I have an 85 that is getting quite a bit of work done to it. Shaved head, race port on the cylinder, lightened flywheel, FMF exhaust, UNI filter with airbox (or if suggested I could remove the box). The bike will mostly be for duning and some hill climbing in the sand. I might have it in some mountain trails too, but not very often. I live in salt lake city, so operating elevation will be between 4000-5000, and higher when I am on the mountain trails. But, I would like it to be running the best in the dunes. Will the 35mm be too small? Will the 38mm be too big? I would like the power band to be in the mid to upper rpms because I think that is what is best for duning. Thanks for any input.

I have a 34 and a 38 for my 250r. Both work fine altho I'm told the 34 is too small.
I'd get the 38.
FYI: they are running 32's on 90cc motors. Surely 38 isn't too big for your machine.
If you are buying new....I'm a Lectron carb guy. No fuss carbs. I got mine at TC Racing.

 

Are they easy to jet? I was recommended by the guy doing my porting to get the air striker.

 

I told Tom (TC) what I had. He set it up for me.
Lectrons don't have jets but rather a metering rod. Once they are set up, thay are virtually trouble free.
The air strikers are good carbs.

 

How much did you pay for the Lectron?
And does it just bolt right in?

 

I got mine years ago so I have no Idea on price.
Yes, they fit right in.
Call Tom and see what he says. He's the go to man for getting a Lectron set up.

Altho, Tom knows little about computers (ok, he hates them) so there might not be much content to the site.
They are a trouble free carb. A big hole with a needle in it. I've never cleaned my carbs because of a blocked jet type problem.
