Lightbulb Tommy's Tips: Intake/Exhaust Blocks

I don't know why but everything Baja takes days rather than hours. Another observation is that there is -never- enough workspace available. With these two very annoying realities, how often have you wondered if that flying c-clip, body clip, snipping... or whatever, found a straight shot right into your engine through an open port? If you never have, you never tore apart a motor or even rebuilt a carb and this post may just be a waste of your time... unless you are an addict as most of are and just -love- reading this stuff :alarm:

Anyway, I was in the middle of rebuilding a new motor and found myself snipping aluminum mesh right next to the motor... and you guessed it... I -wondered- where the spillage went. So when I did finally take the whole motor apart I also made a few tools to help seal the thing off while I was working with it.

I happened to have some fiberglass sheets that is only .025" thick. It cuts up nicely with shears and drills well with a simple finger-drill. So why talk about something no one has... simple... you can even do this with some stiff cardboard, stiff plastic sheet, or even wood if you are so gifted. The tip here is how you hold it in place!

I used a stock gasket as patterns for the holes and edges; trimmed and smoothed the edges with a file; and installed them between the cylinder and the manifold/header. They are only here to protect the engine from flying debris and can be removed just before final assembly of the carb and pipe.

Enjoy the peace of mind that the motor is clean and ready to run when you fire it up.
