jimbob Posted January 25, 2009 Report Posted January 25, 2009 shee was doing it when i first got her but put it down to old plugs, changed plugs and it did it again so ever the optimist i put it down to bad plugs, then i stripped and rebuilt the top end with new pistons and afresh rebore (65mm) went out on her yesterday for an hour shee runs perfect and goes like a stabbed rat with a new set in but not for long it fouled 3 sets of brand new plugs in less than an hour, im using BP6ES and ive also tried B8EGV it fouled them too, im premixing at 32;1 with a decent quality oil (texaco) am i running plugs that are too "cold"? or is it a jetting issue. my mods are listed in my sig Quote
jimbob Posted January 25, 2009 Author Report Posted January 25, 2009 i really havent gopt a cluie when it comes to plugs. have i been running cold plugs? Quote
werner Posted January 25, 2009 Report Posted January 25, 2009 (edited) had the same prob. all of the sudden started going through plugs. believe it or not it ended up being plug wires. havent fouled a pair since and cheap fix. I run b8es Edited January 25, 2009 by werner Quote
2001Stroker Posted January 25, 2009 Report Posted January 25, 2009 Texaco is not a quality oil. That's probably most of your problem. Get a good racing 2-stroke oil. I would bump it to 36:1 to see if that helps. Use NGK B8ES, or BR8ES. Quote
jimbob Posted January 25, 2009 Author Report Posted January 25, 2009 (edited) excellent guys, thanks for you help and speedy replies, ile go and give it a shot 2mora with the right plugs and some castrol or rock oil Edited January 25, 2009 by jimbob Quote
mark101180 Posted January 25, 2009 Report Posted January 25, 2009 castrol is not a good 2 stroke oil. get ams,klotz,yamalube or basically anything you get at a motorcycle shop. nothing from a gas station or wal mart or autozone is worth shit. Quote

gregrob Posted January 25, 2009 Report Posted January 25, 2009 I would order some of this http://www.maximausa.com/products/2stroke/castor927.asp Quote
Rodneya Posted January 26, 2009 Report Posted January 26, 2009 I would not worry about the oil at all. What do you think all the 2 stroke street bikes use. They fill up with whatever is available at the gas station. At least that is what me and all my buddies used to do when I still had an RZ. Your carb's are quiet big for a motor with just porting, but that's just my opinion. :biggrin: Quote
AKheathen Posted January 26, 2009 Report Posted January 26, 2009 6 is qiute hot. if you are lucky, they will glaze before they detonate. doing a plug chop run with those, is asking for a rebuild. Quote
jimbob Posted January 26, 2009 Author Report Posted January 26, 2009 Your carb's are quiet big for a motor with just porting, but that's just my opinion. :biggrin: yeah a few ppl have said this but when it runs clean it goes like a stabbed rat easily wheelies thru the powerband in 3rd, could it be a jetting issue? ile try leaning the mix out and a cooler plug and get back to you guys Quote
jimbob Posted January 26, 2009 Author Report Posted January 26, 2009 oh yeah there is one thing i forgot to add, the K&N is pretty f*cked now aswell so thats probably not helping the situation much, so new oil new filter new plugs and a slightly leaner mix should see us ok. thanks again all, your golden nuggets of wisdom are beyond value and much appreciated :biggrin: Quote
jimbob Posted January 26, 2009 Author Report Posted January 26, 2009 ok get this. went down the garage today. same plugs same fuel, took the airfilter off and it ran like a f*cking MISSILE, airfilter is/was a K&N but its that old its not the normal reddy puirple colour its BLACK, Quote
