Ok, that’s all I need to know. I will just throw them back into a dark corner. I do have another question though. The heads I have on my 400 are weird. I can’t remember the #'s, but I think it something like 992, or 997 or something similar to that. Someone said they were 76cc smog heads that weren’t that good. But them someone else noticed they had double triangles on them and said they weren’t that bad. I guess I will stick with them for a while.
