Don't see any reason why not .... But possibly tempted to use some chemical metal in the grove to support the gasket Quote Link to comment
Jdeac Posted July 1 Author Share Posted July 1 Wasn't sure if it would need tobe machined out. And the barrels move up. With the appropriate thickness base spacers 1 minute ago, Duckndive said: Don't see any reason why not ....

inmate Posted July 1 Share Posted July 1 ‘scuse me ignorance, just what is a piano wired block? What’s it used for and what are the benefits? cheers David 1 Quote Link to comment
DAZ Posted July 1 Share Posted July 1 (edited) A piano wired block has a groove machined in the top deck around each cylinder to take a wire metal ring ( the so called piano wire ) which stands proud of the deck and when the cylinder heads is fitted bites into the gasket it is usually used in extremely high compression , nitrous or high boost applications Edited July 1 by DAZ Addition 2 Quote Link to comment
bunk Posted July 1 Share Posted July 1 Across the pond we call them fire rings or a top fuel hoop. Grooves are cut in the block and head. 1 Quote Link to comment

Last set i had done were Air Cooled ones i took out all the studs and it cost £100 for the boring and that was quite a few years ago ... Quote Link to comment

I have some carrillo rods and heavy duty studs and nut. Also a ported head done by mistral. Guess I'll want to upgrade carbs aswell Quote Link to comment
Gixer1460 Posted July 1 Share Posted July 1 Aftermarket rods really only needed for daft CR or excessive rpm's. Turbo's give rods an easier time. More rods have died due to oil failure than any other cause! Stock gsxr rods will survive up to about 250hp when gassed, nearer 280-300hp when turbo'd Quote Link to comment

They are also heavier than stock rods and without re-balancing will produce more vibes - another bonus LOL! 1 Quote Link to comment
jonny1bump Posted July 2 Share Posted July 2 Yep just check sealing surface is ok relative to gasket and make sure you pick piano wire out. This is how my turbo bike is currently and actually cured any oil weeps. Copper good if its brand new gasket. Quote Link to comment
