Default Blown 45 build

Hello!
The build season is comming up here in sweden and my 45 is up for an overhaul again. I built it from an pile of parts from what must have been an seventies chopper.

Attachment 80272



After the first winter it looked like this
rather bobbish


Attachment 80273
Now i been drawn to more of a dragrace style.
The idea for now is to make it blown but maybe i go for a more radical N/A engine. Time will tell.
Hopefully i will have enough time and money to make this happen til next summer.

Thanks!
Nice is nice but i rather go for badass in terms of bikes.
If i where able to sell anything that i've made i would have sold it and start over with something else. But i can't....

The build season is the best season by far. This is what this hobby is about for me.

Transformation has already started. At the end of the summer it had 6 inch over springer but i have shortened it til original length.

Then i've dyno it to se how much air the engine consumes on it's own and how much it revs

The next thing is to determin the location of the blower. which affects pegs and pedals etc etc.
under the seat is the most natural placement. or in front of the engine.

First problem is that my Eaton m45 blower is to long, so the snout has to shortened as much as possible.
Hopefully i can get around to that this weekend.

Forced air 45 ? Thats like a 80 year old man runing in the New York Marathon . I'll be watching this build with anticipation of flying parts.
Its your bike . The Bobber look was killer.

no matter what you do ,make lots of pics and post them

i've been thinking of building a blown /compressed "45 ...but i think it will break into pieces
that's why i decided to build "45 engines with matchless G3 cilinders and heads instead

(you can do a search here on cees fick /kees fick and you will find a thread and pics !)

but hey be my guest > i like special "45's and builders who think out of the box when building something redicule and fun !!!

So it was your bike in 45pic thread with matchless cylinders!?
Thats radical! Hats of to you.
I've thinking of such radical mods my self but doing some serious stuff in the past i know it doesn't work with small children and house restoration's.
it simply takes too much time.
But then i grow up to be an greybearded old bugger i will have an fully equipped machine shop in the garage and all time in the world. then!!!

That i must check out.
I've been doing an tuboconversion of a japanese fourbanger bike before.
It took me 2years to get it all right. But man, that thing is ludicrus fast.

This will be more of an show off bike at the local hot dog stand. (swedish expression)
More show than go, to keep the engine together

Maybe the blower generates to much heat so the bikes overheats and seizes. Thats my biggest concern, or the cylinderwalls are to thin, so the cylinders cracks.

Keep the boost low or run lower compression. As long as the mixture is correct and air moving over the fins, it should live.

This weekend the projekt was to shortened the snout. I got half way through this projekt then i realized that my work only had the inserts for the internal groovetool not the actual tool.
Well, i finished turning the new bearing surfaces which where the hardest part. Hopefully i can finish this by next weekend.

Lower? Im already down til 6:25 comp ratio.
But i am a bit anal about afr ratio's.
I'ts stupid to build an engine for a lot of $ and then seize it beacause you run a lean mixture.
