I'm 6' 3" and 110lbs less than you. I had gold valves and stiffer springs installed in the forks and shock last year. That helped the awful suspension from before.. its still not a lightweight mx bike but better offroad now.

My 07 is a little taller from the factory so that helps. Nobody makes lowered pegs (at least not the last time I checked). Guts sold me tall seat foam and cover, that helps a LOT. I have an inch bar riser on mine and rotated them forward a bit more than stock.

Delkevic has longer units which migh muffle a bit better but I was looking for max power and the least weight.

Next im going to order a Chinese power bomb knockoff to tone down the noise and hopefully get a little more bottom end grunt.

I’m running the stock fueling, no map/fuel mods with super results. Finally I can pull wheelies!
I saw a YouTube video of this exhaust and it was louder but I thought it sounded great! Only thing I don’t like about it is the looks. It’s a bit bland compared to others. But that’s just me.

Only the PC Megabomb lowers dBs in a meaningful way. The powerbombs (PC or knockoff) are too small in diameter to be of much use in noise cancellation.

I weigh in at 175 geared up and so far, so good. I’ve got to get some more miles on it before I decide to dial it in.

awesome guys thanks so much! definitely gonna check out all the links appreciate it.

and as to why i went with the klx over the wr, the dealer had both in stock, its just i figured
1) wr is $2500 more (canada)
2) im not good enough off road to notice the difference between the 2
3) im big enough guy that either bike i would be spending money upgrading the suspension, so extra $ for the wr's better factory suspension would be a waste
4) the camo just looks fkin sexy

all in all spending the extra cash felt like it would be pointless for me

+1 on the going down one tooth on the front. This and this make it way easier.

Hey guys. I just bought a 2018 last week. I'm in the United States and was wondering if our model needs the clutch mod. I only have 8 miles on it so far so I'm trying not to dog on it too much until I get a few more miles on it. I didn't d take it up to 8,500 rpm in 4 th today. Does this mean ours is not restricted? Thanks.

i dont think ours are restricted, at least in the lower gears.
have been over 7,500 rpm no problems

also this looks to be a video of a bone stock 2018 going over 11k rpm and 147kmph (indicated) no problems

Cool! Thanks Oso! I have only ridden mine to and from work 2 times and it's 35 and 45mph so haven't really has a chance to try it out too much. Hopefully tomorrow I will get to put some miles on it. Now to figure out what exhaust to buy. lol. Still trying to decide between doing one with an o2 bung or one without and use an o2 eliminator.

Looked like it was topping out at 160! Pretty impressive compared to what we got in '09.
Anyone slip in a bill blue big bore/exhaust system already?
