All I want to do is ride...  The bolts holding on the cover were not torqued down very hard. They were not loose. But that shouldn't have any affect. Right? I tightened the valve lock nuts last time with a ratchet. IN and EX were both .004. I just tried to move them with my fingers and neither would even budge. They are MORE than finger-tight. I measured the gaps just now: IN - a 4; EX - a tight 3. Seems the one that is always changing (3 out of 3 times) is the EXHAUST. I can tighten it more!! I don't know what I am looking for, but I used a flashlight and looked around the arms for some sign of a crack and found nothing. (whew!) My thoughts? Set it at 4 again and CRANK IT DOWN. But - you guys have the experience... What's my best next move? Thanks, in advance!! < Steve > |

WAIT!!!! It ain't fixed yet!!
Thought I would take it out for a confidence ride this evening. I got 3.5 miles down the road and it quit again. It took me 45 minutes to go the 3.5 miles back home. If you want the details, I'll type them out. I believe I have enough experience to know what causes my scooter to stop: it needs a valve adjustment.
No, I have not disassembled the scooter to measure the valves for verification. I can do it later. $20 says it's the exhaust adjustment.
This brings up the question: What can cause the valves to lose their adjustment?
I need y'alls help and suggestions again.
Thank you very much!

Just got back from a 9+ mile ride. (It's COLD - even in San Diego!) I think it's the longest I have ever been on!
I didn't hear anything funny. Let's hope it's fixed! for good!
Again, I thank all of you for sharing your knowledge and experience.
Maybe I can do the same someday.
Happy Scooting!

It sounds better.  They are both set at .004. Hope that works! I maneuvered the hose, thanks John aka tvnacman, and couldn't tell a difference in sound. When the carb was out a couple of weeks ago, I checked the connecting hoses and they seemed OK. Still no cracks/splits. I gots to put it all back together and take her for a ride. Hope it's all better now... I'll update y'all when I get back. I really appreciate everybody's help and suggestions. I want ride this thing, not mess with it daily. < Steve > |

I had to go check. And I took a picture. You're right. But you knew that. ;-)
L to R: | T F | |
With the holes lined up, the line to the left of the "T" is about 3/8 to 1/2" above the mark.
How do I get you the pics? They are jpg and pdf. What do you prefer?

Can do. When I put it back together after the valve adjustment.
Thanks.

Next? The clearances did not move. I consider that a PLUS! I do GREAT work. More edumacation please. The lower valve arm has a little play in it. Yes, the holes are lined up as they are in your video. So-o-o, I go to the fan... The fan markings are: | | F T | I turned the fan to where the mark is opposite the "T" line - the fifth marking. The lower arm is tight at that point...but the three holes are not lined up at all. Which is important? And, where to from here? Thanks! < Steve > |

OK. I heard CLATTER...and I don't think it was the reindeer...
I measured before I started. IN - .003 EX - .002 (maybe) It was tight. Interesting.... Maybe he didn't hold the vslve tight. Who k ows.
So-o-o, I figured I would set them to 4 and 6. I did. It sounded OK. But that was before I put the fan cover back on and the lower hose to the valve contraption. Put it all together; took it for a test ride. After about 2 blocks, I turned around and came home.
So-o-o, I'll change the EX to .005. Yes, I'll measure them first. ;-)
After all, tomorrow is another day!

OK - I have just stripped it down to the valves...for my first time. Came in to verify EX is on the bottom...
Cruiser: I was just getting ready to measure the current clearance. I presume it's at 4&5 already - and still has the problem. The BMS guy said 6&8. ALL you guys say between 4-6. Oh, well. I'm ready to do it.
Reply QUICK if you think I'll break the machine. ;-)

kepps1280: Fuel pump sounds logical. moat: I wouldn't say it dies abruptly. It slows down when it's coughing...and then it dies. I haev a new plug. The mech changed it when he did the valve adjustment. I check electrical connections as a rule of thumb. My mech also talked about the CDI... How do I know if it's AC?  ? It has a 12v battery!!!! See how ignorant I am. Edward from BMS Motors Part Dept said that Valve Clearance should be (00.6 - 00.8 IN-EX). Guess I need to go back in... Still haven't turned it the extra 1/2 turn. Really appreciate all of the help!! < Steve > |

Appreciate all of your suggestions/input. It is still not performing as I think it should. My mechanic told me to take it easy with it for the first 300-500 miles. I didn't realize I was too rough on my little scooter...but, I'll treat it better this week and see if it performs better. Next thought (from my inexperienced mind) is to adjust the mixture. I set it at 2 1/2 turns. Think I'll try three...
And...from the minds of you guys?

Not that I need to say anything...but you guys were RIGHT! The intake valve would not even accept a .002 gauge and the exhaust valve was too far out for the .005. The video was pretty good, too.
Question: Is there a gasket or sealant that is needed when you put the valve cover back on? NONE of the videos I have watched even mention it...
Thanks!

I tried the adjustment ( quasi per Alleyoop). It was more than 2 1/2 turns out. Screwed it in and backed it out 2 1/4. Darn thing quit on me again. It really seems as though it only happens under a load when it gets hot... If I let it cool down for a few minutes, she's fine...until she gets hot again.
I guess hot aluminum would act the same... If it's a valve adjustment, are they expensive? Where do I get a manual or instructions? I'm really not sure I can handle it... :-(
Thanks!!
