      20 to 1 is a rich mixture (even for road racing) and may even be contributing to the speckling your seeing on top of the piston. Think that comes out to 6oz per gallon, go to 4.5 or 5 oz. Running a rich fuel/oil mixture = leaner in the combustion chamber. The popping your hearing is common with a lean condition.

      What effect would creating positive pressure in your air box have on the carbs venturi?

      Thought it was awesome, great seeing some of my pals on tv. Kudoes to Kutcher for pulling it off,  taking karting to the next level. Can’t wait to see the next episode.

      Not sure what chassis your on so your results may vary.

      Take out caster (move top of king pin forward), narrow front end will reduce oversteer on entry but may increase oversteer on exit. Lower front ride height, stiffer axle, softer or remove front bar, tighten rear bumper, if it’s extreme, I would move the seat back.

      Hope this helps.

      Brian, what year is your Crg? In 08 they switched to ven05 brake system, you can’t  put shims in a ven05 caliper. Not familiar with the ven04 or older.

      Freddy, if running the long straight, use a 1.47

      If you run the “kink” try a 5.0 you wont use all of sixth at the end of the straight but it works pretty good in the infield .

      Hope that helps

      “he switched to new bridgestones and it was sliding all over”

      Did he switch to Bridgestone YLC’s?

      If you are going to compare different tire manufacturers,  you have to make sure they are similar compounds. The MG yellows would be comparable to bridgestone YLB’s. Last time I ran a set of YLC’s( prob 4 years ago), I was sliding all over the place, not even close to the mg yellow.

      If you have a soft compound front tire and med compound rears, your going to have a bad over steer.

      And to answer your question, absolutely theirs such a thing as to much grip, especially in the low hp classes.

      “Jimmy, I see you have adopted the ” Best drivers in the World” title”

      Just to be clear, I don’t think for a second that I fall into that category, I was referring to the top guys that flew in from around the world.

      “Jimmy, I see you have adopted the ” Best drivers in the World” title, boy thats been around before. Ever tried a 1/8 mile dirt track?”

      The best drivers in the world comment wasn’t my opinion, its fact. Lennox and Fore are two of the best sprint drivers in the world. Not talking about F1, Road Racing, dirt oval or a bunch of guys racing lawn mowers in their back yard. They are a couple of the best 125 sprint racers in the world.

      Tim, it was past my bed time to. Never in my life have I been on track at 2;30am. I felt like a zombie and the track was fast as heck. I had a steering wheel hub break going into turn 1, was sheer luck that I didn’t crash.

      “We just got back from the Road Race at Blackhawk Farms. 2 mile track 100+ mph for many classes, no shortage of shifters, TaG’s and Sprint opens. Really don’t know official entries numbers but would guess the normal 200-300 entries. Total number of Red Flags, 1,”

      No way you can compare a RR at Blackhawk to a National Protour street circuit race.

      Take the top drivers in the world, put them on a super fast, super narrow street circuit with obstacles and your going to have carnage.

       “I am one that loves a good slide job, rubbing pods mid corner, or even a slick bump and run from a faster driver coming through the field”

      Tim, did you watch the S1 race? Tons of respect. Watching Lennox make his way through the field was amazing. I love racing with the S1 guys, most know how to move a guy out of the way without crashing him, that skill is definitely lacking in other classes.

      Sorry if I offended  you guys.

      When I was club racing, we put 38mm carbs on our icc’s and were slower. To much wheel spin out of the corners. Moto engines are worse, big time bottom end, high comp will add bottom end so will advancing the timing. Im assuming an autocross track is very low grip, prob already a challenge to get it to hook up off the corner.  Also, if you pump up a moto engine, they become very finicky, hard to tune and easy to damage. Ive raced both built moto and stock moto in the same weekend and in a few sessions was faster on the stocker. The built moto had a very small tuning window, if you didn’t hit it rite, it was a turd.

      You can work on your driving in places other than an autocross track. Go to the local sprint track (if you have one) and pound out laps. Learn to drive in a little deeper, be smoother on the wheel, spend time changing the chassis, learning how to take out and add grip etc etc.

      I’ve heard numbers as high as 42hp (debatable) for stock Honda and 48 for the latest and greatest icc’s. A SCCA driver on a 48hp national caliber ICC would get smoked by a top 10 SKUSA driver on a stock Honda any day of the week. I know its fun as heck pumping up an engine with Pi’s, high comp, big carbs etc etc, but the bottom line is, focusing on your driving would prob make you faster than additional hp, especially on an autocross track.

      Jim, my first day ever on the 01 stuff, I was matching my times set on the 99. Buttonwillow was slick that day so it may have favored the 01’s. Honestly I think the 99 is a pretty good cylinder for a gripped up buttonwillow. Always plan on back to backing them on a race weekend but just never have the time.

      I did a back to back session at Tucson last year, wasn’t even close. Don’t remember the exact time difference but I boxed up my 99 cylinder and put it in a cabinet labeled “road racing” lol.

      “I think the timing should be backed down on the 01”

      Prob only good solution if you want to keep the 99 in the game.

      Charles, theirs a reason every S1 driver at the ProTour will be on a 01 cylinder and its not to save money.  The 01’s are faster.

      “For those on the fence whether or not to participate in SKUSA events, having to consider making an investment in a new cylinder (assuming most non-SKUSA participants run 99′s) doesn’t help.”

      I agree 100%, problem is, the damage is done. Close to all Skusa drivers are on the 01 and im sure Skusa doesn’t want to piss off its base. They needed to make a decision over a year ago, if they did it now, people would be very upset. When I invite people to try out a SKUSA event, they don’t want to spend the $$$ to upgrade to the 01 cylinder, and feel they wont be competitive on the 99.

      Higher octane fuel would help the 01’s, it prob wont help the 99’s, if anything it will be a wash or slow them down. Engines run best on the lowest octane fuel you can use without detonation, the 99’s don’t detonate with ms98 so 110 prob wont help performance. IMO 110 octane would be the last nail in the coffin for the 99,s.  Prob not a big deal, 99’s are all but extinct at any SKUSA event.

      If SKUSA’s ok with having an all 01 cylinder series, then I agree, switch to 110 octane.

      Both PWK and PWM are legal in stock moto. The PWM has a little more top end.

      Thanks to everyone for the input. The seller text me a couple days ago and said if the post office didn’t find the parts in the next week, he would refund my money.

      If your chassis has old style brakes, youre going to be at a disadvantage for sure. If the chassis has a 40mm axle, good luck at a National or even a regional (if the regional has heavy hitters).

      Can you be competitive on a 2007 chassis, absolutely.

      Nice job F1. Cars look ridicules, sound ridicules and are (according to the announcer during practice) around 4 seconds a lap slower than last year.

      F1 is suppose to be the pinnacle of motorsports, going “green” is completely stupid. Could you imagine how awesome it would be if they announced the cars would be 1000hp this year. Instead, they did just the opposite.

      Next year they should just turn it into a spec Prius series.

      Would be cool to see the entry lists. I hear some heavy hitters are going to be participating.

      Hi Dan, give Swedetech racing a call. If they don’t have the parts, they can definitely aim you in the rite direction.

      They built a Maxter for me a couple years ago to use at the National finals, It was so dominate, it was almost unfair lol.

      If I remember correctly, that rear piece has 3 screws holding it in, take out the screws and rotate the angled tip the direction you want.
