Welp inaugural ride was this past sunday. We had it all back together last tuesday and I took it home and put the engine into the frame (friend has limited space right now). No issues, jetting is done and good with AFM, slightly rich-BUT 13:1 and pump with just some VP maddative to be sure and it was good, supposedly with the additive I had 100 octane. Thing never even got hot..
Honestly I thought the power would be a bit snappier-but its likely jetting, longer that stock gearing and the fact my back tires are about 40-50%. It makes some all around good power and is sooo smooth however. The big bore is what I missed as I had previous ones on other stuff. That low end grunt helps soo much when your just screwing around, always makes me think of a 400ex the way they deliver power.
Final build: stock redone crank (friends, mines toast), Pro-x rod (wanted carillo but unavail right now), 43mm bored carb, more aggressive ported head with +1 all around, athena 490 kit with CP 13:1 piston. We also RR the trans gears that were worn out, and I replaced all the rubber hoses. I kept the stage 2 hotcam, speaking to my builder a web would help but for what I do I probably dont need it. Only thing holding me back is the airbox. Im keeping the outerwears style lid, yes it restricts flow BUT the amount of sand it can suck up otherwise is not worth it and I attribute it to what made the last build last so long. After 3 days in Glamis ESPECIALLY! We got back, I cleaned the filter and there was a 1/4 cup of sand that came off it.
I suppose if I get new tires, and change the gearing it might help and give it more of a snap. I have 14/37 as it allows for usable lower gears. May try 14/38 or 39 just to see..
Oh btw, if you havent got one-buy an ultrasonic cleaner. Sucker CLEANED all my glitter out super well, cleaned the cases, etc. Friend has a 5 gallon one he got on amazon decently cheap.
Anyways Ill have to snap a pic to show it off.
