Bonneville America Forums Forums General Motorcycle Forums Member's Rides My first Triumph

Still looking for a T120 or a T140 basket-case. The few that I have seen are missing parts or just ridiculous expensive. Other complete bikes are either bobbed or chopped and some of those really poorly. Then I spotted this bike. A 2003 T100. Price was right and only 3600 kilometers on it. Now I have over 6000 K's on the odometer and can't get enough ride time on it. Need to find a job where I get paid to ride my Triumph.

And while looking for your vintage bike, you have a nice reliable modern Triumph to ride (which as you found out, is no hardship). Nice bike!

Love the T-100's nice bike.

remove the AIS system and that should do away with your popping. And any blueing of the headers. Oop just looked you have blueing already, but popping would go away

Sometimes just unplugging the TPS at the carb solves the popping on decel.

Or adjust the idle up just a tad. Better yet,get the carbs jetted correctly and it goes away entirely.

@edmspeedmaster
Been reading up on the TPS. Apparently, it has no effect on carbed bikes. It seems that it might advance the timing at the Igniter. I will have to give that a try. TPS is only a potentiometer and maybe some fixed resistors might actually set the advance. Again, something that I might try.

@tigeramerica
Not ready to do any carb work on those CVKs. Overall, I am not impressed with the vacuum slides. Looking at going with another carb setup. Won't be FCR or Mikunis. Looking at other options though. Still too busy riding to be thinking about mods. That's coming though when we get another miserable, long and cold winter here. The airbox is gonna get the boot and the stock exhaust is going to stay till I see something I like. All I have done so far is yank the little Kazoo pipes out of the end of the exhausts. Much better sound and still legal - I hope.
The AI will get yanked as well. Really no need for that if the carbs are jetted properly. I don't mind the blueing on the pipes, it's the putrid brown colour that ticks me off.

BTW guys... appreciate your comments. Any suggestions that might point me in a different direction or point out errors are always welcome
Don't think that I am a know-it-all, I have been around bikes before but that was a while back. I do have a lot to learn about the Bonnie and it's 'new tech quirks'. Looking forward to getting more involved with the tech side of this forum too.

no point in different carbs without further work being done to engine so more air/gas can even be used. Yanking the ai is iffy whether or not it does anything. In my case it had no affect at all,working on the carbs jetting was easy and totally noticeable!Just think how much more helpful we would be if you actually had an America,or speedmaster!

LOL Ya, well, I have my Bonnie and very happy with it. The only reason I want to yank the AI is to stop the damn lean outs. The AI does have a purpose but I think it is inconsistant depending on altitude and temperature.
And agreed on the engine being able to breathe. The two biggest restrictors are the stock exhaust and the airbox. As far as I know, the 790 cam is fine for regular street performance. I am not trying to squeeze 80 horses out of this thing either. What I do want is better driveability and I feel the CVKs are just too hurky-jerky for my liking. Usually when I am feathering the throttle at low speeds, it feels like the slides just slammed shut or popped open, depending on which way I'm twisting the throttle. This doesn't happen all the time and I really find it annoying when it happens, especially when taking a slow corner.

The jerkiness doesn't sound anything like what it should feel like at all. My ba is a 790 and even before rejet I would have called its throttle response very manageable.

Hmmm. If the weather holds, tomorrow I will make a D-Tool out of a piece of copper tubing and try turning out the Idle Mix by a 1/4 turn. Hopefully that will help when I'm running a bit off-idle.
Might block the AI at the airbox too and see what that does. Bike idles fine at 1050. Tends to wander a bit at idle but pretty steady.

The bike is tuned to pop. I tried to stop it a few times years ago but it's the nature of the beast. It's not an issue, it's a feature. Lean pop! You can stop it by tuning rich, or by pulling your "choke" out. Personally, I just accept it as a part of my favorite machine ever. Sort of like a slightly annoying habit of the woman I love, it sort of grows on me and I'd miss it if it was gone.

HAHA. I like that. Tuned to pop. And you are probably right. I think that some bikes have it worse and this is where some riders try to remedy it. I only get popping after a hard acceleration with a sudden slow down. Might be best to leave things as they are and just experiment a bit. Don't want to get into anything real serious just yet. Would rather ride

Popping a little is fine but if your hearing distinct "bangs" then it aint tuned right.

Pull the AI, turn out "idle mix" out 1/4 turns till popping stops on decel, balance carbs.

My nephew has an 03 sapphire and white T-100, likely the most iconic of the New Bonnies.
