Well I think I need gears but I will lower the weight first and do the sharpie thing. The reason I am saying that is because RPM stay at like 7700 RPM till about 60CMPH or so and then RPM climb after that MPH, I am guessing it is because the belt has reached its maxed and thus RPM start to climb...

I called them Chinese MPH (CMPH), because I am not using a GPS. These are MPH and not KPH. My guess I am hitting around 65 real MPH without pushing the limits as of now. I just need George to chime in if he thinks I should change weights or gears  I'll PM him |

pistonguyWent for a nice little run today, she is running strong. I am hitting 70cmph but my rpm are too high, about 8300 when i pull back, i think she has more into her but dont want to go any higher in rpm... I am going to add a one gram, that should bring me to around 7800 rpm. I drove on the highway today and she kept up with traffic fairly easy. take off is very good at around 7400 rpm right now, and it stay to about 7900 rpm till about 65cmph not sure what is the best solution. add roller weight or change gearing? George what do you think? ordered some regular castrol 10w 40 oil coming in Tuesday and will change the oil and finish the break in with that.

Good or bad, I will keep you updated so we all can learn. I am also doing a hard break in. I only put about 5 miles on her now, so I only have about 20 more miles of hard break in. I am thinking at that point I will do the next oil change with regular oil as I put synthetic in now, but from what I am reading regular oil is better during break in period. Thank you

Just did the first oil change after a few miles of break in running and there were noticeable metal shavings so I am glad I did it. I plan to do next oil change in about 100miles?

Hi all, I am happy to say she is alive. I had handy Andy stop by and he got her starting right up. I had an air boble in the carb and a crack in the 5mm spacer. She is running very good. I thought that my rpms might go higher with more power but they are staying at about the same. I only went up 60 cmph for now. She is much faster then before hopefully she will hit st least 70cmph

JerryScript, ital, geh3333 so i put her all back together and i tried to start her but she would not start. I've changed a lot of parts and i put on the ncy 30mm carb as well. I am not sure if its a fuel to air ratio problem. I know the carb was empty of gas, but not sure how many tries would it take. I tried about 5 times enough to kill the battery and put my trickle charger on. anyway i am a noob at this. how many turns out should I set the air to fuel screw at first to get her started?

I think 1k spring is the way to go. I have a 1500 RPM spring and I think I lost some speed as soon as I put it on.

ok, guys quick update. She is all put together for the most part a couple of more puzzle pieces are missing :-) I was missing exhaust stud bolts 8mm  I was able to get the carburetor to fit by using the NCY short intake manifold, however I cant connect it to my air filter. I bought a 2inch coupler today which I will use to connect the carb to my airbox, I also bought come bolts from home depot while I wait for mine stud bolts to come in.... If I am able to get the HD bolts on I will start her up today... How many miles should I put on her before first oil change? I am assuming its ok to let her run on the existing oil from before the upgrade it only has like 500 miles on it.... I was thinking on putting 50 to 100 miles and do the oil change, or should I let her run for a few minutes a do one immediately? I am expecting very big performance from these changes... I hope I am not disappointed  I am thinking at least 13 WHP, but I got no dyno... hahahaha |

i leave the stock airbox in place, if i use a high flow filter i put it inside the airbox with an adapter, easy to drown any of the exposed filters. That is what I did with mine as well. Agreed |

Thank George for you comments. I am not worried about the polishing part because it does not much for performance, it all for looks. Tonight when I am home I will take come more pictures with some measurements. I will also Measure my exhaust gasket and down\header pipe This clean up job was fairly inexpensive and should help a lot. |

Hi guys quick update. I got everything off without having to take the engine out so that is great. I also got my head back. Please let me know what you guys think. they cleaned up the ports and lapped the valves.    |
