Got it running! Also, some questions. By globetrotta (Read 590 times)

I got this scoot a bit ago, and rebuilt the top end (had a bent valve), new rings, honed the cylinder, etc. Then I developed a rattling sound from the crankcase so I garaged it for a while. I finally got back into it last week and found that the timing chain guide (top one) was cracked! So I replaced that. Also, the castle nut that holds the starter clutch was really loose. So I tightened that and got some threadlocker on it just in case. So after putting everything back together with new gaskets and whatnot, I put the engine in and fired it up. It sounds GREAT. Much better than before. Additionally, I removed the EVAP system, and redid the whole wire loom to get everything nice, tucked, and tidy. I am SO STOKED. 
Also, my muffler has a rattle so I cut the tip off about 1" in and saw that I still can't get to whatever the problem is, so I'm leaving it for now, it's not really noticeable. But it sounds better this way... A lot meaner.

Anyway, thanks for reading. Here's where I get to some questions I've had on my mind. Any help in answering these would be GREATLY appreciated.

1. A/F mixture.
I've read that I want to adjust it to where I have the highest idle. Does that sound good? Then after that I adjust the idle speed.

2. Charging system.
I have a multimeter, how do I make sure the charging system is working? I just want to check.

3. Back wheel/tire. 
How the **** do you go about getting this on/off? I managed it today but it was a huge hassle, even completely deflated. The engine is in the way!

4. Kill switch/Ignition switch.
Kill switch kills the engine. Simply turning the key to the off position does not. Problem?

5. Any benefits to upgrading stator?

6. Testing for air leaks.
I've read you just spray places with carb cleaner and if the idle changes, there's a leak. Does this work?

7. Fuel gauge doesn't work.
How to fix?

8. Rear break.
I'm having trouble bleeding it. Tips?

9. Oil
Best oil for a 150cc scooter? Motorcycle oil?

10. Fuel/oil additives.
Any benefits?

11. Overheating.
Summer is here and it's going to get hot. How do I tell if I'm overheating.

12. Tachometer
Any recommendations/how tos?

13. Rejetting
Any benefits?

14. CVT cover.
Does it need a gasket, really?

15. Kickstarter.
I took it out, should I put it back in?

16. Fuel Enricher
How to check if it's working properly?


THANKS!

Most of those questions have been asked and answered here already. Maybe Alley can provide links to the tutorials on some of it.

For additives, You can read the thread I just posted today about Seafoam. Damn near magic stuff. Put it in your gas tank and use it a day before you change oil. Look for the Seafoam Miracle cure thread.

Yes, you can test for air leaks by spraying water or carb cleaner all over. Water will bog it down, carb cleaner will rev it up.

For a Tach, I'd get a tiny Tach and hire Glavey to hook it up for you.

The Seafoam will likely clean your fuel gauge problem.

Thanks Guitarman, I appreciate the answers. I'll check out the seafoam thread. And I did try searching for a few of these questions but maybe I wasn't being specific enough in the search. Or too specific.
Thanks again.

1. A/F mixture.
I've read that I want to adjust it to where I have the highest idle. Does that sound good? Then after that I adjust the idle speed.
A. You are on it IN THE TECH SECTION 4T Carb tuning.

2. Charging system.
I have a multimeter, how do I make sure the charging system is working? I just want to check.
A. Connect it to the battery and at idle it should register 12.5-12.7 Rev it up and it should register 13+ volts.a

3. Back wheel/tire. 
How the **** do you go about getting this on/off? I managed it today but it was a huge hassle, even completely deflated. The engine is in the way!
A. YOu did it no easy way it is a PITA.

4. Kill switch/Ignition switch.
Kill switch kills the engine. Simply turning the key to the off position does not. Problem?
A. The key off should kill your motor you have a problem, DO YOU KNOW IF YOU HAVE A DC OR AC CDI?

5. Any benefits to upgrading stator?
A. Only if you drive at night and want better lighting.

6. Testing for air leaks.
I've read you just spray places with carb cleaner and if the idle changes, there's a leak. Does this work?
A. Use water and or carb cleaner and spray individual areas IF the IDLE CHANGES you found a leak.

7. Fuel gauge doesn't work.
How to fix?
A. You have to take it out and see if the float is still good or disenagrated if good then check if the Contacts on the arm are making contact with the resister plate. IT could be loose and not touching or to tight and not moving. Or the contacts on the pivot arm are shot and you will need a new float sensor.

8. Rear break .
I'm having trouble bleeding it. Tips?
A. I take the cover off the and squeeze slowly and it bubbles up and do this until the handle gets harder. Other way is to take the cap off and take the fluid out and then bleed it from the brake side up to the brake handle.

9. Oil
Best oil for a 150cc scooter? Motorcycle oil?
A. Any good 10WX40 motor oil will do, just make sure you change it at least once every 1000 miles. I use 10wx40 Castrol Gtx.

10. Fuel/oil additives.
Any benefits?
A. I Use seafoam for every gallon of gas.

11. Overheating.
Summer is here and it's going to get hot. How do I tell if I'm overheating.
A. If you see the pipe getting blue and or the muffler it is overheating.

12. Tachometer
Any recommendations/how tos?
A. www.trailtech.net/digital-gauges/tto?cat=117

13. Rejetting
Any benefits?
A. If completely stock no, if a free flow filter and free flow muffler go up on the MAIN JET jet at 4-6 size from what is in there, leave the Pilot Jet as is.

14. CVT cover.
Does it need a gasket, really?
A. Not needed they usually rip when you first take the cover off.

15. Kickstarter.
I took it out, should I put it back in?
A. Only if you want a 2nd means of starting if your battery goes dead or gets weak.

16. Fuel Enricher
How to check if it's working properly?
A. Take it out and apply 12 volts to it. It should be retracted when taken out cold and applying 12volts to it in about 3 minutes the plunger should extend out about 1/4 of an inch.


All of these answers and how to's you can find in the tech section, I know I wrote most of the how to's.

Thanks Alley, you are the BEST.
Also, I'm fairly certain I have an AC CDI, I'd need to double check though.
Currently I have all the body parts off, so the dash area wiring is exposed, what should I check for on the ignition switch to kill it?

[Alleyoop]

On the ignition switch check the BLACK/WHITE wire that wire goes to the CDI on the top plug of the 2 plug side of the CDI.
Here is a CDI with all wires labled.

Hey ally, I got it figured out. My ignition switch had the kill wire going to nothing, so I connected it to where it should have been and now turning the key off kills the bike.
