just because you have displacement and good numbers do not mean you will win. the ride style as was brought out makes a diff just as double clutching or floating gears.

you can take two engines with identical numbers and yet one will smoke the other. many people do not think about AFTER PEAK POWER. if i can pull 500 more rpm than the other, and i can gain 10 mph through the gear then i will leave the dude behind.

do not forget weight ratio.

 

Sounds like there is something more than just leaving 3 or 4 hp and tq on the table because of the exhaust...and that's on the bottom end. If the guy was willing to steal your radio I'll wager the mortgage money he short changed you on some motor work. It's also possible that the tune is bad...only one way to find out. Good luck

 

 

You also didn't say what bikes you were outrun by. The streetglide is a heavy bike, if you ran against 2 dyna's or FXST's then we may have found the problem! And just because it's an 88 doesn't mean it isn't hiding something inside that can whip your ***. Apples to apples and such....

 

I'm curious... what did the gentleman say when you caught him stealing your radio?

If it were my bike it would be something like "please don't hit me again!". Seriously.

On another note, lots of good insight on this thread, some not so much so. Some thoughts: Compression is a bit low, tune might not be the best, the duals definitely don't help, though with those cams, I would still expect the peak hp to be better. Heads also a possible issue. My first concern though, since the indy has already demonstrated a degree of dishonesty, I would check the build out and make sure it's what it was advertised to be.

This has all been said before, I'm just reinforcing it....

 

Hey came up with a lame excuse that my radio wouldn't make any difference, I was naive several years ago!

He also did some wiring work and taped the joints together, had to take things apart, then have them soldiered, this guy is a piece of work.

 

On another note, I have a friend that has an RC components full system he will sell me for $400, it's a 2into1 system, does anyone know the bung size for O2 sensors on a Thundermax?

 

Wow what a scumbag... Yeah you have to get it all checked out then sue his *** or sort him out...

 

just re-read the thread and had an after thought with my sport.

on mine, the carb is more or less a restrictor plate. if i would increase mine, it would pull up rpm much quicker than it does, i just need more open road to pull max rpm. i sorta left it that way as a protection to myself. when i drop out third, the speedo is history. i am not saying the carb is the problem because TOOOOO much carb is even worst. the same could be carried over to efi.
