thanks again guys this forum is by far the best i have ever been on you guys have been a great help i will be posting my build up in the next little bit in the project section

 a couple more questions my tank is rusty on the inside anyone had anyluck with the eletrolosys method? and after the tank is cleaned out do i need to line it? if so what should i use

lastly there is a spare motor for sale in my area. the problem is that the guy has no idea what year it is just that the case says CBBBBB will any year 350F motor fit my bike or will i run into issues(my bikes owner ship sais 74 but was manufactured late 73)?
he wants 150 for it he sais when he bought it it was running but it has sat for 8 years does this sound like a good deal i have no idea what a spare engine is worth but some spare parts would put my mind at ease? what do you think (any of you know of anybody selling a parts bike)

thanks again guys

Not sure about the motor, but to clean the tank you can either use a tank lining kit like POR15 or you can just use a strong toilet bowl cleaner to remove the rust and then jsut run it. I used a toilet bowl cleaner that was 27% hydrochloric acid, worked awesome and it doesnt take long at all, i wouldnt sugest it straight though i would dilute it some. good luck

Any Honda CB350F motor should fit just fine.  I have used POR-15 on several tanks and am very happy with the long term benefits of their system for cleaning and sealing the fuel tanks.

Any 350F motor will fit in your bike  But the 'CBBBBB' written on the case is likely the bearing code stamps on the back......which have little relation to the bearings inside for some reason (another thread) 

On the upper case behind the cylinders is a place with the engine serial number which should read 'CB350F-XXXXXX...'

It's handy to have a spare engine around when you need parts, and if you have the cash $150 sounds alright to me. I had a spare engine when I did my restoration and used quite a few parts off of it despite having a perfectly good motor to work with.
