Formula TKM News

Well let’s start this month with something totally non technical but which will be of interest to hopefully everyone in the TKM 2 and 4 stroke classes – the Maxxis Formula TKM Festival.

The exciting news is that the event is returning to Kimbolton following the club’s resolution of a planning problem which effectively put a stop to Friday testing.

When that problem first arose it was Whilton Mill who very ably stepped in to offer this major event a home for the past three years. Not only did they give the event a good home but also managed to chart out some revised formatting which worked to benefit the event.

But with Kimbolton now back on full song it seems only right to return the event to the circuit that worked with Tal-Ko to create the event 14 years ago. They have put many years of hard work into making this a must event to attend, not just for the racing but for the good spirit too.

And even better news is that Kimbolton themselves are just starting on some major work which will see the creation of a new toilet/shower block, new catering area, spectator viewing and a substantially revised dummy grid and park ferme.

So put the date of August 12-14 in your diary now because Kimbolton are determined to mark their return with a bang!

Next some more good news for all of you who have to buy TKM engine parts – and let’s face it that must be pretty much every single one of you reading this!

Mr TKM, Alan Turney, has created some engine parts exploded diagrams that quite literally show every last little item on the BT82 2-stroke and K4S 4-stroke. What’s more every individual item down to the last washer is illustrated and has a clearly shown part number making it incredibly easy to sort out what you need.

So absolutely great for ordering and identifying parts – and also very handy if you take something apart and then can’t remember how it goes back together. Even little things like the order of gaskets etc on a carburettor are shown.

And better still, the whole set of technical exploded drawings for both engines can be rapidly downloaded onto your PC and printed out – all free of charge. Or of course you can tap into the illustrations from the circuit using your iphone or equivalent. What is more, you can also download a full parts price list from the same website so you can know exactly what your bill will be. Just go to www.tal-ko.com and get downloading.

Personally I think it is a fabulous move and really makes a big difference to understanding your engine and all its parts.

I recall when I first started in the class in the days of its inception you didn’t even get a bit of paper to recommend carb settings let alone anything else. Tal-Ko, more than any other engine manufacturer, have made great strides forwards in this respect so give them a pat on the back.

Now to Shenington, a club which has a strong entry of TKM 2-strokes. The club there have just been given the OK to proceed next year with a ‘Clubmans’ version of the Extreme class in addition to the normal Extreme class.

Karts competing in this class will still meet the latest TKM regs but are bolted down to some cost cutting criteria which should very successfully keep costs as low as possible.

The karts themselves must be of a design never intended to house a torsion bar, They are not allowed data logging and must run with a fixed sprocket size regardless of weather etc. Rear axle must be 30mm and no front hubs allowed.

Interestingly on tyres they must compete with used ex S1 championship tyres which will be sold to them at £30 a set. Bargain!! Oh and special test and race entry packages.

It will be interesting to see how it goes. Initially they will run with the Extreme normal grid but if there is sufficient take-up then they will be given a separate grid.

The club are hoping for costs to work out at about £100 for a race meeting. I remember working on the same amount about 20 years ago so that sounds like excellent value. I am sure the Shenington club will be pleased to provide more information.

And finally we are coming to that point in the year where many fair weather karters very sensibly decide to park their machine for the winter. Looking out of the window who can blame them! But before you do, a few easy things to do that will save you time.

The insides of the carb don’t like being left either full of petrol or conversely dry with just old deposits left in them which turn into a sticky goo. Do that and almost certainly you’ll have trouble first time out next year unless you thoroughly strip and rebuild the carb.

So just prep your carbs for the winter by squirting a little WD40 through them. It will leave them in much better condition for when you want to use them again.

And while you are at it then it is a good idea to drain off everything from the fuel tank and leave that dry. When you go to use it next year give it a good blow through with an airline, replace all the pipework with new inside and outside the tank and make sure you have good tight seals on all connections.

To complete the fuel jobs get rid of any mixed fuel you have in cans. It goes off with time so best to slip it into your car fuel tank if a small quantity. Or, you can put it into a suitable container which you then use to rinse and clean your chains. Mixed 2-stroke does that job very effectively.

A small tip on fuel to finish. It is all too easy to have fuel cans that are mixed and others that are not. Clearly if you put pure fuel in your tank you will end up with a seized engine. To be avoided at all costs.

To avoid that, as soon as you have mixed a can of fuel and oil put a cable tie through its handle. Just remember to cut off the tie as soon as you have used the last of the contents and you’ll never be muddled again.

Hardly used tyres can be purchased at a considerable saving on the new price

Times are hard and money is tight pretty much everywhere, but quite rightly people still want to have their fun. Formula TKM karting is full of people like that so this month let’s look at ways you can save money on your karting and keep the bank manager happy.

Let’s first of all look at engine servicing and rebuilds. The short answer here is don’t just ignore servicing to save money because it will probably cost you a lot more in the long run. A blown up engine can be very expensive. But there are ways you can bring down your servicing bills.

For example if you are doing club events and keeping the maximum revs sensible then you can very easily let your BT82 2-stroke engine run to 20 hours with no problems. Years ago I recall my son winning a club series with no rebuild all year and the engine up to 25 hours.

The important point is to make sure the engine is running fairly rich through the rev range and to keep the maximum revs down to say 15,500rpm. Bear in mind that the Club 100 operation which uses the engines for high performance rental use takes them up to around 60 hours between rebuilds just by keeping the revs down to 14,500rpm or so.

That doesn’t mean you will be slow. Use a slightly longer exhaust joint to maximise power in the lower to middle ranges. You might even go quicker because high revs do not necessarily mean high speed.

On the subject of rebuilds do shop around for prices. Some charge too much for what should be a straight re-build. And remember that a full factory rebuild at Tal-Ko is at a very sensible rate starting at £235 + vat for a direct drive engine.

On the TKM 4-stroke engine, it just goes on and on which seems like forever at 60+ hrs without needing to be touched – so long as you change the oil every time and occasionally service the clutch. Real low cost racing.

Give sensible thought to how you use your engine and your track time. So for example if you have two engines then my advice would be to pick the one that is your favourite and keep that for racing. Use the other one for all your testing etc. That way you can afford to run that test engine a little richer and maintain its life to the maximum.

And on the subject of testing…ask yourself the question are you seriously testing set up, lines, etc or are you just getting some track time the day before a race meeting to hone your skills and have some fun?

To be honest a lot of people fall into the latter category and good luck to them. This is after all meant to be a sport to give enjoyment. So if that is the case then be sensible on your pocket and use older tyres, engine etc for the testing and the best stuff just for racing.

Talking of tyres let’s just look a little further into that area. It is a simple fact with any tyres for any form of racing that the newer and fresher they are the softer and therefore faster they will be. That is not to say that you cannot get many hours use out of tyres but simply to state a basic fact.

So use the principle that (wheels permitting) you use older tyres for testing and the best ones for racing. With the new slicks we have for this year in 2-stroke you’ll want to gain experience with them but if you are just having some testing fun then use your old tyres.

As far as wets go then ideally you want some older wets to use for drying or damp conditions and save the best for racing in deeper water. And don’t forget that the slick tyres will work surprisingly well in just damp conditions. It is only when standing water is present that wets really come into their own.

And whether wet or dry tyres don’t overdo the pressure. Too high a pressure and the tyres get too hot and lose grip – and they also will harden up the rubber for the future.

Oh and a final tip on tyres. Get friendly with people doing the S1 series. They will frequently sell off used tyres in superb condition at nominal cost which are ideal for club use.

Chains – buy the best quality chains because they last longer. They need to be washed thoroughly after each event and then thoroughly lubricated every time out. Beware using chains past their best because if they break it will mean the crank needs true-ing up.

The carbs will go for ages without any problem. Don’t just put new innards in them for the sake of it. Replace the diaphragms etc when you can detect on a tester or in use that they really are worn out.

Bent bodywork or bars? If it is bodywork then try soaking it in a bath of hot water to let it get nice and supple and then try to straighten out the damage. It does work – and if you get in the bath too then you really are making a double saving. Mind you a duck is more fun! Minor bends in bars can be sorted with careful effort but make sure you are not leaving the bar weakened or broken.

Buy sensibly. That means buying sundry items like nuts and washers from somewhere like Screwfix where they cost next to nothing in bulk. Buy your specialist needs at the track and do your best to avoid the extra burden of delivery costs that come with orders bought over the internet.

If you need tools then don’t just rush to Halfords or Snap-On. Look on ebay or on stands at exhibitions and you’ll find tools at a fraction of the cost that do a very adequate job.

And if you are travelling away to events and using a hotel then remember that hotels are struggling at the moment and offering all sorts of discounts to people making early bookings. Remember too that if you go for a dinner bed and breakfast rate then it will always be better value than paying for B&B and then ordering dinner extra.

Finally, if you need new crash helmet or race gear then look around for the best deals. Plain coloured helmets are always cheaper than the fancy coloured ones but are in fact the same product. Have fun!
