07 Vento Triton, Air & Exhaust leak, maybe By mikey34 (Read 2,780 times)

It will Idle just fine and Starts first try immediately. As soon as I try to twist the throttle, it will die unless I let go, Pump the throttle, or if I cover the inlet to the airbox, WHILE taking off, it will go ahead and get going. AFTER I get going, say 10mph, it will go just fine WITHOUT me covering the inlet.

I also adjusted the valves when I did everything trying to get it running after 2years! of outside storage abuse. I set both the intake and exhaust at .005. They WERE almost closed completely!

I haven't really taken the bike that far since I have got it running, I mainly just don't wanna get stuck somewhere! hahaha So I can't say if the problem will stop after the engine gets hot :/

If the motor revs up when you cover part of the Inlet On the Air box that is prove that is is not getting enough FUEL and to much air. So turn the FUEL RATIO SCREW another half turn. Actually you should start it up let if warm up at least 5 minutes:

Then from the current setting of the FUEL RATIO scre Turn it 1/4 turns COUNTER CLOCKWISE and the IDLE SHOULD GO UP. Repeat the 1/4 turns waiting 10 seconds between each 1/4 turn to allow the motor to catch up with the new setting.

What you want is the HIGHEST IDLE when doing this. If after the last 1/4 turn the idle DOES NOT GO HIGHER or starts to DROP then turn the SCREW 1/8 CLOCKWISE.

I have done this process from another one of your posts, but will def do it again. I have also been thinking that, and have tried moving the notch on my carb's needle to ONE NOTCH UNDER MIDDLE
so as to richen the mixture. Otherwise I can't even get it to go down the road :/

[mikey34]

BTW

I have ordered a Jet kit for my carb, as well as a UNI filter, I figure it will make it harder to pull air through two filters(choking it?) like when I hold my fingers over it?

[Alleyoop]

Well the needle only comes into play after about 20mph that is when the diapghram starts to rise and allows more fuel to be sucked out. Your problem is starting off which is fuel is fed from the pilot jet and ENRICHER(WHEN COLD).

If you had to move the needle up for more fuel I would GET THE NEXT BIGGER MAIN JET. Do you have a FREE FLOW FILTER on it or have you done any changes???

But definitely turn the FUEL RATIO SCREW COUNTER CLOCKWISE so it sucks out more fuel. That is all that is wrong, right now to much air not enough fuel.

THANK YOU so much alley!

I have ordered a Jet Set and air filter. I will try tuning the screw COUNTER clockwise and see if I get a better take off. As soon as I get the jets and UNI air filter, I think it will make a big difference!

Thank you clearing this up! I did NOT KNOW that the diaphragm doesn't even move until the main jet kicks in!

So I am GUESSING, the Excellerator pump and the pilot jet get the engine up to a decent RPM, and THEN the diaphragm moves to open the main jet?

So I think its on the up and up! I sanded the body down also and took all of the emblems and names off the plastic and I am priming for paint. Should be a totally different animal when I am done!

Great, sounds like your on your way.

NOW I'm getting a little worried about the parts that I ordered. I DID get a receipt from them, BUT no tracking number yet(I ordered on thursday last week, its now monday) and the phone number given, no body answers. The website is "Scooterparts4less.com". Have you had any business with them? Or know anyone who has??
THANKS!

[Alleyoop]

Yes, I have ordered from them and no problems.

regret is always at the end....but good luck bro!

[mikey34]

Just got a reply from Scooterparts4less, he said Post Office is closed today, holiday, I will get a tracking tomorrow. So cool.

When I do get the Jet Kit, Alley what number would you recommend I try?
I rode it around today, and I have the Carb tuned counter clockwise, until the idle STOPS moving.
It sounds fine. But when I get on it, and try to take off, it will try for about 4 seconds, and then it tries to die. If I let off, it will idle and I can try again. Like this, I can pump the throttle and get going, once I take off it will do about 37, I still need to check and see if the ring is still on the drive-train but I don't Think it is. After I take Off a couple times, I noticed I can floor it and it take off with-out dieing, my guess is the Excel. Pump? and I'm getting enough fuel at WOT. IF this is the case, a bigger Jet should cure it, Right?

THANKS AGAIN

[Alleyoop]

The Main Jet:
If you know what size the current main jet is JUST put in the NEXT bigger one that will fix that problem.

The bogging at start offs:
Sounds more like your ENRICHER is causing the bogging when starting off IF this is happening right after you start the motor when it is cold. Try doing what your doing but let it idle for about 5 minutes so the ENRICHER cuts off the extra fuel and see if that eliminates the bogging. Then we will know its the Enricher that is causing the problem but only when the motor is started cold.

Will do first thing in the morning.

That is true about the MAIN JET...
IS there anyway to upgrade the Pilot? IF the Enricher is doing its job tomorrow, and is pushing in after it warms up, I might try a good cleaning again...

PS
Does the Enricher REQUIRE the battery? or does it come from the Stator?

[mikey34]

The problem that I am having with taking off, SEEMS to get better as the engine gets hotter...

So my next purchase will be another Enricher, I guess. See I just bought a new(USED) Carb from a repair shop, that didn't come with the Enricher. So I went back the next day, since my old one had different hardware. BUT I DO NOT DOUBT that he had no idea if it worked, or not either! haha

ON A BETTER NOTE: I Did track down my faulty switch(HIGH/LOW/FLASH) that was keeping my TAIL light from coming on as well. I will be sure to put this issue up in the Electrical part of the forum, because as you can imagine, I TESTED ALL bulbs, voltage at the bulbs, R/R, Everything, and didn't even think it could be not only a faulty switch, BUT I ALSO HAD THE MASTER LIGHT SWITCH(on the Right, next to throttle) SET TO "OFF"!!!!! Its hilarious now that its over, but I was HONESTLY about to RE WIRE the entire harness!
hahaha
