Small bore, big bore, small flange, big flange, minor dents????????????????? This shows he doesn't give a fuck what he sells and even more, he doesn't even know what he's selling. He's what you wipe off your ass.
With all the gearing changes I do, I always have at least 2 in my chain. I cut different lengths of small pieces of chain so I always use only 2. Best and most expensive way to go is one.
Hell yes. Stop by the auto parts store and spend $5 on some br or just plain old b9es plugs. Gap them at 18 thousends and try that. This may not be your problem but at least you'll be running the right plugs.
If I missed this sorry, but did you change your plugs to b9's and gap them to 18 to 19 thousands?
I went through this and after detonation issues and redoing the topend we figure out it was lean.
Are you blowing fuel out the pipes when you Rev it? If not I would say lean.
When the worthless piece of shit post a picture on eBay and then sends you a completely different part, you have no fault in the matter. Look on eBay and find you a good looking part and buy it. See what you receive. Then pull your for fuck sakes. That company is horrible and intentionally screws people.
They are a complete piece of shit company. They fucked me on a clutch basket at least 5 years ago.
Don't watch out, just don't buy from them and spread the word.
