Topic: I received an 81 Suzuki GS450E, I want to go 3.5mm over.

I just set the GS 450 big bore engine carbs, there were multiple opinions like "he set the valves wrong" and other sh1t.
I have been doing this since I was twenty something and close to fifty now, took me almost ten minutes to figure out what was wrong and sure as hel1 it was not my doing 

Synchronize the butterflys  ?

Dellorto carbs, left slide was backwards.

I am updating this thread to say that I tried a custom piston maker who is connected to Carrillo pistons,in a way.. I had many conversations with the man and explained I was going to use the GS500E cylinders which are 74mm STD i.d.(also,the height of the 500 cylinders is .050" higher than the stock 71mm i.d. GS450 cylinder block and the 500 piston's ring stack are also a bit higher)along with my GS450 cylinder head I will be running.

I spoke with the piston designer and we had many communications including emails,texts,etc. over the course of months, and I made it clear I wanted a GS500E height/style piston with the dome design of the GS450 to match the GS450 cylinder head which I plan to use.
I sent him very good examples of what I want;a used,stock GS450 and GS500E piston,plus a used connecting rod,which I purchased especially for this process,which is what this man asked for.
I also connected him to my local machinist and purchased a spare set of crankcases for height measurements,which the machinist did and I thought, "these are going to turn-out great".

Well,4 months ago,I received a box w/ the set of 4 pistons he sent to me.
The designer made a few 'mistakes'..  :he sent me 75mm(STD GS500 are 74mm)exact copies of GS500E-style custom pistons(including GS500E domes  ),which had all the bottom skirts cut-down lower !     Guaranteed to piss me off,plus the man refused to refund me my $1500 for these 4 wrong pistons !

I have completely lost trust and $ in this transaction with this individual,who lives in NC.
The man told me "I will only do a 're-make' for you,to correct the problem/mistakes.: I will not give you a $ refund" 

I see this as exactly what it is: a total loss to me.. Wow,I've had too many of this type of thing in my life   

I've decided to run my freshly machined STD/stock set of 71mm pistons and cylinders for now,but I haven't given-up on getting a set of proper 75mm large-bore custom pistons later.

I'm looking for a small,good piston designer who I will be able to work with;a person who will give me a mock-up piston which we both agree-on, before sending me the completed job.

Sorry to hear about this bill.   Did you provide drawings with critical dimensions?   Not sure how this could have happened, was there a language miscommunication?

Hi Stev-o  , yes I did.
I think the man has too many thoughts bouncing around in his head;but I shouldn't have to suffer for him. I only want my $1500 back,but the man refuses.
