Fuel (gas - petrol) Tanks, Side Covers and Air Box / Re: wrinkle tanks
« on: February 22, 2010, 08:18:00 pm »
hi just too confirm what kp has already said
i dont think they made them much later than summer 1970
i have two 1970 cb750 k0's that both had wrinkle tanks vin#15000 and a vin#18000
i also have one 1970 cb750 vin#15000 without a wrinkle tank but im sure this tank is a new replacement and not the original one

i did manage too take the rocker cover off a many years ago after the camshaft seized on me (or started too sieze a sound i will never forget)but it went ok after it cooled down ,so after getting it home decided on the quick fix (remove rocker cover and take a look) after removing all engine mountings and bolts and drop the engine in the frame i finally got the cover off imagine the mess on the cam , the frame was far worse chipped everywhere,the bolts had worked loose so decided too locktight the bolts and away too go,it lasted about a month the same noise partial seizure ,so rather than let it cool i dicided too limp home about five miles limp home is true it snapped the camshaft and bent some valves got home on 2 cylinders,back too the drawing board full strip down rebore piston camshaft and helicoil the bolts,and the frame repowder coated,
job done
so the real answer is NO never dont even think about it,
do it right and it dont need doing again, i still love stripping them engines, but now my back aint up too it anymore

Paint - Badges and Component Refinishing / Re: Candy Blue Green--different shades
« on: February 20, 2010, 02:37:49 pm »
i have a 1970 candy blue green cb750 that the previous owner rebuilt in 1992 with all brand new panels ,tank, air-box,headlamp shell and fork shrouds, i told him i only liked the bike because of its original parts ,he said he was tempted too respray the bike because the shade was slightly different on some of panels (shocking )this was probably down too the parts being sprayed at different times of manufacture and being new old stock ,they could be up too thirty years old or more, cameras dont show the true picture sometimes and sunlight and lighting dont help also, i have picture of three blue green bikes side by side in a bike show and too the eye they looked the same but on camera one had a new tank it was slightly more blue as you know you have trouble in the states with paint bleaching in the sunshine red is notorious for this, and the blue paint will age with time
if you are ever in wales i will show you a real candy-blue green cb750 and a candy ruby-red one

Engine Mechanical / Re: Gasket Installation with Gasket Sealant?
« on: February 19, 2010, 04:11:12 pm »
hi jkulick i have never used gasket cement on new gaskets as the new gasket material will absorb any oil and grease, although i have done on old gaskets e.g. if i change clutch plates ,coat both sides of the gasket and never reuse a head gasket or use gasket cement not worth the hassle .BY THE WAY did you find out the cause of the engine problem in your earlier post, (share the knowledge)and is this the reason for your rebuild now? just curious steve

Engine Mechanical / Re: Engine Smoking Oil from Oil Lines
« on: February 19, 2010, 04:06:13 pm »
i had this problem once with steamy smoke coming from the same engine breather i guessed it was engine back pressure ,new pistons and a rebore cured the problem for me,yours does sound serious might be a piston or rings shot ,you will neeed too strip it at least,

Engine Mechanical / Re: Chain Oiler at Front Sprocket
« on: February 19, 2010, 03:57:41 pm »
hi joe
the best method i have found is to do away with the chain oiler completely and use a bolt the same size and blank it off , as some bikes came with the chain oiler and some without it ,so no worries there ,i have four cb750k0 i think two with oilers and two without , the problem is no matter how far you turn the oil path adjuster as the engine gets hotter the oil gets thinner and more oil will be thrown out on to the chain ,so you have no real control over the oil delivery ,one of my friends took his wife on a long run once only too find when they stopped at thier destination her left shoulder was covered in oil and ruined her white blouse , he swears too this day it never worked but only on that one occasion .lol the moral of the story is wreck your chain and save your marriage ,your choice
bye for now steve

 ;)  i did read somewhere the cb means its a gt (grande tourer )version of that type of model as opposed too cd (deluxe model)but saying that the only real differance is that cb is multi-carbs ,and cd is single carb, i did see this in cb and cd 125s also cb and cd175s
