Bike getting hot could be headgasket.

Yeah, the head gasket is on my radar.
The oil looked ok when I changed it - so did the coolant, but I will check the consistency tomorrow.
How big a job is it to do the head gasket for a garage? Ball park cost? I think that may be a stage too far for me to do yet.I actually put the power valve back to original position as the exhaust got very hot very quickly (smoking from end after I stopped after a 5 min blast)

haha I would say leave it open its boring closed I could fall asleep riding if it was not wide open but I will say I have seen threads where there is a bit of controversy so think it's best you know how your bike runs first so you will tell if it rich or lean through the rev range

Here's one I prepared earlier !

Hello and welcome'
Get the servo retro fitted and have a working powervalve. Best of both worlds.
Exhaust gets hotter because you spend longer times at higher rpms. Refer back to my previous statement. Get the servo fitted. Less stress on the engine.
I would start simple first, check the thermostat, they are probe to failing after zo many years.
Head gasket is not the same as a four stroke. No valves no nothing to go wrong.
Buy only genuine or athena gasket, skim the head like described in my tutorial, then boom, good to go.
Nice bike.
