The Burning Question...?

[giron]

I have posted here in the past work done by ATR. A 3XV frame with an RZ500 engine. That project had to be done over with a 3MA frame. It’s your money and if you like flushing down the toilet is your choice

Hello Jeff B.
It seems from your post that you've either spearheaded the construction of an rz engine or played a pivotal role in financing the endeavor. Could you kindly share your insights and experiences with me? Specifically, I'm interested in learning about the professionals or entities involved, the overall costs incurred for your customized engine, the resultant horsepower figures, and most importantly, your satisfaction with the achieved performance relative to the investment made.
Much appreciated and thank you in advance...

[Jeff B]

Many years ago I built my motor to TSI specs except the pistons. I did all of the work myself. As far as costs, it was just pistons, gasket set, TDR reeds, pipes, 28mm mikuni's, etc. Life happened, 4 kids, poor health, etc. It still isn't jetted properly and I'm pretty sure it has a cracked head. Still no time to dig into it. The little bit I actually drove it, I was happy with the power. No idea how many horse though.

giron,
I've perused your impassioned reflections on ATR, and it appears to be a strongly held perspective from one individual asserting a singular approach to matters.
However, I find myself in stark disagreement. Recognizing talent in any field is accessible even to those with minimal experience.
Your counsel does not dissuade me from considering ATR; the multitude of their accompaniments and favorable reviews far outweigh the negative ones.
ATR strikes me as a highly proficient and skilled entity in their craft.

I hope you will share with all those who posted useful information, a nice build thread to pay forward any valuable and rare information that you find.

I'm thinking about your idea of keeping it an RZ500 suspension-wise, and maybe every other way, except increasing the HP to 100. It seems to me that taking it to 100HP makes it far from an RZ500.

Just voting for suspension/brake mods to match the change in HP. Looking forward to cool pics and blue smoke!

Glad your vision can separate the wheat from the chaff.

Got any pics of what you're talking about?

I saw first hand the work of ATR on the 3XV frame with the RZ500 engine. The way the engine was supported with 8mm bolts from the head. The carburetors were at an angle when the bike was level. That was not good for the float bowls. I'm having two RZ500 engines built. One will be for my RZV500 and the second will be for a TZ250 frame (reverse cylinder). I placed a partial order for engine parts from Yamaha via Japan. Two sets OEM gaskets and eight Yamaha pistons for around $800 with shipping
All I can say is your money but once is done. You will see for yourself.

Here you go again George, slandering ATR for no reason. Let it go. We all know you have a strong dislike for ATR. Maybe it's because you feel it threatens your man crash on Turfrey. Maybe it's because you're jealous because you're not capable of doing much yourself. Whatever the reason, move on. We all know about your obsession with Turfrey and constant trashing of everyone else, including Bill Wilson.

Lucky Mike has made his position very clear.

You are the only person on this forum that has anything negative to say about ATR.

For anyone else reading this I encourage you to search this forum and read giron's slanderous lies when any builder other than Turfrey is mentioned. It really is an unhealthy obsession.

I will continue to make my point so no one gets burned. I saw the bike from ATR. Again the frame that was used was wrong and the engine it was supported with 8mm bolts in the front Why didn’t your favorite shop used rails to support the engine. Do I have to post pictures again to prove how wrong you are. I don’t see a reason why you have to insult me or Brian when all I’m trying to is preventing some on resisting their money.

John
Let’s look at some of the builders in Europe. They properly mount the engines with rails using the engines mounts.
Yes I admit that I can’t weld nor use a lathe. At least I have the intelligence to recognize the proper way in supporting an engine.
I will say the majority of the members won’t put anything in writing but have agree with me

So anyone not seeing things your way has no intelligence?

I think we'd all like to see details here about most members agreeing with you on anything.

I'm not insulting you or Turfrey. What you are doing is using slanderous lies to send business to Turfrey and not to ATR, and apparently now not to Bill Wilson. If you want to fanboy that is fine, but don't do it while claiming other people's work is unsafe or dangerous and a waste of money. You've been pushing that narrative here for years and no one believes it.

When you mocked Dan Neilen's death and said the horrible things you did about him we all saw your true nature.

[giron]

John if an engine has mounts build in the case. Why is it that ATR or yourself think that when the engine uses a different frame is better to tap into the heads for supporting the engine. Don’t you think is better to use the engine mounts by providing the proper support.
It’s not rocket science. I know if you think about it long enough. You know I’m write. Now NS400 insulted me and he started the war and I was not going to put up
with it. On my previous threads here. I never mention Brian once. Why don’t you call him and speak with him. The one thing that didn’t impress me about bill Wilson was the Gus cranks where he built engines and didn’t notice the rods rubbing on the cases

Really? You forced yourself into this discussion and gave the O.P. attitude while bringing Turfrey into it. viewtopic.php?t=17251&hilit=turfrey&start=15

I heard complains on Bill Wilson engines. I sat in a conversation with Bill Wilson and Brian Turfrey. Bill kept trying to get specs on Brian’s pipes. Brian was not going for it.
The interesting part was when Brian was building an RZ500 engine. Brian called Bill Wilson and asked Bill
on Gus cranks where the rods were rubbing on the case. Brian pointed it out. Bill was surprised. Now as far as pistons use Yamaha. Wiseco pistons are junk

Because not all of the cranks Gus had built in Taiwan had rod issues. Most were fine, but some rods weren't sized correctly and hit the cases. Yambits was selling those exact same rods from the exact same Taiwanese supplier. I had a lengthy conversation with Yambits on the subject. Yambits then pulled them from the supply system, but by then some had been sold and used to rebuild cranks and they, of course, hit the cases. The cranks were assembled in Taiwan and then sent to Gus for distribution. Did you expect Gus to measure every single rod on each crank they sent him? I would think that if you're spending $50K to have a batch of cranks built you would assume the manufacturer has provided rods of the correct specification. Why come down hard on Bill for a Taiwanese quality control problem? You know why...because you got to bring Turfrey into it.

I have Gus's cranks here and they are fine.

[giron]

I’ll take your word on the different batch of cranks but if Bill Wilson said it on the phone. He rebuild engines and never noticed it. Then Bill put a case on the bench and place the crank in it. Turn the crank and noticed it the rubbing.
Now be a man and admit the proper way of mounting an engine is not tapping into the heads
