Does anyone have a tuning spec chart for the Apex gt ?I am noticing that the cam angle is set at 3:3 for the RX10rtl- rtrl- gtl at 0to 2500 feet level.
But on my GT it was at 6:1 for the same altitude. :itchy:
What is the correct twist angle?
 

Hi dyama i took my secondary apart yesterday and it was in 3+3 60 degrees w/white spring,and the weights look preety much like the stock ones in my 03 except they have 3 rivet holes,w/heavy 17 grm. rivets and on my grm. scales weigh 82 grms. WOW what a cam arm weight,i have never seen a stock weight this large or heavy!!! Oh ya my belt was a little slack i will take care of that today and check my offset,center distance,and belt deflection. ;)!Oh ya no excessive greaze on shaft..Sorry forgot to mention this is the attak,but i think all apex are same clutching..
 
Hello everybody! I am still not sure what is the stock setting on a shorty for the driven cam????
Is it 3:3 60 degree or 6:1 70 degree twist angle?
Remember it is a 121 inches track !
 
The attack is the white spring wrapped at 60.
All the short tracks,GT,ER,RTX use the pink spring wrapped at 70.Hope this helps.
