ummm... *shuffles feet*......... the little bugger just shifted!!!!!
thank the lord for that! and thankyou very guys for the tips!! im very happy to say that i wont be needing them, just a new bolt. sorry to cry-wolf!
i soaked it for about an hour then re-cleaned the bolthead and used the most perfect allen key i could find with a lot of downward force. hooray!
it did have a lot of locktite or something on it which as you say, probably didnt help.
now... back to mocking up my klein build and cleaning engine parts in the lounge... 4 cans of cafferys, left over curry for tea and my girlfriend at her families house. triffic!!
no longer grumpy bear
