Tomos Targa stalls...

Danny Bernier /

Well, i just got a 2000 tomos targa for 100 bucks from a friend. Alot of parts needed to be tightened, and the left front shock/fork is bent. It also doesnt run up to par and im trying to fix that. It idle a little high, to the point where you had to hold the brake to keep it form driving off. I adjust the throttle cable a hair, and now, it idles nicely when sitting, but will eventually stall, and its getting worse. It prety much stalls everytime i come to a stop. Whats the proper way to adjust this?

Oh, and i bough a new sparkplug, autolite, and plan on getting a 27tooth sprocket, and maybe an exhaust. I need to to do at least 40 around my area. Is there anything other than exhasut in the same price range that will get me there, besides internals. SOmething bolt on. O like the quiteness of teh exhasut. Any help is appreciated. Thanx, danny.

clean carb again. try adjusting your idle again. too low, and you will stall, too high, it will engage your clutches. not good either.

if it was me, i'd concentrate on fixing/replacing your forks before worrying about doing 40mph.

Re: Tomos Targa stalls...

Screw the idle screw in all the way...then back it out two full turns. That's where the idle sits well on my 2000 targa. Then make sure your fuel line is clean from the pet cock to the fuel filter in the carb. Once you get good fuel flow and a proper idle I bet it will be all it takes.

Re: Tomos Targa stalls...

A good idle depends on a few things... A clean carburetor, no fuel or air leaks in or around the carb, especially no air/vacuum leaks between the carb and the cylinder. Set the float level where it belongs..

And get the engine nice and hot before adjusting idle.

Adjust idle on a cold engine and it will idle just fine when the engine is cold and die otherwise.

Fast idle speed is not really an idle. The carb is actually drawing some fuel from the main circuit in the carb, not just from the idle circuit.

As far as getting that thing to 40mph without a performance exhaust (as well as a couple other things) you will need more cubic inches.. or cubic centimeters... or a long steep hill.

Re: Tomos Targa stalls...

it seems like you adjusted the throttle cable tightener above the carb instead of the idle screw on the carb itself

take the airbox off so you can look down thbe carb and see the slider, adjust the thorttle cable tightener to where the slider goes almost all the way down at zero throttle and all the way up at full throttle.

then go ahead and adjust the idle screw

ok i read all the posts in this thread and i have to agree with paul. replace that fork first.

clean the carb out thoroughly. make sure the bolts on the intake are tight. that year tomos is prone to vibration which causes the manifold bolts to loosen up. i recommend using blue loc-tite on them.

once the carb is clean, remount it and make sure everything is sealed and tight.

adjust the throttle cable so that when the choke is closed, going full throttle opens the choke.

after that start the bike up and warm it up. while on the center stand, adjust the idle screw so that the highest rpm can be attained without the rear wheel spinning. now, it may turn slowly, but if you can grab it by hand and easily stop it, thats good.

a bi-turbo exhaust with a #56 main jet in the carb will put you in the 40-42 mph range with the 27 tooth sprocket. i have the same bike with the same set up and easily run 42 mph.

Wow, thanx for all the good info guys, and yes, i have already ordered a new front strut. But is there anywhere i can find some good info on basic stuff liek changing tranny fluid and dessembling the targa? I am an experienced mechanic, but never dealt with motorcycle at all. Ill probably end up just tearing it apart anyways when i get some go fast goodies, and spray it gloss black while im at it. I want to add some small lights inside the brake light for night time driving, i noticed that there were none. I picked this up for 100 bucks and never realized how much fun there is to be had.

Only thinkg is i need to find out the requirments for driving it in florida. I dont know whether i need a motorcycle license or not for it. Gotta call teh DMV. Thanx again, danny.

If you want some good info on the Tomos mopeds inside and out check this site out: http://www.mopedriders.org/article_cat.php?fldAuto=2

Go to the Tomos sections. There should be 4 separate manuals on the Tomos moped with the A-35 engine. I have used these manuals to do all of the maintenance on my Targa.

I had the same problem with my tomos.

After trouble me and my buddies realized that the vent in my gas cap was clogged and that I was creating negative pressure which at high RPMs would stop fuel from entering the carb.

I changed the gas cap and presto, didn't stall yet.

yea but he's having idle problems. that wont apply here.

Screw the idle screw all the way and turn out 2 full turns. Sometimes it slowly unscrews itself because of the vibrations of the engine so you need to check once in a while.

or loc-tite it.

Re: Tomos Targa stalls...

that is not the correct way to set the idle screw. no idle screw in the world has a set number of turns. you adjust these to attain the highest idle possible without the back wheel turning or the clutch engaging. would you want your bike to idle fast enough that it drives itself? i sure dont. and i know how to adjust these bikes as it is what i do for a living. if your screw is vibrating out, your missing the spring that goes on it.

Re: Tomos Targa stalls...

I agree with donp. you can't generalize how to adjust things. especially idle screws, every tomos in the world probobaly has a different idle screw setting.
