Dust to Glory 360

It all starts by pulling two bikes out of the barn to attempt at restoring first one, then eventually the second back to their former glory.

The other day I had this genius idea of getting an enduro bike to ride around town and into the hills and was considering what my husband and I should invest in. I was then informed of what was hiding out in the barn. My husband acquired a 1971 & 1972 yamaha RT1-360s back in 2004, where they unfortunately ended up being rolled into the barn and stored there ever since. According to my husband, one was top end seized and the other... he wasn't sure about.

I accepted the challenge of restoring one of the bikes for my personal use and eventually the second bike. My husband and I pulled up to the barn and loaded the two bikes and a couple boxes of miscellaneous parts into the truck to take into the shop in town where I can work on them.


A little about myself: I'm a 26 year old registered nurse and the first time I sat on a motorcycle was when I was 20. I was taught how to ride dirtbikes starting out on a little XR 100, then a 1982 XR 200 and currently using a CRF230. My husband and his family all have ridden on/off road motorcycles their whole lives. I plan by this summer to complete my motorcycle endorsement so I can utilize the RT1 360. Now you may be thinking, what's this lady thinking restoring a two stroke when everything she's previously listed are four strokes. But I have ridden (and raced) vintage Hodaka's that my father-in-law owns. Now I will admit I'm the most knowledgeable or savy when it comes to motorcycles, but I do know my limits and I won't let that hold me back. So I'm going to be doing all of the gurnt work, aka the wrenching. My teammates, aka the brains, will be my husband, known on ADVrider as forrest_fire1 and my father-in-law, who both have an extensive history in motorcycle riding and repair.

So I present to you ADVriders, my trials and tribulations of restoring my first two-stroke motorcycle the Yamaha RT1 360. It is my hope to have this project completed by the beginning of summer and at the latest the end of summer. I would love all feedback and encouragement as I document my progress...... and the pitfalls and share them with the world.

And so it begins......

Day 1: The Bikes


Layout all current parts available for use.



Lots of stuff is available to work with..... that's a plus. There's even a third engine, condition..... unknown.

Step 2:
I was trying to decide which bike I wanted to use as the primary bike. The black RT1 was seized and the blue RT1 had it's top end already off to be honed and bored with a brand new piston sitting ready to go in one of the boxes. Yippy, yay, how lucky are we..... Until we discovered the piston was undersized and fell straight through the cyclinder head. So we came to the conclusion that the piston must go with the black seized bike.
So i figured it would be best to just by another piston and go with the blue bike. Now don't judge me as taking the "easy route", I liked the blue color better anyways. So i go researching a piston .75 over due to the previous be .50 over (also per my husbands recommendation). In my researching I'm learning about pistons. Turns out the blue RT1 has a reed setup with the carburetor and I need a ported piston.
It's not so easy finding vintage ported pistons. So alas, i took a break from the engine and investigated the conditions of the two bikes.

So I began stripping down the bikes and getting an idea of what the condition of parts are in.

One of the air filter elements came out in pieces, the exhaust was bailing wire on in multiple spots, drive chains rusted out, battery completely cracked out and one of the seats is torn up. So I began making a list of supplies I would need to get eventually get.

I'm very fortunate that my husband and his father co-own a small engine repair shop, where I'm able to 1- have a wonderful work space for my project with all the right tools, 2- very knowledgeable people around and 3- being able to utilize the businesses contact's to find/order parts.

So my very first order....... I need a repair manual for the bikes.

After I get the manual I will be able to continue on with my new adventure.

Stay tuned.... more to come.

I owned a Yami 360 back in 1982. Didn't have much for suspension back than, but it went like a raped ape.(figuratively speaking ) Rode it for a couple of years, than found a nice can-am so the yamaha sat. Now it brings someone else much joy as it was built up for ice racing.
Good Luck

Hey SFS, we need to get together when they are done and go for a ride and I guess we can bring Mr FF1 with us.

Great thread. Had my own 1974 360 years ago. Couldnt kill it with a stick. It once sat on its side in red clay mud for 18months and was stop seized when we got it up. Took the head off poured some engine oil around the top of the piston and gave it a few taps with a piece of wood and hammer and she came free. Gave the barrel a touch up with some 1500grade wet and dry, put the head back on and it fired 3rd kick.
Got my own rebuild to start in the coming weeks. A 1976 DT250C flat-tracker.

I'm in. Way cool.

When you are done with this, a complete success, black and blue from the kick backs, etc..etc..will you consider starting a class for spouses?
