I just got home from riding for 2 days, and my banshee is acting retarted. I was going up a long hill and shifted into 4th, and all of the sudden the right cylinder went out. No more power. I took out the plug and inspected it, it looked ok, but I decided it'd be best to get another. I got a B8Ev (very good), gapped it to 30, and it still wouldnt work. I checked the gas lines going to the right carb, and they are all connected. What else could have went wrong? And of course, 2 raps, 2 ex's and a Z and Kfx rolled in, and I had a 175cc loser pos banshee. So that burnt my toast a little....

BTW, both sides have spark..

i would say you burned a hole though the top of the piston. it happens alot. do a cranking compression test on it. or just put your finger over the hole to see if it is as strong as the other side.

 

Yep, what dsmike said sounds about right. Check the compression, sounds like top end time.

that stinks.. well.. I guess I will do an update when I test the compression..

oh, and when I had the right spark plug out, the motor would still run. In this top end job, do I need to replace only the piston on the right hand side, or both? Do I need to get it bored? or just new piston and rings?

yeah well, those stupid queef's only raced me like 5 times. and most of the time, i couldnt get any grip. so i lost. except the one time i blew the one dudes 400EX, the yellow Z, and his buddy's EX. but when i did get grip i was pretty much even most of the time, unless i missed a shift or something retarted like that.

 

if there aint a hole in the piston, what about the reeds? Im still learning about two strokes though, not much experience with em yet. Just a shot in the dark.

 

sorry jakal, i doubt its the reeds, seeing it did lose a whole lot of compression. when he started it to put it in the garage, the left cylinder had a lot more of air pressure shooting out of the pipe than the right did. two strokes arent that hard. i think they're easier than 4's, but definatly not easier to keep running. seeing i had to have kopek on his kodiak tow me up the hill, so i could get moving and put iti n gear to start it. but it think it was the plugs fault. it usually isnt that hard to get running.

 

so 2 strokes are really hard to take care of?

 

You should be gapping your plug at 21 thousanths.
