I just bought a 2012 xr650l and it starts and runs great until about 4000 rpm give or take (I’m guessing) it feels like it spits and pukes. Also when releasing the throttle the exhaust pops and hiccups. I am calling the dealership to ask if they are willing to fix the problem as I just purchased from them yesterday but I am curious as to what the problem could be in case they do not offer to help for my “as is” purchase. I have read a couple other topics on here that talk about the vacuum lines being hooked up to an air cut diaphram but I don’t know what that is. The smog delete has been done on this bike as well as a slip on dg exhaust and the side cover has a bunch of holes drilled in it exposing the air filter. The battery has also been relocated. My question is what jetting should I have at 2000 feet? I am planning on opening up the carb to see what the idle jet and main jet are and if they were even changed from stock. Also if someone knows about the air cut being hooked up to vacuum and can supply pictures that would be very helpful. I know that the smog block off kits just plug the vacuum holes and the air cut usually gets disconnected. Thanks.

I have an 86 XL600R and I have difficulty starting it when it's very cold or inbetween "room temperature" lets say, and hot. Meaning if it's hot I can start it right up, and on a nice spring morning, i can start it with a kick or two. BUT if its hot and I park to have lunch or stop for a half hour or so it is unbelievably hard to to get re-cranked. Since I have removed the compression release from the kickstart lever it is unbelievably easier to start in any condition, and I have heard of drilling out the choke jet for a little more fuel from it (this taken from a video, i only thought the choke was an airway thing. Any help wold be appreciated, i have no info on jet sizes in it now or anything like that, it is the stock XL600R carb.
I also am wondering what you guys would recommend for Modifications for the bike. IE Guage Change, Exaust, headlight, brake light, ETC. I already have LED blinkers, Pro Taper bars, Partsguy Bark busters, And a UNI-filter air filter.
So I got this xl600r and going over it replacing this and broken that.
Tail lights, brake light all work great-13.7+ V @ battery
But @ a/c regulator only 6-7v A/C and same at headlight connector with lamp still plugged in. Headlight only lights when @ 1500rpm or greater and only like it would if starved of Vac.
a/c Regulator tested and no short
Stator headlight winding to ground test 3.1 ohms
Headlight dimmer switch just completely cleaned (taken apart) and ohm'd out prior to reinstall
Wiring harness connections gone over and cleaned
Stator need replacing? Anyone ever have a weak hdlight output due to the stator windings building less resistance?
