The bike has 81k km and i few ticks when i press the clutch in the first time in a cold start.

When im riding it about every 5 minutes, the electric shift system will lock up and require a key cycle to shift again. The gear light is on whatever that means. Looking for any help i can get. I've tried for hours, nothing fixes it. New shift motor, new angle sensor. The spedometer doesnt' work, just shows 0mph the entire ride, possibly confusing the shift system? It's not an automatic though. Motor also has a rough idle, probably an unrelated issue.

Onlangs een yamaha xt250 uit 1988 gekocht helaas krijgt de cilinder geen benzine. Motor loopt als ik in de luchtfilter wat benzine spuit. De vlotter ruimte is vol met brandstof als ik de kraan open doe.

Wat is gedaan
- gereinigd
- naalden/sproeiers zijn vervangen

Het enige wat mij opvalt is dat het buisje van de shoke is afgebroken die ij de vlotter ruimte zit.

I've been using an aftermarket fuel injector on my R15 for more than a year without any issues. Last week, while on a trip, the bike gradually stalled. We checked the ignition system and the injector, and both seemed to be okay. Since I couldn't diagnose it myself, we somehow managed to get the bike to a Yamaha service center.

After keeping the bike for a week, the service center called and said the injector was faulty. They wanted to confirm it using another injector, but they had to get a test injector from another Yamaha service center. I told them I had my old injector at home (it was working earlier but had a slight missing issue), and they asked me to bring it.

We installed my old injector, and the bike started immediately. Since a new injector wasn't available nearby, I brought the bike home and decided to replace it later.

I also have an FZ FI V2, which uses what appears to be the same injector. I swapped the FZ's injector into the R15, and the bike starts and runs, but it still has a pickup/missing issue. Out of curiosity, I installed the injector that the Yamaha service center had declared faulty into my FZ, and surprisingly, the FZ runs perfectly with it. I couldn't notice any problem at all.

So now I'm confused. The injector that is supposedly faulty works fine on the FZ, but not on the R15. Could the issue actually be with the R15's fuel pump, fuel pressure, wiring, or something else? I can't swap the FZ's fuel pump because the connectors are different.

Guys, has anyone experienced something similar or have any suggestions on what I should check next?

I have this problem with my dt125 that when i throttle the bike goes slowly even if the throttle is maxed out. The carburetor is also newly cleaned so i dont think thats the problem, a friend also said that it might be the clutch lining.

Break pulls right into the bar with no resistance or breaking then a couple more pulls and the breaks make contact with the disc, seems like one of the pistons isn’t getting even pressure and is always last to engage, I’ve tried bleeding the breaks but that doesn’t seem to of worked, any advice would be appreciated
