Turning Wrenches / Rd350 6th gear in rd400
« Last post by purplecoupe on Yesterday at 09:23:59 PM »
While doing my crank seals I noticed my 6th gear is burnt up. Teeth look worn and was making noise before I parked it to tear it apart. I've come across a place that sells 6th gear for the rd350. Just wondering if I can use these gears in my rd400 trans.

Here's some pics from Chuck's update port, head cut/cc, and squish check.

At the bottom there's some pics from me sanding and polishing the raised lines on the DS7 covers. I used a mini belt sander with 240 grit then hand handed from 220 to 1500 before taking it to a buffing wheel.

5 hours of taping, sanding and polishing.

Got the DT250 a bit closer to the stock trim.  I had most of the parts, but did replace a few fasteners and grommets.  Still need to find rear turn indicators and a front fender.  Anyone have R. Turn Signals or a front fender?

Basically there are "points" coils and "cdi" coils.

If you disconnect a plug on a "cdi" the spark goes to ground through a capacitor and blows the box. With points it will spark a lot, eventually burning the points... and probably the condensor.
Just ground the plug when you pull it out.

You can't run a RZ/RDLC ignition on a RD UNLESS you change the timing by moving the key way 90 degrees.
I think the "best" street ignition from Yamaha was the 1989 Cdn model, the blue one. The timing backs off around 9000rpm, to almost zero at 10,000rpm.

I found some RD400G exhaust pipes. Want them?

Got the seat mounting brackets/posts moved back, it's just sitting on there for the pics. Sadly, the Lucas tail light will need a more vertical mount, to avoid the droop :redface:
Still, the slightly shorter than stock seat looks pretty good, now to get it all mounted properly,w the bobber fender and inner rear to be fitted next.

I measure about 5.5 Ohms, which should be the 4 Ohm rotor field coil plus the resistance of the leads I think.

Battery is brand new but they didnít send me enough acid to fill every chamber, which was odd. It also charged up a lot faster than I expected, so maybe thatís the issue. It stayed above 12V between charging and after all my starting attempts, so I assumed itís good. I didnít actually measure it under load though.

i just use it for setting idle speed. Its actually in the manual for doing suzuki triples this way.  ;)  yes, i leave a spark plug attached to the wire. it really helps with a crossover in my experience, and i usually set it with the spigots plugged on iniital setup.  as far as synching, i always check top of slide method.  works for me.     


that method is really good if you have a stock airbox and dont want to remove the boot.  always more than one way to skin a cat.
