I see a good bit of talk about re-jetting of the carb in this thread, and it seems many of you here have a super understanding of this carb. I have a question regarding my 1995 800A, I purchased last year. Here’s what I’ve done so far. (Thanks to many of the posts in this site). I have removed the rear baffles in the stock exhaust, added a K&N filter, drilled out the A/F plug and have the idle air screw currently backed out to 2 7/8 turns. It now starts and idles very well, even in the cold air of Erie PA in April. I changed the sprocket setup to 18/40 and with that, gas mileage is up from 43 to 52.6 on the open road if I’m easy on it. All in all it runs very well and smooth. There is no de-acceleration pop with the throttle closed, but an occasional pop when “crackin’” the throttle to downshift. I can feel it come back through the carburetor and air filter. This is a rare occasion happening maybe once for every 20 downshifts. It does seem to occur more when hot. (Outside air temp 85 and higher) I found running the 87 octane fuel shows no appreciable difference than the 91-premium stuff, so I use the 87. Plugs look great every time I’ve had them out. I also run 2 ounces of seafoam every 5th tank just to keep things clean.

My question is the top end of the throttle does not seem to provide much acceleration. ½ throttle and down is brisk and smooth, but wide open does not provide any more power than ½ throttle does. Engine sound and performance simply does not change in the upper throttle range. Could this be a jetting issue??? Or is something else to blame. (Maybe the sprocket change??) All in all, the bike is a very solid runner and I am on that line of do I fix something that isn’t broke??? (Unless it’s broke) I do not use full throttle often, but when I do, I’d like to feel it. Somethin’ about WOT that just gets the blood pumping!!!

Thanks to Beartooth Kawasaki for a great forum!!!

Ride hard, ride safe and ride often!!!!
