It was the original ones Chuck but on when he built it.
I changed them again when we went through it last week. I will change them every 2 years now and inspect them when cleaning the bike.
I always try and learn from my mistakes.

Hi Mark,
that is my assumption. I had 2 ripped intake manifolds I did not notice. It had to have been running very lean.
The bottom two rings were stuck so tight I never was able to get the loose. I tried with some picks Chuck had. I have been trying to be nice to it while it breaks in but it is much better that it was. New porting seems to make a difference also.

my motor has been re- super tuned. I spent Friday and Saturday with Chuck.
It is back to what it was plus some more. New port map, new pistons, and some jetting. Plus fixed a bunch of little items I overlooked in the past.

Ordered tires, shocks and some small items to get ready for the gap this year.
Great to have the motor back running great again.

Thanks as always to Chuck. Great mechanic and great friend.

you mentioned it being down on power? If you weren't able to get into upper rev range to clean it out there could be residual 2 stroke oil residue left on crank- maybe that is what you are seeing after it sat for a while? Didn't mention if you are premixing or not and what 2T oil running, but if lower end was really heating up it could certainly discolor your oil residue like that.

The bike would rev clean all the way to 9000. New it was 64hp on the dyno. Felt more like 50. Ran ok. Just not what it was. Plugs perfect color.
Chuck moved the timing jets changed pipes. I thought maybe it's me. 5 seconds on Chuck's bike nope. Bike is down on power. It was originally very close to his in power.
Yes premix only. This ring seems to make sense causing some blow by.
I'll find out next weekend.

Quote from: m in sc on March 28, 2024, 10:52:52 AMi mean.. it could be trans oil but? doubt it in both.

no, the ring should be able to move . say hi to chuck.  :toot:
Thanks Marc I hope it is a stuck ring because that would answer a lot of questions. Also good to know it's probably not trans fluid thanks as always for your words of wisdom and I will absolutely say hello to Chuck and see you next month.

76 RD400. Stage 2 Chuck build. Forged Wiseco pistons. 
My bike had been down on power for a while.
I have an appt with DR Quinzler on the 6th to swap pistons in hopes of fixing the issue.
I noticed when I took the top end off only the upper ring was free. I see a bottom one but it is stuck tight to the piston. Bolts sides. This cannot be right can it?
I also noticed what looks to be oil on the crank does not look like 2 stroke oil.
It has been sitting for months.

That really is a really nice looking R5.

Chuck had a how to at one point, not sure if it is on this form or the old one. I don't see it on his page but it was step by step.

This is, in my opinion crazy cool. Thinking way out side of the box and using existing ideas all the same time.

I personally have never seen this. I have never seen anything even close to this. To me it really shows a great view and sound of riding on of these.

Quote from: IR8D8R on September 07, 2023, 03:18:46 PMNice RD 400.

What the hell is this thing? (Photo). Reminds me of the "Cursed Guns" guy on YouTube. I think I almost went blind looking at it.

Oh. A chopper. Explained here:
https://pipeburn.com/yamaha-rd400-chopprd/

It looks like a lot of the right parts in the wrong order. ...Event that requires a max budget of $1000. Yeah right, there 3 times that in parts alone here. Somebody likes it :busey: To each his own...

What statement does this make to you guys? It's "art". That makes it OK.

second place in not my cup of tea RD.
Number one is that green Daytona that keeps popping up for sale.
