Hey mate nice video. I have just installed the exact same system on my 2018 wr450f. I noticed there is a gap between the header flange and the head and it doesn’t close up when tightening. I think it’s meant to be like that? Is yours the same?
Hey mate I have a 18 WR and got that same exhaust as a slip on and noticed the clamp for the header is to big for the fmf header did you put some sort of clamp on or do you have no clamp at all?
do you have to check the valves a lot like you have to do on the motocross bikes? Im thinking about getting a WR 450 but I cant afford all that maintenance crap like the oil changes every 4 to 5 hours etc.
Connor 734 not really rust those stock pipes are not coated with anything so sometimes what u think is rust is just actually dirt and a little rust mix
