    @Cycle Goon , I knew you were joking :)

    The chrome tank trim arrived yesterday, it just makes the awesome tank look even more awesome:

    Fantastic, fueling my want for a project... although my mechanical skills lack to say the least. What is the process/product you use to get such a good polish on the metal? Looks great.

    It is incredible the wheels on my ct90 looked like junk when he got the bike.
    Oh and man it runs great, it started yesterday when my 1150 would not.

    The last step is to use this stuff:
    [​IMG]
    The chrome usually cleans up good with WD40 applied to a 0000 steel wool pad.

    The aluminum parts usually have some kind of a clear coat on them that must be removed with a good paint stripper before you start sanding with progressively finer grits of sandpaper from 400 - 2000 grit. Lots of elbow grease. Then the final polish is using a 6" cloth wheel with White Diamond.

    In the past I've used a fine crimped wire wheel as a first step after stripping any remaining clear coat. This can easily be overdone, resulting in gouge marks that have to be removed with coarser grit sandpaper.

    With regards to engine work, the current plan is to send out the head, intake manifolds and cylinders for Hondaman, to work his magic on. Hondaman, AKA Mark Paris, is the author of this book:
    [​IMG]
    and somewhat of a celebrity in the SOHC/4 community. In my communications with Mark, he explained to me that intake restrictions are the most significant performance restriction in the SOHC 500/550 motors. The best way to improve the breathing to port the head and intake manifolds, slow down the spark curve rate and change out the OEM cam for one with longer duration. Mark recommended the Megacycle 126-00 or 126-01 because it is longer in duration with lift similar to stock which increases flow and performance without putting more stress on the valve train. The Megacycle cams are not cheap ($450) but in Mark's opinion they are worth it.

    I got extremely lucky last week - Just before getting in touch with MegaCycle to place my order, My daily search on ebay (CB550, used, Honda) popped up with a Megacycle 126-01 cam selling for $125 including shipping! I snapped it up immediately. It has arrived in perfect condition with the original box including installation instructions, timing card and a small container of Red Line Assembly Lube!

    Now that is a pretty good deal! Before I install this cam I'll have the top end work done by Mark.

    I also found a NOS Connecticut Luggage rack for the 550 upon which I can mount the Arthur Fulmer top box:
    [​IMG]
    While it mostly fits, it seems to be for an older model CB550 because the mounting holes to attach it to the grab bar are not in the proper location for my 74:
    [​IMG]
    I think that I can remedy this however, using a corner bracket of some sort.
    Here's the top box sitting on the rack - not yet hard mounted.

    Lots more left to do!

    I'd start with removing that atrocity directly behind the seat and that hideous thing adorning it. It absolutely kills the lines of an otherwise beautiful bike
