Cliff, Thank-you...My seat pan is roughly the same length as your's..(my research has shown the possability of as many as 3 different pans ) and was hesitant to bitch w/out knowing if I had a "proper pan" for the Duck tail...At least now I know I'm once again in search of a "cover". Fortunatly I've some experiance w/foam (shaping etc) from my own projects, & have re-covered many ATV/Dirt bike/PWC seats at work. Thanks again for taking the time. G

Wayne, obviously your' no "neophite"  and am hesitant to add. but main bearings sizes were/are determined by both case & crank demensions. Having case markings put you 1 step ahead of most. as these were the first to "dis-appear" (generally before the "magic marker" colors on the bearings themselves). crank sizes (both rod & main) were usually etched on the inside of the crank flyweights at cam chain. read left to right, 5 digits main, 4 digits rod. with a chart in the shop man to derive size/color..comparing case to crank clearances. Striations due to passing "debris"thru bearing are generally of little consequence, but any apperance of "copper" should be addressed. some "300" main bearins are NLA, but have been superceded to 422 or 425  (I think) at any rate plasitiguage doesn't lie. unless easily discernable damage has been done, My concern would be the maintaining of oil pressure  which after failed oil pumps/blockage falls upon wiped plane bearings. watching w/intrest, G

Also possible, weep from cam chain tensioner, either at gasket or from tensioner rod passage. Tip, locating oil leaks when oil is new & "clear" can be difficult, especially for those of us with "poor vision". Powdered deoderants & arisol foot sprays show "snail trails" which are much easier to read, & are easy to clean. Luck g

A little help please. I have 2 sets of gas tank emblems. 1 set is in sittu  on  what I believe to be an un-molested  K1 tank,(non-wrinkle. r/h cock, 4 nickel, ruby red, painted  stripe,) It has "zits" between the letters. and the letters are filled in white... The 2nd set,  of unknown year tho OE, has "dimples" within letters, smooth bridges between letters, and also has white paint within letters. the mounting posts correspond with my "recent aquisition" wrinkle tank.the "bases" of all emblems are silver. In reading previous posts, there is a note that a posted pic.is incorrect tho it has "dimples " within letters...& a reference (lost) to yami. for correct.. What am I missing ? Can I "paint" my "lettered dimples' emblems in black  and "Detail/strip" the chrome outlines, ? or is there anouther  configuration out there. Thanks in advance,, G

OK,  Fairy Tales all start out "once upon a time".  & Sea stories "Now this ain't no shit". This is neither,  just the story of my Sand cast. which you may or not believe/or find entertaining... In the summer of 1983 a much younger Gane was working as Parts Mgr in a long since defuct Honda dealership when a gent came in complaining of a "bottom end rattle" in a rather "rough" 1970 CB750. The Service Mgr. ( a close friend to this day ) attempted to explain that the rattle was a combination of primary chain & clutch noise which were "charactaristic" to the  beast & nothing to be concerned about.... Apparently this didn't appease the gent, & He went "up front" to see what kind of trade -in the shop would offer. It must not have been much, As the Service manager "Andy" Wound up with the bike & title. Fast forward a couple years, "Andy" is offered a position w HONDA  & has to move to Gardena for "training & position as "tech ref". & sells me a "Dead" Dodge van & its contents... Forgive, but I've no recall of the amount but it was "minimal" I was an aptmnt dweller at at the time & parked the van at my parents place until they started making "threats".... a starter & head gasket  (no fun) finally made the "highway star" sell able, & I did. & "broke even"... Inside  the van was a hodge podge of parts, & "most" of what is now the 1400.   Like most, I knew that a "rough cast" 750 eng. was worth holding on to, but figured a '70 titled bike was "simply early" & nothing special. As a result, as the notion struck me, I "pieced together"  the bike with whatever I had at hand ,& rode. Now. some 26+  year s  later I realize this machine has "intrensic value" & that over the years, I've "pulled numerous "boners". The most notable, "buying a "flat seat" (cause it fit), & hardware was right, & swapping fork s because I couldn't find correct seals. & the rust was beyond salvage. Because I was "ignorant" I focused my "parts searches with parts which were "period correct" rather than "true", As a result, my "scattered bike " is probly worth less than most " garage finds" . where the parts were "correct if "wasted". Still, knowledge is a tool.".. I've no plans to "show" this bike, or even to sell..It's like family.   My  "quest for this year was to achive proper paint. Unfortunatly "wrinlkle" tanks seem to be scarce, & THE 2 tanks I'd thought might qualify are dudds. STILL. I have an "honest" sandcast  frame & engine.  airbox is two hole w/out conture. exhaust  is 3 '300  & # 4 un stamped. anyone with a  salvagable wrinkle tank and or a 300# 4 pipe pls PM me, My object is not for "concourse"bike. Just a "consistant" period piece. I ride  this  bike..Abettt 4-500 miles a year,  my story is basicly one of neglect & ignorance,  still, I have good intentions, & hope that this winter I'll have the time & funds to have a much more "presentable" bike. as usual G

All, thanks again for your grace,, I'll try to do a wet sand of my " frame #" & take pic's of it & "eng #" this weekend, & see what y'all think. as usual G

Sorry, If i'm posting in the wrong area, where would be more apropriate? also, I should have posted the Vin of my bike. it is cb750100114. but your' responses have already helped. At least I now know I need to continue shopping for a tank w/ wrinkles visable thru cap opening. Another question please, I have looked at both the frame neck and engine upper case, but can find no date of manufacture. and looked thru the list of options & see no list of vin #'s with production dates. does such a thing exist ? because of the "brevity" of the vin's on these bikes I'm assuming there is no way to reference original color. in reading, it seems the candy ruby red was the most popular, and my personal favorite. my title is dated 1980,  so I know I'm at least the 2nd owner & possibly many more. I appreciate your' pacience, thanks g

Gents, Thanks for the welcome..KP you are correct sir... as well as the 1400 bike, I have a K-6 which I bought  new, & has seen a couple mods, and a KZ1000 A1 which I  consider a "period piece".G
