Hi Jeffdeq,
Your links I cannot see them:
You can use PUSHAPICTURE, most of us use PHOTOBUCKET it is free and you can create an album keep your pictures there and they have an editor if you want to say something in the picture.
photobucket.com/This one you do not have to join just click on upload another picture and find your picture on your computer. What I do I first put the picture on my destop and copy it from there.
picturepush.com/host.php?image=10075950Click on upload find your picture then go to the the 2nd URL that where it says CLICKABLE PICTURES Click on the URL for forums 1 and it will turn BLUE then RIGHT CLICK and CLICK COPY and then come here and Just PASTE it.
with 10 gram rollers that sucker should be cranking out at least 8000 rpms. So something is not right, and it may just be the carb needs to be adjusted it may be running to rich.
When I bought my PST150H trike back in 2009 it came with 10gram rollers and it would crank out at Wide Open Throttle at over 8000 rpms. I did not like that the motor was screaming at 8000 rpms so I started to put in heavier weights. I am currently running 12 gram Dr. Pulley Sliders.
So with 10gram rollers the RPMS should be well over 7000rpms.
First Check your Air FIlter and clean it and put it back on.
Then adjust the Carb here is how to do that:
Alleyoop
Here is what your Carb area should ressemble. NOTICE WHERE the Fuel Ratio Mixture screw is RIGHT UNDER THE 1/2" GOLD CAP. You need a Small flat head screwdriver and get your hand in there to adjust it.
ADJUSTING YOUR FUEL RATIO MIXTURE:
YOU WANT THE HIGHEST RPMS OUT OF THE AIR RATIO MIXTURE SCREW:
Start your scoot and Get The Engine Nice and Hot about 5 minutes so that the Enricher IF it has one is no longer Allowing Extra Fuel to come in. Then do the following to fine tune the Fuel Ratio Mixture:
FUEL RATIO SCREW:
FIRST TRY RICHENNG THE FUEL MIXTURE FROM ITS CURRENT SETTING:
RICHEN THE FUEL RATIO MIXTURE:
1. Turn the Fuel Mixture Screw COUNTER CLOCKWISE 1/4 of a turn and wait 10 seconds to let the engine catch up with the new setting.
a. If the RPMS go up REPEAT #1 UNTIL the RPMS GO DOWN OR NO CHANGE(then go to b).
b. TURN the Fuel Ratio Mixture Screw CLOCKWISE 1/8 and that should be your highest Fuel Ratio Mixture setting—GO TO #3.
******If on the FIRST 1/4 TURN from the STARTING Position IN #1 ABOVE the RPMS GO DOWN OR NO CHANGE , turn the Fuel Ratio Mixture Screw Back the 1/4 turn to the Starting position and wait 10 seconds until the engine catches up -- GO TO #2 ******
LEAN THE FUEL RATIO MIXTURE:
2. Turn the Fuel Mixture Screw CLOCKWISE 1/4 of a turn and wait 10 seconds to let the engine catch up with the new setting.
a. If the RPMS go up REPEAT #2 UNTIL the RPMS GO DOWN OR NO CHANGE(then go to b).
b. TURN the Fuel Mixture Screw COUNTER CLOCKWISE 1/8 and that should be your highest Fuel Ratio Mixture setting—GO TO #3.
IF YOU GOT TO THIS POINT AND NOT INSTRUCTED TO GO TO #3 THAT MEANS THERE WAS NO CHANGE IN RPMS FROM DOING #1 or #2 ABOVE, IT IS TIME TO CLEAN THE CARB:
YOU NEED TO CLEAN YOUR PILOT JET AND PASSAGE AND AIR PASSAGES AND THEN START FROM #1 AGAIN.
IDLE SPEED SCREW:
The Idle Speed Screw on a Carb that are on most 4Ts you will find on the right side on the THROTTLE CONTROL WHEEL. It is the screw with a SPRING on it.
To Lower the IDLE you turn it COUNTER CLOCKWISE to Raise the IDLE you turn it CLOCKWISE.
3. If after adjusting your Fuel Ratio Mixture your idle is to fast Turn the IDLE SPEED SCREW COUNTER CLOCKWISE. For the 50s-150s they like to idle around 1500-1800rpms, for the 250s+ they like to idle from 1800-2000 rpms, pick the smoothest idle with the rear wheel not spinning ---GO TO #4.
TEST YOUR ADJUSTMENTS:
4. Now give the Throttle a QUICK twist and the RPMS should climb up quickly without hesitation or bogging and come down to where you set your Idle at---GO TO #5.
5. NOW take a ride and try it out, the Fuel Ratio mixture may need a tweak in either direction now that the motor has a load on it.
But the tweak will be minor maybe a ¼ turn richer or leaner IF it acts up with a load---GO TO #6
6. When it acts up BACK OFF the throttle about ¼ of an INCH AND HOLD IT THERE:
a. If the motor speeds up it is LEAN you need to richen it up a little.
b. If the motor settles down and or stumbles and then settles down it is RICH you need to LEAN it out a little.
GO TO #5 AGAIN.
Problems with the IDLE:
1. Give the throttle a quick twist:
A. If the rpms drop below idle speed, then recovers (or stalls), it is RICH —Turn the Fuel Mixture Screw Clockwise ¼ turns at a time and go to #1.
B. If the rpms do not drop quickly to the idle speed but hang and drop slowly it is LEAN —Turn the Fuel Mixture Screw Counter Clockwise ¼ turns at a time and go to #1.
..BAD TO THE BONE..
