inline filter on klr 1989

[Brad]

1. How many of you have done the drill the slide and shim the needle? Does it make that big of difference? Should I do it? 2. Reading my Clymer manual this carburator looks quite complicated. Do they give much of a problem? 3. In Oct I'am going to be in CO Springs and would like to go up Pikes Pike. Will a stock bike run at 14,100 feet? Thanks Brad 2009 KLR

Hi Brad,   1) Did the carb slide drill and needle shim, also drilled out the mixture screw plug so it could be ajusted. The screw on my bike was about 3/4 turn out as opposed to the 1 3/4 turns that seemed to work the best. Very simple job, just have to be very gentle with the throttle and especially the choke cables when you rotate the carb to get at eveything. Bike doesn't pop on overrun anymore, gets about the same gas mileage and seems to have a bit more pull by the seat of the pants, just enough to notice. Slight trade off seems to be a bit more abrupt when off road on tight trails in 1st geat with stock gearing.   2)Winterize the fuel system before you stop riding the bike for extended periods, use the odd can of Seafoam, and in 4 years I've had no issues, carb is as simple and reliable as they get.   3)Nothing around me anywhere near the high without wings.....Greg

I have installed a few jet kits in my day.  Drilling the slide won't effect the fuel mixture but will change the speed at which the slide reacts to your throttle input.  It's a vacuum port in the slide that you are enlarging.  This will make your bike feel like it has more power because the slide opens quicker.  Shimming the needle will enrichen the midrange where you drive most often and should allow for a slight power increase along with a slight decrease in your fuel mileage.   Your bike runs pretty lean most of the time and going up in elevation will help richen the mixture but because there is less oxygen at higher elevations you will feel like you have less power.  The KLR with the stock carb should run ok for a short duration at elevation.  If you are going to live at higher elevations then it might be a good idea to rejet for this elevation.  Just be sure if you go to lower elevations that you will need richer jetting or risk the chance of major engine damage.  Just ask Lew Waterman. (Punky n Lew)  Anybody remember them?   The stock carburator is actually pretty simple compared to some other model  bikes.  It is fairly reliable and shouldn't give you any trouble as long as you keep clean fresh gas in it.

I do. I had some dirt that would get my float stuck, so I found this little 90* filter that I just put inline after the petcock and it works wonders. Some people complained about fuel starvation, particularly with low fuel levels, but I haven't had any issues. I suppose some filters might filter too well and not let the gas run through and cause those symptoms. Alas, since installing the filter I've had no more stuck float. I seem to recall picking my filter up from NAPA or Advance Autoparts for $3 or $4. It's a clear plastic housing with a little brass-looking filter inside. -----Original Message----- From: DSN_KLR650@yahoogroups.com [mailto:DSN_KLR650@yahoogroups.com] On Behalf Of sbartindale has anyone out there put an inline filter on there krl, to try stop shit getting into the carb, if so how did it work out, any fuel starvation probs ?
