It seems the scooter responds positively to leaning out the jetting. The 110 main jet though seemed maybe it might be going too lean up high. Increase main jet to 115 decrease atomiser to BE3 now understanding that is leaner, air fuel 2 full turns. This is test 11 still on the P200 drilled air filter.
On the stand changing air fuel 3 - 1 it seems to enjoy 2 turns most.
Sill does not rev out on stand choking makes slightly worse. Ran OK but something(s) not right.
Wanting more jets and cable I head to scooter speed. They do not have the 140 air corrector. That will have to wait but may run a test with 160 to check the impact. I pick up a 45-140 pilot, BE2 atomiser and 112 main jet.
We have the DRT Spacer now and it allows the T5 air filter to fit comfortably under the Pinasco air box cover. Beginning with Test 12 I plan to move forward testing with the T5 air filter which is not fully vented.
For Test 13 main jet will be 112, atomiser BE2, pilot 45-140, air fuel 2 turns and T5 air filter. This did not fully rev out on the stand but is reaching higher rpm. I think I like the 55-160 pilot though the idle speed was lower. I will run this on the tires tomorrow.
Should we be concerned the jetting seems to be going light?
