    EKN needle results....not so good !

    You are exactly correct, go one clip richer on the needle. See my setting below for comparison.

    What happened to the re-sale value??

    I am not a resale expert, but I would say it has something to do with that new bike called the CRF450.

    Cut down length of muffler?

    I am thinking about cutting about 4-5 inches off the back side of the stock muffler. Has anybody done this? Other than making it louder, are there any other effects. Thanks

    I'm getting weary

    Taffy, I had the opportunity to run a race with a long paved straight-away. With stock gearing, the bike pulled redline with absolutley no problem. It actually felt like it could have have pulled much higher gearing as well. Because top speed was reached very quickly. I knew things were working well, because I was closing on YZ426's by about what seemed like about 5-8mph (just a guess), but a pretty decent closing speed anyway. So as for the upper end not working, or being wrong on my bike I have to disagree. Maybe with a free flowing exhaust at see level, larger MAJ's and MJ's work better together than with your settings of quieter exhaust and altitude? What does top speed in top gear on pavement work out to anyway? Maybe about 90mph?

    Sounds about right to me. Go with a EKN#4 if no bk mod. Although some people might find this rich. You are on the right track for an initial set up. Also limit the fuel screw to 1 turn.

    BK mod - this time in metric

    The GP was great, cool and overcast most the day. I felt like I finally am getting faster. Standing up through a lot more stuff and rarely sitting down. Next time you go riding let me know. We can swap bikes. It would be fun and interesting. ------------------ 2000WR - EKN#5, 175MJ, 226MAJ, MAJ Passage drilled to 278, 48PJ, 100PAJ, YZ timing, BK mod, 3/4 turn pilot screw, DSP tapered header and pipe, IMS tank & YZ seat, Scotts dampener & triple clamp & Renthal Fatbar 971, White Bros suspension, Dunlop 756's.

    Ron, I just read your post in "Jetting Party" results. You really got a EMN#4 (EKN#3) to work? This does surprise me, as we have nearly identical set ups. I was screwing around yesterday to try to get a EKN#4.5 (EMN#5.5) to work. I just wasn't happy with the throttle response, it still had a slight tendency to die when given quick throotle openings right off idle. I even tried backing the Squirt out to 2 seconds, and backed the screw out to two full turns, and still not happy with the results. As for the 175, I like this better. I raced Carlsbad today, and there is that big straight away. So I had the chance to really test it. No drop off when it comes on the main like with the 172. As for the EKN#5 (EMN#6). I was digging this needle setting. There is a large hill that has quite a few bumps going up. I had a hard time keeping the front end down, the bike has tons of torque on the needle. Wheelies are extreeeemely easy now. I wonder why you haven't got similar results? ------------------ 2000WR - EKN#5, 172MJ, 226MAJ, MAJ Passage drilled to 278, 48PJ, 100PAJ, YZ timing, BK mod, 3/4 turn pilot screw, DSP tapered header and pipe, IMS tank & YZ seat, Scotts dampener & triple clamp & Renthal Fatbar 971, White Bros suspension, Dunlop 756's.

    HELP!!California Green Sticker questions

    Sirhk & Kris I have done the same thing, but the more I ride in different areas, the more I am realizing that doesn't really matter. Rangers just don't seem to care Spark Arrestor - Tres Importante. Green / Red sticker - who cares. So even after going through the DMV song & dance to get a Green sticker on my son's 2000 YZ80, I feel that I may have wasted my time and energy unnecessarily. ------------------ 2000WR - EKN#5, 172MJ, 226MAJ, MAJ Passage drilled to 278, 48PJ, 100PAJ, YZ timing, BK mod, 3/4 turn pilot screw, DSP tapered header and pipe, IMS tank & YZ seat, Scotts dampener & triple clamp & Renthal Fatbar 971, White Bros suspension, Dunlop 756's.

    Harold, No I don't think that the EKN#5 is too rich, in fact it is probably just about perfect for sea level. However, I can say is that it is too rich at 8,000ft. I have yet to see if it is too rich at 5,000ft. As for one-half clip adjustments. Do the following, get a very small washer (I just picked up a #3 washers at Lowe's) and put it under the c-clip to raise the needle 1/2 a notch. The washer should be the thickness of the groove (in the needle) or the thickness of the distance between grooves, I think both are about equal. This will give your fine tuning ability. On the #3 washer I used I did have to open up the hole a little with a dremel tool as the needle was a little too big to fit through. ------------------ 2000WR - EKN#5, 172MJ, 226MAJ, MAJ Passage drilled to 278, 48PJ, 100PAJ, YZ timing, BK mod, 3/4 turn pilot screw, DSP tapered header and pipe, IMS tank & YZ seat, Scotts dampener & triple clamp & Renthal Fatbar 971, White Bros suspension, Dunlop 756's.

    Ron - Thanks for the thought. When you talk about timing you are talking about the screw that is on the other side of the new BK screw. Correct? If so I haven't messed around with this because it seemed like the squirt was exactly where it should be, immediately, but not into the throttle slide. Harold - when you do the mod, go one clip richer on the needle at the same time. As for the benefit. I feel like you do. Why fix what isn't broken. I felt like my bike worked so well before the mod that it was an unnecessary improvement. But "In Thumpertalk I trust" So I thought I would give it a try. And there are benefits, so I will spell them out. The bottom line with the accelerator pump squirt is that it last about 3 whole seconds. This is long time. This creates two problems. 1) With the squirt at 3 seconds this requires a leaner needle setting, so that after the squirt is gone the needle feels a little leans. In other words the squirt masks the correct setting. I only really noticed this on my bike in a long uphill climb at Glen Helen during the SRA GP when the track gets routed up a longer hill than normal. The bike had power starting at the bottom of the hill.. Then 1... 2... 3... , "hey why is the power dropping off". (no more squirt!). The bike now feels meatier in the mid. With the EKN#5. 2) The second area of improvement is the uncontrollability of having gas dumped into the carb. Previously the bike seemed kind of twichy to throttle changes at slow speeds. Either in tight trail riding or when I would get tired towards the end of a moto and hit braking bumps, the bike would feel a little like a bucking bronco. Nothing teribble, and yes it is mostly my fault anyway for being a spaz. BUT THIS IS THE MOST IMPORTANT REASON TO DO THE MOD, in my opinion. More controllable throttle response off idle. Now the bike feels softer or more manageable at small thottle changes during low speed operation, WITHOUT a sacrafice in POWER or SNAP. When I want power it is still there, but now I only get it when I want it, not when I unintentionally twitch the throttle. Hope that helps.

    James thanks for your comments, they kind of confirm that an EKN#4.5 might be the optimal setting for 0- 5000ft in altitude. I am going to run a race this weekend at sea level with the EKN#5 / 175MJ, and then maybe try to dial in the EKN#4.5 by increasing the squirt until snap comes back. It is surprising that just a .5 clip adjustment makes a significant difference with regards to throttle response. ------------------ 2000WR - EKN#5, 172MJ, 226MAJ, MAJ Passage drilled to 278, 48PJ, 100PAJ, YZ timing, BK mod, 3/4 turn pilot screw, DSP tapered header and pipe, IMS tank & YZ seat, Scotts dampener & triple clamp & Renthal Fatbar 971, White Bros suspension, Dunlop 756's.

    HELP(plugs)HELP(plugs)HELP(plugs)?????

    Never had a fouled plug in about 3,000 miles. But last time I washed the bike, I didn't start the engine up afterwards. Next week was the bike didn't start, for the first time ever. So I changed the plug and it started right up. Just a thought. ------------------ 2000WR - EKN#5, 172MJ, 226MAJ, MAJ Passage drilled to 278, 48PJ, 100PAJ, YZ timing, BK mod, 3/4 turn pilot screw, DSP tapered header and pipe, IMS tank & YZ seat, Scotts dampener & triple clamp & Renthal Fatbar 971, White Bros suspension, Dunlop 756's.

    Ron, This is very cool to have your thoughts confirmed. This definetly helps to have a second opinion. As for possibly being able to take a larger main. This is probably been the only change that I am making that is outside of James Dean's recommendations. James has been scarily accurate. When I have tried james's recommended settings for my bike they were perfect first time out. As for our DSP exhausts needing larger exhausts, who knows? It sure is one large, meaty pipe running through the frame rails. And maybe the tapered header helps exhaust the gases as well? The other possibility is that I have drilled out my MAJ and MAJ passageway, so maybe I can take a larger MJ. But here is what I am thinking. The bike ran great at 8,000 ft when on the 172 main. I could feel the bike load up on the needle EKN#5 = EMN#6 and then when it came on the 172 main, nirvana, so how can a 175 not be better at sea level? This weekend I am going to race the SRA GP at Carlsbad. 30+ beginner class. All right I am not the fastest guy. So for this weekend I will atleast keep the EKN#5=EMN#6 , 175MJ settings. But if when I go up to silverwood/ arrowhead 4,000-5,000 the EKN#5=EMN#6 setting is still too rich, then I am going to go to an EKN#4.5 and increase the accelerator pump. After the BK mod (w/.3 sec squirt)this is what I noticed about the needle settings. EKN#4=EMN#5 - Bike flat just dies off of idle. EKN#4.5=EMN#5.5 - It is pretty hard to stall it gasing it right off of idle, but still possible. (maybe curable with more squirt). EKN#5 = EMN#6 - Throttle snap problem of idle solved. But maybe too rich at 8,000ft. Being lazy by nature. I want to get a setting that is perfect 0-,6000 ft, so I don't have to do any jetting changes. Thanks for you input as well. ------------------ 2000WR - EKN#5, 172MJ, 226MAJ, MAJ Passage drilled to 278, 48PJ, 100PAJ, YZ timing, BK mod, 3/4 turn pilot screw, DSP tapered header and pipe, IMS tank & YZ seat, Scotts dampener & triple clamp & Renthal Fatbar 971, White Bros suspension, Dunlop 756's.
