I think Shark Shifter Carries them as well as the Hegar.

Don’t mess with an F1 drivers girl friend then LOL. Just messing around have no idea what happened over the weekend.

[David McDowell]

This is the place for all non four cycle stuff.

 

bob’s four cycle is good if you run any 4-stroke classes.

[David McDowell]

I heard in the rumor mill that John at Fast-tech was working on a stock 80 cylinder head and piston package to bring the class back together, since from what I heard the whole 80 class was killed by the programmable ignition and heavy modifications.

So maybe he was going to source the cylinders and pistons and only sell similar units so that the class would be even.

[David McDowell]

Daniel,

 

I think it is still in the making like the title says. If you look at google earth this pavement was not even there this time last year.

[David McDowell]

I get the wife’s crochet needle.

[David McDowell]

To me it seems like the IKF just needs to fade into being an insurance company so that interdependent rented tracks can continue to operate.

The other option would be to take on the 4 cycle part of the industry to a national level. If you think about it SKUSA is for shifters , ProTour is for TAG’s  , and Rotax is Rotax but all pull the other classes in so why not have one focused on 4 cycle.

Bruce,

 

We switched to Hoosiers this year and have found that they are very inconstant over their life and heat cycles and that it is hard to get more than one day out of them. This is for 125 Stock Moto.

My question is what are you class are you racing and around what tire pressures are you running? We have tried everything from 10-10 to 13-15. With limited results.

 

Thanks,

DJM

I am a little lost. Besides price what is the difference between this GPS and the GPS you can get from Mycron? The only thing I see is that your unit does not have a lateral or longitudinal accelerometors  and is less expensive.

[David McDowell]

Our club and most clubs associated with IKF should be running the R60 this year, since it is the spec tire of the series.

[David McDowell]

Picture number one is the front left and picture number two is the front right. Our track is perdominatly right hand turns which should stress the left tire more I think. Camber and Toe are exactly the same side to side. The front right is scales 2 lbs heavier than the left as well. I am lost as to the cause of this. Any help would be appreciated. I will also try the comments above at the next outing.

[David McDowell]

Freddy,

 

Thank you for that input it makes since, I have been fighting the same problem during my first three races. I thought it was being caused by the change in tires since it did not happen at all last year, but is happening now that we switched tires. I will look at the play in my spendles and change the kin pen since I have a few extras.

 

 

[David McDowell]

Andrew do as you would like. I’m just going off the information my engine builder gave me. I respect his opinion since he works directly with Briggs and has dozen of national championships with the motors.

[David McDowell]

You need to be very careful about the oil. Stick with they same synthetic compound that has always been ran in the motor. I have one motor which I run Cool Power in and another which I rung the Briggs 4T since these were the oils that the builder started with when I purchased the motors.

Pump gas works perfectly with these motors if you can find 83-87 octane that is ethanol free that would be the best.

 

Have fun. But I assume after a few track days you will be itching to start pack racing.

[David McDowell]

Jeff,

I was thinking the same thing regarding the set up, driving style , and tire pressure. The other competitor was going off on how the two tires appeared to have different compounds. So I figured I would ask the questions and see if anyone else had experienced any problems. I know that they were running 12 front and 13 rear while I was running 13.5 front and 15.5 rear for pressures.

 

Thanks,

David

[David McDowell]

TJ,

Thanks for the input.

[David McDowell]

Josh,

 

You are looking at rim width not circumference. Most rear wheels ran today are 5″ circumference.

[David McDowell]

Bill,

 

AIM makes the SmartyCam to link with the Michron to allow just this thing. See link below. http://www.aim-sportline.com/eng/products-car/smartycam-hd/

[David McDowell]

Chris,

To me if you put bumpers on the karts the just become rental karts with big engines. I don’t know when the first race you watched was but since 2010 most organizations have required full width rear bumpers since the largest cause of flips was due to wheel to wheel contact, when the wheels are rotating in opposite directions.

I have never seen a kart flip from side to side wheel contact, and have been behind many in races doing this the whole way down the front stretch.

 

The bold move to pass is the whole fun of racing. It’s who has the balls to push the breaking zone that extra yard or two to get the pass. Or who is the chicken and will give the inch to allow room.

[David McDowell]

Kevin,

If you want to race 125’s come up to Medford we should have a pretty decent class next year. If you would like some good shifter racing get a 80 and come race with us next year.

 

With that said, I would recommend starting with a less powerful kart and get some seat time.  Even with the track time you have with car’s, a shifter kart is a completely different animal. This year we had 6 guys move into shifter from tag and wf, and for all of us it was a huge jump in driving and speed. It took us all three or four races until we finally got up to speed and got some good racing.

 

As for chassis I would take the advice of the two above and look for a newer kart. I got my 80 kart put together by purchasing a 2010 CRG roller chassis for $1400, and a old Emmick chassis with new motor on it for $900. So you can get into a shifter on your budget you just have to be creative and smart with your decisions.

 

Good luck and hope to see you at the track.

Don’t just run around by yourself, the thrill of the pack is much greater.

[David McDowell]

Chris,

 

I’m not an expert tuner but I would say hopping in the corner you mentioned is due to over driving/driver error and not the kart set up. I would also loose the rear bar if not all bars.

[David McDowell]

No, No, and No.

 

Stick with the standard shifter set up.  I ran the paddles for half a season, then made the switch. Boy do I wish I would of changed before the season even started.

The problem is the amount of time and strength it takes to shift a gear is far greater than the standard shifter. I would say you can downshift threw 3 gears with the standard shifter in the same amount of time as one with paddles IMO.

[David McDowell]

Capo,

I have driven many different tracks and the so cal track is just as good as any of them. You are to focused on its location and forgetting the fact that it is a purpose built sprint track that gets used everyday of the week. It is not assembled and disassembled after each event. There is also and advantage with it being all asphalt in that you do not have to deal with mowing the lawn and damaging your chassis when you go off track.

 

You will be looking for ever if you want to club race and consistently have 15 racers in your class.  In our club with out non-members showing up our numbers vary anywhere between 4 and 18, just depends on the weekend.

[David McDowell]

Dave, They are contained in the standard IKF rule book. As far as I know you do not need a special book for shifter karts. You can order the rule book right from their web site.

Also on our track the last few races it has been really slick with minimal rubber to start the day. So your kart will seem loose, but I would say don’t change a thing to add grip, since our track usually comes in fairly fast and by the heats your are sticking. Lastly the YLC’s on our track are about 2-3 seconds a lap slower than the MG yellows. Last year when one of the guys switched to the yellows he passed the whole field in a lap just due to the extra traction. . </span></span></span>
