Restore, daily driver, or sell?

[markusarealuis]

Alright - I have searched and searched both this website and BassCliff's site to try and get the stock tire numbers. I went to BassCliff's owners manual and then used the tire web link his site provides and made the conversion. However here is what I have and I know this cannot be correct; since my rims appear to the same size circumference.

The manual BassCliff provided for GS750T says the tire sizes are:
Front 3.50 H 19 4PR
Rear 4.50 H 17 4PR

Conversion per the Tire web link on BassCliff's site yields:
Front 100/90 19
Rear 120/90 17

All I want to do is replace the dang tires with the factory specified sizes. I have no idea what the previous owner might have thrown on there - his handy work is still causing me grief. I do not want to add a bigger rear tire; I do not want to change the handling, etc. Each time I search on here I have dozens of threads referencing the above but i can't seem to locate one person saying what the factory tires are -- Please help.

Thanks,
Markus

If that's what you're looking for I guess you'll need to find someone who still makes tires in inch sizes.

Just for grins, I have 100/90-19 and 120/90-18's on my 1978 CB750F. That's the closest 'metric' equivalent I found to what came on it from the factory.

I don't need them in inch sizes merely want close to what was stock - jeesh..... BTW - trade me your 78 CB750F for the GS750L....does yours have the black motor? I like those with the beeping turn signals ...

Yes it has the black motor.

Dang I just go called a "lady". How are your valve guides holding up. I had the exact model and had an issue with mine. I loved that bike and shouldn't have sold it - oh well I have a great "ladies" bike here to tinker with currently. Anyways, back to tire size, will the below sizes get me pretty close to the stock sizes?
FRT - 100/90 19
Rear - 120/90 17

Front

rear
130/90-16 67H

No, the bike got called a 'Ladies model' you just ride it.

The base gasket is leaking on it. For now it's on the back burner and yes, I'll be checking the valve guides while it's apart.

You can look at the parts fiches
buying tires? well, I warned you. You are commited to wearing them out now....I looked at your pictures linked in your profile and the ones you have on now look ok, so just replace them with the same size unless they are obviously rubbing on the swing arm...and watch out if considering a wider or taller tire per the swingarm... It can be a little difficult to find exact replacements per the book and not much choice unless you spend big bucks especially as a pair.Cheapest may be to mixnmatch among the less-pricey manufacturers to get the sizes ....the rim size you have should be seen on the rim.
Using the parts fiches from BassCliff's site I have it as:
GS750LN
Front 3.25-19" IRC or Dunlop
Rear 4.5 H19 IRC or Dunlop

You have that right. Lots of people use 130 on the back, because it is more available. I think the bike steers better and is more neutral with the 120. 130 is fine though.
