R5 for sale in Colorado

Coleman sent in his R5, which is currently for sale in Colorado:

For sale is a 1970 Yamaha R5 350. This bike runs awesome! It starts on the first kick. The whole bike has been went through, the motor and transmission were rebuilt by the previous owner. I have recently done timing and synched the carbs. The seat was redone using the original pan, and I installed a new (old style) tail light. It has DG pipes and a K&N air filter (no air box). I've put on new (stock) gauges (the milage on them isn't accurate) with working lights and bright background color. Recently changed the oil (Redline) and installed new tires. This bike isn't a show bike, but it runs really good. It is a dream to carve up a canyon and really nice to blow some steam off cruising to work and back... $2500, local pickup only. more pictures available upon request...

Reader Electrical Gremlins

Mike writes in with an electrical question:

I recently purchased a not-quite-running Yamaha R5B, and first off I'd like to thank you for compounding all the information you have! your site has been a major help while I'm working on the bike, and for just learning all I can about it since it is my first motorcycle. I have two questions for you, the first is that the bike didn't come with front turn signals installed, but luckily I was able to get ahold of the correct pair from my uncle. Unfortunately my wiring knowledge is limited to replacing wires where the old ones were, but with your site's help I was able to hook up the brown and green wire clusters to their respective bulbs, but I am not sure where/how to ground them. Both have the eye terminal wires coming off of the bolts on the signals, but I am unsure of where exactly to plug them into. The second is that the bike has a short somewhere and keeps blowing the main fuse off the positive battery terminal. All lights/signals/horn work as they should it seems (except the ones I haven't grounded/hooked up). The bike starts, will run for a minute or so before either dying of a spent battery or the main fuse going. I started checking for continuity, and sure enough there was continuity between the positive and negative battery hook-ups with the key on, started following it back and it lead me to the red wire entering the rectifier. I'm not sure where to go/what to do from there, or even if there is supposed to be continuity through there! Do you have any insight/ideas for tracing the fault? Thanks again for the site, and any thoughts you may have!

Any feedback or suggestions greatly appreciated.

Gearing Questions

Geoff writes in with a few questions on gearing:

I recently purchased my first 1972 Yamaha R5C from a coworker for $100!! (The bike has 11,000 miles on it) When searching for restoration info I came across your amazing site. I am anxious to start riding this beauty ASAP and was looking for a little advice. I am finding that most people start with handling and engine issues. The engine appears to be running well, but I feel I need to replace a few key components (sprockets, chain, brake shoes, etc.) I am having trouble finding concise info on how to gear the bike. Do you have any suggestions on what size front and rear sprockets to use and what type of chain? This is my first street 2 stroke and I will be using it mostly for occasional pleasure riding. Any help or referrals to info would be greatly appreciated!

Just picked up my R5 yesterday. 4418 miles. Shined her up today & took a short test drive. All good. Might change the handle bars in the near future. Your site has a wealth of info... Thanks. Neil

Insane custom R5 chop

Came across this insanely beautiful and meticulously hand-crafted R5 chop on Motorhugger. Interestingly, there's a small inset pic of my very own R5 in the writeup as an example of what "regular" R5s look like. Thanks! I'm grateful to have my bike shown alongside work like this!

A Question of Time

Edson writes in with a question:

Hello Lawrence,

First, thank you for putting together this website. It is very helpful.

I recently (yesterday) bought a R5 350 with a small history - the father used it in college back in the 70's then gave it to his son when he was 10, the bike was stored for 35 years, the son took it to college, a bunch of friends told him they "knew" how to work on bikes and put the whole thing apart and were never able to bring it back to life. Now, the son is finishing college in 2 weeks and needed to get rid of it (in boxes) The bike is in outstanding condition with 3100 miles on it BUT completely apart. I plan on restoring it S-L-O-W-L-Y. I know the engine 'turned' but did not run.

My question to you is, how much do you think (estimate) to have the engine done over? And how long do you think it will take to assemble this bike? I could not pass it on since I always wanted this bike since back home.

I appreciate your advice.

Cheers,
Edson

Edson - I bought my bike off eBay, with no prior knowledge of two-strokes (or motorcycles in general for that matter). I took it to a licensed H-D mechanic, who had recently hired a Japanese bike specialist. It took about $500 worth of sorting, cleaning and replacement of worn parts to get her going again. This price did include things like lightbulbs, tires, etc, so depending on the state of the engine assembly, this figure could be less.

Hope that helps. Keep us posted on your progress!
