I'll start with the 2 questions as I don't want to tell some story and lose you before you get to them.

1. If I have a Kawa Victor 150 with an autolube system and I'm going to mix 2T into the gas tank as well, is there anything I need to take out of the bike for the 2T to reach the piston chambre?? My thought was maybe there was some sort of way the 2T would get filtered out if I mixed it in the gastank itself, if it is set up to have autolube. Maybe the fuel filter, and I don't want 2T pilling up somewhere. I believe I should be able to premix it in the gastank and have it work fine but thought I should doublecheck as one time I mxed it in the gastank while using autolube too and I didn't much smoke at all after driving for 5 minutes.

2. When you give it full throttle and it hits the powerband on a 2stroke, then makes that sound like its dying and looses all power before getting through the powerband (without the engine shutting off, can just release throttle and drive on), could a reason be that it isn't getting enough 2T lubrication in the piston? I now have everything complete clean on guck on the inside and just replaced the piston. Could it be from a cold engine?

Now my story. I got the Victor and made a previous thread about what to do clean it up. At first it didn't have great power and sometimes would seem liek it lost all power. I then replaced the end piece(the silver peice) on the exhaust and got the rest of the exhuast (the normaly black piece) cut open and had all the shit burnt out. Then it drove like new but still felt liek it was lacking. I took the carb and airbox off and it was like spotless. So it felt like the bike was pretty much like new anyways and it always hit the powerband fairly smoothly unless driving for a while it seemed liek it would lose some grunt.
Then today I was driving very fast like 150 or so and really opening the throttle and the engine lost power and shut off at high speed. I pulled in the clutch, stopped and tried the kick start and it had liek no resistance. Opened it up with a mech and the piston head was fuc_ked. Those two little rings at the top that are normally moveable and like springs were like melted into the piston head on one side and immobalized and the piston head was sracthed up.
This could be because it was too hot or because there wasn't enough 2T and I was putting it up in high rpms for too long. Still not sure though. So I got the "lid" and piston chamber peice or engine head or whatever shaved down to make it nice and smooth again, the mech got new gaskets and o-rings and new piston head, put it back together very nicely with solutions on the bolts and orings and everything. (I watched him the whole time and helped him as well.) Also changed the spark plug as it was completely wrecked. Now it drives even better then before but just today I put it up in the power band again and it did the "engine dieing thing" where it looses power and doesnt stall, and then I drove on, I tried one more time and then it went right through the powerband fine like usual..... I'm not sure whats up because now everything is perfectly clean inside and has no more guck clogging stuff up. It seems to drive liek new but I'm just worried about this one time it made the shitty noise in the powerband.
