Does anyone know if the marble mod is as an effective way to fix the old backfiring issue as the pair valve mod?? It seems a lot easier to plug up the line with a marble:cookoo:
I did the marble mod this summer and it made a huge difference. There is still some very slight backfiring when coming off of a very hard throttle run, but much better.
I bit the dust and did the whole pair removal with Brocks Block off plates. I have to say that it seemed kinda funny for the first few times of riding that it didn't backfire! Seemed like something wuz wrong!!
