Hi, i have a 99 Ironman with 50k miles on it, about a week ago it starting making a strange clunk noise when downshifting 2 to 1, when i am braking it's ok untill 7-10 mph, when it downshifts and rmps drop i hear a CLUNK and i can feel it, sometimes it's pretty heavy clunk soemtimes not at all, if i brake with different patterns the clunk chnages and sometimes even goes away. Please help with info?. Also i recently Put a PV and K&N on it, could this have caused it somehow? Also i have a Powertrain warranty till 100k , would the aftermarket parts void it ? So If you know how to fix this problem or any tips or any kind of info. All info Appreciated!


Thanks a Lot
