ok so first shake down run. love how it handles and steers and stops..
now its runing rich. stinking rich. standard mains and pilots right back to one turn out.. on the throttle it picks up really fast and runs great but hunts a lot andis jerky on a steady throttle. but the main rub.
gets to 5.5k and splutters and wont rev past it .
way to rich to even run? or timing out 180? and how easy is it to check timing...everything lined up perfect after the mcct fitted.
cams and springy things iv no fecking idea and wouldnt go near them with a barge pole ..... its almost like im hitting a limiter its that sharp of a stop..
im trying to find the guide on 180 checking to rule that out but cant find it . checking it mite be one thing but if i have to change anything i mite be needing a second set of eyes ..
Except it wont help with 180 degree out if that is the case. It's easy to rule out the 180 out but the only issue with it is that it requires rear cam removal which could possibly upset you valve clearances depending on how exact you put the cam's back ie how much you tighten them back on which has a small affect on clearance, so do check these.
I'd be tempted to check the carbs first. Choke sticking, are the emulation tubes the right way around. What needles are you running and what other settings ie jet sizes and where is your mixture at. What air filter have got. Temporally remove the air filter and see if that has an affect which would suggest fuelling rather than timing if it gets you past the 5.5k. Note 5.5k is where the 180 out kicks in when ridden and also note it will go past this blipping the throttle at a standstill so has to be ridden to test. It's also possible to jet carbs to mask over a 180 issue and get past the 5.5k point as was the case with one of AP's bikes and he rode around like that for a few years without even realising. It was only after many attempts of me trying to get his tuning (jetting) right and many carb removals with no luck that we finally resorted to checking the timing and discovered a different animal after flipping the cams.

If it's 180' out you'll hear it as it'll sound different (very deep) .
they do sound different..its looking like its the 180. just confusses me as everything lines up. its how to find out.iv read the posts here in this thread and it makes no more sense to me .
Set the rear cylinder to tdc check cams are correct .at ri&re . Rotate crank 1&1/4 turns anti-clockwise till front tdc check cams .are at fi&fe .Simples

right and that tells me if its 180 if things dont line up? ..god why can all bikes not be 2strokes lol
