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  The handmade rearsets were made by Pete from Banks Racing. Check out his work and products at
