[Supra-K]

anyone?

 

[AaronsSupraMKIII]

Don't have a clue, but hope someone answers cause I need to check mine in a few days too. :naughty:

I have an idea...take a look in the TSRM!

 

[Supra-K]

ok haynes says .008 intake and .010 for exhast, the trsm says .015-.020 intake and .020-.030 for exhast, so Im a little lost, but whatever Ill just go with trsm anyone know where i can get some shims for cheap?

Now it gets complicated.

You need to pull all the shims that aren't in spec, keeping track of where they came from. Then measure them with a micrometer and calculate what thickness you actually needed in each spot.

Then check to see if you can swap shims around to get most of them in spec.

Then either get your remaining shims ground down to fit at a local machine shop, or buy new ones if they need to be thicker.

Best place to get these for cheap is your local Yamaha dealer, same shims as they used in a motorcycle engine back in the day... damnifiremember what motorcycle engine, though. Some searching might turn that little tidbit up.

ok i get the part about pulling the shims and measuring and stuff but according to the trsm they are all off?

Go back and read it (tsrm) again, you're getting numbers confused. It also tells you on the bottom of the hood.

It's .15-.20mm and .20-.30mm, not inches.

 

[Supra-K]

O hahah i was looking at mm instead of inches man I keep havin moments like that on this forum, I need to pay attetion or something

 

[Supra-K]

ok so for the most part I need to do some reshiming a majority of them is off Ill see what I need then hit up the fourm for the shims

This will make your life easier (at least figuring out what shims to use)

[Supra-K]

wow thats badass Im using that once I get a Micrometer

 

[Poodles]

that's in the TSRM as well, but it's nearly impossible to read on the online version...

it's not quite as easy to use either LOL
