Triumph Bonneville T120R Setting the float levels

[martymcflyca]

Thanx for this video Lunmad! Really helpful on this topic. I didn't really understand what people meant when they explained this process to me. I put it in one of my playlists so I can find it again when this particular step comes up!

...hello Lunmad, I tell ya that I did the opossite way in my 626. I did what say in some manuals, to heat the bowl and the hit the other way (from down side), so I have that brass thingy more "tall" right now

[rallycamaro]

Wouldn't it make more sense to measure the gap while pressing on the actual needle, not the float flange? It seems more important that the needle range is addressed instead of the float range. I have my float at the acceptable level when up, but I believe this is too low for the tickler to even contact the float and she will hardly run on that cylinder. Perhaps my floats have gotten misshapen?

Thanks,

Thanks Joe :-) it will make a big difference when the carbs are set up,

don't forget to sync the cables (slides)

let us know how you got on!

hey, great videos man! you've helped me so much with my '71 bonnie! question: i recently did a full cleaning of my carbs and set the floats. now left carb doesn't flood when i tickle it. is it possible i set the float too low?

when pressing on the tabs when should i stop pressing? when the pin goes into the hole, there is a little room left for me keep pushing down. should i stop right when the pin gets seated? if so, i can definitely see how i would have set the float level a little too low.

[lunmad]

Hi bja214 :-)

glad my vids are helping.

You should press lightly on the float when the tangs are at the bottom of slot thats enough.

I extended my tickle buttons using a small (cut down) nail, what fit in the roll-pin.

excellent video! thank you lunmad! i must admit didnt even know there was a float hieght specification on amals! shows how dumb i am! ha ha ha! greetings from argentina!

[lunmad]

Cheers mac163, :-)

You can also use an extra gasket on the float bowl,

if its running a bit rich.

THANK YOU! What a great informative video! The Bonnie sounds great too!

[lunmad]

Cheers billywiz, I'm glad you found it useful, :-) I have just done another couple more vids on the Amal, with a bit more detail.

The Bonnie is sounding better all the time :-D

the new Boyer MKIII ignition I have just fitted has made a big difference.

Re Lucas:

"Gentlemen do not motor after dark." Heh.

I've never used any electronic ignitions other the stock '79 one, but I do like to replace the rectifier/Zener diode with a solid state Tympanium rectifier/regulator. Mostly just for less wiring.

[lunmad]

Hi gordonemoore the Rita was on the bike when I bought it, I have kept my Zener Diode but replaced my rectifier with a solid state one. If/when they give up I will probably fit a Tympanium reg.

"Gentlemen do not motor after dark." especially when your lights are crap :-D

Reminds me of the "Dyno Did'nt Start" by Wipac! :-D

[gordonemoore]

I've found .090" to work well.

[lunmad]

Cheers gordonemoore I ended up with the floats set at about .080" which has improved it a lot. But as I found out later my Rita ignition was at fault :-( I have since fitted a Boyer, which has got rid of a lot of problems. I should have put my hand in my pocket a lot sooner than I did. :-D

Great video, very helpful.

[lunmad]

Thanks very much 515miker515. I'm glad you found it helpful :-)

[oldtoughastheycome]

This is a very useful video and I applaud your efforts to bring it to the many Triumph owners/tuners who will benefit from it. I will certainly be more confident in adjusting the floats on my '72 Bonnie as a result. Thank you very much, RR

[lunmad]

Cheers oldtoughastheycome ( Great name) the vid gives the jist of how to do levels I wish I had thought about it a bit more. next time :-)

[Eldelacuchuca]

great video

[lunmad]

thanks Eldelacuchuca :-)

[lunmad]

Glad you liked it

nosilanoxid I eventually set them to 80 thou and have cured most of my rich problem, I wanted the seats out on this occasion.

You can knock the seats up from the bottom with an 1/8" drill bit shank through the hole where the banjo goes.

I wish I had pointed this out! in the vid

[pj3atcencol]

This particular video should be a "sticky" on all motorcycle forums.

Many thanks.
