Bonjour j'ai un tornado utility 250cc injection 2015.J'aimerai savoir si vous aviez déjà entendu parler d'un problème qui suit. La machine part très bien . elle roule numéro un pour 20-25 minute puis elle s'éteint. J'attend 1 ou 2 minute et elle repart très bien pour un autre 20-25 minute. Elle a 865 kilo alors comme neuve. Ne prend pas d'huile , ne chauffe pas et tout les filtre changer .On parle sur les forum de la bougie quand elle vient chaude elle coupe l'étincelle ou du tuyau et bouchon a gaz pour que le réservoir prenne son air. Tout ca a été vérifier et cest ok . l'injecteur fonctionne bien car il va tres bien avant qu'il n'arrête . il me reste a vérifier si il y a du feu aussitôt qu'il éteint a chaude. J'attend votre avis svp . Merci

Great video as always even though I've watched it more than a few times. You didn't state if you need to put pressure on your piston stop tool like if it was torqued down so there's no deviation with TDC. Oh one thing what size were your spacers in know it will very with each engine.
@49ccscoot 2 күн бұрын
The piston stop needs to be tightened so it doesn't move. You shouldn't put much pressure at all on it to stop the piston. I don't recall what spacers for the one shown. The stuff that comes with the Summit kit works on lots of things.

Hey . Thanks so much for. I did tires but not on scooters and ive been dealing with them now for gas savings purposes and the fun of riding. I was about to take the tires to a tire shop until y saw your video. Men oh men that was a breeze. I custom built my ride so it took me less than ten minutes to remove the tire. I had the front one which is in almost new condition so i swapped the valve that was leaking and the tire . Cost= $6.00 with new valve and air from the local gas station that it didnt work but i used a compressor that a built from different parts and it work . If it wasnt for that it would have been $3.60. Still I didn’t waste the other amount cause i needed air in my wifes car too. Ok amigo gracias 🙏👍👍

hello brant, great report, tested very well. I have the same components in it and the speed display is short. I don't have this with the old Malossi Vario, does the belt slip or why is that like that? Did you install the original belt or the one from Malossi x Belt Kevlar? Kind regards, Nello
@49ccscoot 5 күн бұрын
I've just been using the Yamaha belt. When you say the speed display is short, do you mean the way it doesn't show speed till it's already moving pretty fast? That's some sort of issue with the speedometers on these. All of them do it to some degree from what I've seen (at least older models). If it were belt slip, RPM would increase and you wouldn't be accelerating. If you mean it's not going as fast, then maybe you have an issue with roller or slider weight, the belt is worn too thin, there could be slip or some other CVT issue. Observing RPM would help. If you want it to go fast, then RPM needs to be around the powerband.

@@49ccscoot First of all, thank you for your quick answer, sorry for my English. In your video at 12:30 min, the speedometer stops briefly at 20 and 40 or slows down and only from 60 onwards does it rise evenly to 100. This is also the case for me when I mount the Malossi Vario MHT Next with 16 g weights. If I put the old Malossi vario on it with the same weights, it doesn't work. I took different measuring points on the road, the scooter runs the same speed with both Varios, I think if I didn't have the misfires on the speedometer, I would be faster in acceleration with the new Vario from Malossi until I reach the different speed at my measuring points on the street. The speed increases evenly, it doesn't increase briefly as if the belt were spinning. I have the 2011 model, so I think it has a new speedometer.

@@NF-ze2fo I don't think it reflects anything happening with the engine and CVT for most of us. Your case is an odd one. You can see videos of people with all sorts of setups and the speedometer is unresponsive at low speed when accelerating hard. The speedometer is electronic, so I assume it is a form of lag.

The proper way to port match is to assemble the case halves to the cylinder. Then remove only one case half, this will expose the case to cylinder porting. Blend those ports, assemble the other case half then remove the first case half you just modified. Blend the second case half to the cylinder. Also, assemble just the cases together and blend them to each other. You may need to use dykem (sharpie) for other ports depending on the design. Do not base the port matching to a gasket. Match the components, then modify the base gasket to fit your engine.

Hey Brent! I have a quick question, what is the optimal temp for a liquid cooled racing setup. I have a S6 R/t with an 80°C water temp. The problem I had was the piston seezed just from the two sides upper from the pin area. Was the overall water temp too high? The carb was tuned for rich for sure, it wasn't lean what I was seeing.
@49ccscoot 12 күн бұрын
Mine runs 120-140F mostly, so 40-55F cooler than 80C roughly. Some bikes have thermostats that try to keep them hotter than that though. That shouldn't cause it to fail on it's own. It may be hot from ignition timing or something else in the setup. You can try to verify timing with a timing light to make sure it's where you think it should be. Definitely make sure squish is set to spec. Good oil supply... I run mine 4oz per gallon or 32:1.
@pepelazy3249 12 күн бұрын
I don't have a thermostat. It's a racing engine too. 70cc 26pwk carb, 115main jet, 32 power jet. Stock ignition with a top performance cdi with a different pre ignition as I red on the manual. Squish is a bit bigger than the factory specs, about 0.1mm bigger If I remember correctly. I use motul 710 racing oil. 1:33. Carb tuning can be off, I might try to take out my power jet and tune it only by main. But if Im honest, I couldn't really tried full throttle spark plug checks, I used my scoot mostly in the city, this happened on my first longer high speed ride. But thanks for your answer! I'm looking forward for any more tips.

@@pepelazy3249 I've taken mine to an industrial park before on a day when most businesses close. It had a long enough road for me to do 1/8 mile runs and slow down. Carried main jets with me and the tools to change them. That was the quickest that I've ever gone through a range of jets for tuning. I use a dragy and I film my runs with a helmet cam that sees my gauges so I can just do the jet runs and then analyze later, but you don't have to have all of that. Dragy has been a great tuning tool for me. Timing from video before that was consistent, but the dragy is amazing and gives more data instantly and very accurately. It can't tell you if the tune is safe, but you can see what works for power easier. Generally a step richer than peak performance is a safe enough tune, but sometimes it gets tougher than that. dragy : amzn.to/3Rxm2Lb (affiliate link)

And from what I have seen in your carb tuning videos, you have problems too finding a jet that works perfect in lower and higher revs too. So I will take my time for this, it isn't a fast process.

This video was perfect I am trying to figure out how to make my own leak down tester and this video really helped me understand how to do it myself. Very clear, and well to the point. Thanks so much for making a video a rookie could easily digest and walk away from not feeling so much like a rookie. I am not sure I have taps large enough for those threadings but I will either pick one up or just use JB weld as we are only dealing with max 7 PSI. Should be able to rig something up like that all half assed and still get the job done because of such low pressures. My biggest question for me right now is how I am going to administer the air into the engine. I really like the hand pump but not sure I will find one locally although I'm sure harbor freight has something of that nature. A Schrader valve does seem kinda nice but also so does the hand pump. we shall see but regardless thank you for such a clear and to the point video. I ride old 2stroke mopeds.

With HF and Amazon, taps can be acquired pretty cheap. If you work on much, they're likely to come in handy at some point in the future anyway. JB prob works OK for this, but it may be similar cost to get a tap vs JB.

Since I hit the deer and with I guess diabetes related complications, I get more sore than usual riding longer and don't bounce back from a long day of riding well. Plus I'm too broke to do it. So the idea of paying out more than I can afford to be miserable for a week doesn't make a lot of sense. I tend to think of it as, I can either continue to ride and mod my scoots or I can spend all my money on a week. The small bore rally last year was the first vacation I've taken in 20 years, and only possible because I split everything with Ryan.

Hi Brent, came back to this video hoping you would mention it but haven't. That "special" bearing, does it really need to go on the CVT side? Or can it also fit on the rotor side? I find it more convenient to put it on the rotor side to swap ignitions quickly, but im afraid it wont fit and just got a fresh set of bearings ... I have a C-One (70)cc and it had 2 regular bearings in it.. Now when doing an upgrade, the bearing on the CVT came attached to the crank... Would like to leave it as it is and put the other needle bearing on the rotor side, what do you think? Looks like the crank has enough space for that center piece of the bearing but idk.. :/

Saves some time tunning. Or just to see the differences between them (those that are not programable or have different curves to select).

@@joaomelo61 That's what I figured. I guess that would save time if the engine is out of the scooter. I'd think if it were on a chassis dyno, bolted into the scoot, then it would probably be just as quick to swap the ignitions the traditional way. My MVT DD for Piaggio and Minarelli didn't use a keyway for the rotor so you have to set that up anyway. At that rate, you'd need a 2nd crank and the bearings as intended so you could pull the crank and ignition side case half all off together.
