sk6f3 Posted February 20, 2005 Share Posted February 20, 2005 I pulled out the two washers I had added to each stock needle. Opened my slide hole from 7/64 to 1/8. I left my idle jet at one over over stock at 45. New plugs, new oil and clean K&N filter. What a difference! It was about 34 this afternoon for my test ride. As I rode easy initially, I noticed the temp guage was riding a little higher, was I so rich last year that the extra fuel was keeping the heads cool? As I opened the throttle in first from low RPM, no flat spots, and I got the usual power wheelie at 7K, but as I kept it pinned the front was rising way faster than before the rejet. I dropped front tire back to earth, hit second and nailed it again. I am forward, with no clutch and the front is lifting again! My bike did not power wheelie in second so easily before. Of course I had to test this again and again. No doubt, the bike is pulling harder everywhere. Fun afternoon, great to make a change and have it work well. Thanks for the ideas.

Byrdman Posted February 20, 2005 Share Posted February 20, 2005 Keep us informed as to the fuel mileage you get witht he new changes. Quote Link to comment Share on other sites More sharing options...
51'er Posted February 20, 2005 Share Posted February 20, 2005 Sounds good. Keep in mind it was 34 degrees. That's a big part of your new found power. When it's below fiddy degrees I literally have a hard time keeping the front on the ground. Quote Link to comment Share on other sites More sharing options...
Pete in PA Posted February 20, 2005 Share Posted February 20, 2005 You know there is a stock washer on the needle right? So you had a total of 3 washers on each needle initially? You'll probably get better mileage now. That's a lot of lift. Do you have a pipe or stock exaust? I just got a Gerbings electric jacket liner and was out yesterday and am still amazed at the power I gained with the slide hole drilling. Going out today, probably the last time for awhile, snows coming. :cry: I'll fill up today also and get another tank in to get my MPG. I don't think I lost much if any. Oh, and you are welcome. :wink: Quote Link to comment Share on other sites More sharing options...
sk6f3 Posted February 20, 2005 Author Share Posted February 20, 2005 I did retain the stock washer on the needle. Rode the bike all last season with three total washers. I had no flat spots but I think it was too rich. Plugs with 8K were not light brown, more of a dark and damp look. I have the stock header with Staintunes and the outlet baffle installed (too loud for me without it). I have a 17t front and 47 tooth rear. Best milage I could get riding easy and near the speed limit was ~34, and only 30 or less, if riding agressively. For seat of the pants power comparisons, I've been out several times this winter. Clear, dry and 10 was the coldest day. I could feel the extra punch from the low temp, but the increased power with the jetting changes is much greater. I wonder which change is having the greatest effect, increasing the slide hole, or leaning the needle? I have to order new tires. I ended up liking the performance of my pilot roads, but I have a little less than 3K and the rear is almost done with the front not far behind. I always ran between a range of 39-42 in both the front and rear. Two sets of Diablos before these were even worse. I plan on trying Avons this time. It will be a while before I can report back on milage, everything is white again, we are looking at 3-6 inches of snow today. Quote Link to comment Share on other sites More sharing options...
Pete in PA Posted February 20, 2005 Share Posted February 20, 2005 Just got back, put 210 miles on the tank and put in 5.1 gallons for right at 40 MPG. :grin: Now I love the carb. slide mod even more! Glad I found someone else who can burn through a rear in 3K miles. Esp. a Pilot Road. That'll be it for me also for awhile till this snow goes. :cry: Quote Link to comment Share on other sites More sharing options...
