RE: finished the mods....but....
I kept it under 60, I really AM a dirt noob and didn't feel like eating it before a 10 hr drive homeNot to mention the 4000 miles on the stock front 603, that was aweful. I have the 776F now and it does get up on the sand better but I'm going to go towards a soft-intermediate tire when I replace this.

dude, no disrespect in any way with this post, but I gotta be honest with you- at your size and weight your KLX will never appease you. I weigh in at 150 lbs, and had the full gammet of mods sans a big-bore and pumper, and I wasn't happy with the KLX fully. Save your money and buy a real bike like a TE450 or KTM, or maybe where you live you can plate a KLX450 or WR450. It's just my opinion, but wasting money on a KLX to get 1 or 2 horses for a man of your stature is pretty dumb in my book. Now, don't get all offended or angry at me. I'm not saying you're dumb, just that I think it is. Trust me on this one, the mods you're talking of doing will help a wee bit (2-4 horses max), but I can't even see you noticing them unless a 10-horse miracle came out of your expected pipe; and that ain't happening. Not even if it has BG on the side of it.
sorry, didn't see that you already had a pipe. see, what'd I tell ya. I'd skip the 128, move up to a 130 main with the full system.

After these mods I did though, I'm amazed how much power was locked up in there. I'm very satisfied with the bike for now, and probably will be for another year or two. Plus I really enjoyed doing these mods, i learned a ton and found a great new hobby.
Back to the mods. I dont know if going to a 128 or even a 130 jet is ideal now. After starting the bike up again later, it had troubles starting and when i crack open the throttle it stutters once (sometimes) like a "buh-buuuuhhhhhhh" sound. Very quick and no power or hesitation is noticeable. Maybe running rich now with the needle down. I also ride in the mountains so i could potentially get up to 6000 ft too. I think I'll just leave it as is (unless it really gives me problems when i take it into the muck) and have a mechanic optimize it when i park it for the winter....as I just cannot be without my wheels.

RE: finished the mods....but....
Just installed my HMF slip on and it fit perfectly. I have all the carb mods and am getting a little backfiring on deceleration.I also get a little balking the "buh-buuuuhhhhhhh" sound after decel and then cranking on it again.Performance is what I expected and now with the Michelin Starcross tires when I crank itI feel it jump. The sand where I ride is very soft so I am not pulling wheelies but in 4th gear in the whoops I am skimming the tops. Sounds like it should now.
I know I have read the fix for this backfiring and balking somehwere in the forum but I can't find it. Anyone remember the fix? Thanks

See if you have a slight exhaust leak at the header/slip-on connection. A poor seal will cause some popping.

I am getting a blue flame backfire out the end of the exhaust if I rev it up and back off quickly so I assume that is what is happening while I am riding. The stutter or hesitation when I get back on the throttle is the most anoying so far. The pipe fits perfectly and I know others have had some problems with leaking and spacers but mine went on very smoothly.

I saw this on the HMF Engineering website so I am going to open up the fuel screw another turn and see if that helps. "The baseline fuel screw setting helps but you still get popping on decell. Try going 1 turn more (open) if that helps the problem then you DO need a bigger pilot jet, just be sure to re set the fuel screw to the base setting.". I have the #40 pilot jet so it must be the screw setting.
