Hi,

I finally have got the chance to start riding again after several years out.

Last time I rode I had to use my brother's spare 95 techno, due to more problems with the scorpa I had, the techno started making a strange hissing noise, from the front of the engine block, in time with the compression, it didn't seem to be anything to do with the exhaust. I immediatley stopped it and pushed it back to the van. We were planning to get it looked soon after but this never happened, but now I've moved house and have a nice garage to work in Iam keen to get it sorted again.

I haven't started it since but it will turn over and there is still a hissing noise?

Any one have any ideas as to what this could be? Is it likely to cause further damage if I start it up again... I have checked the gear oil etc and the fuel mix was as advised, there was plenty of coolant and the fan was already set to run all the time.

Another problem was undoing the oil drain nut under the sump guard.. the allen key nut simple wouldn't budge... I had a brand new allen key of the correct size but it was going to move.

I admit to be pretty useless mechanically, only good at breaking things, but am very keen to learn how to repair them if possible.

Any help much appreciated,

hoping to upgrade to a newer bike soon if I can ever get this one running well again.

Thanks Andy

Sounds to me by your description that the gasket

between the crankcase halve,s or the cylinder base gasket has

blown,you will have to get someone to kick it over while you

have a good listen as to where it is coming from!

.. the allen key nut simple wouldn't budge... I had a brand new allen key of the correct size but it was going to move.

Try applying heat (without setting fire to your bike) - even a good blow with a hair dryer is sometimes enough to free the threads up.

Most drastic option... permanently fix the key in with an epoxy resin, however you will require a new sump plug and key once removed.

thanks for the advice,

cheers andy
