yelloscoot A question about your new tires, you have some idea of how weighed your rubbers and if the store where you bought em shipping you a box ? It is to know how much it would cost me the delivery if I buy my new tires in the U.S.A. for that then an agent in Florida can placement by sea to Venezuela. Currently is difficult to find new tires 13" for " La Orejona " in caracas. for some constrains that we have right now for our government..  .......no comments about it. I'm thinking to get the advice from JR , 120/70 in front and 140/60 rear, just scare me a little if they real fit my bike, Right now is 130/60-13 both tires, and the rear Kenda 761, is truly wear, in fact by the moment I had to rotate the kendas while I find new tires for her....Kenda is really UGLY, just last about 5000Miles ..... Thank you!

Awesom Job yelloscoot  indeed worth that upgrade, but the case is the OP7 Leds are a little pricey for me, I think that 35w H1 HID Xenon op7 could made me happy too  , given that mi bike come with projectors.. |

Yep when building power supplies for our Heath Kits in our youth my brother and I had access to an Oscilloscope which helped us see visually the impact the right capacitor had in smoothing things out. A lot of sharp tall waves resulted in flickering lights/video and warbly audio. Glow lights are only lawful as parking lights in many areas now so one does need to be careful. On the Malossi stuff die hard Aprilia modifiers are finding that stock variators with Dr Pulley Sliders in the stock wieghts give the best bang for the buck and easily last twice as long as the rollers plus the stock Piaggio variator lasts longer than the Malossi too. They are using the Malossi spings in the stock clutches too with great results. The gotcha with the higher speed engagement of the Malossi clutch many times is greatly reduced belt life and greater wear on the clutch shaft bearings inside the final drive gear box due to the harder hit when it engages especially if you set the springs too hard. The old adage usually holds true that when you make a candle burn hotter and more brightly it burns out more quickly so sometimes a bit of moderation is in order to get that balance of performance and reliability. Malossi is very good Italian brand, even better to replacing spare parts in Chinese Scooters, the CVT in this bikes really sucks, commonly this are made from Molten Zinc ( Calamine ), by example mine clutch broke bad at 7700 KM, given that I decided to upgrade my CVT completely to Malossi , this parts are made from Polished Steel , and what a difference  , not more Bike Shuddering at low speed and much better and lineal acceleration when I need it . I'm highly recommend to people with Chinese Scooter upgrade to Malossi or Polini transmission parts , and not is too expensive, dr.Pulley with original variation is also good one, but is matter of tastes and budgets. |

Very good advice JR, me neither like too much the 130 in front, 140/60/13 back sounds good to me , in my new shoes for this bike I'll try that 120/140, JR How many PSI do you use in each tire ? I use that bike every day with my Wife, commute home / work / home, and weekends go to beach  . Bye |

yelloscoot drop the psi to 32 and they'll feel a lot better. Do you have 13" tires on front and back? If so then you may want to do like I did on the next set and go one size bigger. I even on the back went a notch wider and it's smoother and looks neat!   JR Hello Guys, very interesting thread !!!, JR as always is a genius on scooters, congrats to yellowscoot for the new scoot, now : 1) I also have a similar model rocketa MC-79-250, mine is skygo executive 250, I would like to install a givi windshield, this model D210ST Will fit my Scooter ?  2) The tires size on mine are 130/60/13" both, JR mentions that one could one size bigger?? what is this size ??  change the oil just 4 times on 8 years is first time the I've hear that...amazing , I keep changing dino oil 20w50 every 1500km =). Bye |

Hello guys, greetings from Caracas, I'm having some problems with my front suspension, it goes to the bottom when brake the bike and when I'm in rough terrain badly, then I wonder if it will be enough are just get all the Chinese oil and put a good oil 15w as Motul Fork Oil My bike is similar to the Roketa MC-79-250, I would like to know your opinions if it is a good way to just remove the hex screw from below and above the forks, without removing the entire front forks could work for me. this are the photos of the hex screws. Screw top Forks.
Hex Screw bottom Forks.
The forks:
Thank you !

The Piaggio bike are scheduled for oil changes every 6,250 miles if you use the recommended 4T Synthetic MC Oil or up to twice a year the way I ride while my Lance 150 had its oil change schedule listed as every 500 miles. I went from 24 oil changes per year to only 2 and the Piaggio engine in my Aprilia takes about the same amount of oil as the Lance did. With the Japanese and Italian designs you get tighter tolerances and a full flow oil filter instead of just a screen which extends the time between required oil changes. The oil pumps in the Chinese bikes do not have enough capacity to support a full flow filter so they only have a screen for the most part. Discussions about putting synthetic long life oil in a bike without a true filter are really moot since all the dirt and carbon will be recycled through the engine by a high detergent long life oil keeping all that corruption in suspension potentially doing more harm than good. Anyways if you are a daily commuter who puts on 500 to 1,000 miles a month a Chinese bike requiring 1 or 2 oil changes per month may not be the best fit for your needs. You have to consider the difference between low cost and value for each individuals circumstances. Some who ride recreationaly or seasonally and may only put on 500 to 1,500 miles a year would be a good fit with most Chinese scooters however the 6,000/12,000 mile per year rider really needs something better suited to that usage. This thread has been well discussed =), so 24 oil changes per year just 2 changes a year, that definitely pays off !!, but here in Venezuela today by government policies (Socialist..... ) is quite difficult to buy good Japanese or Italian bike, those kinds of bikes are only for police and the armed forces, I mean KLR Kawasaki and Suzuki Vstrom..., we have several constrains, so we do not have no choice but to ride bikes Chinese  Additionally here in the Caribbean temperatures they are usually high 25 C to 33 Celsius degrees, in the months of November to January, down a bit to 16 degrees Celsius Maximus, so the recommendation here use 20W50 oil for Chinese motorcycles. Bye! |

Yamaha specifies 4T for a reason as do other major scooter manufactrer. I called the engineers at Piaggio and asked they why and was told it has to do with more than just wet clutches. Greater resistance to foaming and coking from hot spots are some of the additional considerations along with the higher rpm range that most bikes run at compared to automobiles. On a new Piaggio if they have to warranty an engine they will analyse the oil in it and if they find its not 4T they will deny you compensation and void your warranty. You have nailed down the point! and also I agree with Piaggio / Yamaha / JinLang engineers this matter |

Thanks rockynv / scooter, Yes I need to check the variator and rollers, it has been a nigthmare for me to dismounting the variator , The nut is ultra tight , I don't have a Impact Wrench, is too pricey here, I just have a Locking Chain Clamp and Universal Cluth holder...maybe I need some vitamins to finish that job , LOL. |

I can't see why a 4T oil is necessary, if a wet clutch isn't involved. Any 20W/50 should be fine.....especially when you are changing it at a 600 mile interval. I use the same 1000 km, (620 mile) change frequency, and I won't even waste my money by using a synthetic. I don't leave it in long enough to make it cost effective. Dino oil....a heavy duty diesel variety, is good enough for me and my two wheelers. In your climate, I would probably stick with a 20W/50.....but it would be a conventional one. If synthetics are your thing......there are a number of brands offered in 15W/50....as well as 20W50. Either would be less expensive than the $10 to $11 dollars charged here for one quart of 4T oil. Hello HillBilly, Very nice bike your BMW R1200, a Beauty !, well the owners manual for my Scooter says that SAE 20w50 4T - API SH, and yes is true a wet clutch isn't involved, now here in Venezuela the conventional oil for a car 20w50 cost the almost the same for bikes, sometimes one could find very good 4T Oil Mineral ( JASO MA Certified ) even more cheaper about 2 - 3 USD $ ( 290 Bs ) for 1 Quart Bottle, now considering this 250cc scooters engines run much more hotter, I would prefer keep using 4T oil than conventional, I've read in that a lot of folks in the USA ( Bobistheguyoil Forum ) use with success for their bikes Shell Rotella triple Performance 15w40 or Rottella T6 5w40 that is JASO MA Complaint, and this is for diesel/petrol.. Than you. |

When do the vibrations occur most? Hello, the vibrations begin hard at first when I start the engine, after 7 minutes warm start begin to soft ,and also when I go between 10-20km/h ( 3000 RPM ) shake also, the clutch is new, but the bands on it I review are a little thin |
