DT 300I 15.4 or .5 gm .. I know this because I weighed them!
      350i  13.0 gm  ..  I will wait for Ruffus' confirmation!

You are entirely encouraged to experiment all you want because that is the nature of hot-rodding in most of England, USA and Australia to name three. Cosworth of England to name just one, the great Cosworth-Ford soup-ups that went into the Lotus-America thing I drove ONCE in about '63 and scared the ***P outta me! USA full of hot-rodders like Edelbrock, Hedmann, Mickey Thompson, Iskenderian who are a few who made business of manufacturing "speed goodies" for us greasers to spend money!

Burt Munroe from either Australia or New Zealand, the reclusive genius who cast his own pistons by carefully sculpting the female form in the ground near his shop!

You may be next!

As written before: too light!
Weights are originally 15,4g 20x12 mm.
If you go to 9gr, you get a wailer unheard.
https://ibb.co/g4WJnRm original oem parts 13 gram!

Downtown 300 / Re: Oil leak from rear axle/transmission

This hole is supposed to be an indicator
 (by showing a drop ore more) that your rear axle/transmisson oilseal is worn out.
Means wheel off and renew. Axlebearings in your swingarm are to be checked too and if neccessary, changed.
to replace the oil seal is must to open the transmission bolts from inside?

Downtown 300 / Re: Changing rotors to my downtown 350
« on: June 24, 2023, 04:36:59 AM »
@Yoni159 welcome here!
On rotors and breakcaliper bolts its adviseable to use blue @Loctite because of vibrations on this items.
Torque wrench not necessarely if you have some experience with tools.
so how to tighten the bolts without tourqe wrench? 35nm is really tight?

Honest answer?  I'm out of my comfort zone now.  Presumably it couldn't hurt to check both, but hopefully someone more skilled than I (Crossbolt?  Ruffus?) will pitch in and advise.
someone here was right i checked it very good and its front wheel bearing. I glad it is because its cheaper to replace. Something strange is i replaced them 2 years ago

A quote from someone who appears to know more than me:
“ They could just be loose. If you don't get them tightened up, they WILL wear out quickly since they are getting hammered over every bump.

If you elevate the front end and tighten the bearings like the shop manual says, the bars will "index" if the races are shot. What I mean is the bars will turn about 10 degrees and stop, require more effort, then stop again so your steering feels notchy. This will eventually affect handling in a very bad way.

I would see if they behave after tightening. If they don't, I'd replace them in a heartbeat.”

My advice? Take the bus until you can afford the repair.
Which part in need to tighten?
