I was dragging my brothers car one day. And after we got done dragging we were riding back to my house when all the sudden I had a huge backfire the quad died. At first I thought I flooded the spark plugs because I had a freind "Who never rides" playing around on it. So I go to change the spark plugs and the left side is perfect little brown not dry a little wet the way I like it a little safer so im told.
The right side spark plugg is missing the head of the spark plug and tehre is what appears to be little metal shavings around the spark plug.
I then put 2 new spark plugs in the shee and it starts up The left side is normal the right side kicks on and kicks off sounds like it wants to go but back fires alot so i shut it off because I did not want to cause further damage to my ATV.
It has not been ridden to much since ive done all my upgrading but I am confused as to why it would do this with very little ride time on it should I have been running a Higher Quaily of gas?
I used Prem. Gas mix with the oil 92 octain but was told maybe I should use race gas instead to help with compression. But when i did a compression check with a freind before I even ripped on her about a month earlyer the compression was fine.
Upgrades I have done to bike.
19-Domes
Cool head
4mm Stroker
Dynotech Ignition
Extended swing arm.
New tough chain.
Carbon Fiber Reeds.
2 into 1 Carb system
CPI Inframe Drag pipes.
lockout Clutch-- I Know its not really needed yet with upgrades but i got a good deal so why not. 100 bucks
I have yet to pull the cool head off to look in side to cylinder to see if it did blow because I live about 2 hours from were my ATV is stored and if im going to buy parts to fix it i would rather get them here at a local store.
I did all the installlation of the parts my self. I was told if i dont know anything about 2 strokes to not touch them so i took it apon my self to get to know my Shee inside and out. IM not the brightest when it comes to working with them but i can slowy find my way around.
Soultion if it is blown so im told is to Get it Bored out and all that good stuff and order a new TOP END KIT for it.
So questions to you guys.
YOu think i blew it or is that head of spark plug some were in my cylinder?
What TOp end kit should i buy for it if i have to? I have about 300 bucks to spend.
Should i be running higher octane in her?
ALSO CRANK IS WELLDED
thanks for future helpfull replys.
