I believe I read that the carb float bowl should be level. How important us this? I've seen many on here that look as unlevel as this. When the engine sits flush on the frame mount and with filter on. It's like this. I do have a RSE reed valve as well. Any suggestions on what to do?
Thanks

it helps, but it's not as important as people say. you should be safe leaving it as is.
 
Thanks and good to know. I'll try before final mount to improve some but at least I don't have
To start throwing away parts etc... Lol
what's the disadvantage?
Thanks

Butre is a good guy and all, and he is not wrong, but in my experience, I'd level it or you will forever be chasing your tail.
About 5 years ago I stuck a bad arse KTM 250 motocross motor in to a little itsy-bitsy Yamaha Blaster.
This was the BADDEST KTM 250 made in the era, the feared 2003SX that killed Jeremy McGrath's motocross career.
It came with a widow-makin' 10hp light-switch jump in power at 6000rpm. Just what a Blaster needs, too much!
I digress...

So it was a tight fit and I angled it a bit to fit, including the carb.

Not such a bad angle, besides, the acceleration will make like nearly level right?
The theory is you just adjust the float level and jet it for this position. WELL!
You do not have enough time in life to get the bugs out of a crooked carb. LEVEL IT.
I'm not a dumb guy, and you don't need all the woe it took for me to get to this life lesson.

Works MUCH better like this.

Works so smooth now, I can relax on outings...

I'll have to figure this one out. If I chopped the engine mount off, I could go directly on frame and adjust up or down to get level. Sort of beats the 2nd reason I bough the frame" to have a nice clean look. I'm going for looks as well as performance hence the last pipe thread I posted. :)
Nothing's ever simple!
Thanks Steve
 
I see the problem with the carb. Not much room to angle it.
What about using a 1/4" aluminum plate to move the front motor mount up and forward?
Use the blocks on the rear mount to get the carb away from the seat stem tube and it should level?
Otherwise, it is going to be some sort of intake adapter.
I gotta say I liked the tipped forward look.
It is a very nice looking frame.

Just change your intake pipe to make the carb level.
It is a gravity based system, floats don't like un-level, neither does the gas intake pin that controls fuel.

You can dink around with float bowl level all you want but at best you have enough fuel in the bowl at high RPMs and get sputtering, but most like likely you will get over fill and when off or at idle overflow just dumping raw fuel right into the crankcase.

You engine mount to the frame is perfect and that is most important thing, just change input manifold until it's level.
 
Those reed valve intakes were designed to work with a diaphram carb, such as the Walbro that Fabian is so big on. With a diaphram carb, the engine can be at any angle, chainsaws and weedwackers come to mind.

So does this mean I'm fine with it at an angle?my carb is the Dullar.

Kc,
This what I was thinking as well. Any suggestions on where to get a different intake for this angle? It would have to attach to the reed valve and then the carb! Correct?
