I have a triumph Bonneville t 100 2005 with 10,000 miles on her. I did a lot of repairs lately, changed the pickup coil, cleaned carbs and just about every other alteration that has been mentioned on this site for when the bike suddenly dies on the road in mid riding.
Without going into great detail (on the bike just turning off and dying part) the newest problem is while riding the throttle stops responding with the bike on. If I am cruising along at 70 MPH with a fixed position on the throttle, it is as if all of a sudden the bike just acts as if you stopped giving it gas and starts to slow down or sometimes jerks... if I rev the engine I get no response, the throttle seems to be dead or disconnected. Then as I’m coasting to pull over, just as mysteriously as this began, it comes “back to life” and starts to respond again. This happens several times mid ride and is very dangerous.
Please note when this occurs the bike is still running and has full power. It is just as if the throttle or the cable is disconnected or something.
I did take the throttle cables off when I cleaned the carbs but I thought I put everything back exactly as was and I checked all of the throttle cables and nothing looks out of the ordinary.
Any have any suggestions or have this happen before?
I'd suggest you first make sure you know how it came out. In other words, make sure nothing is bent or broken before you just fit it back together. You don't want this happening again.
The problem is that the throttle cable is set to the loosest setting already at the handle bar throttle grip and twisting the throttle doesn’t help because that brings the cylinder further away from the housing, not closer. There is currently not enough slack in the throttle cable line to maneuver the cylinder into the housing. Grrr
Any suggestions?
Silly question, but was it working fine before the work you did to the bike? If so then it's most likely something you are missing. Did anything get swapped to a wrong position?
The throttle was working fine just other aspects of the bike were not..
I have no idea how it should look.. if anyone has a picture it would be appreciated.
What is the cylinder piece used for and why is it even necessary? What would happen if I would just snip off the cylinder so that it could not get snagged any longer?
DO NOT CUT IT OFF ...it goes through the slot and back /up to the cable housing yes there should be play [ very little ] untill you twist the throttle on ,then the cable comes down out og the housing and [INSIDE] that lip to keep it rotateing straight out ...its a back up to release your throttle on full throttle ..one cable on one cable off .... yes you have springs to release it but with all the rust it could stick on you need to spray the **** out of all the carb linkage ,and any where it moves with p.b. blaster [ or ] it looks like it was under salt water ..the carbs should work [ go to off with out that return cable ... but its nice to have it if the slide inside sticks you can close the throttle ...i am in daytona ..e mail me direct at rodriguezroy65@gmail.com and i can take photos of mine 2002 to give you a better idea ...
chance when you took off the carbs it slid out of the slot .. by having some one twist the throttle full on you can with a needle nose pliers pull enough slack out and twist it throuch the slot [ maybe ] .. or you will need to disconect at the throttle plastic twist end to give you the slack ...or remove the carbs and put it back ....if you rejet just remove carbs from the left side ..flip over ... over a pan to catch the fuel from the vent tube ...[ leave both cables on ] to remove the bowels ...when done flip back over and install carbs ... easy
Thanks for the awesome pic Rich, I just don’t want to pull everything apart... I am hoping to be able to get it back in the housing as easily as possible but this diagram will serve useful nonetheless. Thank you RJ
Both cables work together in a 'Push-Pull' arrangement to ensure smooth throttle operation, and ensure the throttle does not get stuck open. It would probably work without the return cable attached, but will rely on the throttle return springs to close the throttle. I would suggest you re-connect the cable as it is a valuable safety feature above all else.
I had my throttle freeze open on a 100cc Yamaha once, on ice. Not pleasant. I would have given anything at that moment in time for that second cable to force the throttle shut, which the bike did not have.
if you ride it /truck it to daytona fl. FOR SOME reason we can pull it apart in my garage . e-mail me rodriguezroy65@gmail.com ...ya i know long shot but if your in area i would be glad to help .. have the tools ,time, beer ..and have had mine off a few times 2002 bonnie ...
Thanks Roy for the kind offer. It is a bit far but if I am going to be up in that area I will definitely contact you. thanks again.
In the mean time I am trying to “borrow” a friends garage. Lol but many don’t have one in the city... I wonder if other people have had any success in getting the little bugger back in the encasing without pulling off the carbs? Maybe a suggestion I have not tried yet or maybe I over looked..
R.J. 10-4 long haul ..only other thing i can say try would be to un hook cables from inside of the twist grip to give slack [ maybe ] as they are pulled around the plastic and hooked like the carbs linkage... BUT you have to loosen the bars and move to the left to slide the throttle assy. off ,open the 2 screws to open the housing .. then you will see the one cable over the top and the other under the plastic ..[ need to remember which is which...and sort of twist up till the return cable comes out ..that will give you 2'' of slack on the inside cable which [might] give you enough play to hook the carb end ...i had to replace my plastic twist part as it cracked .. so it can be done ,x-tra set of hands helps but not needed ...BUT i do not know if there is enough slack at the carb end but 2'' might be good .. then rehook it to the top plastic twist-slide on
I will have some spare time this weekend and will give that a shot. I will let everyone know of the progress. If that doesn’t work I will have to find a nearby garage to just take off the carbs again. :/
Wow, do I feel dumb. I spoke with Jay at kreemsicleT100 and he suggested to take off and just unscrew the throttle screws where it connects by the carbs. And sure enough, the assembly and hence the carb cable dropped an inch or so and gave me more than enough slack to fit the little cylinder back into the housing! What a relief and a quick fix. It took all of 5 minutes. I drove her about 10 miles and no problems although I have thought that before so I will ride her all weekend with the girlfriend on the back as well to see if the cutting out or the throttle not responding randomly still give me any problems and I will report back. Crossing my fingers that all is well now and thank you everyone for responding, taking the time out of your busy lives and helping me. much appreciated!
Haha no reason to feel dumb. We've all been there when you just gotta see it from another perspective. Now you've learned something Kudos to you for even undertaking the project. Now I hope your CDI problem doesn't pop up! At least you know about the seat trick.
great now WE ALL know ..thats why this thread works ..some one must of done it at one time .. share the pain ...
