VHM ADJUSTABLE POWERJET FLOAT BOWL |
|
| The VHM PowerJet Carburettor Float Bowl has been designed with an adjustable PowerJet needle. | £255.00 + VAT |
| The PowerJet can be adjusted from approximately #0 up to #80 PowerJet sizes by simply adjusting the external screw. | |
| 1 turn of needle is equal to #40 PowerJet and 1 ¼ turns is equal to #45 PowerJet. | |
| No need to remove the float bowl to make adjustments or change the PowerJets. | |
| The standard PowerJet is not central in the carb float bowl. | |
| Because of this, through long fast corners the standard PowerJet can draw air when the bike is leaned over and at fully open throttle, | |
| as the standard PowerJet becomes higher than the fuel level in the standard float bowl. | |
| This can cause detonation, as the PowerJet draws in air rather than fuel. | |
| The VHM Float Bowl takes fuel from the centre of the float bowl. | |
| The VHM Float Bowl has 2 channels, taking fuel from the centre of the bowl and then from the adjustable PowerJet screw needle. | |
| This eliminates the possibility of the PowerJet drawing in air and eliminates detonation caused in long corners with the standard PowerJet system. | |
