Oil Filter / Oil Pan schematic Honda Cb350f1 Four (u.s.a.)

These super little Honda's were groundbreaking when launched in the early (350) and mid (400) 'Seventies. As a classic they are as revered as much as any Honda from this or any other period. When re-building or restoring one of these delightful little multi's, you probably would not consider using anything other than genuine Honda parts? Good decision, make sure you use genuine Honda gaskets as well, and leave old British bikes to maintain their reputation for oil leaks!

Damage and corrosion prone casting. This is one of the sweetest of the CB Four genre - not the fastest perhaps but the smooth turbine like performance is just a delight - don't spoil the pretty engine with a sub standard oil filter housing!

There are many after-market oil filter elements produced by various manufacturers, some will be O.K, some may not. If you order a genuine Honda part, you know it will be right. Saving the odd Euro may cost an awful lot more in the long term, if your filter breaks up, or clogs up causing oil starvation.
Before you place your order, why not check our online catalogue for other vital service items, or with many machines, you could browse the ever expanding online 'parts list' fiche. This will help you find the parts you may have overlooked for a successful service or overhaul.

Essential to replace this 'O' ring when removing and replacing the oil filter - With a new genuine Honda item preferably!

Your overhaul will be easier to execute and with a more professional outcome when you specify new genuine Honda parts like this DRAIN SCREW. One of the first items to show the stress and strains of poor mechanical aptitude - Usually over tightened, and then chiselled into submission!
