Hi I am about to replace the head on an Aprilia rs 125 and have a question about torque wrenches, small spaces and tools. Getting the head off was a real tight fit, lots of missing skin and the spanner got about 1/10th of a turn each time, it took ages to get it off and I am concerned about how to get the bolts super tight again in such a confined area. I can't get a socket or extender straight onto the bolt as it's being blocked by the top of the head. Does anyone have any tips on what tools I should be looking at? I was thinking of a universal socket thing but I'm not sure if it will fit or work as it's very tight height wise as well. Also the manual tells me I need to use a torque wrench, but I cant see how I could get on in the space without some kind of extenders. Any help / links would be very much appreciated. I can post photos later if this is not clear. Thanks.
