At Dumont this weekend my header bolts snapped in the head and they need to be lasered out. What would be more economical, fixing and replacing piston with 11:1 JE, Stage 2 hotcam, valve springs, and rod, or look into increasing displacement such as 686, or690? Also, how much should a dealer charge for install of the parts along with lasering the header bolts? Someone please educate me on the 686,690, or ???727.

 

How did they snap? Over tightened to begin with, heat expanding etc? Were you working on it?. Just want to know for my information so I don't do the same thing. TIA

 

I think his nick-name may give the answer away.

 

Well, it happened in 2 stages. I did in fact install the header and 2 months later I wrecked at Dumont and one bolt snapped. I went to get it fixed (tapped) and the dealership broke off the tap, but because I was in a hurry to ride they tightened the one bolt down and high temp siliconed the header to the head and told me everything would be JUST fine until I had the time and $ for the internal engine accessories I wanted because they are going to have to laser the head for free. Afterall, they broke the tap off in the head. Well today running up Comp I droped the clutch the bike felt wierd, lost power, sounded different, I looked down and the header was loose. Going to Glamis in #wks and need to work fast.

 

Thanks, hope you get it all fixed up in time for Glamis.
