Strange sound after wheelie in 1. gear. Need help

[Mikkel67]

Hi,

Yesterday i god the gasket. I mounted it, and also used exhaust tape and exhaust paste on all the connecting parts (extentions) on the zards. I also used some paste and tape on the outside of the extentions on the zards to make sure that there is no leak anymore. And i don`t think it is leaking now. It can`t be..

BUT, i still have the backfire. It only comes when i let go off the throttle. And most/loudest when i let go off the throttle after heavy acceleration. Is the next step now to download a different PC3 map? Thanks fore all feedback.
