@HOTSHOT-III Hopefully the issue gets resolved as I don't want to lose the data they're hosting. The important stuff I ought to host here to guarantee it isn't lost.

Hi everyone, my name is Mattia, I’m 17 years old and I’m from Italy. I recently got a Yamaha DT 125 RE and I’m really excited to share my passion for motorcycles. Since I don’t have much experience yet, I’m looking forward to learning from you and getting your advice to improve both myself and my bike. At the same time, I hope I can help others by sharing solutions to problems I’ve already encountered with my DT 125. I’m really happy to be part of this community and can’t wait to learn and contribute!

@ChuckSR86 Do you have a DTR or a DTX? [image: yamaha%20dtx%202006.jpg] or [image: yamaha%20DT%20125%20R%201991.jpg] I must admit, if it's light greenlaning, then you can get away with it on supermoto in the summer? Anything more hardcore then some knobbley's would be ideal. For simplicity, I'd be lacing a set of hubs with ally rims for knobbleys. That way you only need to swap the wheels and not the brakes.

Hello everyone, I’m new to this forum, I’m from Italy and I own a Yamaha DT 125 RE. I need some help because I feel that my bike is not performing as it should. The bike is fully derestricted: it has the ground wire connected, a full Giannelli exhaust, and I also blocked the small bottle near the air filter (not the one on the intake manifold). After doing this, it seemed to give slightly better performance. Regarding the carburetor, the idle is a bit unstable: sometimes it’s lower, sometimes higher. The air screw is almost completely closed, even though the air filter is completely stock and unmodified. I’m not sure if this could be related to the performance issues. Another thing I noticed is that the YPVS valve is not aligned with the exhaust port. It is actually “reversed”, meaning it stays more open than the fully open position. When the valve is correctly aligned with the exhaust port, the bike becomes very slow, especially in acceleration (I don’t know why). With the valve set as it is now, the bike reaches about 122–123 km/h (around 77 mph). For reference, the engine has been fully rebuilt and has about 5,000 km on it. Even so, when I compare my DT 125 with others I’ve seen on YouTube, mine seems slower, especially in acceleration. Do you think there is something wrong with my bike, or is there anything else I can do to make it more powerful without spending too much money? Thanks to anyone who can help.
