Wow Dan, you've done your research that's for sure! I was unaware that the B case wasn't made. That makes sense. One thing tho, my scoot is a DC fired coil. I haven't checked my stator yet so I do wonder if it's an 11 or 8 pole... I'll for sure be pulling the fan off tomorrow to check. I have tried to research these engines to the best I could, but the availability of information is sketchy at best. The problems are, because the parts are manufactured in China, most of the literature is also in Chinese and from the way things appear, the Chinese aren't big on translating their documentation into English. I have tried contacting Bintelli (about 4 four times) trying to find a parts diagram of my engine. I have also emailed the Parent company of Bintelli, (Road Rat Motors) seeking information and neither even bothered to respond... My Havoc is is awesome scoot, I feel like the manufacturer of my scooter isn't worthy the quality of my scooter. If Bintelli got into the game and made parts available (direct to customer) and published info so people could get the right parts, they truly are scooters that you could keep going for a LONG, LONG time. I've had a lot of scoots in my day, but none the quality of these Havocs. So, most of what I have dug up so far has all been 2nd hand info published across the web. On that note, take what I say with a grain of salt. The line I replaced was not damaged from impact or anything like that, it was dry rotted and in several spots there was leaks. This is not something new. However, the scooter runs near perfect, unless you hit it at WOT. I don't know how these scooters work on that level... All I know is the line was dry rotted, with exposures and needed to be replaced irregardless.  The Mikuni Pump should be here monday, so Im hoping one of them fixes the issue and the MiKuni is going on anyways... I'm wondering if I should re-route fuel lines also (to reduce how much the pump has to work)...... |

Yes shorten the fuel hose from the pump to the tank will help, if gas is hard to get to the pump the pump does not have anything to pump to the carb. If you can at least have the pump level or a little lower than the fuel outlet from the gas tank. I think on yours the fuel outlet is on top of the tank which means the pump has to do TWO things suck fuel UP from the tank to the pump which is mounted high to boot then pump it to the carb. I have seen these types of setups having problems keeping fuel in the line from the tank to the pump. You normally want the fuel outlet on the tank to be on the bottom then it runs nicely to the pump at the same level and up to the carb.

I don't relish the thought of poring through documents of changlish to research this, so thank you for doing the leg work for me. I'm not saying that line on yours wasn't a problem just that the problems that occur from this line being totally off are present regardless of throttle position. At least IME. As for rerouting the lines...it couldn't hurt but do me a favor. In the interest of process of elimination, hook the new pump up first and see if that helps. If not, then try moving the lines. Last thing I would like to try is to relocate the pump closer to the carb. I won't be able to do any testing of any sort until next month when I get paid again. So I'm watching what you do to figure out what I need to do. |

A good source for Information on these scooters are Chinese sites like Alibaba.com... However, do not be lured by price, service and quality is bottom of the barrel.
I looked all over the web for information about my stator/magneto... Finally found some info on a Chinese site that google translated. My 12-pole DC stator is only 120 watts! (Yes I know stators only produce A/C)
I will. My first step is to test it as is. Fix or no Fix, the Mukini is then going on.... If Neither the Vacuum Line repair or the Mukini fix it, next step is either a fuel pump or gas tank relocation (Switching to gravity).
Also, I will for sure keep everyone updated. If we figure out the problem, were not just fixing our scoots but also everyone else who reads these threads and has this problem.......
I somehow screwed up my post quotes... I put my text in bold.... |

dmartin95 I don't know man...further discussion with some more mechanics and the common consensus is that our problem stems from a loss of vacuum at WOT, that combined with the fact that our pump has to pull fuel up and out of the gas tank then up a foot or so then push it to the carb, our fuel delivery system is just flawed all together, and nothing short of moving the gas tank or adding an electric pump, is going to solve our problem. And now I just set a personal best for run on sentences. My fingers are crossed that the better pump will solve this problem but I have my doubts. Good new is that the option of a small 4 PSI or so pump in line before the stock pump is another alternative that's been tossed out there as a suggested fix. That would be really easy to do, wouldn't put to much of a strain on our electrical system and the stock pump would act as a regulator.
