New Pegasus-performance problem

Bob the problem is he is a ways away from CBXMAN where he bought it. Gary because it worsens as it warms, has anyone looked into the choke (which I am unfamiliar with on the Pegasus) ?

Hey Gary- let me know how far you are from Hershey, PA.

CBX will be calling me at some point to tell me that mine is done.

I've borrowed a snowmobile trailer to pick it up- maybe we can take yours up there and bring mine (or both) back down!

I know I'm not next door to you, but maybe we can work something out depending on distance, and when everything will be done.

Besides, It'd be cool to have two Champagne Pegasii on a trailer in back of my Jeep Commander that is the same color! Take a good pic and sell it to Jeep!!! And QLink!!! Man, we'll be rich and famous and....... (I can dream, can't I?!)

Well in my troubleshooting mode, based on what you said above.
Check to see if the rubber intake tube to the carb from the air filter came loose. The engines run extra lean from the factory, so if the air intake frees up, the engine leans out way too much to run. In my case the rubber tube came loose right where it plugged into the air filter box on the bottom, you had to look hard to see it.
if the intake manifold is leaking allowing air to get sucked in it can do this too. One person had a huge tear or crack just under the clamp in the rubber allowing air to leak in.
if the diaphram on top of the carb is got a hole or tear in it, it can do this too.
Look for kinks or loose or cracked vaccuum lines.
Make sure the fuel tank air vent is working OK. You can loosen the gas cap and test ride to see if that does anything.
I have had a couple of ignition coil units start to go bad in this very same fashion. Someone else had a CDI unit behave like this as it went bad. they just don't make decent ignition coils for these scooters now. You can't tell if you are getting a good one or a cheapo counterfiet or something.
The spark plug wire goint between the plug cap and the coil sometimes isn't in and screwed down tight, or the plug cap has loose internal, metal parts, this leads to higher voltages that cause the insulation in the coil to break down fast. Even more so if the insulation is of substandard quality.
I buy extra ones so I have spares on hand while out on the road. it sure helps to have them on hand for troubleshooting.

I was able to load mine up in the back of my Chrysler Town & Country minivan, minus the mirrors and top box. Fit well and the floor seat brackets make great anchoring points for the tie down straps.

Really Bob? Man when I measured it was like 8"+ too low headroom entering the tailgate. The best I could figure was that I could slant the thing going in then stand it upright.

What year do you have?

I was asked to try one more thing before arranging return of the scooter. Take her out and run it like I stole it. Go baby go! A good mile or two full open. ;D !!!
I hope it's not a defective clutch. Am taking cell phone, tow truck number and Visa. Don't ride far without it. Will let you know what happens.

I think you are right on there Gary, I am no mechanic at all, but I have been around every type of combustion power plant you can think of, I have owned and flown 4 planes from a Citabria to a King Air. Currently own two Bell Helicopters (turbo jets), the normal gaggle of four wheelers and three motorcycles. On my first scooter at the moment! Regardless of what someone is telling you, the behavior of your scooter is NOT NORMAL, and is not going to fix itself. There is one way to determine, at least narrow down the nature of the problem. If you were to swap out the engine (engine only, keeping all the electrics with the original bike) with an identical scooter, the matter would be identified as to nature. I don't think that is a step the dealer folks would do, but it is a practical step, the 'shoptime' involved would be minimal compared to pulling every component and testing stuff. Sorry to run on, but I agree, it is time to get this resolved, and hopefully that will happen for you!

My Pegasus came with an NGK plug,and they are not junk.It could still be a bad plug though.

What does the plug read look like? I agree NGK makes good plugs, but others on this board have had problems with them, like any other plug, at times. Napa Auto here in Texas carries the correct plug. Buy a couple regular plugs at $3 each and try them. My bad chinoplug would show good spark when removed and connnected to the plug cap, touched to the frame and engine turned over. But it failed at speed after warm up. If the plugs a black, wet read, then its not burning all the fuel due to spark failure.

Guys ; Let's slow down and back up a little bit. It is an NGK plug (DR7EA-9) as per the manual. It's nice and dry, no discoloration. The gap is correct. No visible cracks. That does not rule it out. The coil, plug, CDI, any electrical part, even a connector can have an intermittent failure at certain temperatures. That's one reason why I wish I had some known good parts.

I have cleaned the carb and jets, drained the tank and refueled twice, ridden with the gas cap loose for venting, checked for good fuel flow to the carb. Everything looks good. That does not rule out the carb; could be a bad casting. These things are rare but they do happen.

The most important thing is; I'm in contact with CBX and they are making every effort to get the scoot right. They will send me parts and/or come and pick up the scooter, do the repairs and return it. The warranty will remain valid even though I'm doing some work on the scooter .

I now have 180 km. of good wide open riding. I'd like to double that even triple before having to return the scoot. I'll talk with CBX on Tuesday and get their input.

Question: could a slipping or chattering clutch cause these problems?

Thanks ,Gary

Take a trial run with the air cleaner off, this can help detemine if it's a air/fuel problem, and see what happens.

Hi Bob,

To the best of my knowledge, CBX is not going to charge me. Believe me, the idea of having them pick it up and return it has not been ruled out.

I'm kind of new to scooting, and I guess it has become somewhat a quest to figure this out. As long as I have the support of CBX by staying in touch with them and knowing they will fix it, I'm not worried. In fact I'm enjoying the work and gaining a wealth of knowledge. I'd never even heard of a CDI till a week ago.

The good news is I tried the different CDI today and it made a world of improvement. I going to hold of on judgment till I ride some more, swap parts back to the original scooters and try running it without the air cleaner as "whodunit" suggested. That will be a quick ride. I'm a little nervous about that one.

Thanks, Gary

I'll be able to update tomorrow after the football game (Ravens) and a good long ride on both scooters and combinations of CDI's.

Like the college motto from the movie Animal House: "Knowledge is good".

From what I've been reading in different threads, getting this CDI could take 2 days; could take a month. Who knows?

It wouldn't hurt to have a spare. Are 50cc through 150cc CDI's more or less generic? I'm thinking of buying one locally but need help. Most of the scooter shop personnel around here:... well.. let's say I wouldn't trust them to change the batteries in a flashlight.
