I look forward to following your progress, Chuck.History tells me you're going to crank out another winner!Carlo
Oh man!! That will explain the leaking. What a mess. Might want to check with Milich about a new cylinder. He's been selling parts of a beater Lario I believe. Think your seat came from it maybe? Good thing you started early on this one. Wait til you run it with two good cylinders! :o :o-Kevin
Seems like this cylinder has lived through a valve drop :oWhat's the cylinder/piston grade A, B, C??Stamped on top of the piston and the top cylinder cooling fin.Depending on the grade, I may be able to help you out if you don't run into a cylinder with the right grade, or en cyl/piston kit of any grade.A cylinder from a 2V will do too, just make sure it's the same grade as the piston.CheersBrian
Ok. What's the ABC, bore diameter?
Yes sir :)
Guzzi pistons and cylinders are matched sets. The published bore size is one thing but, piston to cylinder clearance is measured in thousanths so, sets are made and denoted by letters a b or c to assure the clearance is within tolerance.Chuck, I have an nos clutch, some intake boots and I think some con rod bolts from a purchase I made several years ago. If those items come up on your parts list let me know. Ill make you a good deal on them.
Check this place Chuckhttp://www.gutsibits.co.uk/pr/TheShop/index.php?q=piston+rings&f=d&Model=14I have bought rings here - although in the UK...Fair price.Check your cylinder/piston sets - if it's Gillardoni's you have, you will need rings that match these kits. They are not the same as OEM's, but from what I can spot on the pic's you have OEM's.Good luck!
Looks like standard stuff, stamped C. Looked up the dimensions in the manual, and I'm amazed at the tolerances of the 3 different sets. 3 ten thousandths of an inch?? :o I'll bet Luigi's ruler doesn't measure that closely. ;D What do they think this is, a turbine?
;D Yeah snazzy little bugger - C is the biggest bore - same as mine....unfortunately I only have a couple of A's with no pistons.I do have a 2 C's including pistons.Best to get them in the US, due to postage, but if you have a problem finding a C cylinder or piston/cylinder set, let me know.Replating is in most cases far more expensive than a good used kit. I assume you have C's at both sides, if not, I'd get a matging kit to replace the dinged up cylinder with matching piston, so you have identical grades at both sides, but that's just me.Martin Hagemann may be able to help too - he's the Lario guro in the EU. http://www.guzziepiushop.de/shop/CheersBrian

"Good used" is oft times false economy. At around $209 per bore, I don't feel that replating is that expensive and I'm "frugal". A nice, fresh bore to start with is a good thing IMO. Do it right the first time.
I won't argue that, Charlie.. but then where do I get the rings for it?
Eeks! I'm a 'Merican. ;D I did run a German duplicating milling machine one time, and taught myself just enough German to run it, but...Merican's only know one language, and don't know that one very well.. :DDoing the metric to 'Merican conversion on the cylinder size.. the largest A cylinder is 3.1498", and the smallest C cylinder is 3.1500. I have a *really* hard time thinking it makes a nickles worth of difference. I would think that by the time a hone is ran through an A cylinder just to clean it up, it would be a C..or bigger.. <shrug> or, do you not clean them up?
As I posted earlier on the Small-block Guzzi Group, Deves sells ring sets for Larios (and many other Guzzis): http://www.deves.com/devesrings/cycles_MOTO_GUZZI.php . Part no. MC-130. Harper's sells them too. They're the correct material to work with all Nikasil type platings according to the tech guy I spoke with there. MG Cycles lists all of the gaskets, so no problem there. Most likely Harper's has them as well.
