Chihuahua Project, Season 2, Episode 02

Temps are pretty high here in Greece and some missing parts are keeping me back... though I've managed to spent a couple hours on the nf4 project.I hope pics might be of some help to any people out there enjoying similar projects!

Here are the NF4 transmission ratios:  First number for main shaft, second number for countershaft.  1st Gear  17/31 2nd Gear 22/33 3rd Gear 24/31  4th Gear 26/30  5th Gear 27/29  6th Gear 24/24 


Well, there is always time for beer.
Water pump ready. These parts were totally missing.
 Some good plates in.
 Electrics test fine while on the bench. I hope this counts under load as well. Only time will tell.

Cylinder is newly replated though need some chamfering prior installation. The engine came with a  HRC piston that sadly is out of spec but I will keep it for the first start up. I will have to order a new piston soon.

Chihuahua Project, Season 2, The Engine

It's been a while since I've last rebuilt a single cylinder engine and I've forgotten how dead simple and fun it is. The nf4 engine that I have, doesn't seem to be in a very bad shape, so everything should be quick and easy. 
I think I should replace the carburetor and intake manifold with the proper nf4 parts.

So far so good though primary gear bolt and washer are missing; some clutch parts are missing as well. No big deal...
Have I ever mentioned that I hate Yamabond? What a mess... 





Anyway, all newer pics will now be in reverse order I reckon... 
Crankcase is now clean and ready to be reassembled.

Chihuahua Project, Season 1, Episode 02

Mostly working at night, humming along, with a glass of wine. Trying the best I can to slow up and enjoy the process, as the rolling chassis of the NF4 project is coming to an end. 
Not a lot of much interest, mostly bolting parts together, installing R-clips and safety wire. Still some pics look interesting nonetheless. 
Some new fairing mounts were made out of 16mm aluminum tube, mostly to use them as an alibi that I did something more other than just bolting parts. I couldn't justify this post otherwise. LOL
