I am about to pull the trigger on my weber carb for my 85 brat (ea81).

 

I have heard that there could be an issue with hood clearance with the 2.5" tall air filter. They do make a 1.75" tall air filter.

 

Will the 2.5" work? Or would I have to go with the 1.75" so the hood will close.

 

 

 

Also, I am debating on getting a manual choke vs. electric. Anybody have any comments on that? I love the manual choke on all my dirtbikes. There something about not being able to control my choke that I don't like. However, if seems as if most people doing this conversion go with the electric choke and do not have any issues. 

 

Any reason why I should not go with the manual choke?

 

Thanks in advance.

If your Brat is stock then you will need the 1.75" air filter.  If your Brat is lifted and the engine has been dropped in the engine compartment, then you might be able to use the 2.5".

 

No reason not to use the manual choke, unless you are forgetful and prone to driving around with the choke on all the time.  I have one on my Jeep and it works great.  I did have to adjust the length of linkage that opens the butterfly, but other than that it works as it should.

The 2.5 will work fine. Have on both my stock '84 and lifted '85.

The front edge hit under the hood with the 2.5" on my 87 Brat. Eventually it kind of made the front of the filter deformed.  So they are not all the same. May fit or may not, the short filter will always fit.

Is there any benefit as far as performance on the 2.5"?

Some people will say the taller filter breaths better, I have never noticed a practical difference, have used them both, now I use this air cleaner because it is cool looking. It will fit under the hood fine (oh and the 2.5 inch did hit the hood of my unlifted car as well)
