I took your advice and put in 12 gram sliders. It has improved by lowering engine rpms and raising the top speed. However it still goes up to 8000 rpms at 50 mph rather than 45. I am interested in what you did to change the rear gear ratio and lower the rpms. I am not interested in racing, just cruising at 45mph at lower rpms.

The carb is doing fine now. I was able to get ahold of a used DENI carb. I rebuilt it and it now performs flawlessly on the trike. I test drove the trike tonight. It actually runs very well for just 300 miles on it.

Looking forward to your thoughts.

Hello all,
I purchased a used PST150-H on Saturday. It was from a dealer that is liquidating his inventory. The starter was not working so I pulled some the seat and some body parts to work on top the engine. I kept smelling old stale gas. With a flashlight I could see that the fuel tank was leaking st the fuel sensor. I pulled some more body parts to get at the sensor to check the gasket. Upon pulling the sensor I found that the float split in two and came off the lever arm. After removing the tank (no small chore) and then spending more than an hour fishing the old float out I reinstalled the tank. I put and old carb float on the end of the arm, reinstalled the sensor and refilled the tank. After letting it sit overnight it leaked again. This time was able to see the that the leak was coming through the sensor alongside the three wires. I am getting a new sensor to end this headache.
This trike only has 300 miles on it but it has been sitting for a long time with a full tank of gas that turned yellow and stinky. The carb was gummed up also. I haven't ridden it yet but I am sure having fun taking it apart piece by piece.
BTW, I plan to only use unleaded premium with no ethanol.
