hello i recently bought a 69 bonneville. Before this i had daytona 500 with a choke cable and was simple too start. Now the bonneville has no choke and everytime i start it up it stalls out unless i put a little throttle on it....how do i adjust this without stalling out. ive read you dont need a choke cable. is it fairly easy adjustments..thank you
Either keep more throttle on until it warms up or fit the choke and use it. If you adjust it so it runs well cold with no choke then it will run rich when warmed up, waste fuel and wear the bores out .
Many people seem to have no problems starting these bikes and running them with no choke. I have had quite a few over the years and maybe I am unlucky but in every case they started better using the choke. There was then a lot of variation in terms of how quickly the choke could be eased off. Suggest you fit chokes to your Bonnie and see if it makes a difference. I think it will.They were fitted as standard in IMHO for a good reason. I see you are in NYS (I am in NJ) and with the weather now turning much cooler I can well imagine problems starting to move off idle with no chokes. HTH
ok thank you, i have plans on installing a choke cable, also the slides were removed so need those too...i live up near canadian border so its colder up here...i just see some say no need for it...i had one on my 1972 daytona..i just bought the bonnie 3 weeks ago and noticed it didnt have a choke..so plans are too install....thank u
It's exceedingly common to find the choke/s missing. Many owners chose to remove them to reduce complication. Finding the right balance of choke to use is the issue I'm recalling. The amount was either too much or too little so didn't suit all throttle positions. Refit choke parts by all means. At least it will be making it more original.
I removed my choke to keep things a lil' neater and found that even in the heat of Summer, I have to stand next to the bike for about 2 mins. before I can let off the throttle. If I let off earlier, it will die. Once it's running warm, the bike runs just fine. My throttle also has a screw I can tighten if I'd want to.
If you are around the N. border, I would highly suggest fitting a choke - especially if you will be riding in the "cool/cold" seasons.
One possible reason is float heights - some have posted they've removed chokes as not required, then dropped the float heights after finding they're higher than the recommended, "0.08in. (2mm) below the front edge of the bowl", then found they need chokes again ...
I don't have chokes fitted to my Trident, it starts easy enough but it does require a little finesse with the throttle and a finger on the left carb tickler to keep it going at first. I thought about putting the chokes back but I really hate the rats nest of cables required on a triple.
When given the choice between two evils I picked the one I haven't tried before
To add more muddy to the waters, I ride all of my bikes and I never use the choke. I start them using the tickler and I have fitted each with oversize idle speed adjuster screws. When I first start the bike, I just turn the idle up a turn or so and it warms up just fine. On my Bonnies, I find that you can increase the idle speed on one carb and it works just fine. If you want to reinstall your chokes, there are actually a lot of parts in the system. You need the lever at the handlebar, the cable to the splitter box, the cable splitter box, the short cables that go to the carbs, the slides, the springs, and the brass tubes that go with the springs. Idle speed screws are cheap and easy if you just want to fix the cold running problem.
Mostly Triumphs with a few BSA's a Norton, and two BMW's
