ped overheating

my ped has just started overheating randomly.the same thing happened last year and i changed the coolant and then it was fine. today i drained the coolant out and put new coolant in and left the cap out to let the air get out. however it seems to have mkade it worse. apparently iot could be a problem with the thermostat? could i take the thermostat off without taqking the cylinder head off?

 

No, the thermostat is inside the cylinder head.

 

ok but whats that thats on the outside of the cylinder head on the left hand side?

 

some cardboard with electrical tape by the looks of things...





does it isntantly go sky high, or does it warm up like normal and just keep going ?

 

nah not str8 away. it warms up fine. its only if i keep it fukllk throttle for a while. and then if i stop or drop down to 30 ish the light will go off.

 

if ur free tomorrow laurence pop round and ill remove your thermostat, i never ran 1, more shit to go wrong.

 

Don't forget the rad doesn't have a fan, so it has no way of cooling itself other than moving forward.

 

i got 2 weeks off startin thursday. dont you have to take the head off to do that?

 

Not being funny, but are you SURE it's overheating? Any steam or water coming out anywhere? Just thinking it might be a dodgy connection at the temperature sensor or a dodgy sensor.

Don't trust that light. It's a lightbulb, not a mechanic.

 

Yea i was gona say that ... check the connection....does it seem to have lower perfomance when the light comes on....any steams etc, have a look at the connection on the head

 

two strokes make more power when hit
I wouldnt recomend removing the thermostat if i was you

 

my bro's bike runns a constantly open thermostat, takes a bit longer to warm up but works fine

 

no i dont notice anything different. i just dont wanna risk anything. it wasnt as bad today it came on once at the top of a really fat hill where the revs were like dieng out at the top. it rides fine but when the light comes on i like go real slow or stop and itll go off again.

 

Theromostats can and do jam open ,a jamemed stat or late opening stat
wont let the water flow around the engine and no water means a sized engine ,NEVER .run a thermostate on a tuned engine ,take it out and bin it

 

as dwarf says, ive never ran a stat on my peds and theyve all been fine

 

just let it warm up before riding straight off

 

I always run a stat, the only thing worse than a barrel getting too hot is one staying cold, cold seizes are a nightmare. do yourself a favor and clean your water pump out, flush the coolant system out (a hose pipe up a water pipe tends to do it) and get a new thermostat in there and she should run ok.
