so i have desmoged re jetted gutted stock exhaust and added k&n air filter. but i still want more!!!!! not alot, but maybe aftermarket exhaust system, a little cam? still want good reliability. anybody got some good mods? i'm all ears!!!

I've done those same mods to my 650L, plus I added an FMF Q4 can.

The next step will be a cam and going up on the compression. The stock 8.3:1 is pretty low.

And, a pumper style carb - Mikuni or Edelbrock would help it out, but would really go good with cam & piston upgrades.

I'll be waiting a while for those mods.

have you taken off your head pipe and cleaned out the weld drool on the inside? one side of mine had alot of restriction, don't know if i'll notice anything, but it can't hurt.

I haven't done that yet. Probably check it out this Winter.

Like you said, it can't hurt and it's another free mod with the right tools.

ya got any cams in mind? hot cams has one for more midrange & topend, don't know what it does for the lowend just wondering what it will do to reliability? put 6000 miles on mine in 10 days goin to prudoe bay an back in 08 an she was bulletproof, got about 12000 on it now. probably won't do any more long distance rides on the 650, that's why i bought the 990 ktm. so it don't have to be that bulletproof.

Stage 1 - Hotcam

It's compatible with the stock rockers and valve springs. I think the reliabliity will still be there, but it's a trade off - performance vs. reliability.

The hotcam will give us more mid-range and top end, making bottom end feel a bit weaker, but a higher compression pistion will cure that!

I'll be waiting for more miles on mine before I do the 10.5:1 piston, hotcam and pumper carb upgrades.

ha backwoods, do you know if anybody makes an aftermarket clutch basket for the 650L? me thinks mine is capoot, after pullin the shit out of it in the sand it was hard to find neutral again. i can find for an R but not a L , will they interchange maybe ? oh ya an clean that weld drule out of the head pipe i honestly think the old girl ran better!!

Just curious what people are running for jets on 650L, stock carb, slip on exhaust, smog delete, sea level to 1000 ft??? Anyone same scenario?

i'm running a 155 main jet, stock exhaust with baffle removed, air box baffle also removed. i ride between 1000-7500 feet.

I had a 650L a few years back and worked it over a bit, I did the Dyno Jet stage 1,Supertrapp and K&N, I also like to run 25% Trick fuel, I use this fuel mix in all my bikes. It really seems to help right off idle and at low RPM, the supertrapp, with the tunability of the disks, for me is hard to beat, anyway set up with this crap helped quite a bit. If I was doing this again today, I'd check into a flywheel weight, and see if an upgraded K&N extreme is available. Oh ya, and try to get 70 or so pounds off it I'll help too....

check out daves carb mods. i did the dynojet jet kit also which giver you an adjustable clip on the needle. also grind off the stop on the fuel bowl so you can turn the air screw more than 3/4 of a turn. drill out the two holes in the slide to 5/32 [ i think ? ] or put in a different spring so the slide comes up quicker. all in daves carb mods. i'm still running the stock 52.5 pilot, an don't seem to have any hesitation issues.

Thanks for the info. Sounds like good mods to me.

Am at: pilot 55- main 160- and 4th position on needle. Seems to be the best combo yet but still have a slight hesitation when I crack the throttle. Am going to try the 58 pilot and see how that goes.... Thanks for all the insight, I am finding it is mostly trial and error when it comes to jetting.........
