550 cylinder ridge
Hi 1974 GT550. The bike has been sitting for a number of years. 9400 miles. Is there supposed to be a slightly bigger diameter ridge in the top about 2mm in the cylinder bore? It doesn't seem like wear.

Re: 550 cylinder ridge
I brought the cylinders to the machine shop yesterday. Turns out the ridge was wear and luckily, I didn't order the first oversize Wisecos because the bore was already 61.5. I ordered +1.0 from IMD in the UK. I am hoping these are good pistons but at least they have been in business for years . Lots of cleaning to do while I wait for the pistons but I think that this will be it for actual repairs. Famous last words, I know...
Interesting to note that postage from UK to Canada is cheaper than I can send a package to anywhere in Canada...

Re: 550 cylinder ridge
IMD did the rebore on my 550J a couple of years ago. It runs very well & I would have no hesitation using them again.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

Re: 550 cylinder ridge
Thank you Alan.
Now, I am looking at the crankshaft for a rebuild. The only complete seal and bearing kit I see is from Cruzin Image. Has anyone used these? I know that I try to avoid their pistons although some Kawasaki guys have used them with good results. They aeem to be the only one where I wouldn't have to go to ebay and source each individual seal and bearing. They also have a kit with rods included.
Has anyone any experience with these kits?
Thanks Dave

Re: 550 cylinder ridge
I have had several 550 cranks done (and a 750 one) by Barry Wilkes in Birmingham. He owns & runs Kettle Clinic forum & kettle clinic on facebook - in fact he has my 550B that I need to pick up after some work that's just been done.
His email is baz99w@netscape.net .
Mention my name as an introduction & what you need.

Re: 550 cylinder ridge
I have received my +1.0 IMD pistons. Don't want to seem a doubter but clearance is listed as only 0.0015 inches. Wossners for my Kawasaki triple is 0.003. Has anyone any experience with these pistons. Their clearance requirements seem a little on the tight side. Or, is it the superiority of the Suzuki engine?
Just curious.
