Piston rings - where from?
 

Hi guys in looking at doing a major strip on my curvy sv 1 as its burning a bit of oil 2 had some bad vibes possibly crank or g box so need to strip to investigate an rectify the issue.
can anyone recommend any where to get the piston rings from as im struggling to find some.
Cheers
Ben

Zoran at twf racing can get them a lot cheaper from the states I got all my stuf from him and saved almost £100

Your local Suzuki dealer would be the best bet unless you're going to be doing interesting things with it...

However I think you might be better off investigating your problems before stripping the engine down as it can start to get expensive. What are your exact problems?

Re: Piston rings
 

Was yours really that much cheaper? I never really costed mine up you see.

Don't they run the same size piston as the 'busa? Wouldn't those rings fit?

Re: Piston rings - where from?
 

well its burning way too much oil at the moment seems to have lost some engine braking, valve clearances are a bit over due.
well started to vibrate a lot more than normal above 6k an box sounds a little whiny

Re: Piston rings - where from?
 

If the rings are the same size as the pointy, I can get them discounted from a dealer

Re: Piston rings - where from?
 

First of all I'd check the valve clearances and adjust where needed.

Then I'd do a compression and leakdown test.

Then I'd see what needs doing from those results before I'd be taking the heads off...

Might even balance the carbs while I'm in there. Change the plugs, the air filter etc. Whats the service history like?

Yup two head gaskets and the piston rings were £100 cheaper inc customs and postage I was amazed at the savings , even my buss pistons came from the us lol
No there a different heat tolerance and are smaller as the cylinders of the 'Busa are electroplated ally cylinders, SV has steel liners so the rings would bind on the cylinder as the steel expands more than the busa's, I think if I remember correctly lol

All info on clearance ect hear

Ps I ran Busa pistons with sv rings with .6thou skimmed off the bores of the sv cylinders with .7thou removed from the standard head gaskets to increase the compression

Re: Piston rings
 

Will remember that for next time. However I never did tell you how much my pistons cost...

And like Barwel I ran Busa pistons with SV rings with the slight rebore. Not with the increased compression (well not yet anyway) but with a cam swap. Never did get it dyno'ed, must do it for the re-rebuild.
