Your jetting is WAY OFF.....your getting DETONATION. You might need high octane fuel or even race fuel depending on the domes you have. Get a compression check done so we know what kind of fuel you need, then go 3 jet sizes bigger, then back your way down after your learn how to read plugs.

DON'T ride that until you fix it unless you want to be buying a new motor. Check your jetting and compression. Quote
Jereme6655 Posted February 14, 2011 Report Posted February 14, 2011 Yup....like windycityjohn said....your detonating. The constant hammering of the sparkplug and the cylinder dome is jarring the spark plug loose. You can keep riding it if you want.....but i guarentee you that you will wind up doing a full rebuild on a totally blown-up motor REAL soon if you do. Id either call the previous owner or do a compression check and then post up your findings on the HQ here and we'll help you get her figured out! Quote
fastquad02blaster Posted February 14, 2011 Report Posted February 14, 2011 Can you say," the whole bottom of the spark plug is smashed or melted?" Yeah, I agree with the others. You need some higher octane fuel or back off the timing a little and bigger jets. Fix it before it blows and it will be funner for you and a little bit cheaper. Quote
camatv Posted February 14, 2011 Report Posted February 14, 2011 deto fo shaa PD domes after they have been detod a few time usually wont hold plugs. you may have to get new domes also. Quote
