Hi All, unfortunatly iv had to sell my DT125R
on better news iv passed my DAS so have a new bike meet Hettie 1998 CBR 600 F3 108bhp completely standard when i got her with 16000miles on the clock and one owner. have since got a black widow exhaust and changed a few thinks mostly look wise
i will buy another DT when funds allow probably next summer when i want to go green lane-ing.

So i got all my bits and have all been fitted. went for a 40 mile ride last night no leaks and no need to top up coolant,
on the way to work today 30 mile trip let bike cool coolant is just under rad neck so possibly just working out air bubbles so probs lost 5-10ml
this is using the copper gasket with copper sealant "spray a gasket" type of stuff
see how it goes on the ride home 
UPDATE,
had the head checked by a engineer buddy and its all flat so no warpage.
the workshops theroy for the blown head gasket.
in normal operation the thermostat regulates and pressurizes the system as @Calum stated maintaining a optimal temperature,
without a thermostat and having a free flow the "cold" coolant from the rad is being dumped into a boiling hot engine causing " thermometric" stress over time you end up with unevenly cooled parts of the head and develop hot spots "most likely over the exhaust port" this causes the aluminum to expand quicker than other parts and essentially crush the head gasket in small places. basically a slight bulge in the head surface. the engine then cools and the aluminum in the head then returns to normal, unfortunately the gasket cannot, so when you next start the engine from cold the gasket then blows past the weakest point your crushed head gasket !
i relise @Calum you have said this earlier doesn't hurt for a second opinion. but thank you i wouldn't have chased the thermostat route if you hadn't have clocked on to it
well parts should be here tomorrow including a new THERMOSTAT! so fingers crossed
cheers lads
just having a thought about copper gaskets again,
i was sure copper reacts with aluminum so i had a quick search on the net.
"Aluminum will be very susceptible to galvanic corrosion in contact with copper, assuming that the two metals are also in contact with a common electrolyte (such as water with some ionic content.) Almost any text or handbook on corrosion will have galvanic series table. The farther two metals or alloys are separated on the table, faster the corrosion of the less noble of the two will be when they are in contact."

so surely copper head gaskets are a bad thing, also copper doesn't and wont compress like the OEM gaskets do so there cant be any imperfections on ether surface,
but then i think copper washers are used for air and water tight fittings as a "gasket" as such so copper does have its sealing quilatys
so my question is the pros and cons of copper good or bad ?? what would be the advantages over the OEM gaskets.
maybe is should start a new thread ??
And the problem has been found @Calum & @Biker_123 you were right! tiny head gasket leak !

so what do you guys reckon go for another skim this heads already had 3 passes and the barrel 2 so that will be 5 thou taken of i would have thought?
also is it one of the guys on here selling the copper head gaskets on ebay? i know older engines used to have copper gaskets... are the rated highly for the use on DT's ?
as always advice aprecated
Cheers @Biker_123, was looking for an attach image option, (i presume that has been disabled limited server space possibly?)
