it's true I see that it's tricky for a good fit of the cylinder with the pistons and its segment., it doesn't always work from the first but it's the very important step for the longevity of the engine.
I love how you show the full job step by step on video! Can you please tell me how to correctly replace the rear wheel axle bearing? Should I use a heat gun or should I press it?
I have 3 scooters under repair, Kymco agility naked renewed 2017, Kymco people 2005, and ksr toxic 50. the ZIP I would like to add it to my collection as well as the Yamaha booster and aerox
You are professionnal ? Me iam old years 17 aprenti practice with contrat , echec abandon after 25 weeks , contrat abandoned from Yamaha dealer belgium , 1995.
Здравствуйте уважаемый мастер, снова я нуждаюсь вашем совете. Как вы уже знаете у меня sr50r. 2t. Замена первичного вала и вторичного шестерни какой вы паставили малосси размер? Я перехожу на 70куб.спорт. И хочу удлинить передачу. И паследний вопрос ещё есть сток6 или малосси лутши? Огромное вам спосиба за вашь труд и терпения от диваных икспекторов. Добра вам у удачи. С уважением к вам Сергей.
Is it normal for the input shaft to have some play after changing the bearings ? It moves a little when you shake it, but like 1mm. The bearing shouldn't been damaged because i was really careful. Also I am with the stock gears, I have some whining sound, could that be that they are worn ? Visually they don't seem that much but who knows. Otherwise great video !
Nevermind, I just found out that the previous owner had installed a straight cut gear, and didn't realise it. So no problem at all, except it's little annoying 😁
hello, what belt do you use and what size? I noticed that it is malossi but the size is not visible in the video, and a link to a belt would be very helpful
i saw the primary gear has some play once assembled, is this normal as mine had this even though I replaced the bearings and saw the bearings had some play. but some people say there's meant to be zero play? :( help
i am trying to change these gears on the piaggio zip 50 and the cover is extremely tight and stuck. does anyone have any advice on how i could do this because i dont think wiggling will do much since there are also those binding pins in the cover?
could you perhaps recommend what gearing i should get for my gilera runner with an airsal sport 70cc a polini cp19mm with a pod, multivar 2000 vario and polini g3 clutch :D
hello, just wanted to ask about theese gears. i have put on my aprilia sr 50 euro 4.. afther 50kmh they are really loud.. is it normal for them to sound like this? i wanna knoe if theres by any chance to lower the noise from the gears?
Hey, I have a Euro 4. It's fully derestricted but only top out on GPS at 74km/h. I've heard that the Euro 4 models have a short secondary gear compared to older models. DId you see much speed increase after you replaced the gears? Is your bike de-restricted?
i did this a few days ago, went pretry smooth. the only thing is that i fitted a new seal and i didn't install it to be flush with the gearbox cover. will this cause any problems with the bearing?
i don't understand on video on gearing states this gear will slow bike down and have less top speed yet your fitting it on this video you state the malossi 14/39 gear is not suitable for the aprilia sr 50? video do you need more speed
No, but I understand your confusion. The Scooter Street video was done with the gears from a Zip/Vespa which are to suit smaller wheel. Smaller wheel needs more rotation for the same speed. The 14/39 is the correct gear set for the SR, but not for the Zip - this is the point I was trying to make.
I definitely would not play with the diff gears with the factory cylinder still on. On some scooters the factory diff gears are a little undergeared from factory, so an upgrade works well even with the factory cylinder (the morini engine in the Ditech SR and TGB/Pegasus models is a good example). With the Piaggio engine, you will lose a significant amount of acceleration, and likely not gain any top speed. The limiting factor of top speed is lack of power vs wind and road resistance. You need more power, not more gearing.
I had the hiper2 engine codes committed to memory, I've since forgotten.. the gearing system is the same on all, the only difference is the ratio (tooth count) on the gears, which varies depending on wheel size. Short answer, yes it does apply - just check the teeth on the factory gears to make sure you're moving in the direction you want to when you order the upgraded kit.
Hard to say exactly as it needed some more transmission tuning after, but gained an extra approx 6-12kph depending on what rollers it was run with. It gave the bike a fairly big torque increase at 60kph onwards
@Scroatal Octopus I have experienced a pretty decent fuel saving on the bikes I've installed one on. I'd probably recommend a 10-15% increase though, no more. The acceleration will reply suffer without significant power upgrades
