Went to replace my belt today after yesterday's ride resulted in some late ride shuddering, and what I thought was a possible clutch problem due to the bike not wanting to behave at stop lights, it just wanted to keep going. I just checked that belt last weekend and it looked fine, but not now. Glad it didnt break on me and I got home, running a few red lights and stop signs.....
Clutch looks good, no loose material or parts, shoes look ok, but the belt is missing about 7-10 teeth.
Thought I had 2 belts in reserve but when I went to install it there was a problem with the belt seating into the pulleys and had the hardest time getting variator plate back on. Then I remembered that these two belts came from a chinese supplier and like most stuff from there, not quite up to specs.
I believe the DT 300i requires a 24mm width but the ones from Hornet were 25mm.....makes all the difference, and when I went to ebay today to find a replacement, many are selling those replacement belts with the same 25mm widths....and claim its the right one! Have tried locating and sizing a Dayton and Gates brand but no cigar. Kymco OEM are almost double the price of generic but worth it if you cannot use the generic.
BEWARE! 25mm will not work! Wish we had a better supplier here in the states but we don't, Kymco USA is terrible about replacement parts. Fortunately I've become good friends with a supplier in Taiwan and though shipping takes a bit longer, I give him my part number, he gets me my part!
