Hello Howell....John Davies asked me to tellyou that their 500/4 managed a fantastic 2nd place in the Classic TT Senior race. William Dunlop lapped at 109.4 mphon his final lap with 138 mph max recorded speed on Sulby straight. The Paton was just toooo fast but realistically this was the best result possible! To put the speed in perspective Hailwood lapped at 108 mph on the rc181 :-) Alan Oversby retired from 6th on the final lap but not before he recorded a 107 mpg lap on his 3rd time round. Bit more power and it cud be one step higher!

Here's a Youtube compilation about my son's last races on the Honda CB500  in 2012 before his terrible crash.

Howell,

Thank you for sharing...
Great compilation. I enjoyed it very much. The pucker factor is much higher watching racing in the wet for me...takes a larger set of brass to push the bikes hard in wet weather. But, I guess the water provides a lubricant if you do go down...as long as you don't hit something solid...

I hope Yrjo is doing better.

Hi Rene. I watched this on F-book the other day. He sure looked good, it's a scary shame the way it ended. Hopefully you both are doing well.

Yrjo had again a surgery last october,they have have put some screws in his left  foot to stabilize it.
His leg is again in a plastercast  for some month.About a week or three the plaster will be removed.
We hope that he can almost walk normally then.

Wow, that some crazy hardware. Here's hoping it helps him get around better.

Ouch! X-Rays like that always freak me out.
Sorry to hear about your sons injuries. Hope he heals up fast.

I will keep him in my prayers. That last shot shows the bone (small one) not even attached...misaligned with the break. Surely they fixed that.
That is some nasty looking hardware, makes you cringe looking at that stuff. It has to be unpleasant and hurt.
Keep you guys in my thoughts as you care for Yrjo during his recovery. I hope that he is able to achieve the normal walk again that would be outstanding!!

Last year I build a Honda CB550K3 caferacer, see the pictures.
Now it is 602 cc , I used the cilinderblock of a 500 and sleeves from a 650 and 61,5 pistons .
Also the cam of a 650 and the carbs, took me some time to setup the carbs well.
Frontfork is from a CB750KZ and also the calipers.

That turned out nice, it was quite a change from the original you started canvas you started your mods from... 
I would imagine it is pretty quick and it stops well. 

Was it fun to build?

It was fun to build,but I don't know how fast it is, I just did 20km(15mls) on it, braking is good.
I build the bike to sell it.

Sold my CB750K2 1973 last saturday and bought a CB750 Seven Fifty Japannese Edition, the only one in the Netherlands.
I bought for two month ago also a Honda CBX750F2.

This is a great thread, but it sure would be even better if folks could fix their broken image links! I've always loved my heavy-weight DOHC-4 stuff but it's these lil' guys that are giving me a greater appreciation for the light-weight SOHC bikes, far more so even than the 750's - I'd love to try my hand at a CB350F someday.....

Upon further reading, might I just add - very sorry to hear about Yrjo's injuries. Specifically. The crash, well - THAT'S all a part of racing. I can look at a thousand of these bikes being crashed, at ALL of our bikes being crushed and know it would only inspire us to rebuild 'em and build 'em even BETTER next time. Even the rarest Unobtainium parts of ten years ago which we see being re-produced and for cheaper today, only proves how much things could be IMPROVED by smashing each and every one of our bikes! But a person shouldn't have to get seriously hurt while racing, just to make it exciting for the rest of us, to help us all get our adrenaline rush. Not PERMANENTLY anyhow! So here's hoping Yrjo's mended up as nicely as a bike can do. Having dealt with some accident injuries, some disability and some 16yrs of round the clock chronic-acute pain which heavy doses of narcotics can't mask, I can certainly appreciate what a difference each and every inch worth of recovered abilities can mean. I don't know you from Adam, but I admire what you've done here and surely there's gotta be truth in "you meet the nicest people on a Honda" - So I'll go on the off chance that you're not a horrible person and wish you all the best with recovering. Sounds like a horrific injury. It's almost enough to put one off about this whole project of yours. But what a hell of an achievement what a hell of a beautiful beautiful bike. It's a thing of beauty to race a bike like that. I can accept the risk of sudden death. But of long-term chronic pain and disability? Going through #$%* like this can make you question EVERYTHING you've ever done every risk you've ever taken. Well - suffice it to say, the #$%* I screwed up MY health for were a lot less worthy than your bike! Those fleeting heights can sustain one through the most deep & prolonged lows. If only we let them.

'Cause it's one thing to "live the dream", another thing to dream it - but something else entirely to REMEMBER the dream once it's turned on you and bit you with more than just a nip in the ass but really tears you in two. My own problems are the result of a whole list of incidents, but the 1907 house my first-wife & I were fixing up when my back truly #$%* the fan, well - now I can't even LOOK at homes & architecture - would live in a tent if it weren't such hell on my back sleeping in one ... more to the point if I could stay awake 24/7 (AND stay alert enough not to hurt somebody - which is to say being kept away 24/7 hasn't proved that difficult these past years), if I could I'd live on the seat of my BIKE ha-ha. If only to avoid having to look at those lovely old homes & gardens which once seemed so appealing. Which is to SAY, I hope this hasn't done the same for Yrjo with respect to BIKES! Now that would be the real tragedy.

-Sigh.
