First I drilled off the air pilot screw plug (one thick mother) and backed it 2 1/2 turns from the seated position. I put a 1mm washer on the needle so it stayed backed out of the main jet nozzle just a bit. I put it all back together again (after stripping the pilot jet - how the hell do you get that thing out of there? and tearing the float seat o-ring - dammit!) I was amazed that the bike started after such a nasty assault. I rode down the street and did a wheelie (my version of a wheelie) in 1st but couldn't do one in 2nd. I figured this was the best way to test the new awesome results of my carb mods but the bike failed the test. However, this simple adjustment did give me quicker throttle response and the bike doesn't seem to run so lean anymore (my expert opinion). I'll be interested to see if the Thumper racing JX needle does anything more. I wonder if Thumper is just selling parts from another carb like the DR350 dirt version. Anyway - I guess things went OK with my mod and the washer on the needle thing seems to work well.

Are you pulling Ginos leg because the only exercise it gets is when he walks back into the house for his second cup of coffee after pushing his magic button?? I personally enjoy my kick start DR for several reasons. On cold Michigan mornings kicking the thing to life is an opportunity to warm up before blasting down the trails. Secondly, if the bike is tempermental about starting (a rare occurence) , it inspires me to ride cleaner at the start of a loop as I know I won't have the energy to pick the bike up if I go down. Crashing early would require that I wait for my riding partners to catch up to help. On several ocasions they have miss interpeted me laying under the bike. I do this to let them know I need asistence. They think its my way of letting them pass without hurting their youngblooded ring-a-ding egos. Usually the smell of 2-stroke oil as they roost past is enough to rejuvinate me. I have no trouble restarting when there is fire in my eyes. Sorry, too much coffee this morning and the wife has a silly rule about starting work in the garage before sunrise. I sign off as the sun peeks over the eastern horizion. Its supposed to be 60 and sunny in Detroit today after a week of rain.

Let's just say I bounced off of it, but I didn't go down. If I don't go down, then I figure I win :-) The only guy I know that knocked over a tree was Merf. And it sounds like the tree got revenge because when it came down, it landed on him and flattened him pretty good (he did eventually get up). - -- Scott Aldrich / UN*X System Administrator ------------------------------ Date: Sat, 24 Apr 1999 15:28:05 -0500 From: charles w vokac Subject: [none] I just went riding this morning to try out my new carb mods. To recap, I put a 1mm washer on the needle of my 92dr350s and have cut holes in the top of the airbox. I have a stock muffler, airbox, filter - I have a 135 main jet, stock pilot jet and 2 1/2 turns from seated position for the air pilot screw. I haven't installed the JX needle/ spring yet. The results are as follows: There is definitely more responsiveness in mid range. On the trails, there was a noticeable improvement in 1st through 4th gear all the way through to wide open throttle. I had to watch myself because the bike lurched forward a little in 1st and 2nd because of what seemed like an increase in power compared to what I am used to. The bike also seemed to run a little quieter but that might be my imagination. Wide open in 6th on the road to the trails wasn't changed noticeably - neither was top end speed or rpms at top speed. The bike idled and coasted fine. It doesn't seem to be running lean anymore. I am very pleased! I don't think I will use a bigger main jet for fear of causing the bike to run too rich.

I know you guys cant wait to know how I'm coming along with my carb, so here it is: I'd put in a Thumper JX needle & spring, a 130 main (stock 127.5), and a 40 pilot (stock 37.5). Ran great at mid & high rpm, but was rough at idle....too rich. Put the stock pilot back in, drilled out the brass plug, backed out the pilot adj (fuel mix?) screw 1 full turn, put it back together & it ran great everywhere & iddled smooth. Good throttle response. A few of you had warned me that I may have screwed up the float level when I had it apart, but I guess I didnt. With all that being said, I just got back from the MX playground, doing about 30 min of small jumps, woops, etc. After 30 minutes, bike started running really rough. Got back on the hiway heading home, & it smoothed out at full throttle & eventualy ran well again. Right by my house there is a 45 degree long high dirt hill that I rode up & down about 5 times, & sure enough, the bogging/cutting out started again. Went away on my way home after some full throttle street time. When I looked at it in my garage, there was some gas dripping off of my idle adjustment screw, & gas was all around the bowl. I dont know what the deal is....after I wiped it off, it wasnt still coming out...no leaks or anything. I guess the hill made it happen. Whats going on here? Are these carbs on the SE's not tough enough to do the wild stuff in the dirt (not that what I was doing was wild)? Are the dirt only carbs not CV? Does that make them alot better?

Forgot to mention in my last carb update post.. I ran about 50 miles between recent carb tear-downs. Time before, I completely cleaned the bowl, float, everything. There was alot of fine black powder all in there. This morning when I tore it up,,,er, open, the black powder crap was back! This is the deteriorating cheap lousy fuel line that Suz put on!! I put it back together w/ some neat looking super thick transparent blue LeMans urethane fuel line, and stuck a high-flow steel screen filter in line for good measure. Next time I tear it open, I bet I dont see the black powder crap. Bryan in Dallas 95 DR350SE _______________________________________________________________ Get Free Email and Do More On The Web.
