Title: 2 things!
Post by: andy230 on November 22, 2006, 10:45:24 AM

Hello chaps-

1.  Anyone got a tightening sequence for the SRX head?  Obviously diagonals for the 4 bolts but what about the two nuts fore and aft??

2.  This is gorgeous!!!  (even if the publication is crap)

Aye Andy,

Ohhhhhhhhhh dear!!!!!!!!!! I could be smitten, Aprilia.

As for your tightening mate. Tighten the 4 bolts to 25Nm (2.5 m-kg, 18ft-lb) in the usual alternate diagonal sequence [Of course you marked the bolts so as to correspond with the holes they came from!!]. Then tighten the 'acorn nuts' alternately to 20Nm (2.0m-kg, 14ft-lb).

Did you buy a genuine Yamaha new gasket?

All the best and I hope it goes well.

Cheers, Bill

I spoke to martin sweet at slipstream.

Apparently he nips the acorns, then torques the bolts (diagonally; and yes, I jabbed them into a bit of card, so they go back in as they came oot!), then goes back and tightens the nuts properly.

He said WD440 on the threads, and a wee dab of coppaslip under the (copper) washers.  Good to know....

I had to buy another torque wrench- tho one I had could have put the Queen Mary together!!

And yep, genuine gasket.  Why is the norton one 4 quid, and the Yam one 25???!!  Pretty similar looking things!

Cheers anyway

ps. yeah, that aprillia would be good as a supermono racer....
