Engine has plenty of pinch, no airleaks that i'm aware of, slipper is tight, engine isnt overheating. Once warmed up its a wheelie monster,but after a couple of minutes wont even pop a small wheelie, tune doesnt seem to change. Running os8 plug, tried multiple different ones, but the issue persisted, honestly I'm stuck, never had such a problem. Only cause i could think of is an overheating clutch, clutchbell gets quite hot, but not hot enough to start overheating imo and clutchshoes have been ran only for like 5 tanks of fuel.

It still shifts trough both of the gears no problem, so i think the transmission isn't the problematic bit.

👍so it’s not shifting strait away ? It’s fine for couple mins then loses all its power kinda fing ? Is it just the wheelies or top speed as well ?

Fine for a couple of minutes and then starts not being as snappy on the low end, topspeed remains the same. I took the clutch apart and the housing was a bit glazed, so will clean it up and see what happens
