The trauma of living with a stock motorcycle was getting to me, so I finally decided to do something about it.
The first thing to do was some routine maintenance. Out came the toolbox and in went the fresh oil (GTX 20W50 for now, next in line is Rotella 5W40 diesel synth) & oil filter. God, that made a difference to the shift action!
I also replaced the chain and sprockets with aftermarket ones (a lot cheaper and better than OEM). The 47 tooth rear was replaced with a 45 tooth one from the 1200 model to bring me out of the 4-5000 rpm "buzzy" range when cruising. Let me tell you guys who want to change an endless chain (ie no master link) & sprockets by yourself. It is a real bitch and you will be in depression for several days specially if you do it alone without any help, and you break the $25 tool that is meant to break the chain LOL.
I also removed the rubber snorkel from the airbox because it is said to give some gains in the top end. And the intake sound is much louder when accelerating hard.
Then I solved the mid-range lean problem (emissions) by raising the needle using 0.5 mm shims from radioshack. God-damn EPA prevents adjustable needles and any kind of external adjustment on the carbs including airscrews!! Ridiculous, what is mankind coming to? Anyway that made the bike much smoother and driveable too. Possibly I picked up a couple of midrange hp there.
But the piece de resistance is the exhaust. Since I call myself The Pipefather (apparently funny to some people who dont get it), ideally I would have done my own exhaust. But the labor costs are too much in this country to do anything custom. I was planning a full custom bent 4-2-1 header (copied from the best of course) & exhaust can of my own design (NOT straight thro filled with fiberglass, anyone can make that). I was even going to have it dynoed in the place nearby till I was given an estimate of the costs involved.
And then I found this for $100 and picked it up:
Its made by a guy called Dale Walker and he specializes in sport tourers like the Bandit and FZ1.
The package arrived today and almost immediately I installed it on the bike:
Well what can I say guys. The workmanship on the exhaust is absolutely flawless. That exhaust is from 1997 by the way. And even after all these years not a single spec of rust. Very well kept and an excellent value I must say. If I one day started making aftermarket exhausts, this is the product I would benchmark. No gimmicks, no carbon fiber, titanium crap, just plain well-engineered. An ideal aftermarket exhaust.
To give you an idea of how badly made the stock exhaust is performance-wise look at these pics of the midpipe:
its a lot bigger in diameter than it needs to be cause it contains the cat con, and look at all those dents in there so that it clears various chassis parts. Bad for flow, and bad for velocity. Phew!! Talk about badly made.
I havent ridden the bike yet after the exhaust install (just started to check for leaks and it sounds like a bike should already) so I will keep you guys posted on the bum dyno results (not that many are interested).The next step of course is to completely re-jet the carbs by overriding the stupid EPA system.
