Boy, that cat wasn't restrictive at all... How's the power now? Do you plan to re-jet? |
Since I was wrapping it, I didn't smooth the welds.
I think the plug welds were to hold the cat material. After I welded it, I plugged one end, sprayed soapy water on the welds and blew compressed air in the open end. My new welds were sealed, but two of the 3 existing plug welds were leaking and needed a spot of weld.
I'll have to wait until my son rides it for a report on any additional power. My brief post re-assembly spin was my first ride on it.
I suspect I will have to rejet. It is running too lean and needs almost full choke to go to wide open without sputtering. I haven't looked at the carb yet, are there any mixture screws?
While I had it on the lift, I also cranked up the rear shock to get a little more seat height.
