Recommended Posts

Hello.

I've got to put me cylinder head back on and I dont have a torque wrench, yet. I've got to get out this weekend or Iam going to blow. Is there any sort of way I can do this by hand with out destroying anything.

Cheers.

Rebonjour Squid.. only have vague memories of ty yams it was a while ago ;..does it have a gasket (copper) if so you can anneal it by heating it on a gas ring and then quenching it in cold water make sure you support it and dont melt it. Otherwise it's (from memory ) 4 studs...I have a memory of m8 threads with 13 AF nuts & washers...studs pass through the barrel and clamp the whole lot down,,,if this is the case and you havn't disturbed the base gasket why not do it by feel .....even pressure working diagonally .lubricated threads work better than dry (up to 60% more efficient).. Provided you don't overtighten it the worse thing to happen would be an air leak in the primary compression or at the head gasket...so be sure you have kill button handy...cant remember if it was these bikes but I can remember "lapping" jointing face of heads with valve grinding past and thick pane of glass..mention this in case head is "warped"....hope this encourages you also hope to see you at Vielles Tiges I think its 4/5 Sept Claude & charles Coutard run this excellent trial at Aurel ..not too far for you they prefer older bikes but also accept old riders like me!.

Hello Chewy.

I did check out what you needed for entry info here in France. Sorry it went out of my head compleatly. I'll send you a mail.

Thanks for that info. I've litterally just finnished putting the head back on as a friend of mine left his torque wrench with me but I just couldn't get me head around the conversions. He talked me through it over the phone. I didn't think I was going to get an answer to this post,impatient but Iam itching to get out.

Thats another great reply though from yourself cheers.

Iam know going to post another one as Iam having another problem.

Thanks alot.

Squid.

Dont worry about the info We are going to do 4 days Geuret...Vielles tiges and 3 days Aveyron this year... already entered Geuret and booked the boat...the problem (which I along with many others I've ignored) is that the organisers list the events as international....for which you should really should have an international licence (FIM rules)..... for which as an over 50 young you need to have around
