Harley Davidson is out sourcing to China to have motorcycle parts built cheaper. It also is funny that one would think, a Chinese scooter is a cheap machine. That one can't get parts. See, my scooter is a direct copy of a Japanese scooter called the Honda Foresight 250. The only difference in body style is the headlights. Mine has 2 lights and the Foresight has 1 light. The Foresight was never marketed in the USA and only made for Europe and Asia. So we could not buy body parts through no one else but Roketa. The engine is more interesting because it is a CN250 engine made by Honda for the Honda Helix engine. So many parts are interchangeable with the Honda Helix. Even had a Honda Dealer say he would work on my scooter. But I do all my own work, with exception of changing tires. Honda has a machine that does it, so does not bend rim. But many of these scooter engines are copies on Honda engines. So like I could have bought a starter for my scooter through Honda, but would have paid $168 for it plus tax. Also Honda might have not had the part in stock. Wait... So by looking at Amazon for cn250 starters, found one for $50 and a rebuild kit for $15. It is about saving money for me. So in someways Honda is no better at stocking parts.  |

I got 7600 miles on my Chinese 250. Still runs good. I had to replace tires about every 2000 to 3000 miles, but would have to do this on any brand. Roketa wanted to only sell a complete brake set ( a master cylinder, new caliper, pads, and line for $120 + $$20 shipping) but all I wanted was a master cylinder. So I bought a mc54 b master cylinder for left brake for $22 free shipping on Amazon. Had to do some miner adjustments since my 250cc scoot was a mc 13 250. It went through 4 starters. Been thinking of buying a kit for $15 so can have replacement starter ready. The worse part is waiting on parts, with Chinese scoots. It is reliable but having no dealerships is the sticky issue. A starter cost $50 and a kit cost $15. My scooter has been well maintained and is going on 8 years of riding. The 150cc air cooled engines are for short distance trips. So like maybe the longest trip would be 15 miles and give the scoot a break. The 250's can go for longer trips since water cooled. I rode my scooter 60 miles with ease. Rode from mid Missouri to Quincy IL.. me on my Bali 250 and my wife on a Honda Rebel. I would not try that on a 150cc china scoot, unless gave it a 15 minute cool down every 15 miles. But the same thing is required by Yamaha, Kymco, Honda... is air cooled scooters. You can't just ride many miles without engines overheating. My miles on 250 are mainly highway miles. A 150cc is not really meant for highway riding, just jumping on highways to meet up with other roads in a metropolitan area. The 250's are meant for long distance travel, from city to city travel. So let's say you live in San Jose CA. San Jose is joined together with other cities like Cambell, Santa Clara, Cupertino, Mountain View, ect. and this would be the perfect inviroment for a 150cc scooter. You have many cites that join one another like San Jose might stop with McDonald's on one corner and across the street be Santa Clara and Toco Bell across the street from McDonalds. But it is where one can get on his 150cc scoot and travel from one city to the next without having to worry about blowing a engine due to no where to pull off to give scooter a break. It has 35 MPH roads and also 55 MPH highways. So riding is more enjoyable knowing one can get around and do the speed limit. But the main issue, is Chinese parts and playing the wait game.

Has anyone ever had any troubles with the cam chain tensioner? Just wondering, because the type of tensioners on the 250's are the type with teeth and spring loaded. Apparently at a lot of high rpm riding, like at highway speeds, the teeth can break off, causing the cam chain to become loose. By the time a person figures out what is wrong, the chain is stretched out so far, that a person would have to rebuild the engine. The guy on YouTube explained cam chain tentioners and explain the type we have in Chinese 250cc scooter engines, are made for the common idiot, simple to use, but catistrophic when the tensioner fails.
On my CN250 engine, behind the rear tire and on the engine, sits the tensioner. It will come off by removing the exhaust, rear tire, and then tensioner. The tensioner has 2 bolts in it to connect to engine. The center bolt hold a spring in it. So basically the tensioner has a thing you push to get teeth part to go in to the tensioner. One would put gasket on to engine, then slide tensioner in while teeth part is retracted, than put two bolts on, than slide spring into tensioner which pushes against teeth part of tensioner and retracts it, then place screw into center of tesioner to hold spring into place.It cost only $16 for a new tensioner. Once the teeth part is in, due to the spring, it does not push back out. Only at high rpm riding, will the teeth eventually break off, allowing the cam chain to become loose.

It is not a squeeking of the belt. The belt can make a clicking noise, which some do, when they are new. See, the belt must be conformed to fit into variator. If groves are misaliegned the belt will make a clicking noise every once in a while until properly seded. If squeeking, something is wrong.
A new variator will squeek if the bar in middle is rubbing inner part of variator. I note, this is not a uncommon problem and should stop squeeking after 50 to 100 miles after getting seded.
A new clutch may loose power if clutch bell gets greasèy and causes the shoes to become glazed. Take off the bell and clean it and take sand paper to the shoes to get rid of glaze.
A grinding noise from CVT when slowing down, is a normal sound. It is the belt conforming to the clutch. It will make this noise until properly seded.
