Twin Shock

I would like to see a picture of your drive shaft in a XT 350.

Ok, at least call it a RT3.

Your bike has a Hitachi GS-X170 AC/DC Charging system. Nothing with work without a 12 volt power source.

You have a 1974 DT 125A

How about a serial # that's all we need. The 125's do have electric start. With out you at least telling us the color of the bike it still sounds like a 1974.

32:1 is safe.

If the bike is blue it's a 73. The 74 model is maroon.

Where are you going to race.

364 is a 1974 MX 250, You can get your plastic and seat cover at AMS Racing. E-Bay also has these parts often.

That engine is from 1973.

I suggest you get a good manual "from Yamaha" if possible before you attempt to assemble that engine or you will probably be wasting your money.

I use standard "Yamalube" in my Enduro's and "Yamalube R " in my race bikes. The Yamaha oil injection system deliver's when set properly a mixture of 32 to 1 ratio.

Speed and Sport has them in stock.

You have a 1969 DT1 B. The color is Candy Orange.

That would be the rotor, remove the nut on the crankshaft to remove it. You may want to try and find you a manual for your bike.

There is no flywheel on the YZ 125C. Are you wanting to remove the CDI unit or the Stator assembly.

Still avaliable from Yamaha.

The engine is from a 1973 gtmx 80,first year for the 80cc.

Yamaha still carries the clutch discs for the YZ 80 E Engine.

Good Answer...........

Have not heard of a 1986 TY250 but a 1986 TY 350 yes. Maybe they had a 250 where you are. Bottom line is you have a trials bike.

The Cheng Shin C186 is what I use.

They are on E Bay quIte often but not NOS.

JC Whitney has them but you better hurry, they are about to be discontinued.

The tank is for the AT3 125 but it will fit you CT3. Great price too.
