Hi!

Thank you for a very thorough reply!

Iíll let you know if they do not reply - thanks!

I see that it is some work to do with radiators to make them fit and have the flow needed - I will have to see how it goes with the cooling when I fire it up in a few weeks time!. And I will take from there!

Thank you again!

side air intake is finish... i think 3d printing is getting good as it's a dead bike and anyone can have the info to make/develop parts

on the page 6 post 66 by me on this tread i posted a picture using a rubber 90* for the air intake boot that could have worked but it was crap

---so i got to 3d printing with the plan to make the air boot in 2 parts (split in half so one right and one left side) in hard plastic(ABS) and bolt them together to fit my throttle body and frame

that didn't work ... as much as I could be close to the set up, was never 100% right and it didn't work

---later on i found this material

(Python Flex™ Black
High-performance flexible TPU
3 Customer Ratings
Perfect combination of strength, flexibility & elasticity
Good chemical resistance
Heat resistant: up to 138 į C

the heat resistant is the main goal as most TPU (flexible plastic weren't heat resistant and that's important) it flex and there is no difference then the standard air boot (same)

that fixed my goal as I was able to print it in one peace that would fit perfectly and being flexible as any other air boot

the file I upload It won't fit your bike the side peace will and the air boot top ...the other side was meant for my bike(efi not FCR) and i don't know the angle and length on the original husaberg but with little work it can be reworked

as set up i am using and ender 3 with micro swiss hot end (i upload the file of my set up)

the TPU was printed at 230 with speed of 25
and ABS was at 250 with speed of 40
if i remember them correctly


with this info the air intake boot even out of production it can be remade it won't be the same quality/resistance of the original one i think(it would be like billet vs cast) but it's a really good alternative

ps. i use fusion 360 for drawing file here

Like your work and enthusiasm for evolving your Husaberg with your work. Impressive! Any idea on the impact of ďforced airĒ - experience and or measurements?

I haven't done any measurements...and I won't be working on the bike for a few moths as my house got flooded ....i just done it because with the rc8 throttle body the angle wasn't looking great (it was restricting the air) the side peace i made is also on an angle and it shouldn't effect the flow in any bad way ....but with the standard frc41 and not many modifications on the engine it's not needed

Ps. A friend of mine who raced in the tt with his kawasaki 1000 told me he could get 2/3 hp from the air induction but those bikes do 150 mph so it won't do much or anything on the husaberg unless there is a problem like a restriction


Best air intake are from F1 or those formula student car but they won't fit in the husaberg

If you goggle formula student air intake simulator it show how the flow is predicted


Drc did try a few air boxed i think ( i haven't) he is best to look at ( but he is not using the original frame )
Thanks from bushmechanic and mickey5

Thank you for your thorough reply. Going just for a normal pipercross air filter - bit lack of space with bigger carb, but as I undestood on Taffy it is possible to take off some of the walls on the old air inlet and tilt the carb a bit, then it should fit better.

Maybe Iíll have a look at forced air with the tuning set up I have - but seems to be more work than it is worth just now.

Got a nice offer on tank and swing arm from the guys you recommended, thanks! but I have to test the bike more with the stock swing to see if I really can go for a shorter swing arm given 103 hp in the engine might be light enough on the front wheel. Hope to be following up with post in a few weeks after getting it running.

Nice stuff ...and example with 3d printig tpu is that you could make the air boot for your bike with that carb or it can be used to convert the husaberg to accept any other carb...

Yes making a force air induction it's not beneficial unless there is a restriction

I did try the pipercross filter but it was too close to my exhaust system (i have on both side)

I bought this one and it was fitting well

But you need to get the 50/60? Id version ( the one that fit the od of the carb)

Let me know if you need more info have fun sorting it out
Thanks from mickey5

actually when i was in work i was thinking you could make an angled adapter to fit

i just made 2 quick drawing on cad (really quick) but they give you the idea ....if you using fusion 360 you can easily edit them

and you could contact a 3d printing shop and have the part made (it won't cost a lot) I can't do it because mine got flooded in water and until the insurance pay i won't buy one but i can do the job in the next 2/3 month

also i can suggest to use an hard plastic like abs or other and use an inner tube from a bicycle cut from the carb od to the 3d printed plastic

https://1drv.ms/u/s!AglE4VB8Ec-wv3FV...er9f8?e=dczQk6

it can be done and you will avoid cutting the frame
