Motor is not rebuilt... 12k original miles and runs so well it puts all my previous new bikes to shame.
You just looking for an opportunity to crap on someone’s day?Thanks for the pep talk but not sure it’s relevant. May get it rectified or when that happens I’ll rebuild it. No worries. But for now… wasn’t asking.
Good question. I forget. I just dump the oil and clean the screen. You get use to the right hand shift and backwards pattern to the trans.?
Agreed. If not already done the original cylinders will have Hearing that crankshaft grumble is not a happy feeling. Btdt with my V7 Sport long ago. After that, all has been even better than ever.As far as oil, I run Castrol GTX 20/50 in the engine and plain 90w or whatever the factory manual recommends.Welcome to the V7 Sport world, Richie. It’s a great place to be imho. Mine is just a hammered old bike, nothing special or super original but feel glad to get in touch if I can ever be any help. Clint
Richie,I didn't mean that in a sarcastic way. Just realistically bringing to light a common issue with these old Guzzis. I have Gilardoni cylinders on both my V7 Sport and Ambo. You'd be surprised how many owners don't know about the issue. Love the color by the way. Mines a '74, so it has left side shift. It's does have the reverse "one up, four down" shift pattern. My mind adjusts to it pretty quickly, but I do miss a shift every now and then. Charlie Mullendore (Antietam Classic Cycle) did the complete restoration for the previous (very brief) owner.http://www.antietamclassiccycle.com/v7_sport_restoration/CamPS - And yes, you should add some moly to the gear oil in the rear drive.
My 2 cents, been using Shell Rotella 20/50 in my Eldorado, V7 Sport and every other Guzzi Twin from the 70’s I have owned. With the Eldorado and similar vintage Guzzi’s without an oil filter I change oil at 1000 mile intervals (fully rebuilt motors).
Check with a magnet like Charlie suggested and go from there . The tough part of this chrome bore issue is it is a plain fact, like going over the bars at highway speed with no helmet. It may sound too abrupt to say fix it or else, but these bikes have issues & a cost of admission that cannot be avoided with impunity. With that said- The upgrade nikasul cylinders with pistons & rings on my V7 Sport were purchased in late 93 via Parts Is Parts, sold specifically by MG to remedy the chrome bore problem. They came in unopened factory Moto Guzzi marked boxes (still on shelf as souvenirs) with no markings on cylinders, external or otherwise. Externally, they look just like the chrome cylinders I removed from the bike. Over the years, I’ve had people warn/criticize me when they didn’t see Gilardoni on the outside of the cylinders. Some even told me I probably only got plain chrome cylinders. Someday I might be smart like them... I know they had the best interest of my bike in mind.NOS pistons & rings are here waiting to be sent to Millennium with the cylinders for nikasul plating when the time comes to do the engine on my V700 Corsa record project because 700 cylinder kits have been NLA for a while and probably will always be. Not sure if V7 Sport Gilardoni cylinder kits are still on-shelf items. If not, Millennium is the company I would contact to replate your original cylinders.This CX100 has Gilardoni hallmarks on the cylinders, which confuses me if the 1000 engines normally had either iron liners or Nikasul as oem. Looking at old Raceco catalog last night, now I’m curious if it may be a 90MM nikasul kit or similar on the engine along with the other mods.
You Don't "have to" remove the engine to do the rear main. Search here for crabbing the frame. Just pull the trans out.If you have changed the rear main seal, and it was done right, it shouldn't leak. But, the paper gasket that seals the rear main bearing to the block can leak over time. Another thing in there that can leak is the metal breather tube gasket or even the disc that closes of the cam opening.Before going after the seal, you might want to check the breather box lines that enter the bell housing. If one is leaking, many times it shows up like a seal leaking.Tom
