Thank you so much for both of your inputs, I'm going to adjust the valve tomorrow morning and will check into all that you mentioned. My scooter just won't start for some reason, I think it's the valve that is giving me this issue right now so I'll follow Alley's advice on .004 on both ends and will check how it will turn out.  I'm also looking into 16/36 or 16/37 and may just do the swap eventually... ;D |

My stock roller I believe is either 13g or 14g, I never tried the sliders because the final gear were the first thing that I changed out of all the modification that I had done. I would love to see Alley's input for me to make a better decisions and get my scooter where it needs to be. Thank you so much JR. |

;-X LOL! I was hoping you wouldn't say that but I have to accept the truth that is in front of me. I understand about the sweet spot of where the power curve maxed out at 7200 RPM & I would love to be able to touch that spot again, but at this point I would be happy with the 300-500 RPM gain if the top speed will come with it... Questions: If I were to change the gear to 16/36, will I still get into the slow acceleration from dead stop? Is the difference between 12 & 12.5 that noticeable? If I were to place them in the variator, what would you recommend for road condition that I ride if I did go with 16/36, 12 or 12.5 sliders? Final curious question from an eager mind, 16/36 final gear ratio, will that cap me out close to the sweet spot of 7K RPM range or will that drop my RPM cap lower than where I am not which is 6K RPM? This is just a general estimate, I don't expect an exact # but since I don't even know where to begin, I'll take your expert answer than my guess any day!  |

Thank you Ally for the information, I still haven't gotten a chance to test the valve adjustment yet. My scooter won't start today and I had to drive to work, but will check on it once I get home. As for the carb, at this moment it's still stock since I haven't gone into that area as of yet. I do notice that the engine is a bit hotter when I come to a stop at a red light from a decent cruise. I know this is air cooled but I never noticed to feel that hot before, isn't that a sign of running lean instead of rich? Also, should I be more concern with that progress or it's just normal for a long amount of cruise?
JR
Thank you for the information, I will check the tire pressure. I am currently using 835 right now since 842 belt was rubbing on my CVT case really bad.
I did took sometime and research on the gear ratio of what I can do that would be best for what I wanted and I still believe that the set up that I currently have is good for me. I was thinking about 12-12.5 sliders as a replacement but I wanted to acceleration to come back which the 11g did the trick, but I am open to try to get the other sets to see if it's better outcome.
Alley & JR:
I have a question, for me to gain more HP, what would you recommend as to doing so? I know a lot of people would go as far as BBK & if I'm going to adjust the valve, I might as well dive into it. But for some reason I think it might be too premature since I only have this scooter for less than a year and doing BBK would be almost a major modification, I may want to start off minor first but if BBK is the only probable solution then I wouldn't have much of a choice. From my understanding GY-6 that I have from Taotao Powermax 150cc should be producing close to 9-10HP, correct? How much would a BBK push the HP to? If I change the stock intake and exhaust or even carb, will that give me enough power to push the RPM pass 6K without going BBK route? Do you guys have experience the changes and put in in writing of what minimum required HP will do what with specific gear ratio? I know at this point I may be asking for too much & I would totally understand if there aren't such information available, but I figured it's worth asking so I know what I have to tackle to get what I want.
Thanks so much guys, I really appreciate your expertise advice.

JR: Sorry I forgot to mentioned that info.  Original final gear ratio is: 13/40. Thank you for clarifying the limiter, now I wouldn't have to search for that unicorn... As for the gear ratio causing it to drop top end RPM. You are right about the lighter roller weight giving me back the take off acceleration that I lost when I put the new final gear on which kind of balanced things out on the low end. The ride on my commute is mostly flat with a very minor incline on the way home so I only noticed drag for just a short period of time. Now the scooter is 6K happy so if I'm not paying attention it will go to 6K and stay there until CVT catches up to speed. I guess now my only questions would be, is there anything that I can do to bring the RPM higher so maybe I can squeeze the top end to higher than 55MPH? My whole goal for getting the 15/37 final gear ratio was hoping I can get my scooter to top end around 65MPH or so which means the RPM at 65MPH would probably be close to almost 8K RPM, correct? I kept seeing some Scootdawg forum members claiming such of speed so I was hoping to be one of them as well... Alleyoop: I've done that test and when my scooter is on the center stand, I was able to bring it up to 8K real quick, didn't want to go any higher because I was scaring the neighbors.  I haven't tried the valve adjustment yet but thank you for letting me know, I will make that the next task on this puppy. When I ride the scooter it sounds like it has more to give but I feel like it's being held back at that specific RPM mark, that's why I was wondering about the "limiter" from the beginning, I think it still have some power left in it to at least squeeze out another 300-500 RPM, no? BTW, thanks for the info on higher gear oil, I put 85-140W and now the "rrrrrr" sound went down a lot.  |

Hey guys, I have a 2012 Taotao Powermax 150 & this is what I have done as far as modifications: - 15/37 final gear ratio. - Koso 11g variator weight slider. - Kevlar CVT belt. - "Racing" blue CDI. - Orange Coil. - Regular spark plug replacement. - Basic fluid replacement maintenance. When my scooter was stock, it will go up to around 7500 RPM but after the replacement (actually right after final gear process) it will cap itself out at 6K, at best 6100 RPM. This is what I tried: - Replaced the blue CDI back to original CDI, result: slower acceleration & didn't fix the problem. - Replaced variator weight from stock (I think it's 13g or 14g) roller to 11g slider (which is equivalent to 10g roller), result: quicker acceleration and noticed the RPM rise very quickly but RPM caps out at the same, 6K-6100 RPM. I want my 7500 RPM rev back!  I miss it... Any suggestions or what am I doing wrong? I know that GY6 style engine likes to cruise at 6K RPM and it will not hurt the engine but I want that extra "power on demand" available for me whenever I need it. Also, this is something that's always in the back of my mind, whether it's in stock form or at this current stage, my scooter top speed has always been around 55MPH, actually during stock I was able to squeeze it to 58MPH but I'm redlining at 7500-7700 RPM, now it tops out at 55MPH but the RPM is around 6100. I heard about the speed limiter washer that's by the variator but I don't see it, if it was there I would have removed it myself already. Does Taotao scooter (like mine) have a limiter somewhere else? Please let me know and I'll remove it like a bad habit. If anyone of you reading this have the same exact experience but not the same mod, please let me know how you fixed it & I'll try it out. Any suggestions to make my scooter better are always welcome. |

Thanks for the heads up, I am currently using 80W-90, how high should I go up?

Hey guys! New scooter owner with a brand new 2012 Taotao Powermax 150 & so far love how it performs! Of course did regular maintenance but like any other power hungry villians, I want to squeeze more out of it before it pops! Muahahahahaha! I'm starting to get into modding it slowly, so far I have replaced: - Regular CDI, spark plug & regular coil with "Blue Racing CDI", another regular spark plug & "Orange" performance coil from ebay. Result: noticeably more aggressive acceleration response. ;D - 13/40 final gear ratio with 15/37 from Scrappydog in NV. Result: take off response is a little slower which is expected but now my max RPM is no longer at 7500, it sits at 6000 & during deceleration the rear wheel does make this low "rrrrrrrrrrrr" sound so I don't know if it's a "breaking in" period or not?  But so far nothing else noticeable that might be wrong. Ordered but not installed: - 835 20 30 kevlar belt from "Jerry Baker" in CA, they are great people with very affordable pricing. Possible result: longer belt life than regular belts. - 11g variator weight sliders from Scrappydog in NV. Possible result: maybe it will bring back my RPM to 7500 again, hopefully...  Aside from above, everything else is stock or came with the scooter. Any suggestions from you fabulous scooter loving people would be greatly appreciated! I know this is my first scooter in my live but I love this f***ing thing! |
