Dinojet kit and white spacer.
08/07/06 at 05:24:51

Need some input to verify my thoughts or set me straight. With the Dinojet kit a new needle with I think 6 grooves is installed instead of the stock needle. The kit says install the positioning clip in the 4th groove from the top. With this setting the bike runs much better than stock, but the mid-range seems a little flat. Doesn't bog or anything, just doesn't pull as strong as I think it could. My question is, by lowering the clip to the next groove am I in effect doing the same thing as thinning the spacer and do you think I'm on the right track? Any in-put appreciated. ???

Reply #2 - 08/07/06 at 16:33:33 Did you keep the white spacer when installing the Dynojet kit ? I have read on here that you need to keep the whole white spacer in. Lower needle - leaner Raise needle - richer Lowering the clip raises the needle. Raising the clip lowers the needle.

Reply #4 - 08/08/06 at 05:14:39 Yes, all spacers were reinstalled as instructed. I'm thinking I need to go a tad richer to improve mid-range response. Any thoughts? Full throttle is excellent and plug looks good when checked after hard high speed run. Just seems a little flat in mid range.

Reply #5 - 08/08/06 at 17:11:59 My Savage pulls very hard in the midrange Yes, raise the needle. Sometimes it's hard to tell if it's rich or lean (unless you look at the plug), but going richer is always a safe bet. If it runs worse, you know you were rich and not lean.

carb theroy 101 not sure if its this site or not tech section.. on thing ive noticed tho most carb postings are from(dont get offended) low landners,down streamers,
one MUST take altitude(and for sluggos sake attitude)
into consideration.. not to mention humidity,BM pressure
grade of fuel,twistness of the right wrist etc etc...
the most one can hope for is(nervona)a happy medium when carb tuning..she'll run one way at 2 am and another at 2 pm thats the nature of the beast.. 8)

And that's why you use the tuning process instead of, for instance, just the same number of turns as someone else. If your operating climate changes significantly, tweak it. I'd bet you'll be able to find a set of jets that works in most, if not all, of your riding conditions. Then it's usually just a matter of having a small screwdriver with you. My point is that it's the tuning process that can be carried from bike to bike and from locale to locale - not the turn count or jet size. Below is a quote from Lancer and it pretty well sums it up.

Quote:

-start with the pilot adjusting screw at 1.5 turns out as a reference point, and count as you turn in and out so you always know where you are during the process. Everything is done and referenced in the "# of turns out".
-turn idle up a little so you have a smooth fast idle
-turn pilot adjusting screw "in" until engine begins to slow downand note the # of turns out
-turn pilot adjusting screw "out" until engine begins to slow (it will speed up initially then go down) and note the # of turns out
-then set the pilot adjusting screw in the "Happy middle" of those two positions
-after the pilot circuit is happy, turn the idle adjusting screw back down for the idle you desire.

*for ex...if the turn in setting was at 1 turn out, and the turn out settig was 3 turns out, then the happy middle is 2 turns out.
**Turn slowly as you do this, no more than 1/8 or 1/4 turn at a time...then pause and wait 5 seconds or so in order to give the engine time to adjust, then turn again if necessary. If you have a tach, then you can set the pilot adjusting screw by just tuning for max rpm, then set idle speed.
***If after you have finished this process, the pilot adjusting screw is 2.5 -3 turns out, then you definitely need the next larger pilot jet. For myself, if I go over 2 turns out then I go up to the next size pilot jet.

When the pilot is properly adjusted, and assuming there are no exhaust leaks in the system, you will not have any backfiring. It is normal to have some mild crackling and popping on brisk-hard deceleration, but there will not be any backfiring.

Good points. Besides differences in temperature and altitude which affect jetting, keep in mind that every bike and every carb are different. Recommendations here and elsewhere are just the starting point. Dynojet's recommended settings must work in the majority of bikes that have their jet kit installed in. This covers alot of locales, altitudes, and temperatures. Their settings won't work in all cases.

Thanks to all for your thoughts. I completely agree that what works best on one engine in a given area may not perform well at all on a different, otherwise identical machine in a different part of the country. Likewise, the comments on temperature, humidity, etc. were dead on. I've found that an engine running slightly rich will perform best on cool days, while one that may be lean runs best when it's warmer. (air density and all that) I'm going to try raising the needle in mine and see if it may improve my midrange a little. If not I'll try going the other way . Like many of you said, that's what tuning is about. Thanks again.
