The rear drive is different in that the splines stick out farther than on an EV or most anything else. There is a longer spacer also, the one that pushes into the drive. Places the whole assembly about 1/2" to the left.
Different axle, brake holder and another added spacer by the brake. Only Guzzi would make 6 new parts to install a cheaper wheel.

All I can tell you is I used the stock calvin axle, caliper hanger, rear drive, pressed in rear drive spacer. I installed the 98 EV tubeless wire wheel, and it all fit perfect. The wheel is centered relative to the fender and centerline of the bike. The bike does not pull to either side with hands off. Through the gap I can see the splines are fully engaged. The CalVin has the special frame and lower rails that pushes the entire engine and transmission 1/2" to the right, so that the swingarm could be 1/2" to the right (that 1/2" number is approx). With the rear drive moved to the right, and the extended spline coming out of the rear drive (extended to the left), the wheel ends up being centered.

Am I concerned about some small front to rear misalignment (if there is any)? No. When I was racing inorder to get a 4"x18" rear astralite wheel into a notched but narrow short swingarm, I moved the wheel to the right 10mm or .4". My race bike while it would tend to fall to the right if ridden no hands, never wobbled...

That's what I wanted to hear. I am having to do some interesting offset for my sidecar rig and was hoping it isn't a big issue. Have done a bunch of research on how different parts were used to fit the skinny tube type rims

Realized I was never going to be comfortable on the stock saddle as the step up to the passenger section was too far forward and pushed me too far forward. Having done a $350 Sargents saddle rework on a number of bikes with limited success, I figured I'd go the local auto upholstery shop and see what they could do. This cost me $40. The guy made me do the initial carving on the foam, that way I couldn't complain...

He reused the original cover obviously. Sort of reminds me of the rework the factory did on later Cali II's to move their passenger bump back.

Have been thinking alot about how to solve the wind buffeting around my head and helmet. The CalVin comes with an abreviated windscreen in the lower regions and I think that is the cause. This is so it clears the stock directionals and stock running lights. I decided to try a different route up front. Partly because I am a contrarian, but for other technical reasons. The driving lights had to go, one because they suck up too much juice, and two because of weight. I did want to preserve some of that look, and so I decided to replace them with some tractor trailer style lights (this is the contrarian part, most folks go with tiny little turn signals). This allowed me to remove the stock directionals, but made for a large gap below the windscreen. I was going to have a custom windscreen made, or find an undrilled harley style, but after looking at this a bunch. I decided to go with the auxilary wind deflector route. I know some are available from various sources (>>$100), but I didn't want any that mounted on the fork tubes as I have mine moved all they way up to lower the bike, and have no room for attaching them below the lower triple clamp. For $7 in stainless steel angle brackets from mcmaster carr (PN 1556A65) and a $15 piece of lexan from home depot, and some stainless nuts, bolts and washers I had kicking around I did the following. All I can say is it has cured the helmet buffeting...

 ;-T on the lowers, looks like a great job and will certainly help with the buffeting, nicely done. looks good too. I made almost the exact same thing but with chicken wire and LOADS of black gaffa tape from the bottom of the screen to the spots a few years ago on my Calvin... it looked absolutely awful but really helped with the buffeting...

then I found a swannee, which doesn't look great but is absolutely the bees knees for countering buffeting at any speed and a useful place for putting stickers of every country that you go through...

nice work

the H&H from Harpers is a good reproduction of the Swannee, not quite as strong as the original swannees, ie will flex a tiny bit over 90mph. It mounts on the handlebars and upper forks. Excellent functionality....

CORBIN arrived. Zero miles...
The seat back for the driver is moved back relative to stock, and it feels firm like Corbin's do. Can't wait...

$13 ebay "corbin" compatible backrest. No doubt chinese, but it works now that I assembled the mounting post to the pad correctly and added an adjustment stop bolt and locknut.

Am I the only one that finds a stock CalVin to be a beautiful bike. The tube steel wheels give it the vintage look it should have.
So I'm going to refrain from saying more cause momma said if ya can't say anything nice do t say anything at all!

And yes I do understand a few small changes like better seat and taller shield.

like I said, if I could have found a front wire wheel in tubeles for a reasonable price, it would have gone on. as it is I had the lester mag sitting in my garage, and it fit. The rear is still wire (although now tubeless) and I'll continue to try and find a matching front.

I don't have a problem with tube-type wheels, either. Tubeless is nice for lighter weight and such, but the ease of flat repair part is really not a whole lot different from one to another. I guess its all about what makes you comfortable...

I think the Lester mag looks better than the Guzzi tubeless spoked wheels, for some reason those have always looked just a bit wonky to me.
Don't take anything I say about a CalVin to personal, I'm just a diehard lover of a stock one. Beauty over function is my personal choice on this particular bike. Love mine and have fun with yours!

Cwizeman I'm with you mines all stock the seat is fine for me. but I see that as a very personal thing....

    could we go over the oil filter change mine was serviced by the dealer I've got 1 oil change under my belt. I have the realgaskets silicone pan gasket an I have some oil dripping from the 4 bolts not the pan gasket so did I miss something maybe a little sealer on the threads or what. an this did not show up right away.. I looked on a parts diagram no orings or anything I could see.

    I'm working 13hr shifts got married an bought a new house very busy an my calvin dripping is not what i want to see. Dan

hmmm, never had a drip from the 4 internal bolts of a pan. You have a leak and you are using a non-oem oil pan gasket? I'd go back to an OEM pan gasket then.

gasket had tabs or extensions that extend inward from periphery in order to seal the areas under the two pairs of long bolts.

The front had an interesting twist. When I examined the OEM front wheel, I assumed that the factory used the same front wire wheel hub that had been using since the first front disc brakes bikes since 1974. Assuming that I figured that the Lester Mag which is machined to those same specs, and is made to use the standard 300mm rotors/bearing carriers and inter bearing spacer, would be able to use the more modern 320mm rotor/bearing carriers and inter bearing spacer. From this picture, you can see it did work.



 

That wheel looks great on that bike!

I realize I go on and on about how the CalVin doesn't fit me. One would wonder why I continue to own it... Well I'm getting closer to making it comfortable for me.

I have never liked how the brake pedal intruded into the right floorboard space (and was not far enough forward). If I had it adjusted high enough so I could slip my foot under it, operation of the brake became compromised (high latency, imprecise pressure, etc). Today, I had a buddy who is deft at heat and metal straighten out the brake lever. This moves the pedal inboard (and forward slightly). I haven't riden the bike yet, but garage fitment test are all positive. I can put my foot in a natural place on the floor board, and because the pedal is lower, I can easily pivot my foot on the heel to operate the pedal. My buddy did minimal damage to the chrome as well. win win.

Yes, win win. I drove the bike about 100 miles on 7/4 to the local flat track races. my right foot is now free to use the entire floorboard. As a matter of fact it hits the crashbar before my shin hits the more forward right valve cover. I don't think the left side would benifit from a similar mod to the shifter, as the more rearward left cylinder forces the left leg to splay, and moving the forward end of the shifter inboard would be counter productive. What the shifter could benefit from is having either end bent downward. That way both the forwrd and rearward (downshift and upshift) pegs could be closer to the floorboard requiring less lift of the foot to operate...

took my shift lever to my buddy with the torch. we worked some more mojo on it. straightened the dog leg left moving the forward peg inboard, and bent the forward arm downward, allowing me to keep my toe on the floorboard during up shifts and my heel on the board during down shifting. inch by inch I will make this bike fit me...

wanted a backrest to go with the Corbin, but didn't want to spend $200. $13 from ebay. problem is the foam was too thich and pushed me forward. Unzipped the cover, and found the foam could be cut with a hacksaw. Carved it in two front to back, and placed the carved off piece behind the post and wood frame. Zipped the cover back on and it is now perfect...

    Hello all  this is about the calvin windshield. I'll just get to the point I think the owners of a calvin will see it an if for them might try it.

I took the top mounting bolts out the one that determine the angle our rake of the windshield, moved the windshield back at the top increasing the angle or getting the top of the windshield closer to my nose and drilled new holes I hade to remove the windshield itself to do this. maybe with a small drill or angle head this would not need to be done.

     I had trouble seeing over my windshield which was my biggest complaint and as a benefit I'm in cleaner an quieter air. now that I have done it I may try some more.  so an option I have not seen anybody talk about before looks very natural. Dan
