Heres a pic of what things should look like under the cover. (yes Im being lazy tonite and attaching photo) When does it make noise? when your idling or when your moving? -Zug Yeah, I also posted a video show the CVT in action; it is my last link. |

That's awesome that you got all those radiators. It ain't gonna overheat. Sounds like the belt's too big, maybe an 872 22 30 would work. The newer models went to a single radiator. The older models with 2 radiators had the heating problems. I believe Zug has one of the newer models with one radiator and has had no overheating problems. Good luck with your new scoot, tk3000. We will be waiting for any updates. BTW, the single radiator systems like on the Reflex clones hold about 32 oz of coolant. Thanks, Cruser, I will be posting often about all the developments. As far as cooling system and radiators goes I flushed the system a few times (with a hose, with coolant and water to help eliminate and reminiscence of corrosion, etc), and I believe that I eliminate any old coolant from any hidden and lower spot. I also eliminate any air in the system with the engine running and radiator cap off, and even with the engine running for a few minutes (and sporadically slightly opening the throttle) and radiator cap off the level of the coolant did not change. But when I said 20oz I did not take into account the overflow tank; I still have to add coolant to the overflow tank (I need to remove the side panels in order to remove the overflow tank and clean it properly). Anyhow it is possible that the new coolant that I also used to flush the system took some hidden spots and lower spots, so can not say for sure it is 20oz. I still did not look into the dual radiator system, but initially the idea would be that a dual radiator system would provide a much more reliable, effective and fault-tolerant system (if one radiator fails, there is still another one running [backup]). |

Incursions in the 250cc World... About 2 weeks ago I ordered and received a 250cc motoscooter, an old stock (2006) chrome storm 250cc edition. I have had a 2-stroke turbo since 2005 and a gy6 150cc phantom clone since 2007, and have done pretty much all possible types of maintenances, improvements, and repairs in my bikes and other vehicles that I own. I received the documents (certificate of origin, etc) the following day after having ordered it online: it came via UPS Express; it wasn't really necessary (I could have waited a couple of days), but Kudos for them for that! At first the bike simply would not start (motor), but after having removed, adjusted and cleaned the carburetor (it had carbon deposits in the floating area, etc) the bike would start just fine. Overall the grade of the parts in such bike seemed to be above the average (better grades for fasteners, nuts, etc) and by all means better than the ones found in my roketa 150cc. I changed the engine oil (which actually was rather low) and gear oil, drained the old coolant and flushed the system a few times, and then replenish it with Prestone (yellow bottle) with the ratio 60% coolant and 40% water; I was able to fill the system (dual radiator) with about 20 oz the coolant mixture (does that seem to be the right amount?). The only current issue is related to the CVT, it seems that the belt is somewant loose, rattling, vibrating and making contact with the cvt cover (the CVT cover gasket is not loose and is actually glued to the cvt cover itself). I only notice such annoying noise when the CVT cover is on, so it seems that the belt is hitting the CVT cover. Any insights about the CVT noise issue would be appreciated. Below are some pics of the bike and at the end a video showing the CVT in action: Frontal radiator in a dual-radiator system:  Lower radiator in a dual-radiator system:  Carburetor view:  CT Motor 247cc engine top view:  Decent amount of under seat space:  CVT Video: The following is the belt installed in that bike: "First-Car Belt V-09" number 915 22 30. Two flaws noticed were: 1) it does not have kill switch which seems even more essential in 250cc considering its larger displacement; and 2) it does not have a temperature gauge, only having a warning light in the instrument panel that I assume would turn on if the engine is getting too hot or about to overheat. |
