Hi everyone, Been browsing through some interesting topics on getting the S40 riding at interstate speeds. Mostly rejetting, and grinding out the exhaust port, was said to improve mpg and top speed.
Almost every topic I see, is about the top speed of the S40 being limited due to: 1- vibrations 2- lack of HP 3- too high rpm.
Vibrations seem to appear around 80mph, and merely an annoyance, not a limitation; But they do hold people from going any faster.
Essentially lowering rpm by 10%, would move up the vibrations by almost 10mph. Number 1 can be solved, by regearing the bike, lowering rpm. I wanted to know if there is a front pulley for sale with 1 tooth up from stock, that fits?
I'm not too fond of the pictures I saw of the chain conversion, unless a chain guard can be used. The stock one preferably, even if the rear sprocket is 3/4 the size of the pulley.
To make a re-gearing possible, the engine needs more hp (for top speed). I read about someone drilling out the exhaust ports with a dremel. It should increase hp, and mpg. Add a more free flow exhaust if necessary (or in some cases, replace the air filter with a more modern one), and compensate with a slightly bigger main jet, for a richer AF mixture. Should give at least one to 3 extra hp, which is 10%.
Any other suggestions, concerning pulley system, or a nice looking, affordable chain kit with chain guard?
Also, any ideas about making the engine vibrate less by balancing it out? I once saw a video of a guy who would just drill a .2" by .2" hole in the counterbalance of his motor; which reduced the weight of the counterbalance, and made the engine run smoother.
