Heres a pic at bdc and tdc i did some porting of thr exhaust beacuse with the mini stroke i goes up a mm higher but also a mm lower so i not only wanted to male it rev higher by increasing exhaust at top but had to open up bottom to match tue piston , still dont know if the piston is hogh enough at tdc but we will see.m.

Looks like you have the wrong piston or a too short rod.

Looks like you have the wrong piston or a too short rod. Indeed its wrong piston its off a athena sport which i have used on an athena evo before i know that pistons are best matched with their kit but the stroke is already not stock usualy have to put about 2mm of spacers to make it work but not with this piston and bore just throwing things together out of leftovers onthis one atm.

what do you guys think this adjustment 9n the power jet is supp9sed to do ***exactly?*** i have had a few carbs wwith power jets but they simply had a sscrew on the top just so you could open and change the size of the pwr jet. in this instance the fuel travels down a brass atomizer i guess that desends half way down the mouth of the carb while all others atomized at the very top of the mouth and this "mixture screw" does open up quite a fre turns. do you suppose the more that it is opened the more fuel is getting dumped or rather opening up the nozel actualy adds air to the power jet circuit ? im pretty positivr that you can still blow a small amount of air through it when fully turned to closed.

I think 90GTVert did quite some tuning with a power jet. You might wanna read through his thread and find out about his findings.

I've only used the Lectron, but turning the power jet adjustment out/counterclockwise richens and turning it in/counter-clockwise leans the power jet circuit. In the case of the Lectron, it's a fairly sensitive adjustment so they tell you not to go far with each adjustment (1/8 - 1/4 turn).

OK so I had thought I had the weights all sorted out Don't know fit CVT or carburetor related but the bike About halfway through acceleration I'm sorry to think that its cvt related as I am using a completely stock clutch Paired with a molosi over range variated I'm thinking maybe the stock clutch just gets hot right out the gate because it seems to work all right before it warms up but that was having me think it may be rich however when I try to lean it out it acts worse

If your issue is halfway through acceleration, it shouldn't be the clutch. If a clutch has issues, it is usually noticed during the initial period of takeoff. Maybe the first few seconds.
Getting hot over time and changing could be the clutch or clutch springs. I've also had contra springs fade from heat and noticeably change RPM once hot. With the 2T and a setup that really has to be on the pipe in a specific range to work, if something in the CVT causes RPM to change enough over time, it could move it out of the powerband enough that it struggles. For me, that usually makes them feel similar to a rich condition where excess fuel can make it tough to hit the pipe.

well What I thought was CVT or possibly carb issues Turns out I probably have a full bottom up rebuild now. After changing the wait seeing as I was noticing it would bog at 10800 And then pick up again to about 10200 I figured that might be the Rollersbeing to light When I switched him out I noticed however that there is about one mmeter of horizontal play on the variator side output shaft of the crank. Does this mean that the cranks arm came loose from the bearing or that the bearing probably came loose from the case? Either way I am guessing it's gonna need new bearings after being split open and new seals at the very least damn I thought I was close to being done with this one.

OK so besides the problem that I recently discovered I was still trying to play around with swift swapping out the carb Because it was a knockoff pwk with literally a plastic bowl I want to see how it would run on the 19 mmeter dell. So I put in the biggest jet I had For that size which was A102 main jet It came with a 75 install Start it up and unlike with my air code cylinder I had brand this carbon although only on a bench not on the road it seemed to do fine but this Configuration seemed to not like anything past a quarter throttle I change from a 92 down from A102 and then just to see tried in 82 All the same exact results pretty much Is there some thing I missing do I have to switch out the atomizer on this card or else it's no good for 2 stroke It seemed to Act good on a engine I had sitting on a bench which was 75 CC's I can't see how How it would have needed something bigger than a 1 or 2 when I was using A120 to 124 on a 28 mmeter card going down by 9 mmeters should somewhat equate to about 9 with jet sizes at least right Somebody please tell me what I am missing have never mess with these dellorto's before

I think I found the problem exhaust is closed and leaking Bike will not die if put rag on end of pipe But will die if I put hand over carb it also obviously as before will die if I put it past quarter throttle.
Obviously need to remove exhaust and probably get a new one would be the next move anyways so time to work on my pippy🐷🐖pigg.
