Today i thought i would spend a few hours in the garage on the F2 , so i went out and got my cylinder head out, this head has been getting me down as it had a seized bolt which the PO had just drilled through, and left the really rough corroded head fused to the aluminium.
The bolt i am talking about was one of the four bolts under the rubber pucks ( the ones people usually forget and hammer the shit out of their head breaking off fins before realising), anyway i had tried all sorts of things to get this out but it was corroded in there real bad and was in such an awkward place to access, i had an idea to get an easy-out in the top of it and jam it in tight then turn the head around and tap it through from underneath, after many attempts i won the battle and got it out. A proper eureka moment!
Also there are a few stripped threads in the head one of them a cam tower fixing bolt thread, so i for the first time used my helicoil kit drilled it out and inserted a new helicoil thread, i am so chuffed that i have got out there in amongst all mess and done something constructive,its back to full on enthusiasm for me , and to add to the excitement DS emailed me yesterday, and the box of new goodies i ordered quite a while back is on its way so i can crack on with the rebuild.

That's great stuff, it usually ends in tears but nice to hear this one had a happy ending, must look at my spare F2 head and barrels as I bought them from a breakers and they were a bit rough dismantling so I have a few miss treated bolts and studs as well.
Cheers

A bit difficult to recognise that lump of metal as having come from any bike Peter, let alone a 750 Honda. But I agree that getting something done on a bike that's been a bit of a downer when you just want everything to be straight forward & simples is a real heart warmer. That feeling of hearing the engine run after a major rebuild is a bit difficult to explain to the non-bikers out there. The missus would quite often bring me a cuppa tea out in the shed, would see the bits of bike strewn about all over the place & then enjoy the sound of the engine running again....especially if it was her bike that i'd been working on.
