Hey Old School Guys...
I'm organizing the parts for my GP1200 rebuild..
My question is about gaskets...
What should i use...???
Seems i can get a full Genuine Yamaha set for $158:69 from boats.net..
This doesn't seem to bad..??
Or are the aftermarket versions any good or better..
Through i will say i'm NOT impressed with "WSM" stuff..
Are there others i might consider..??
Also looks likely i'll go one size over with the pistons..
Will i need a different/larger head gasket than stock..?? supplied in the gasket set..??
One last question Guys..
I'll be looking to source a set of one size over pistons..
Seems from my research that Pro-x would be my best option..??
Is this accurate..??
Any one have any available or know of a good place that will supply them..??

I have run across a few Cometic sets and they are top notch. Stay away from the WSM and SBT neither is worth the apparent savings. I have been lucky and got bargains on ebay but they are rare these days.

That was my thinking on these "pattern" gasket sets..
I've seen the odd cometic gasket on fleabay myself on occassion..
Through its usually only one or two pieces..?? so no real use to me..!!
I'll get onto boats.net in a day or two..??
What about the oversize thing..??
Will i need to get a larger head gasket..??

I am running .5mm oversize pistons with the stock gasket so I see no issues here. I will go measure one if you wish.

65U head gaskets are good to 86mm.

The intake/reed gasket must have the oem type steel shim with foam coating.
IMO this is one of the reasons for slow GPs, it was worth 2 MPH on mine.

Thanks for the input..
I've went ahead and ordered a full gasket set from boats.net..
Will this set have the reed gasket mentioned..??
Its part #.65U-W0001-00-00
