I just got a 02 bonneville. I used to have a 79 D model. Obviously I need to change the exhaust. I want people to hear me but I don't want to piss all my neighbors off. I am looking at the D+D pipes, Sprint, and Norman Hyde Togas. I am also on a budget. Any suggestions.

Secondly, when I priced out the exhaust at my local dealer, it came out to be $1000 for the bub pipes along with the jet kit and the ai removal (including labor). Is it difficult to jet the carbs yourself. Do you have to do everything at once? If not, does it matter which comes first? exhaust or carbs and ai removal.

Any advice will be great.

Before spending $$ on aftermarket pipes, read the theads in Twin Talk about removing the silencers and drilling out the baffles inside the factory mufflers. No cost at all (if you have a few basic tools), and if you don't like the results you can then go buy the aftermarket stuff. BIll

I second Bill's suggestion regarding pipes. It will cost you very little to modify your stock silencers and the results may be all that you are looking for.

I would definitely remove the AI ASAP. My dealer did this as part of the deal prior to me picking up the bike. The Bonnies run darn lean from the factory. Virtually anything that you do to improve breathing and/or lessen exhaust restrictions, will require rejetting or you will run even more on the lean side.

This site, Triumph Carbs, has pretty good instructions for rejetting the carbs on America's and Speedmasters. Bonnevilles are very similar. A suggestion, if you do the rejetting yourself, replace the stock carburetor screws with decent screws. The kits are available from NewBonneville and, I think, BellaCorse.com.

According to the dyno, I gained over 5.5 peak HP by rejetting to 120s after removing my rear baffles, drilling the remaining baffles, and removing the snorkel. The gas sniffer shows the mixture is OK. The torque curve has definitely improved.

Jetting the carbs was WAAAAY easier than I could have ever imagined. The hardest part is unscrewing those crappy brass screws with the tops stripping off.
Jets are inexpensive. Don't be suckered into a "jet kit." Buying the jets separatly cost less than $15 buck. Some manufacturer tried to sell me the exact same jets in a "kit" for $99!!!!!!

Thanks for the advice, guys. That is exactly what I was looking for.

The high grade Togas from Hermy's in PA will cost about $425 delivered to your door by UPS. You will need the allen head carb screws, new mains (125s) and an AI removal kit for a total delivered of about $50.

On a scale of ten where rebuilding an engine would be a ten and changing a light bulb would be a one, installing the new slip ons would be a two (I had to re-tap the bolt holes in the silencers - otherwise a one), installing the AI removal kit would be a two, and rejetting would be a two.

For another $300 you could remove the air box, install K&Ns and rejet to much larger sizes. This would be closer to a 4 considering the work to get the old airbox out and the need to shim the carb needles.

Any suggetions for carb adjustments after drilling the mufflers on my '96 thunderbird?
