carb tuning

[ron criswell]

I can tell you what I think of the Gold Wing guy.....ah.....but they usually never wave (heh....except Fred when he is running my credit card). Any of you old KLR guys remember when my front rotor looked like a frisbee? I had been riding in mud, sand....whatever. My caliper froze up and got the rotor hot causing it to warp. This was at about 25,000 miles. I just drained my brake fluid recently on my Concours, KLR......and I thought.....what heck, do the Versys too. I was amazed how dirty it was at just over 10,000 miles. I guess the Gold Wing guy never rides in mud or sand (heh). Neither does my Versys. Radiator drain will be next on the Versys.....the other two are good to go. I don't like buying used bikes because of the habits by other riders. I can't tell you how many brag to me, the have never checked the valves....or had others check the valves. I did the same with my '64 VW.......ah.......should have. Criswell Sent from my iPad

I will work on it.....maybe I should come there in August? I am a big fan of watching people doing stupid stuff. All us KLR guys should ride into Sturgis in a muddy, dirty pack.....with T shirts that read......excuse me rev,.... the Anti Hogs. It could be interesting. We could have mud burnouts with topless muddy women.....ah....jus sayin. A friend has a diesel KLR which is real.....ugly. He could come. 90 degrees here today enjoying a beer after finishing a valve check on my Concours, new plugs, air cleaner cleaned, oil change and new front tire. I think I will get in the pool shortly. Criswell Sent from my iPad

I have seen some bikes with lots of miles that have never had fluids changed and they look good. I have also seen new bikes with low miles and the fluids were needing to be changed. So the moral to this story is that you may or may not need to change fluids often but you better be checking them on a regular basis.

The funny thing on my Versys, it looked fine in the window.....but didn't coming out. Looked clear but came out dirty. Criswell Sent from my iPad

Lee: Back tracked to find my source: Msg #48 http://www.advrider.com/forums/showpost.php?p=20860987&postcount=47 Moving the clip changes the fuel mix by a factor of 5-8%. So maybe in Mikuni terms that's a skosh over two sizes, rules of thumb aren't truly precise and VM jets aren't available in 2.5 increments, only in 5s. Still every move he makes is 8% of 190 at the baseline. 8% of 190 is slightly over 15 and that's three jet sizes. Or it could be 5% and thats 9.5 so it's two jet sizes. Damn rule of thumb variance. It is true that the main jet determines max fuel flow at WOT but it also determines the baseline that the needle begins with, nothing can change that fact. Then the taper and clip height come into play. Bottom line, all of the circuits in a Mikuni interact except the "enrichner" which is a totally independent circuit. Ref: chart 13 page 9 Mikuni tuning manual Checked against said manual to verify (http://www.mikuni.com/pdf/vmmanual.pdf) page 9/fig 13. Makes sense to me. If you were to tune the mid throttle (needle in mid slot) by changing the needle jet, then from there on you should only have to adjust the needle for most situations, but I ll let you crunch the numbers.

If one had access to the actual numerical dimensions or the Needle jet itself and the needles with dimensions and taper defined one could run the numbers to determine the specific annular areas and answer the question. In lieu of that work there is the Mikuni Engineering Dept where that info is readily available. In the '70's when we were doing a lot of substituting Mikuni's for Amals or the German carbs I was given a complete catalog of Mikuni carbs and tuning details-40-50 pages, I'm not sure if I can find it now. I do have a very good filing system . . .it's the retrieval system that sucks. Let's start asking questions through all of our potential sources and see if some one of us gets a "Bingo Moment", then please post it.
