Moriwaki Stage I engine
I bit the bullet this morning and committed to buying it.
My SH has a failed Rod bearing. This is a rather simple fix. Since I have to pull the bike down this winter, I started looking for upgrades. For all tenured SH owners, who is the man when it comes to the SH/FS? Roger Ditchfield, of course. I contacted him regarding his engine upgrades. He responded to inform me that he had a COMPLETE engine available. I responded this morning with a commitment to purchase the engine.
Here is the list of items on the engine:
Yes, it comes with custom carbs. The only part I have to transfer is the starter.
With the new job I will have more time and funds available to get to some track days and exercise her properly.

That's awesome... Be prepared for a world of difference.. After riding my Stage 1 motor(more like stage 0.75 compared to yours) and switching to a stock superhawk for a bit, the motor makes it a completely different bike.

98VTR, I'm hoping so. I love this bike, through and through. This should serve to amplify the other changes I have made.
I have a modified (braced) swingarm ready to go on, Andrew at Little Horse Cycles did the custom brace for me. I already have the GSXR front end. A trip to Computrack to have the suspension tuned will be in order.
The price is a huge commitment, but I think a zero mileage motor will make it all worth it.

My engine is a somewhat similar spec and it cost me a few $$$$ to build. As Markus (Tweety) said, parts are getting every more difficult to find, that is when they are even available (bike has been out of production for 6 years now, and truthfully, was never a superbig seller anyhow, its sporting pretensions having been usurped by the RC51 a short three years after it was introduced). As for this specific engine, it was put together by "The Man" himself, Roger D, so you know it was well done...
Methinks you'll have a lot of fun with your upgraded VTR

Mikstr, you hit the nail on the head. It's a zero mile engine built by Roger. Can it get any better or more reputable than that?
What did I pay? Well....£2000 plus shipping. I'm figuring between $4000-4500.
I happened across it at the right time. That is how I'm getting it. I contacted him about his engine packages and he offered me this engine.
I am most curious to see the custom carbs that he mentions in the email. Looks like I'll be going back to dual exhaust, just have to go to a custom high mount.
Nath, you are too funny.
Thanks guys, I'm anticipating a lot of fun riding.

Yeah i am funny and Ruv claims I am "the king" too. The question is, can you be a king without a kingdom cause i can't find mine?
congratulations on your purchase. Was wondering what kind of CCTS? And are you going to do any swingarm and/or frame bracing to handle all that torque? What mods does Roger recommend for this?

For whatever reason, it didn't enlarge the last two pictures. Here is the link to the folder with the pictures.

I am definitely open to ideas, and will be contacting Roger regarding this.
All input is appreciated. At this cost, I don't want to have more down time due to something that could have been avoided.

Zxbud, thanks for reminding me. I need to ask Roger if I can use the machined velocity stacks that I purchased from Dr Honda. I don't believe that it is coming with an air box, just the "custom" carbs.

I'll be writing Roger in the morning to inquiry about some of these questions.
I know this much, I'll be going back to factory gearing. LOL. I'll have plenty of HP and torque.

I wondered if someone already did fix this issue with the existing design.

Honda Cam Chain Tensioners
I know that 8541Hawk has the very high mileage on his and I think VTRSurfer is high mileage, like 60+ with stock.
I also know I read alot of failures here on the forum. I've asked this before? What gives, what's the variable.
Is it how the bike is operated? I think both 8541Hawk and VTRSurfer are running above the posted limit! Is it wheelies, just plain hamfisted throttle/braking cause major chain tension/oil pressure fluctuations?
I have a set of Kreigers (uninstalled) and my bike has been run hard and put away wet by the PO and I'm still addressing those issues. But frankly I like the thought of auto adjusters so I'd really likel to get a handle on what the fault is.
Tweety before you go off on me, as an engineer you know it can't be random! There has to be something.
