NEWS August 2017 Number 48 Tyro Economy As you will know we do all that we can to keep the cost of running a Tyro as low as possible. With this in mind there are a number of areas where, particularly with new clients, you may require a little more help than us simply putting information in the User Manual. The life of your engine is determined upon the rev range used and the type of lubricant mixed with the petrol. We control the rev range by instructing you which type of rear axle sprocket to use and we would like to control the lubricant too! Almost all of the Tyro teams use the Silcolene Pro2 and that means we can more easily predict the state of an those engines when it comes to advising you on a maintenance routine. Using any other form of Synthetic fluid makes correct maintenance advice very difficult to give; predicting the life of components becomes difficult. Your rear axle sprocket relies upon its correct alignment and the chain lubricant that you use. Again we suggest the Silcolene product, of course we use it on our "taster" karts and those chains are four years old! A number of drivers have moved on through age or size and they have their karts up for sale, Gennaro Coppola (sales@eastlinkuk.com), Phil Woodruff (philipwoodruff@aol.com), and Alan Swain (complete_home_imp@btinternet.com) and we encourage those interested to contact these people direct. A trap that many fall into is to use the kart meeting after meeting without ever cleaning the engine and the bodywork. Whilst you may not worry if the kart is dirty during your routine racing, others would worry when you come to sell it second hand. In general Tyros have been built to take the rough and tumble of racing without any noticeable effect upon them, but a dirty engine, or messy bodywork, will dramatically lower the resale value. We wash our engines down after use, either with paraffin and a paint brush, or spraying the dirt off with brake cleaner. After each meeting we clean the bodywork on the outside and the inside of the side pods using a wash down with "Elbow Grease". Polishing the outside of clean bodywork with a good quality car polish makes it easier to remove rubber scuffs when using one of the number of products on the web which aid the removal of rubber. All About SPEED Obtaining the maximum performance from a racing kart may be very complex, but with a tyro it IS very simple. Chassis set up has a standard of 2 spacers out on the front stub axles and 2cms in from the C clip on the rear axle at a pressure of 18p.s.i. Having run thousands
of laps over the life of the class we know these settings are RARELY BETTERED! However there is a mass of room for the driver's contribution! Probably the first diagram we ever showed you was this one and no matter how long you have been driving it is still the major rule. However good you think you are, unless you obey this rule when entering a bend, you will be slower than you should be. We have heard all of the excuses and not one of them comes anywhere near to being correct! Let us understand the rule. We need to be on the throttle as long as possible, brake as hard as possible, as near to the bend as we can and have enough speed left to take us quickly to the apex of the bend, where we can re apply the throttle. What do we see - 1) Drivers rolling 10 to 15 lengths with no brake or no throttle as they approach a bend. Many many seconds will be lost with this technique. Lap time is gained by shortening the distance between applying the brake and getting back on the throttle. That means braking later but harder! 2) Drivers braking, and then going back on the throttle before they enter the bend, then off the throttle again. Braking too early and not carrying enough speed into the bend. 3) Time and time again drivers are still not using the full width of the track on entry and exit to a bend. 4) When trying to overtake a driver who has a good line, we fail to see what you gain anything by going off line when THE LINE is always the fastest way round a bend. You only go off line is to overtake on a straight unless the driver you are overtaking has made an error on a bend. Back at Fulbeck, having missed out the June meeting, we see that they are still upgrading their facility and bringing in good numbers of drivers at the non MSA meeting.

Back for our last meeting of the year at Rissington the drivers and the team tents were certainly tested by the weather conditions. It was nice to see John Vigo and Tim Gillard visiting the Protrain tent discussing the Tyro concept; two stars of the sport.
The Rissington final promised to be very interesting with Josh Raistrick on pole, Jack Godden off two and up behind them Alex Tuzzeo and Lucas Romanek, all of whom had looked well on the pace in the heats. Jack led away and for nine laps, for each of them he was first over the line, but this hid the real situation, as he and Joshua they swapped places a number of times on many of those laps. Joshua was a proper pest, as he harried Jack over and over again, but even when he did get past, Jack just had the edge sufficient to get back his lead. Behind them Alex and Lucas made up the package of the first four drivers, with never more than 0.6 of a second covering them all. Further back Ben Cox was in pitched battle with new boy Tom Ralston, unfortunately a battle that was ultimately settled by the Clerk of Course. Leo Harris was next up to take home the novice trophy, perhaps the first of many for this young man? But what about up front for third and fourth where Lucas hounded Alex? Lucas always had a poor exit from the Dog Leg, he kept giving away three lengths, which he repeatedly pulled back on the rest of the lap. That was until the last lap when somehow by magic his kart was past Alex to take third. As usual, top quality racing where just the slightest error put a driver's position in jeopardy. Great to watch and even more fun to be involved on track.
Well that is it for this month, now we move into the 8-9-10 competition. Six race meetings where the four best heat totals are added to the best four finals totals. Points running down from 10 to 1 in the heats and 30 down to 3 in the finals for the top ten finishers. Steve 07711 606967
