KTM chassis/Blaster engine - BUILD!!

[Roostboy101]

Well finally made some more progress! This was 4 hours ago:

And these I just had to take after all the cutting/welding/mockups...

It does run alot better now and no clearance issues. It seems to have a hanging idle and the power still seems very flat as in no "hit" Everything is tucked in as good as it can get for what I had to work with. Now it's probably time for another break from it or slow piece by piece here and there. Atleast the biggest part is done now - just gotta figure out the jetting yet.

just so you know there isn't much hit in a blaster with a stock expansion chamber. unfortunatly, i would know lol. if you could cut and weld the stock why don't you try it with a cheap used fatty?

Yes but it shouldn't be "flat" it should still have some pep in it.


Looks good! Whats your reasoning for not using the stock tank and rad covers?

If you try an aftermarket pipe I think the F7 right bend pipe would be your best choice.

Ok thanks for all the suggestions people. I just might try a used pipe sometime but I want to finish it first and see what else needs changed before I get back into the pipe.

I cant use the factory tank and shrouds because of the cooling fins. The stock ktm jug is about the size of a softball and the blaster jug is the size of a basketball haha. And that would've reaaalllly limited my pipe options.

This thread caught my eye. Nice work!
What about just using a KTM pipe and welding a Blaster flange on it?
A KTM 200 Fatty pipe would be about right for displacement and RPM.
Just an idea.

I am thinking about an opposite swap. A KTM 250 or 380 motor into a Blaster.
I have the 250 motor fitted into the chassis but the 380 is a bit tight at the flywheel.
I need to learm more about trimming swingarms to fit the wider motor before I cut.
Any suggestions on threads?
