When I bought my 400 the previous owner had removed the spark arrester/baffles from the exhaust. I have recently had to take the carb apart to clean it due to me having not ridden/started/moved it in about 8 months and found it had what I assume to be stock jetting (38 and 140 I think, main was not a concern at the time so I wasn't checking too close). Anyway, I've just been told that this gutted exhaust could lead to top end damage, especially valves. This set up has maybe 15-20 hours of riding after the arrester was removed, usually medium pace on gravel roads or tight woods trails in 1/2. My question is simply how far gone am I right now?
I've noticed it's hard to start and keep idleing, but I've always attributed that to the factory jetting (I never wanted to tear into a $3000 investment to change jets unless I had to). Anyway, I will be replacing the exhaust with a stock pipe with baffles/arrester next week, but I'm afraid the damage is done now.
Thanks, James.
