I am thinking why the bottome end is gone is the jetting right now. I don't have this thing anywhere near close. Once I get it close here at home I will test it out on the sand.

I tried them out on the street and it feels like I gained a lot more top end. Feels like it breathes better up top. I know I was a little lean too on the top end. I was on the edge with the inframes. As for the bottom to mid range I need a lot more tunning or I just lost a lot with the new pipes. I think I am a little lean at half throttle. I have the stock needles in and on the 5th clip. What is the next needle to richen me up around 1/4 to 1/2 throttle. So far I am liking these oof. Now I just need to get them in the sand. I will do some more test on the street to get the mid range to feel right. Also got a question about my plugs. My last set of plugs would not let me stay in the top end. I would hit third then start to bog out. Like it was running out of fuel. I put new plugs in (br8es) and was going to do a plug chop to see where the jetting was with this bog. Well I had no top end bog and it pulled like crazy. Now at the end of the day I started to feel this bog again. Just like it was going lean and running out of fuel. What would cause me to burn through plugs. I take them out and cant see anything broke or out of the ordinary. Should I try a colder plug like a 9. My ignition is all stock.

I got some Shearer Big bores in on trade and was thinking about putting them on the cub. Will this net me less or more power? I know small bores are better and that is what I thought I was getting but they turned out to be big bores so now I have them. Will I lose some bottom end or is the power just not going to be right with these pipes. They are oof's. The is race ported and fed with 39's. Current main jet is 175. That jetting is just right with 50 degree temps and 1200 ft elevation. Since I have the pipes I might just throw them on to see what it does. Just looking for some insight as to how they might do.

I coated the piston tops and domes with the ceramic coating. I tried the Dry Film Lubricant on the piston skirts and that wore off with about 5 min of idle time. With the new pistons I just coated the tops and domes. Then with the cyl walls I applied the PKSX POWERKOTE. Don't know if it gave me anymore power but knowing that it might take a little more heat before it gets to the pistons is worth it. I bought this stuff for my rabbit engine rebuild and had some left over and did a top end rebuild on the 421. Also figure that it might help with a lean issue if one every happened when trying to jet new carbs. The ceramic will take the heat first before hitting the aluminum. I can't tell a power change because when I did the top end I changed out my 35's to 39's and put on some Shearer's from Cpi's.

By all means if you can get them for $400 then get them. I do see that they are raw pipes that are non silenced. $350 is a decent price, $75 of that is for shipping. That is what the last set of pipes cost me to ship. So I could let these go for $250 plus actual shipping cost.

Need these shearer's gone. They are taking up space and collecting dust!
