I have a question about the timing chain. During the rebuild i replaced the chain and also the tensioner. Yesterday, when i checked the valves clearence i noticed that the chain have free play to the sides. if i try to push it up and down, then it's not moving that much. Is this normal? I don't remember how it was when i assembled the engine. Here is a video i made: Looks like somethings wrong, bad tensioner or bad cam? Mine definitely doesn't do that. |

It will work fine without it yes, and it will filter debris, but with oil it catches much smaller debris that may pass through the foam. Always better to use oil and take care to clean it, and your bike will get you all over for a long time. I'm a big fan of doing the little easy things like that. Right now I believe jc53 is running with the air box without the foam filter inside it, basically making it a tube with a box shape that just sucks in whatever straight to the carb without any protection. Yeh , if he is running without any filter , he is pulling a ton of dust dirt and debris I to his carb. It's not as bad as having no air box at all, because it has a couple turns to make, however without the protection debris will surely find it's way into the carb or combustion chamber. I have a few friends who ran without air boxes or filters because they broke. They are really cheap dudes too, so what I did was cut the air box off so there's only the duct, then I put a face cloth over the end of the duct and fastened it with a ziptie. they haven't had to clean their carbs since then and they run really well. |

Come to think of it, I sometimes forget to ask, but did you try cleaning the foam filter or a new filter jc53 ? |

Yeh , I used motor oil last time also because I ran out of the foam filter oil. I like the spray , I used the non spray oil before and it was so thick and messy . but yep , motor oil is fine . your right lain , its used to catch the small dust and debris. TBA , I think the filter would work fine without any oil . the inner yellow foam filter on the uni filters are very dense and will not let much of anything past it " if anything at all ". Don't get me wrong , I would still oil it but if for some reason you have no oil of any kind I believe the filter would work just fine without it. It will work fine without it yes, and it will filter debris, but with oil it catches much smaller debris that may pass through the foam. Always better to use oil and take care to clean it, and your bike will get you all over for a long time. I'm a big fan of doing the little easy things like that.

If it was a foam filter , it may have just needed cleaned . you usually apply a special oil to the foam filters after cleaning them . It sounds like he has the stock box. I just use engine oil on my filters. Didn't have filter oil when I cleaned my filter the very first time a long time ago, never had any problems, so I just continue to use engine oil for my filters. I figure, the oil is used to dampen the filter so debris will be caught in the foam not in the carb, so using a light amount of engine oil seems to work fine for the job and not gunk anything up. |

This sounds really similar to a problem a friend of mine had where he would stall out seemingly randomly while driving. Shortly before he would stall out you could hear clacking/clicking coming from the carb. Turned out his petcock wasn't working right anymore. My theory is the clicking/clacking is the sound of the needle slide moving when not dampened by fuel.

Sounds like you were running rich because of the tune on your carb plus the fact you have a stock air filter. Try one of these: www.testedscooterparts.com/product_info.php?products_id=10566995It should give you the extra air you need plus provide some sort of filter. Right now you basically have a direct line from open air to your carb which is not good, you will have to clean that carb out so often you'd end up getting rid of it honestly. |

Check out my blinkers. Also check out how I hooked up my new uni style foam filter. I made it so you can unscrew the filter right from the end of the hose you will see in the video, makes it really easy to remove and clean!

Worked perfectly. I just cut the regular blinker wires and connected them to the blinker wires. I had to do some custom fitting, ended up cutting a couple holes where the regular blinkers are and I just screwed it in. I'll take pics later tonight.

I have the manual one that fits onto the tank now. I will let you know how it goes later when I install it over the weekend. I don't need anything else right? Just hookup the manual petcock to the filter to the carb?

urbanmadness I have a fan of feelers, not the step-up ones you have. I have all the ones I use bent at the end to get them in at funny angles. Too loud would mean loose valves right? geh3333 There is no visible leak, just the oil level dropping every week, though since I put my valve drain hose all the way up at the top back end of my frame the oil seems to be staying mostly, but still seems to be getting dirty fast. I have heard of other people who get BBK's online with the head already assembled like I did found they needed the valves fixed or something, not sure something about taking them out and putting them back in because oil was getting to the combustion chamber from the valve area. I am starting to think this is my issue. How do I fix it? I need a special tool to disassemble the valves from the head? Were did you have the valve , vent hose before ? My 150 had the air filter box under the front of the seat , and the vent hose attached to the bottom of the box. After installing the uni setup , I left the air filter and box under the seat , and kept the vent hose connected to it. I only removed the intake hose from the carb to the air filter. I've always had it just tied to the frame until recently when I noticed the hose had a hole in it and so I replaced it with a much longer one to put it up back. |

Your wires are tight, but are any of them frayed or sound like they are crispy on the inside when handling them? What about burn marks or exposed wiring? Does it happen every time? What about when you push it off the center stand?

Are you 100% sure the exhaust gasket set in right? I use a tiny dap of grease on the gasket to make it stick to the muffler tube so it doesn't move around while awkwardly positioning the tube to get it on and the nuts on. I also don't tighten the nuts on the tube all the way until the muffler is secured to the frame and the tube. I only tighten them until I feel resistance in both nuts, then I secure the muffler and finally end with finishing off the nuts that connect the tube to the engine.
