I have a Roketa Sicily 150 with 300 miles on the odometer. When I first purchased it, it owuld easily top out between 55-59 mph and 52 during HUMID weather conditions. Now at 300 miles it wont run over 39-40 mph. I had a certified motorcycle mechanic look it over and he said it has to be the belt. Who manufactures the best quality belt for this engine? Also will the aluminum intake manifold adapt to the stock carburetor. What brand of performance air filter can be fitted with the least amount of modification. What size carb jet would be the most beneficial to increase performance w/o any internal engine modifications. Once I replace the belt and get it to perform normal as it once did, I'll then make a decision on the performance-increasing mods to moderately increase its performance. Please help!!!!

Also for durability, can the aftermarket aluminum intake bolt directly onto the stock carb

I don't think it's the belt. Last thing you need to do is start frantically replacing parts, sooner or later you may fix the problem, but why not figure out what it is? First thing to do is look for loose stuff, like the carb loose in the manifold, throttle cable nuts loose, etc. Make sure the fuel filter isn't plugged and the tank vent isn't blocked. When it tops out at 40 mph does the engine sound like it is running faster? Maybe the variator isn't shifting. Check the carb diaphragm for pinholes or cracks. It may be a lot of work but you can find the problem.

I agree with Swampsniper. Does your certified motorcycle mechanic know anything about CVT transmissions?
With only 300 miles on it, I would start with the carburetor, fuel supply, and intake manifold. They are more likely the problem and are easier to fix.

THANKS BOB AND JON...THE CARB WAS LOOSE ON BOTH SIDES OF THE MANIFOLD, WE REPLACED THE CLAMPS AND TIGHTENED IT, IT STARTED QUICKER AND SOUNDED BETTER BUT STILL WONT TOP OUT OVER 39-40MPH AND THE ENGINE SOUNDS PERFECTLY NORMAL JUST AS IT ALWAYS DID. I REPLACED THE FUEL FILTER, STILL NO CHANGE. THE THROTTLE CABLE IS TIGHTLY FASTENED. ALSO ITS NOT AS SNAPPY IN THE BOTTOM END AS IT ONCE WAS, IT TAKES A BIT LONGER JUST FOR IT TO GET UP TO 35-40...I REALIZE THAT OUR SEVERE LOUISIANA HUMIDITY CAN REDUCE TOP END AND PERFORMANCE TO A CERTAIN DEGREE BUT BY 17-20MPH, NO WAY!!!!

ONCE MORE WOULD IT BE FEASIBLE TO REPLACE THE RUBBER INTAKE WITH THE ALUMINUM FOR DURABILITY AND LONGEVITY PURPOSES. IF SO WILL ONE ADAPT TO THE STOCK CARB.

Not until you get the scooter running right. The loss of top end is starting to look like a Roketa thing. Do you know anyone that can hook up a timing light and check the spark advance?

sicily150, you don't need to use all capital letters. in forum ettiquite that mean you are yelling or shouting.
I had two things happen on my scoot. One, the ignition coil started to go bad, the engine would start and run just fine, but it couldn't go over a certain speed, in my case about 6,000 rpm. Second, the OEM belt had worn down a little and stretched, only about 3 hundredths of a inch thinner and it grew about 3/8 to 1/2 of a inch longer, but that was enough to take about 5 to 10mph off the top end. Third, the OEM rubber intake manifold had started to deteriorate and crack leaking air causing it to run too lean at WOT. So you probably have these same issues that i ran across. it is not the carb, unless you dinked around with it already. Some people have problems installing the longer racing manifold, with the carb in place, the carb may not clear any frame members or something on the scoot. So one pretty much has to try it and see if it fits.

Sicily150; For most of the Chinese 150 scoots, you are asking for too much to get a consistent 60-62 mph. Most have found it best to not start modifying these scoots unless you have a good bit of background that way. You are just asking for more problems. If you need a consistent 60-65 mph, you should be on a 250. That will give you more reliability and durability with higher speed cruising, usually a better ride at speed as well as safer handling.

Sicily150 for a Gy6 150cc to go 60-62 mph means it has to turn over 10,000 rpm to do it. The engine life is shortened a lot at that performance level.
Now you can put in a big bore kit, and a stroker crank and a hot cam, along with a bigger carb, uni-filter and a high-perf exhaust. Then you need a racing variator and a racing clutch too. finally you need to change the transmission gear ratio so it turns less RPM at WOT. Now you can go 60mph, but the scooter body and frames and tires aren't designed for that speed, it'll be a squirrely feeling ride at those speeds.
So now you are spending a lot of money on this, and your reliability will be less too. Engines turning 10,000 plus RPM's are commonly seen in racing and they rebuild those engines a lot. If you want to go 60mph you need at least 250cc sized scooter. If you are going to be going 60mph plus for long periods of time you need no less than a 400cc scooter.

Yeah. Me too! I'm impressed when women tinker with bikes like this- and she's really broken it down pretty far!

Any one try to send an email? Yes, I talked to her by email yesterday. Atlanta has been so hot that she hasn't been able to work on the scooter (she doesn't have an enclosed place to work on it). And she has had a few "life issues" that have taken up a lot of her free time. She's out of town at a wedding this weekend but said she will check back in here next week and hopes to be able to get back to fixing the scooter soon now that the weather is settling down there. Jon

I'm going to jump in here because I suspect Jen has her hands full with her scooter and other issues.
She took the scooter to a local scooter shop and they told her it needs a "top end rebuild" for about $600-700. Since it broke less than 6 months after she got it and it had a 6 months warranty, she also contacted the dealer. They seem quite willing to help but they want more information about the problem. I pointed out to her that they could buy her an entire new engine for under $200 and that might be the simplest solution, and she mentioned that to them.
She is currently talking with the dealer and the scooter shop. Her concern is that just getting a full diagnosis from the scooter shop will cost her $200 and she's a little reluctant to throw that money at the problem unless she has some assurance that it will lead to an economical fix. I suggested she ask the scooter shop to apply the $200 to the repair (they have to take it apart to diagnose it and they have to take it apart to fix it, so it should be the same process and the same $200).
That's what I know so far -- don't know if she's taken it further or not. I understand her reluctance to spend several hundred dollars on something she just bought just to get it to work. That's the chance we all take with a parts-only warranty, but if it breaks then we have to decide if we want to spend the time or money to fix it. If I hear more I'll post it here.
Jon

I would have been there a long time ago to tear it down for her when this all started, but I'm no where near her. I don't think any one else on this board is either. That's the problem. I think she is at the mercy of the shop.

That's a shame. I had a similar problem with my Roketa, dropped a valve seat inside the head, exact same symptoms. But, I was able to buy a Complete New Head for $65.00. Makes ya sick to know a "shop" is ripping her off that bad. I've seen new whole engines on E-bay for about $350.

Hey guys! Sorry I sort of vanished there. As Jon said, first it was travel, then the heat, then some minor health issues, and then I found out that I either need a top end rebuild or a new engine. In Atlanta there is an independent scooter seller named Scooter Steve www.scooter-steve.com/He wouldn't even take on the rebuild because he's had so much trouble with getting parts but he said he'd put in a new engine if I could get one. ATL Scooters is a dealership. www.atlscooters.com/They said they'd do the rebuild but they charge a LOT - $85 hour in labor. And they really seem like your typical car dealer types. So, right now I wait for Scooter Steve to get back from a trip out of the country. Then he's going to work up an estimate of repair for me to send to Free-Ride Scooters, who I bought Carpi from. Free-Ride is very aware of this website and I told them it shows that I had the problem within the warranty period (6 months parts). So...we'll see. This just ended up being something I couldn't fix though I wish I could. OK, I'm going to be off for a little while, but I will come back with an update when I have one. Oh, and it's fine if the thread got sidetracked by others' problems. Thanks, everyone, for all your help and well wishes and "atta girls"! Jen
