Renamed: Scooter Won't Accelerate / Start By straightbangin (Read 23,988 times)

There's a support for the near side of starter shaft in the cover that the kick start lever is on. That probably needs to be in place for the starter to work properly. The small toothed gear engages the larger toothed gear by shifting position, but it may not work when not aligned by the cover.

I help a Mother and her son months ago and I finally got them up and running. The mom was doing all the investigating and fixing for her son. She did a fanastic job, just like you she did not know squat but she dove right in and just kept asking questions taking pictures and videos like you have done. Well anywhos I was trying to find that thread It was on ScootDawgs forum because she was holding the BENDIX SHAFT UP while her son started the scoot and she took pictures of it. Just to show you that it can be done BUT it needs another pair of hands.

This thing, when it starts, what RPM's are you getting up to? If your variator is jammed it would go immediately to redline and die out from the rev limiter. It would never get a higher gear ratio. How many miles are on it? The belt didn't look worn. The variator looked as it should. If the engine isn't attaining high RPM the variator will not spin the clutch fast enough to engage. If you get all that stuff spinning with no cover on make sure you wear safety glasses it should idle at 2k and run at 7k any little chunk coming off that belt could cause an injury. I think your'e barking up the wrong tree.

Don't keep trying to engage the starter without the cover on or you may overheat the solenoid coil that causes the small gear to shift position and burn it out. That might induce another problem. Put the cover back on. Why don't you use a jump pack on the battery terminals or jumper cables to a car battery. It doesn't take much to mess up a battery so that's probably the easiest way to verify a problem. If the engine won't turn 4K your'e not turning enough RPM's to actuate the clutch anyway. From your'e previous posts it doesn't sound like your'e getting enough RPM's to make that work.

radford, true, I was looking at the inside of the cover yesterday and saw how it supports it all

Alley you showed me that video I saw how they did it, I think she ( or he ) was holding the back side of a screw driver to the bendix to support it / keep it in straight. I've pressed against the bendix a little while it was running once before and it seemed like it would be hard to keep a screw driver on it, it was a pretty forceful turning item. The piece of wood sounds better to me, would be great to find a little 6" x 6" piece of wood.

radford i dont have a tachometer on my scooter so I dont know what rpms it gets it up to. All I know is when its enough rmps to make the scooter move where its parked it will drop if i dont let off the gas. It has like 600 miles on it. I bought it in July, new and it started giving me crap at 180miles!

ya know, that very part could have shorted out from the rain storm so that could be what is wrong, but not sure if it would start at all if that was the case, something to go on the " hmmmm list " I don't have a jump pack. I'm trying to spend as little as I can at the moment. I'm just starting to get back into work after being out forever from car accident injuries so money is no bueno at the moment. Between the tools and parts ive needed so far for the scoot im prettys spent. Thanks for your help/suggestions.

Its 8:22am here in Miami Beach, I have an appointment at noon, so I don't want to get dirty before then, it should be blazing hot this afternoon so I'm going to start messing around w the scooter around 4pm or so, will report back to you guys then

Raford3,
I think your missing the point here, the motor revs up but does not move the scoot then starts to bog so she backs off the throttle to keep it from dieing. That indicates something is binding in the CVT or Rear Wheel. If the Clutch Or Variator are binding and not allowing the belt to move up and down freely IT WILL BOG YOUR MOTOR DOWN it will NOT REDLINE.

The woman is looking for help and suggestions on what could be the problem. Don't want to get on your case but Barking up the wrong tree does not help. If you think or believe something in the CVT is NOT the problem what do you think the problem could be.

Variator weight gotten sideways?

[raford3]

My thoughts are, the rain was coincidence that had no effect, the scoot has another problem. In the position the variator was in it would idle w/out engaging the clutch. If it was jammed it probably wouldn't engage the clutch at high RPM. If it was slipping due to moisture it would quickly dry out from the heat of friction. I am assuming she means the scoot will idle when she says Rev, from her posts I am working on the engine RPM angle. No offense about barking up the wrong tree, it's a fairly common expression due to an abundance of coon hunters in the Richmond area. If she can do another video showing an attempt to take off it would be helpful. I had a problem on one when the tube between the filter element and the carb had become disconnected near the filter box. It wasn't readily apparent on inspection, but caused a similar problem, I think, if I'm interpreting "All I know is when its enough rmps to make the scooter move where its parked it will drop if i dont let off the gas" means it bogs. Anyhow, that's where I'm coming from.

I'm now trying to visualize how a variator weight could turn sideways as it rides in a channel where there isn't alot of spare room. I think the thing has very few miles. I would give this posibilty low priority.

I've had it happen. Though, I had more than a few miles on the scoot.

I am also going by what she says it REVS but will NOT move the scoot , that I believe points to something in the Drive Train binding and holding the motor back making it Bog and want to die unless she backs off the throttle.

Shannon,
if you can start the scoot on the Centerstand and EASE UP ON THE throttle and VIDEO the Rear Wheel that will let us hear the RPMS of the motor and see how the rear wheel is acting and about what RPMS it starts to bog out on you that would help. Seeing as we cannot see the CVT and Belt in action.

I just put the battery on the charger since it sucks a$$, especially when not being able to drive it to charge it up.

While its charging I want to play w the belt/variator, what should I be looking for/testing?

Once its charged I will try to start it so u can hear what it does w/ a fully charged battery (ill film it all this time from full charge to trying to start, etc..) and then I can also answer

Well you can try and rotate the variator with your hands to see if it turns and the belt moves along with it. Then put the cover back on and see if its starts and then let it warm up a little and then try and ease up on the throttle and VIDEO THE BACK WHEEL so we can see the wheel and hear the RPMS go up as you twist the throttle easy so we can see if the wheel is spinning faster and at what point it start to putter out.

[straightbangin]

heh, thats IF i can get it started Ill go try to rotate the variator now and see if the belt moves too...

[Alleyoop]

Cool waiting for any info you may have.
