted September 25, 2004 dings in the dome of the head are most likely from the motor having been blown up before bits and pieces of bearing piston or circlips are know to come up and dent the head when a motor goes boom maybe it blew up on you and maybe it was blown up and rebuilt veery very very very common to see the dings in a banshee head or any other 2 stroke for that matter Quote Link to comment Share on other sites More sharing options...
2Smoker Posted September 28, 2004 Report Share Posted September 28, 2004 hey, i took my head off and i looked at my doomes, and they have marks on them from debris in motor, and there is still debris in motor, how or what should i do to get it out? please help I don't think I've ever seeen a banshee head or any previosly blown up 2 stroke head for that matter without dings in the domes. If they're really bad just take some rough sandpaper or better yet a dremel tool to smoothern them a bit. No big deal. You can split the case and expose the crank to properly clean it, but most of the debris should go out through the exhaust ports anyways.

frocashmoney24 Posted September 28, 2004 Report Share Posted September 28, 2004 how do the pistons look? Quote Link to comment Share on other sites More sharing options...
chase73 Posted September 28, 2004 Report Share Posted September 28, 2004 (edited) LOL get a dremmel and take some materal ofthe domes thats good . Allrighty now first of all it is very unlikely that sand made the marks in the domes its more then likely what the others said a previos engine failure Or a engine failure has just happened to you . It could be a piece of the piston bounced up into hte head and blew out exhaust or a piece of a ring ???. how do the sleeves look ???? what was the compression before you took head off ?????? sounds like to me after you answer all the normal diagnostic ???,s your going to have to rebuild this engine now as for metal in the crank after you remove cylinders look inside and see if there is anything in there check to see if the main bearings have any play and if there is you have a couple options the right way and the hacker way I have done both first off the right way is to split the cases and clean her up and check the internals while you are there replace seals ect . the hacker way is to pour some mixed fuel down in there wash it around and clean her out turn it upside down blow it out with air hose and check and recheck to make sure its all out anyway do the diagnostic tests and then let us know what the true condition of the engine is ....... Good luck the first one is allways fun dont forget to download the clymers manual from the site that way you can just print out the pages you need because they are going to get messy Edited September 28, 2004 by chase73 Quote Link to comment Share on other sites More sharing options...
banshdog Posted September 28, 2004 Report Share Posted September 28, 2004 my stock head had dings in one side. found out that it was from pieces of the top ring. Quote Link to comment Share on other sites More sharing options...
Bansheeman1121 Posted September 28, 2004 Report Share Posted September 28, 2004 As stated above there is lazy way to clean the cases, i was just about to put my motor back together with m y new pistons and i looked down in the cases and saw about an inch of metal shavings from the piston that melted, not sure if its safe but i bought some carb choke cleaner and spryaed it all loose then pured some gas down swished it around and pored it out then i took a rag and cleaned anything i saw still in there. the dings in the domes are probably just from a past top end that grenaded or ran hot, my coolhead domes are a bit nicked up from the one piston getting to hot and melting so little pieces melted to thew dome and scratched it, my stock head i bought used was a mess so i smoothed it out with some sand paper bit i doubt its sand the motor would have already gone if you ask me Quote Link to comment Share on other sites More sharing options...
