You can certainly adjust the low (pilot) and mid-range (needle/white spacer) without rejetting. Not rejetting will simply cap your high end.
Back on 05/14/06 Brewbrother posed some questions about carb mods. Essentially, he was looking to reduce engine operating temps in order to protect his engine. Savage Rob gave the above response. There were others, all very informative, but that one really struck a cord. I'm not interseted in improving performance. I like the performance I'm getting. I do; however, want to protect and extend the life of the engine.
So how did all that turn out? What did Brewbrother eventually do; and should I do the same? I want this bike to last, and heat kills engines. I've got an '08 S40. I'm sittin just shy of 1,000 miles, and I love this bike just the way it is. It's got plenty of get up and go for me, it only occasionaly needs half choke to get it started first thing in the morning (and that only for about a minute or less), great acceleration, the fastest I've ever been on it was a BRIEF period of 85mph, with throttle to spare. It will, on RARE occasion, when the engine is cold and the humidity high, give a faint backfire when I roll off the throttle. It does a slight pufffft on shut down that can't be heard if you're not standing very close to the bike. It does have a VERY slight lag in the 45 - 50mph range, and I've noticed just a hint of faint gold on the pipe at the heatshield.
Now all that said, if I DO need to perform some mods to save the engine from premature death, which ones do I perform? Bear in mind, I'm not interested in breaking the ton, I don't need more top end speed, I don't want it to sound louder (I like the sound: and if I ever take the badging off the bike, I'm going to replace it with
Tecumseh or Briggs&Stratton
) so I won't be replacing the exhaust. I change oil frequently (it's had four oil and filter changes since purchase), and I plan on converting to synthetic after 2000 miles. I may even put in a magnetic oil plug, but I digress.
Full disclosure, I am not a tinkerer (sorry Lancer). I will wrench, but I prefer to ride. However, if it will save the life of my ride, I will get the toolbox out. So group, what mods do I have/need to make in order to preserve my beloved ride from the heat?
Seriously, if the heat is a problem I want to fix it. Most of the tech advice in here is for wringing more performance out of the Savage. I just want to protect it. Please advise.
Thanks,
