i have my taotao 50cc with quite a bit done so far, and im looking to top it off this weekend. so far i have a airsal 50mm bbk, performance exhaust, a9 cam, 8g sliders, 19mm carb with  main jet, ngk plug and orange coil, and uni filter. so now id like to get these things, but first id like to know exactly what i should get and where the best deal is at. im looking for a big valve head to go with my bbk, but what size and where do i get it?? ebay? i also need a performance variator and clutch, not sure about which clutch springs i should get either, whats the difference? i need some help on which cdi i should buy, casoli blue or gold? iv had the blue racing cdi (not the casoli one) and it failed on me after 2 months and the gold one wouldnt work on my 50, only worked on my 150. maybe a different belt?...you guys are the experts, please help me out and if theres anything im forgetting that would help me get max acceleration and top speed please share! so far iv topped out at 48 gps, with just the bbk, cam, and carb. but im aiming for 45-50 steady cruising at 7500-8000 rpm. also, i just changed from a 92 main jet to a , after doing this and adding the exhaust i just ordered, should i adjust the air/fuel mix? spark plug was burning BEAUTIFULLY before i just upped to the , so idk. it has a little big of a bog after first taking off around 10 mph before i get into high gear if im holding wot, if i just let off throttle about a quarter turn its ok, i was thinking maybe i need a bigger pilot jet too? if so what size?? thank you all very much, i appreciate any and all help |

Scrappy or hoca would be the best choice if you have To have a head now. I would stay away from the eBay heads. If you're wanting to get the top cruising speed up you could also do a gear change. I did a fast read and didn't see you mention that yet.

I recommend the Koso variator, helps keep me in the power band, and has a nice smooth acceleration curve. I highly recommend the advancing angle cdi (not advanced, but advancing) that tvnacman sells (see his banner in the rotating banners above). It not only gives great performance, but also prevents kick back when starting due to not being advanced at low RPMs, but only advancing as the RPMs increase. The only way to get higher top speed with lower RPMs is to change your gear set. You need to know what tooth counts you have now before ordering a different set. Any time you alter the fuel delivery or air flow you have to adjust the air/fuel screw. Both changing the pilot jet (fuel) and the exhaust (air flow) require adjusting a/f. Follow alleyoop's carb ajusting instructions, which also has a troubleshooting part about bog and throttle response. Alleyoop's 4T Carb Tuning InstructionsClutch springs are a balancing act against your slider weights. Stronger springs allow the clutch to reach higher RPMs before engaging, giving you a more powerful takeoff. You may have to adjust your slider weights after changing the clutch springs to get the performance you desire (it depends on riding style, rider weight, etc). |

great! thank you guys, im not messing with all the tear down and having to have new gears pressed in to swap them out tho. i ordered 16/37 or something close to that from ncy and still have them brand new that i got for my 150 but didnt realize what you had to go through to swap them. so im stuck with a 60 dollar final drive set i cant use. i ordered the 1.5 spring kit and hope it does well with my new dr pulley 8g sliders i just got, cuz i cant really afford to order another 2 or 3 sets of 30 dollar sliders lol. i think ill wait untill i have the extra money and just get the hoca head when i can, and if i remember correctly i believe they told me on here these airsal kits run better with stock heads anyways. so as for the clutch, do you think i will be ok with just new springs or what would the benefit of the ebay performance clutch and bell be?..besides better cooling/...and last but not least, what size pilot jet should i upjet to? i was thinking 40? i have an old carb off my 150, i think its a 24mm, could i use that on my 50 and just order some kind of intake adapter or would it just be a waste of time?

also jerryscript, i looked up the advancing cdi's you recommended and there are several different ones, could you be more specific about which one would be best for my setup and that would definately work on my 50? i had a bigger gold one before from ebay that they claimed worked on 50-150cc but it only worked on my 150. im not sure if my scoot is ac or dc, i would imagine its ac, and it has the 2 plugs (one 4 pin and one 2 pin i believe)

just looked at my carb and its a sealed carb so i cannot do any adjustments, will it be ok with the exhaust and the other stuff or do i need to order a new keihin? its burning great right now with the bbk, cam, uni filter, and the 92 main jet..but i just switched in a jet, ordered the exhaust, and plan on getting a bigger pilot jet. |

Pilot Jet - don't change it unless you are having issues at idle Clutch springs - only reason to change them is if you want a jack-rabbit takeoff, the performance clutch bell will not increase your performance enough to be worth just replacing your stock one, but wouldn't be a total waste of money if your stock clutch is shot Carb size - I'll defer to some others here, I run a standard size Keihin Carb being sealed - You cannot do the modifications you want to with a sealed carb, at the very least you will need to be able to adjust the a/f mixture screw. You can unseal them, but I recommend replacing the sealed carbs. CDI - contact tvnacman (a member here), he carries them and tests them before shipping (he tests all parts before selling them), here's a thread about it: itistheride.boards.net/post/49748/thread |
