didn't know how to title this thread,but i think this belongs here!
i just 'obtained' 2 motorbikes,(i barter a lot!)
one is a 1972 360 torque induction enduro.
the other is a 1980 heritage special 400cc.
these bike don't run right now,BUT!
they have all their parts,are not seized up,and have compression when ya kick them over.
i got these because of their age,and i also thought it would be good projects for my 2 sons and myself
to try to restore them!
now,i ask. did i bite off more than i can chew?
both bikes need a full restore BUT! they have all their original parts,with no damage.
age,and lack of use is the only foe to these machines!
the enduro only has 900 hours on it (for the younger crowd,old dirt bikes measured their use in hours,like a tractor!)
the 400 has just under 2000 miles on it.

if anyone could share any light on what i'm about to attempt that would be great!

i do have an interesting question.
the enduro has 2 spark plugs,but it only has 1 piston! there is a mechanism on the clutch side of the handlebars that appears to 'switch' between the 2 plugs.
now,i'm an old car guy that has had much experience servicing my long list of vehicles,the carburated kind!
never owned bikes,so this kinda stumps me! any help on anything would be great!
thanx in advance
sorry,add on! i forgot to mention they are both yamahas

I am currently riding #11. I've had 10 Japanese bikes and loved most of them, but two years ago I bought my first Harley. The last bike I rebuilt was a Kaw, Vulcan. Found lots of parts here;
It helps if you can get your hands on the service manuals.The good thing about those older bikes is the simplicity of the systems. Even without the service manuals, I have taken old bikes apart in my garage, cleaned the parts and put them back together and had them fire right up. With very little invested other than time.
Good luck, post some pics.

I think your enduro has a reed-valve type motor, famous for oil-fouling the plug. I think that's why they have a switchable, two plug system.

thank you for the tips!

and yes,the enduro is a reed valve! and the fouling of the plugs makes sense!

never seen a two stroke with two spark plugs would like to see pics of that.

tihs is how I start my resto's

always check compression before your buy.

1 clean carb and tank
2 new fuel filter and fuel lines
3 check for spark clean spark plug - new plug if needed and kicker over. fairly simple and works for all motors.

I agree there. I took a look around and I can't find any mention of it.
reficul you might want to take another look at that motor.
You may have this bike; No mention of what you describe.


1972 marked the year when Yamaha first produced engines with reed valves, called Torque Induction. This system helped deliver more low-end power and quicker engine response over the entire RPM range. All 1972 MX and Enduro models had reed valves, except the JT-2 Mini Enduro, which had rotary valve induction. This was also the first year for CD ignition, which came standard on the RT2-MX (360cc).

A lot of first for that bike so, I guess anything is possible.
