i have a stuart taylor fireblade kitcar
big clunck when changing gear and off and on throttle
is this normal first kitcar
i can turn prop 1/4 turn each way when car is in gear
any help thanks jon
Perfectly normal, with practise you can change quietly.
When changing up, foot off the gas and knock into the next gear without using the clutch, changing down always use the clutch.
You will also find when cruising it will rattle at lot, this is especially bad if the carbs are not well synced and dialled in, you can fit a TRT prop
which helps.
Clunking is a common complaint when not used to a BEC... but 1/4 turn of free play in the prop isn't normal. In gear and with the engine off you should have hardly any play in the prop' and in neutral there would be just a few degrees normally.
Surely the free play wil depend on the number of engagement dogs in the gearbox?
My busa box, with it in gear I can rock the car forwards and backwards about half a meter before it locks up against the engine.
Clunking, vibration and general noise is all common with bike engines.
Doesn't free play in the prop indicate a diff that needs adjustment.
A bit of clunking is normal, but like Adi says 1/4 of a turn is much more than normal at the diff end.
