I was thinking of dropping my needles to 2.5 to clean up the bottom and mid has anyone else tried it ?
Thanks
 

Instead of dropping the needles, add the remote fuel screw adjusters. The stock fuel scew setting is very rich and makes the sled run like a pig in warmer temps. In the mean time you could set the fuel screws to 7/8 turn each. That will help out alot. The adjusters that Bender sells work very well.
 
Don't set them on 2,5, it caused the dcs on my 2002 blink constantly when "on the needles".
 
I don't know your elevation, but if anything the 2000's were lean in the midrange on a long pull.
 
i dropped the needles to 2.5 but that was on my 98 but i have no problems with it at all. if you know how to read plugs fairly well you can drop it to 2.5 and do a few runs then read your plugs and see how they are if it's too lean or not. dropping half a clip is not a huge change so as long as you don't run it in the midrange for miles you won't blow your motor. just run it long enough to do a plug reading about half a kilometer then shut her down and check. you can adjust the needles while the carbs are still on but if you've never done it before it can be a pain in the ***. if you have time and feel like it i would even suggest taking them off the first time you do it lets you see a bit better and closer to see what's going on in there. but if you're gonna leave them on then definately put a nice clean rag under the carbs to catch anything you might drop and you probably will drop something lol believe me. good luck
 
Thanks rules, I've done them before on my SX I was just wondering if it would clean up the low and mid range like it did on the SX700. It seems to me that the SRX is a little more tempermental at mid and high end. Thanks.
 
Im heading out to Ron's in moose creek sat about 8 am and hes going to let me change the jets in his shop.
 
I'm tellin ya it's the fuel screw adjustment. It controls that area (low to mid) that your complaining about. The stock needle setting and the stock jetting is just right on that sled. The stock fuel screw setting is a good half turn too much. The carbs need to come off to adjust them and thats why you need the remote adjusters.

Are you trying to get rid of that "misfire" by changing the carb setup?

I wanted to make sure and put the carbs back to stock. The engine is much crisper now. But The mis happened just a couple of times today when it was hot.
77-SRX this mis happens at almost full throttle.Its just a couple of baw baws.
Now you think its the air screws,but don't the only control idle and part throttle???
Thanks
 
No, the fuel screws take care of the low to mid area as do the needles. It's not an idle air adjustment. If you doing alot of trail riding in warmer weather you may be loading up the plugs a bit. If yours are still at the stock setting of 1 1/8 turns open it will start running crappy at around 20-25 deg f. Thats what I found with mine. I do know that alot of dealers would lean out that setting before they went out the door new. At the very least they should be set at 7/8.
 
So no idea for my top end misfire that occasionally occurs.
It almost sounds like bapbap than goes away.
I think Ill set the fuel screws at 7/8's out and see if that doesn't lean it out and not load up the plugs and further cause that mis.
