Pretty impressive.  How do you like the exhaust? I'd like to do a 4-1 I had a d and d on my last Fj and it was insanely loud. Looking for good sound not a a lot of noise. Thanks   Beautiful bike by the way. Mine shows her age real well

Thank you.When I purchased the bike it had a Vince@Hines muffler.The previous owner gave me some extra parts,including the Remus muffler. For me sounds awesome. May be a little louder than the original that came with the bike. The other mod was a 89 forks and calipers and stainless steel brake lines. The problem was the 282 wheel rotor was small. I have the 16 inch wheel.A Yamaha v-max front rotor 298 mm was a perfect much. Due to a leg injury.I'm going to do some maintenance and replacing the alternator connector and the main switch connector{both are melted and have corrosion.Take the carburetors and sent them to RPM.May be I mod the stock air box and advance the ignition.I will very happy if I can get a few hp .Thanks to this forum I was able to do some maintenance on my own.If not RPM is the place.You can't go wrong with the knowledge this people have.
