So having rambled on about everything but the thread topic (apologies for that), I have had a look at the subject ie Tillotson T4 Kart.
First thing is that Tillotson are offering a complete kart/ engine package so no wondering if your engine will fit on your chassis , which engine mount , why the carb is where the back wheel goes etc .All done for you.
Every thing is spec. Sealed engine no mods.
Spec carb , exhaust, filter. even oil!
Chassis wise ,‘Spec’ frame, axle ,hubs, rims , tyres,seat, bodywork , the lot.
Now some may not like this but the alternative seems to be to have a vast array of axles ,hubs ,rims etc, all of which ’ make a difference’ but few seem to know what or why.
Only thing that is clear is they are going to cost money, lots of it.
Engine is a 225 cc 4 stroke copy of the Honda GX built in ’ our factory in China’
Claimed 15hp. PVL alloy flywheel and ignition with 6,500 rpm limiter, Billet rod with shell bearings, Tillotson diaphragm carb, decent exhaust, pull start, sealed with log book.
Chassis is pretty conventional ‘European built’
Spec 50 mm? axle , self adjusting brake, vented disc, spec. aluminium rims, adjustable castor / camber/ ride height/ Ackermann.
Kart weight around 155lb.
Tyres are Maxxis ’ specially produced for the Kart’?
Quoted price €3250 .plus taxes.
Seems a reasonable proposition for all those wanting a ’ level playing field’ particularly in regions without an established comparable adult class??
