This is my first build threadunk:!
I have been planning this build for quite awhile and I'm finally starting to wrench on the engine. I pretty much made a BOM for what I eventually want to do with this Grayhound, but it's not all happening at once. I'm not made of money...
This is the gokart:
Before today, the engine was pretty much stock but with the governor spring clipped a bit, a remote gas tank (gravity fed), and the carbon evap canister removed. EDIT:I also forgot to mention that I milled the mounting holes in the coil to get an extra 1.5* timing. Not sure what difference it made, but I did it:shrug:.
I started out today by cleaning the carb and matching the insulator to the carb and intake port.
I took a look at the ports and sighed very loudly. I knew the stock ports on a clone were bad, but give me a break:
I'm not touching the ports yet. I just hope I can sleep tonight with those on my mind. Okay, moving on...
I Dremeled:grind: out the header pipe on the stock exhaust after an even louder sigh. I didn't take pictures of that. You know what that looks like. I going to be making my own header soon.
I unscrewed the jet and E-tube in the carb. I thought Greyhounds came with 95 jets (0.0374"). The jet I pulled out had a 70 on it. A 1/32" end mill fits in the orifice so I know it's not 0.70mm. I guess it means 0.0370". I'm kinda curious about this even though I'm getting a new carb. Please leave comments about this.
The next thing I'm doing before I slam this engine back in the kart is an air filter. I bought an angled 2" x 4" UNI and a velocity stack for my Carbide a few months ago but the dang stack didn't clear the frame. So, I'm using the UNI on my Greyhound and machining my own adapter. I wish it was a 2 5/16" mouth, but I already have the filter. It will be a tight fit, but my measurements say it can be done. I already modified some sex bolts (hehe):glare: to use as nuts. Normal hex nuts wouldn't quite clear the ID of the filter.
