what about the base plate movement of magneto. I got new point and I re-wound the hard to find coils 18 and 25 ga. any idea on where I should place the plate to get 0`? I think my timing gauge tab is bent.

I did one better . I used the generator/starter and crankshaft of a 75 . it is a 12v conversion

i converted a 78 dt175 to twelve volt electric start. i got everything machined to make fit . just need brushes a spring and the regulator and i can then test the system out.

i forgot i also found a tank with small dent that is green paint and i think its better than balboa blue

this helped alot . i actually mounted the starter generator on a 78 dt175. had to cut magneto alignment tabs out,had to cut a u shape for the cylinder hump.and a flat spot for the clutch release post, changed crankshaft to a 75, and had to make custom cover. every thing seems to work even had to bend shifter a bit to make clearance . so i think i am good to go.

anyone know the torque value to tighten cylinder studs and nuts to?

1978 dt175 service manual with wire diagram?

this website has only parts fisch nothing with a wiring diagram like in the clymer manual

oh by the way anyone have a dt175e wire diagram?

battery , electronics and airbox will be in the same spot if i install dt400 engine wiring loom will be the same just one less ground wire and red wire is not used dt175 is 7wire cdi and dt400 is 6 wire the red wire of the 175 is not used the wire ends may need to be changed to acomodate the wire keying i do also have to change the the rear sprocket

wiring the cdi is also easy most of wires go to the magneto and lighting coil just need to change wire ends between them and connect to 6v system i also noticed the 400 has 8 fins on cylinder and 175 has 6 the exhaust on the 400 is on the left the 400 has a smaller airbox i found a 400 motor on ebay http://www.ebay.com/itm/130611112019?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 motor http://www.ebay.com/itm/140654878295?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 cdi box http://www.ebay.com/itm/330647195999?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 reed box and boot its cheaper than getting a new cylinder,studs,nuts and gaskets

so it looks like the hard part is fitting it to the frame. i can get the dt400 motor and swap cylinders to make it a 250 the other issue is connecting to the dt175 air box and heat shielding to save oil tank from becoming mush.

is it posible to fit a dt400 engine on a dt175 frame if so how much work needs to be done?

i ended up mounting it straight to the motor

any one have a dt175e 1978 enduro do you know where to mount the voltage regulator the rectifier goes under the gas tank but i have not figured out where to mount the voltage regulator so can anyone help me out? the yellow wire is the regulator connector i just cant locate where to attach the reculator

as you can see i have put some new and used parts on i removed the after market fender and in the photo of rear tire you can see i am missing the turn signal brackets my nine didget vin number is hard to find a report on because in 1981 the hiway patrol made 17 diget vin numbers standard so i was wondering where i can search for pre 1981 vin reports

just flush cut and redrill hole or weld hole sheut then redril

i am not going off road with this bike i am using it for general transportaion yes i am going to fabricate new ones and weld them back on so i can be street legal again i think mine were removed to fit on after market fender the rouned edge probably got in the way i wish they were like the mounts for the front foot peg that spring back in place i go to pasadena city college for welding

i am wondering what the size of the mounting hole for the rear flashers is mine are missing and i need to know the size so i can build new brackets

91701-05050 i got 91701-05055 instead it still fits for the hinge just slightly longer

actually it is used to hold on the oil tank on the 1978 dt175e

just wondering what the diameter and lentgh of the clevis pin on oil tank hinge of a 1978 dt175e

today i put one the wiring harness i had to do this before i put on the airbox and suction tube. i had to shorten the ignition coil wires and the magneto wires as well to make them work with the harness it was long so they could run without a harness. here is the list of part for april i will install 1 flasher 2 78 YAMAHA DT125 DT 125 175 DT175 HEADLIGHT EAR BRACKETS 3 1978 YAMAHA DT175 DT 175 BRAKE WIRING 125 250 400 4 Yamaha Pan Head Screw Lot of 17 Part# 98586-05016 5 1978 YAMAHA DT125, OIL PUMP, AT1 6 Yamaha DT175 DT 175 carb carburetor throttle cable 7 YAMAHA DT175 XT125 BRAKE LEVER AND PURCH GENUINE OEM 8 1978 yamaha dt175 dt 175 enduro y28 rear fender suport 9 Yamaha DT175 DT125 FRONT BRAKE STOP SWITCH DT 175 QS1M1 10 YAMAHA DT100 DT125 DT175 HEAD LAMP UNIT & CASE 11 NOS Yamaha Delivery Pipe Connector 79-81 MX175 DT175 12 90445-05N13-00 HOSE (L200) 2 13 90445-092K1-00 HOSE (L420) 1 so i cant wait till my ssi check shows up on the first
