new workshop toy

I am in awe of what some of the people on this forum can do with their hands and brains... 

I admit that I don't understand a lot the majority of what is being talked about in the Technical section, but I'm glad some do and get a hit just out of seeing and reading the posts and trying myself to figure out what the hell you are talking about sometimes.  How fortunate to have all the gurus on this forum, spread around the globe but only a PM away. 

Laverda is in good hands as long as all you blokes keep doing what you do...

I think you should all have another beer now..

Nice job!
It looks like plenty of hours spendt.
How many of your customer is realy after more power? ?
It will probably take a day to rigg an engine and tune it properly. It is of cuorse a good idea to test every engine you build/rebuild to that it is up to the job. I would however guess that most of the engines will go into nice restorded "sunday ride" classics where 70 or 90 hp realy dosent matter as long as the enginne runs smoth?

I would love a dyno in my workshop but since I only have my bikes as a hobby I guess I would get a lot of "friends" wich you allreday get if you have a decent workshop.

You deserv more than one beer, prefebly imported... :D
 
yeah - was thinking about a dyno myself several times. But as I am surrounded by neighbors with a minimum distance of just 10 meters (even if I put it onto the center of my garden), this would give me only about 10 minutes anytime I start the dyno until the friendly guys with these nice illumination on their cars ask me to stop...  :-[

And it would not really make sense to be honest from the cost perspective... A run on a local dyno costs me roughly 40 - 50 ?, even a used dyno without any housing around it cost me at least 8.000. 200 runs until it pays off - I guess that is not arguable...  :'(
 
            l'd be thrilled to own a pillar drill at the moment! Project coming along very slowly, fantastic stuff Red, look forward to

              every post,

Hi Red - Just a thought - as when i was going to set up my Schenk dyno a few years ago - I decided it would be a good idea to have the facility to have the exhaust pipes the other way up - running over top of motor - you can then actually slide a sleeved section in and out and see if power changes as you're doing it- Regards - Phil
 
When we installed the dyno at the Moto Witt workshop, I was wondering, "what the hell do we need this for?"

Once it was working, it was the most versatile tool for finding faults that would otherwise have cost hours of riding around to find, not to mention the checking of repaired/restored engines and the necessary fine-tuning.  Also did a lot of carb mods at the time, roll the bike on, a couple of runs and adjustments and all was safe to let the customer free with his bike without having second thoughts at the back of the head. 

Wouldn't want to be without one, which I am at the moment... :(

Please let me know whats arguable with our hobbies...  :D

Well - my wife is a tax consultant. as such, she is very much into logical decisions and calculations. If you can show something pays off at the end, she is in. If you can't, you are in trouble...

With my bikes I never fail to show her when something is at least cost neutral. F.e. I purchased my 1000 SFC 12 years ago for 11.000 DM, which would be roughly 5.500? today. Even though I invested into a 3-1 exhaust (1.000?), Carbs (900?) and paint (400?) as well as some rubber, rims and brakes (2.000?), the bikes value still would pay back what I have invested (especially if I would sell all parts separately that I have in spare now, like the original rims, brake rotors, calipers etc. etc. etc. ). That is something I can argue with for more bikes. Same with the 750 SF (0) I restored. I ended up with cost of roughly 7.000?, drove it for 2 years and sold it for 7.200? and sold another 1.000? of parts that I had left over. Arguable I would say.

The 1000 SFC Classic I am currently restoring will cost all in all at the end roughly 10.000?, fully serviced and ready to be sold. Might sell it for that price, maybe a bit more - we'll see. At least cost neutral.

The good thing is that with oldtimers, time plays for you...  ;) at least in most cases...

Hi Phil,
When we first started building this toy and after the engine was mounted we were having trouble getting the exhaust system mounted so it would clear everything and so we actually discussed the "over the top" exhaust mounting layout. Finally decided to make a new sub-frame and run in normal position as the intention is to run new engines up on the Dyno, give them a 60-90 minute run in period while we tune them and then do the full load pulls.
Next step after that is to do their 1st service, reset shims, torque head down, any other items that need fixing, button them back up and run them again for another 30 minutes or so.
Then pull engine out of the Dyno, box it up and ship it off.
So the standard exhaust mounting allows us to service the engine while it is still in the Dyno and has been one of the main design features we have tried to achieve.

Was close though, we figured the "over the top" mounting would look pretty cool.

Tchau

Keep an eye on the engine temperature if you're doing 60-90 minute runs. I have my doubts as to whether that fan will be up to providing adequate cooling for long runs at any kind of engine load.

Cheers,

have 2 x analog gauges measuring oil temp in and out plus a thermocouple measuring oil temp out
will be 2 fans running on the unit itself, bottom one not mounted yet
load can be adjusted as and when required
 
I was using a run-of-the-mill Dynojet system to break in our 600 supersport engines many years ago. The cooling fans were good enough for the hour or so I would let them run. Red's set up has the advantage of not having a front wheel and forks being in the way. Unless he stacks up his beer bottles in front of the engine of course. One of the best set-ups I've seen was the system used at Samba Racing in Holland. They made (and hopefully still do) two stroke expansion chambers. They had a 200 liter water tank on their roof and you simply parked the bikes without the radiator on the dyno. Attach water hoses from your engine to their system and let 'er rip. Never any temperature issues and parts changes were a breeze. Another cool toy I had the opportunity to use was Arrow Exhaust's dyno at the track. It's mounted in a tractor/trailer rig so you push it in, attach all of the necessary sensors and simply stand back. The dyno's software reprograms your ECU according to measurements, throttle position, rpm, and load to the local conditions. The only drawback was the thing was then set up for maximum power but not so much for driveability. Adding 2 or 3 percent to the mixture with the laptop fixed that. Old Laverdas should do just fine without having to read between the lines on the results sheets.

Cant use that argument any more. My wife looket through me, I barely ever sold anything.... :-)
 
next few shots
no big items, just a bunch of detail work going on
trying to gain comms with the interface box, either my laptop or the interface box believes it is a idiot
Drikko is on the case, USB to serial port issue, as normal

MarkQLD arrived just in time this afternoon to give me a hand to lift the deal onto its stand
29C today, overcast, Triple M playing, top day to be playing with toys
