here it varies over time. a yr ago UPS was tops, I had a neighbor who drove for them.
then the closest FedEx depot was in Tampa and the drivers were in rental trucks, now FedEx is faster with USPS close 2nd.
That aside, looks like the "in stock" problem is resolved.
look forward to the future posts on this build.

It hasn't been a problem too recently, but FedEx here used to constantly reschedule delivery. Always seemed to happen on a Friday delivery so I'd have to wait till Monday.

The Naraku crankshaft came in a little while ago.  A closer look at the oiling hole in the small end.  It also has oiling provisions in the big end that the stock crank doesn't have.  It has less lateral play in the conrod than any stock cranks I've owned. The whole thing just seems better made to me. I think the extra $25 vs Scrappy's stock replacement was a good call from what I've seen so far. I can't say how it stacks up vs other brands, but I definitely like it vs stock. As discussed previously, the HPC version with bearings included seems like an even better choice at a good price as well if you aren't set on remaining closer to stock specs as I'm trying to. The SKF bearings came in at about the same time from an eBay seller.  |

Cool. I was wondering how this crank would look? Hope it holds up as well...

The bottom end is back together basically. No seals or anything yet.  I heated the cases with a propane torch and slid the crank in. It went well till the end. I forgot to put gloves on and grabbed the case I just heated. Now I have a red patch on my palm that matches up to the motor mount area of the case. Real smart. :idea: I had planned to get a little more done tonight, but I dunno. I might let my hand cool off or blister or whatever. lol |

Got a bit more done. I'll be using a 47mm big bore kit from Autotech355 on eBay to make 68cc. I got it barely used some time ago for $50 and saved it for the project. IIRC it was supposed to have 100 miles or less on it, and I'd believe it. Cleaned carbon off of the piston and otherwise it looks great. Piston rings still have .007" and .008" end gaps.   A couple of views of the ports...   Exhaust port floor sits just even with the top of the crown at BDC. Couldn't get a much better fit.  I setup the degree wheel and measured 184ex/120trans durations. With the cylinder and intake installed, I did a pressure test. Everything was sealed on the first try. I went back to the tuned stock CVT, using the stock variator and fixed half, 1mm stock spacer, 5g sliders, 1,000RPM contra spring, Malossi Tosion Control, and lightened stock clutch with stock clutch springs.  The engine is back in now, but I've done no tuning of any sort.  |

Nice! Good deal on the kit!
184/120 with the supplied base gasket?

No base gasket was supplied. I believe the one I used was around .5mm, so pretty avg.

Pretty sure the 70cc kit will be the hands down winner vs pipe for a first mod on a 49cc for my tastes. I took one quick trip "around the block" (corn fields lol) this morning to see how far off the tune is. 46MPH sitting up at 9,200RPM. So much more torque. To get this kind of acceleration with the pipes and porting I had to use a different variator and keep the RPM up or it just bogged. This will actually pull. I've been riding a 49cc too long, almost forgot how much I like engines that work like they should instead of being stuck in a set RPM if you expect to move at all. I might get more with a different variator setup as I did with the pipes, but it doesn't need it. Doesn't need a pipe to rev more. The stock pipe refused to work much beyond 7500RPM with the 49cc with anything I did. Make it a 70cc and it's doing OK at 9000RPM. Same thing I saw when I used this stock pipe on the 90cc. Don't even know that it's in tune where it should be yet. It's either rich or the 70 degree morning (hooray for storms last night) are keeping CHT low. Max I saw was 290, where I've been used to 325+. I've got an 85 main in, like the pipes used. Already had to lean out the idle mix. It was so rich down low at first that I couldn't keep it running without a lot of throttle. My tail/brake light has quit on me again. Got power to it. Took it apart and it looks fine, no loose or broken connections like last time. I may have finally killed it.  |

Not pretty, but I got a tail/brake setup in place. Hopefully it will work till I can get something better. I had a 194 bulb holder here, so I removed the LED board and glued the 194 harness into place.  A friend worked on his truck here and gave me an adhesive backed LED strip he had leftover from doing a custom 3rd brake light. I wrapped that around the back of the gas tank as a brake light. Prob won't last long since I constantly spill gas when filling the tank. As long as it gets me by for a bit, it's all stuff I had around so at least it'll keep me riding.  |

I swapped down to an 80 main, same as it used as a 49cc with the stock pipe, before coming in to watch the race. Picked up a little more pull. Still running cooler than normal. Prob still needs work. Did the math and the corrected compression ratio with the kit would be 6.5:1, so there may be more to gain there later. Just removing the head gasket would put it at about 7.1:1 and it'd still have about 1mm of squish clearance to be safe. 7:1 is where I was keeping the 49cc and getting good results. Not gonna do it now, just good to know. ;D
