I really don't go so often.  I liked it when the 2 stroke extravaganza was at cooks corner.  I remember it was in La Mirada one year and that was cool right up the street from me.  It was driven mostly by the usa2stroker people. That was the last time I saw Doug from Motocarrera.  still have my old t-shirt which by the way doesn't fit anymore.  I think it shrunk lol. :whistle:

These are fun.  Anybody here goes to this?  Used to have a few more RD guys bring theirs but I think those days are over... oh well.

A rubber washer between two metal washer doesnt isolate the vibration enough?  I had to do that with my old SPEC 2s on my RD400 as the welds cracked at the mounts.  I do that to all my pipes now.

I would love too but I am in the middle of a divorce now.  I will be faced with some financial challenges as I am still recovering from the emotional part.  It has become apparent that my hopes and dreams will be put on hold for a while now.  Thanks for the offer though.

Man that is great.  Sorry to derail this post.  Has anybody transplanted an RZ motor in a RD frame?  I know there are LC top end conversions like Marcs amazing bike but I have never seen an actual RZ motor transplants.  I saw at a bike show a banshee conversion in a sport bike frame but that's it.  I assume alot of fab work.  excited to see how your bike turns out well done!

You think this is a problem that will occur on all of them eventually?  I don't know what kind of bonding they are using.  I am assuming it is pressed in and epoxied and over time it starts to separate. I wonder if some holes in the ignition cover would help to cool it down some?  Had mine for 4 years and no issues.

Hey Dudes,

Sorry for the late update but just wanted to let you guys know that the caliper performed flawlessly.  I went to a 13mm master but I think I will go back to 14mm.  Other than that, everything worked great.

Hello.  Thanks everybody on the suggestions.  Pulling the front wheel off first, bolting the brake caliper on to the forks and then putting the wheel back on while slipping the rotor between the pads worked great. In case anybody wanted to know.

Yes, my friend did purchase this from ebay and he went a different route on his brakes.  I suppose pulling the front wheel off is no big deal.  The new caliper is lighter and is made of different material.  It looks of great quality though.  I will get back to you guys as I will test it and see if it meets the performance standard.  thanks again.

Turning Wrenches / reproduction caliper
May 12, 2025, 09:28:03 AM
Hello there.  A friend sold me a reproduction from caliper for rd350 for pretty cheap.  I needed a new one as mine was the original and rebuilt a few times. This one looks to be the same one in this ad on ebay.

When it came time to mount the caliper, there seemed to be interference as I tried to rotate the caliper back down on to the disc.  There must be something slightly different in the channel as the OEM doesn't have this problem.  I compared the two side by side and I can't see any noticeable difference.  I didn't measure with calipers yet but I wondering if anybody has seen this problem before.

thx

Turning Wrenches / 7 plate clutch upgrade
March 30, 2025, 11:54:31 AM
Hello,

I am sure this has come up before and my apologies.  When upgrading from 6 plate to 7 plate clutch is it 6 or 7 steel plates? 

When looking at the parts manual for rd350 there seems to be 7 steel plates:

Looking up the thickness spec they are at 1.15mm. In chucks thread for 7 plate upgrade he uses 6 steel plates. Part number: 360-16325-00-00

Looking at the RD400 clutch assembly just for comparison they use 6 steel plates 498-16325-00-00 but are thicker at 1.6mm.  So the logic is that if thicker only 6 steels are used?

Is it 6 or 7 steel plates for RD350 when upgrading to 7 plate clutch?

I remember going from R5 with chambers to an RD400 with chambers was disappointing.  The rd400 for me was harder to tune and had that flat spot I couldn't jet or adjust out.  It was a more refined comfortable bike to ride but I liked the R5 better.  Had a bud who had a ported R5 with old denco chambers with drum brakes and that thing was unbelievable.  He surprised some dude with a old FZR400(new back then) on the los angeles crest hwy canyon and just blew right past him on the turn.  I feel that the R5 was one of the best bikes yamaha ever produced.

Yeah I put a Vitos crank in my mine.  The lead weights fell out of the old crank and locked up the motor.  This was a few years ago and it's been problem free ever since the install.  I didn't know there was another crank manufacture for the aircooled RD. That's good to know.
