idle is okay - bit lean at 16-17 - need bigger idle jets 1/2 - 3/4 throttle perfect 13.8- 14:7 - you can feel car feels right - feels easy, power but very light throttle, feathering , seems boggy afr is around 11.5 , so going up hill 11.3 ish, so then i give it more throttle 50-70% throttle -afr shoots up even up hill up to 13.5 and feels like it is right again. is it supposed to be like that. all these readings are when everything is super warm. thats when i noticed it the most. using TPS load on megajolt
cbr600 carbs were set up by bogg brothers on my 1.4 afh setup. they ran rich because was using 150 jets. so at idle there ran 13 and at 2000rpm in stationory position AFR was around 13.0- to 14.0 but using the same carbs on my 1.6 afh conversion setup they run lean on idle idle was over 17 when engine cold causing exhaust to sometimes make like a spitting noise. when warm , gets around 15.9 -16.0 ish in stationary position revving it up to 2000rpm gets it where it should be 14.7, (when engine is warm) i've done some research and timing shouldn't affect AFR significantly to get dodgy AFR readings. theres a idle screw that controls where idle position is.. i increased that to around 1500 rpm to get a decent enough AFR to avoid damage. i took off the brake vacumm hose and re-installed it to make sure it's dead tight. where else can there be air leak. the jubilee clips around the intake manifold for holding the carbs are pretty crap. they are tight but if you overtighten these jubille clips the nut jumps , making you tighten it to a certain limit. but noticed tihs issue with old set up. the only thing that is different apart from the engine lol, is that im doing the testing with no bonnet and no induction pipe and ram air filter
