I want to do some inspection, cleaning or replacing depending on the conditions. Kawasaki Victor 150cc.
The bike still has an issue where it starts to run shitty, and wale in mid rpms, loosing all power and sounding like it is getting starved of fuel. But it only happens when the engine gets hot, but it never over-heats. For the first 5 minutes, every time, it always drives great and is full of power as it getting warm. It just starts to have problems after 5-10 minutes of driving. I haven't been using it much recently, and still also need to go check if the piston for this model is supposed to have 2 rings or 3 rings. I was told if this is off it will result in a lose of power as it gets warmer, until it seizes. I got the piston changed 3 months ago and got a 2 ring piston put in to replace the 2 ring one that was already in it. I currently premix the fuel and have the autolube taken out. I do about 20-25ml to the liter of fuel. I use Benzyne 91 fuel.
Attached is a pic. On the far right you can see the fuel line going into the carb, and just to the left, the choke. Before I had this all taken apart including that black piece in between the carb and the engine, and it all looked spotless and clean so put it back together. I did notice that grey metal piece that the fuel line goes to (from the tank) and the choke is located on, could be taken apart into 2 or 3 pieces but didn't bother at the time.
So where is the fuel filter and the jets located here? Also, what is that big black box that says RIS on it stemming from beside the carb. Before I had it off but couldn't find any way to open it. It always seems moist with fuel or oil or something but can't figure out where it could be coming from.
Thanks for any insight.
