Cheetah tuning issues


Recommended Posts

damn dude  sounds like you have a jacked up motor.. 

 

it may be way to rich on the pj  OR the pj is plugged inside the bowl.  

 

the 927 will stick a valve in less than one days ride.   you maybe able to push them up just fine  but when the motor is running they wont work.   try the blocks first  IF the motor revs then you know yo have a problem in the pv pressure up side. 

 

check he supply hole in the base  make positivley sure it is clear.  and there is a gasket in between the top plate, and middle section  and gasket inbetween the pv base  and the cylinder right?   the pv has to see exhaust pressure or it will never open up.

if i rember right  its a plastic seal on that lil piston?   look at the base and you will see the lil supply holes  make sure they are not plugged or have crustys in there from carbon build up.


 


927 will not work on a pv motor.  but  if it was all fresh  it should have ran.  at least the 1st day.


 


when you say your not grounding the stator?  is the grond there on the back of the plate?  and then a black wire coming off the stator to the main harness??  you need to ground the stator.  


check plug boot resistance  make sure it is around 5k ohms or less.  pull the plugs and kick the motor around  it should have a nice bright BLUE spark.  any orange or yellow and the coil is weak or the boots are shit.  on alky run the plugs with .18 tho plug gap  any more and it can cause misfire at higher rpms.


 


 


figured i'd post my responses to your pms here also.  guess i'm one of the only ones who has gotten these motors figured out??

It's not the power valves, put the block off plates in and same shit!!

It's not the ground wire to the stator, hooked it up and same shit!

Not the high flow fuel filters, as I took them off and ran lines direct from pingle to each carb.

Something is wrong with this thing and its killing me.

Almost time to send it to somebody!!

Well boys I finally got this thing to run semi good. Still needs fine tuning, but holy shit!! Going from a aggressive trail port stock stroke motor to this 535 cheetah on alky is every I thought it would be and more!!! Wow you really do need to hold on when that switch turns on!!! I'm 145lbs soaked, and wah! Can't wait to tune this bitch in!

Anyway I kept tuning like lectron instruction say, get a nice idle, smooth and crisp throttle response, and then go ride and tune power jet. So the motor was always lean. Now I have a ritch shitty idle, but not to bad when on the move.

When I was adjusting them I was only making sure they were the same I didn't actually look at the #. When I get a chance I can pull em and check if you want.

But I might need to adjust a bit one way or the other, but I am within a 1/4 turn now I figure.

I need to get it out somewhere, to really run it
