Uh, I can't read...
But on the bright side, I have a few friends in area so I will actually see you sometime and pick up a few. I want a few extra tires because the bike shops around here charge a fortune and I got rooked into buying a tire that doesn't fit because I had a blowout.
But thanks for responding, even though I can't read.

Will do and check this out before taking it to the shop. Can I run the bike without the exhaust pipe on just to test and see if there is a restriction in it? Already feel like I messed it up enough without doing it more. (Hear this a lot from the wife atm)

Haven't got to check most of the stuff Alley suggested, but the carb is fine and adjusted correctly. Gas is not a problem because the bike feeds gas correctly and nothing is stopping the flow. The shop I got the scooter from is going to call the importer tomorrow, but he thinks it may be a slipping clutch/transmission. He will work on it for free for me, but I have to get it 25 miles from here to his shop. It may not happen for a week or two the way things are going, but I will update what I find out from the shop.

OK. Officially checked the tires today by tested another tire the right size and testing my tire on another bike. My tire on another bike worked fine. No decrease in speed either getting there or maximum speed. The other tire, 103/60-13 which is what it should have, made no difference. My bike still will not exceed the 4200 rpm or 45 mph mark. Actually with the correct tire, my bike would not break 35 mph. Nothing has been touched on the carb, so anyone got any ideas?

I had almost the same thing with the same mileage happen to my DF300TKB. It's motor is the Linhai 300cc. I wish I could say I came up with the solution, but one of the High School kids that I work on their laptops did.  He works on outboard motors, but had a better idea than me. He pulled the air line off the carb and it was blowing back gas into the air filter. This is what the carb looks like on mine, hope yours is similar.  The are just 2 screws to take the top (brass piece) off the carb. Be careful of the spring and don't lose it. There is a rubber diaphragm in there that has a metal pin on the bottom center. It is supposed to be concaved downward, but mine was stuck up, convex.  You can see the diaphragm on the left picture, it is the part under #2. Put this back together aligned up with the rubber seal, and mine at least, worked like a dream afterwards. Hope this helps some. |

Yeah, I am kind of angry that they told me the wrong tire would fit. Haven't had time to go chew them out yet because they are exactly opposite of the direction I head for work. Had no choice other than that to get home though.  And that was the exact tire I was looking at ordering. |

Could you post a picture of your scooter or message me one?
Thanks

I have a DF300TKB. If you look at the specs on the bike, it says 55+mph, and I regularly cruise a 60-65 on the way to work. .sunnymotor.com/product_info.php?cPath=28&products_id=134#descr" rel="nofollow" target="_blank"> .sunnymotor.com/product_info.php?cPath=28&products_id=134#descr I recently changed the back tire from a 130/60-13 to a 130/70-13 because I was told it would fit. (Also I had a rear tire blowout and this was the only tire they had, so maybe that is why they said it would fit.) Anyway, it barely goes on, and when the bike reached 50 mph, the tire rubs the rear of the engine case and the bike kicks in the governor after a few minutes of this, stalls and then starts running normally. Ok, I just changed where I rode and adjusted to the slower speed. Then, I checked and changed the factory spark plug which looked like it had been through 50000 miles and not 2200. I set the gap, installed the spark plug, and on the jack everything ran normal. Could max rpms if I wanted and ran good. I set it down, went for a test run, and the bike would not exceed 45 mph or 4200 rpm. No what, on the ground the bike won't do it. On the jack, it runs just fine. The only other thing I have done is refill the tank, but I have never had issues with this Shell station before. (I use it on the bike and all 3 cars.) Also the bike does not overheat, just won't exceed 4200 rpm. So I am wondering if the cheap shocks on the back of the bike, which are not adjustable, have settled some and the rubbing on the tire is capable of reducing the rpms enough that it will not exceed 45mph? If so, does anyone know of a shock spring stiffener I can place on the coil springs to make the bike not lay back so much due to the shocks? Thanks in advance for the help. |

My name is Matthew, and I just joined the forum Monday because I recently purchased my first motor bike of any sort. I purchased a new DF300TKB. Sunny is the US company I think. Anyway, I drive 100 miles round trip to my job 3 days and 150 miles 2 days here in South-west Missouri. I am 47 and had to buy a trike because I have balance issues from a stroke, but got the tadpole version because I wanted to be able to lean. Attached is a picture of what my bike looks like, color and all.  |

I have a DF300TKB that has this exact motor. To make mine not come off, I noticed that there were notches on the air cleaner end of the hose and one of them was in the wrong spot. Also, the hose was a little long so it didn't want to stay on the carb. I trimmed the long end about a 1/4" and made the correct notch on the air cleaner side. Not looking at yours, you may need to see if your hose is too long, and which end would be best to trim. The other bike at the shop had the hose with the right length, but no notches. Hope that helps.
