sprockets - was drilling the carb slide

[Luke in Brooklyn]

As a matter of fact it makes so much torque it rips the knobs right off the tires. Also it is not very hard to "drill it smaller" if you know how. Oh yeah? Well MY bike can tear chunks out of those steel road plates from a stop... in THIRD GEAR! And it has a supercharged turbo-booster from dualstar! Sorry, that post just made me smile. My constructive contribution is: If you wish you hadn't drilled it out so big, you can simply put a dab of JB Weld or even a gasoline friendly sealant in the hole, then redrill it. It isn't squirting fluid/gas/mix like most carb orifices, just passing pressure, so this works fine (at least according to list banter of the last few years).

Lash: I've been running the stock 15T with a JT 44T rear with the stock 108 link chain for the last 7000 miles. I've run it this way on serveral +/- 1000 mile road trips and 100 mile / day dirt road trips (always traveling less than 35 mph). I still get 55-57 mpg (according to the famous 10% error KLR speedo/ odo) and my "sweet-spot" is around 4300-4500 rpms for a 60 mph (GPS verified) result. This gearing is a good all-around ratio and really not that much different from stock (obviously). Once I need to replace the stock chain, I want to change the rear to a 45T (wish a 46T was more commonly available) and carry a bag with a 14T, 15T, 16T + a prevailing torque nut so I can better match the bike to the "long term" riding situation. I now think that I (you) could have gone with a 14T-15T front / 45T rear and continue to use the stock chain since, in my case, 50% of the chain adjustment range is still avaiable. Don R100, A6F

His reasoning made sense to me: If you go a smaller counter sprocket, you are bending the chain into a tighter loop there and putting the same power into one fewer links. Obviously, this would increase the strain and wear. With a larger rear sprocket that is not so. > > Of course, if you want to ride the freeway to a location, then do a quck change along the road, it would be more practical to change the countershaft sprocket. *Duhh!* However, if you do most of your riding at slower speeds, and you stay at the lower sprocket gearing, his point makes good sense to me. > > For me, moving in the opposite direction is indicated because I do almost all my riding at highway speeds, or at least very fast dirt roads. (usually 40+ MPH.) Therefor, a higher gearing makes sense. When my original chain and sprockets are shot I could try to find a 44 tooth rear sprocket which is almost a perfect match for going up one tooth on the counter sprocket. I would expect that I would need a chain which is a link or two shorter, but maybe not. Why not go up one on the counter sprocket to get more links into the action instead? I may, but first I need to look at clearance issues. This is my first KLR and I'm not sure how much room there is down there and some bikes I've had over the years was a little too close for that. If there is plenty of room, I may very well do it that way. I suspect it will be fine since many of you have been doing it that way for a long time. > > Lash > > > > > ----- Original Message ---- > From: GMac999 > To: Luc Legrain > Cc: DSN_klr650@yahoogroups.com > Sent: Sunday, February 24, 2008 8:13:46 PM > Subject: RE: [DSN_KLR650] KLR650 : Drilling the carb slide > > Luc, > > I think it's the opposite.

3.175mm .125" 1/8" 3.2639mm .1285" #30 According to the Drill bit chart sizes I use at times, a 1/8 is actually just a hair bigger than a #30. http://bobmay.astronomy.net/misc/drillchart.htm Good information there.
