Just re-read your first post.
It appears you're having two issues.
1) Excess heat
2) Not making the right sounds
Problem 1 isn't something I could help you with, I'm not as much of a gearhead as others here.
However, I might be able to shed some light on problem 2. You might want to sit down for this.
Our bikes are a little different than the ones we used to hear. They take advantage of more modern tech, are computer controlled, idle at higher rpms, now have fuel injection, and... run more smoothly. To have a bike that makes the right, "potato-potato-potato" sound at idle as well as the top fuel dragster music at full throttle you might have to add more parts, ( talk to Bubbie about cams, that might help ) or, get an older bike. Some on this forum say the Evo, others say the Shovel Head was the last bike to sound right. I don't know. One day I'd like to find out.
What ever your solution is, I hope you'll share it with us!
Cheers!
You have a great point, I can remember my uncle pulling up on a old FLH and that thing sounded like it was a monster. I do realize the differance between the new and old, better yet the not so old carb models. The faster idle dosnt bother me as far as sound goes, I love that when we go some where that I can stand around a few more min while everyone elese is trying to warm up their bikes "LOL". Its that it sounds great accelerating, but when I drop the throttle or decellerate it dosnt sound like a harley, I know the fuelpak shuts down the injectors on decell. but you can adjust it, and when you do what they tell you to it runs bad, slugish and ratty like its got a intake leak. so I started this post to see what people thought and alot of people like the TFI. I have asked a few people and I think I might be getting on some nerves by over asking I guess. I understand that they run lean from the factory, and harley will tune them lean. So I need more fuel to richen it up a bit. What I dont understand is that is everyone that dosnt put some type of programer on their bike after they add pipes and a breather hurting thier bikes in the long run buy the computer not being able to make the nessasery adjustment to meet the needs of the extra air and exhaust? Or is it just for performance?
