NGK BPM7A
Short plug
Extended tip for better burn than other short plugs.
Ambient temps above 80° F
Heat shrink tubing works better than sandpaper
Not quite sure why you filed the chrome sprocket? as they are burr free and thin
You are gonna regret not getting my new 3 way mount 35 tooth cnc sprocket....
hey
Let me know how your build comes out......and if you have any problems give me a call anytime
Would be great if you could bring it to the meet at El Dorado park on Sunday June 14th
