Thanks for fast reply.

I would settle with a decent used one as well, any advice on where to find one in NL?

Thanks for the suggestion, Ejduh.

My friend os more in need of a users manual, rather than the service manual.

He needs some instructions how the release button on the back wheel is used for instance.
Can you support me in this so I can share the knowlege?

Thanks Klaas,
I knew I was up to something impossible, my aim was to build, not to win and I wanted to go my own way wich I did.

We´ll see what happens next…

Hi all of you out there,
I have sold my blue SuperBravo and will spend my time on other objects.
Due to this I will not spend much time here.

I have enjoyed this forum and it have given me a lot of valuable information and knowledge as well as contacts.

Thanks to all and have a great Piaggio-life.

Best regards Ingvar

Edjuh :
Ive seen this engine run with a 78 jet for a few rounds of cross without problems.

Sounds crazy but the adviced jet is 82 i believe.

The power output is much more comparable to puch and others than the restricted 3 stud engines.

Your next challenge would be to fit a worthy transmission.

How about a peugeot fox engine complete…

OK, that makes sense with the inertia.

How about the small canal from the exhaust to the compression release, is there some gain with filling it and making it blind?

I don´t use it and it just puts pressure on the head gasket.

The blind canal may create some turbulence in the exhaust like the blind canal on some new EU mopeds but this…[Lees meer]

Thanks for the input Arvid.

What about the minor leak of the reeds, will that reduce the top end power or is it mainly affecting the low end power?

Thanks for the replies.

I do have a DrEvo because of the race regulations that stops me at 70 cc´s so I had to go with the 43 mm cylinder.

To be picky, I do have an PVL ignition, not an HPI but thye are quite similar I think.

Some updates:
I had the wish to start the engine with a drill machine, at least in the workshop.
It worked well but I found that the large nut went loos as the engine started.

In my garage I had an engine from a grass trimmer with the pull start and I had a closer look to it and found some usefull parts, at this picture tey are readu to…[Lees meer]

OK, lessons learned.

About the inbus, that is the rear motor bolt so that should not be a problem.
Have a look at this picture:

You can see the left side footpeg and to be safe from getting my pants in the belt I put on a cover of carbon fiber.
The two bolts are pretty much in the center line of the belt so I figured it would clear the…[Lees meer]

ArvidW :
The crankshaft of my simo2007 engine survived starting with a drill. However my variator got damaged when the nut got loose after multiple starts. But the compression a simo2007 engine is way higher than a 43mm vespa cylinder so I think you should be fine.

However I think you should be able to start the bike by pushing. There are an…

Yes I think it´s good but I´m still concerened about the crank tap.

Have you heard of any destroyed tap while starting the engine with a drill?

Now the blue one is in one piece:

If you want some more pic´s you can find them here: http://www.camaross.se/Slutmontering.htm

I have made some comments in english that will be visible if you move the marker over the pictures.
Now it´s test n´tune this week and next week, on the 12´th of May I intend to race it, we´ll see if I´ll make it…

OK, that´s worth a try then.

Thanks for reply.

OK, thanks for the reply.

The DrEvos are quite cheap so I may buy another one to do the tuning or to keep in stock.

Thanks, I supposed that was the case.
If there was ways to open the exhaust canal without breaking thru that would be the best to do.
But by looking at the outlet it´s easy to see that the exhaust gasses takes a bend around the bolt.

Will I get any improvement by straightening the canal as much as possible, talking about exhaust…[Lees meer]

DR-felnny, thanks for your suggestion, that may be my choice, we´ll see in some weeks.

beunhaaz, my ignition doesn´t come from a specific bike, it´s components chosen in cooperation with a swedish supplier of those parts.
The list looks like this:

Magnet/baseplate: 1063
CDI/ignitioncoil: 105458
Rotor: 940

This is not a di…[Lees meer]

OK, great advice, thank you.

I´ll stay away from that one and look for others.

The assembly goes on, here from the side where you can see the PVL ignition.
I made the hole large enough to give space for adjustment with no clearance issues:

The ignition is well clear from the holder:

I think I will find another solution to this.
