honda 400ex 416 big bore kit
all 416 kits are pretty much the same..the wiseco kit is the same as the sparks kit,lrd,powroll,all of them are the same...some might use JE pistons some might use wiseco but all you do is bore out your stock cylinder for the 416..If you are wanting a big bore kit go ahead and get a 426 or 440 kit..you'll be happy either way...ne questions you can pm me..

I'm very pleased with my Wisco 11:1 416EX in combination with the HotCam Stage 2(now being labeled as the Stage 3). I purchased my bored cylinder, piston/rings and hotcam from a guy who never used them for $230. If you're buying them from a parts house you should be able to keep it all under $300 including boring out your cylinder.
In addition to the cam/416EX kit I would recommend buying a CDI that advances your timing and gives you a bit more rev. I wasn't sure if this would offer an improvment on mine or not until I put on a cheap one and it was quite noticable.
BTW, I also did my own port and polish work at the same time as my 416, so I don't know how much of my performance increase was related to the P&P but I suspect most of the gains were from the 416/cam.
