Im beginning my first build on a 79 gs750. The main problem I'm running in to is my forks. When I got the bike their were no brakes on front. I have dual disc set up however I don't have enough room between my forks for speedo, both rotors and caliper without hitting the forks the calipers don't even begin to fit. Do I have the wrong forks, triple tree? Thanks in advance
The cruiser did. No telling what is missing off that front end - spacers between the wheel and fork, the axle looks too short, triples could be wrong. No way of telling what kind of mess the previous owner made out of it. Also looks like your right side rotor is not snug to the wheel? You can look at the parts diagrams for this bike here:
Yeah I thought that was weird as well. The guy I bought it from had the leading axle forks on the bike, but had 1 "bottom mount" fork with the bike sorry don't know the proper name
The lowest part of the forks is called the lower fork leg, the shiny tube that it slides on is called the fork stanchion tube.
Leading axle means the axle is located towards the front side of the lower fork leg and not directly at the bottom of it, as it really should be on that model bike.
From these initial photos it's beginning to look like you have purchased a Bitsa (bits of this and bits of that) It is fitted with what appears to be a stock original front tire that has become as hard as a fossil with age and a predominance of flat black paint combined with your saying the bike had no front brake makes me think you bought somebody else's unfinished abortion.
TrialRider: The GS750L did have leading axle forks.
Neil: Jack the front up in the air and remove the wheel. Loosen the triple clamps on one side so you can spin the fork stancion tube around. As you spin it, watch the bottom of the fork to see if it moves in in a circle, or stays in one spot and spins....you are looking to see if the fork stancion is bent. Tighten it up and repeat on the other fork.
Also, Show a pic of your calipers. If you look at my 550, you can see that the disc is also very close to the forks. Something else may be wrong in your inventory.
Yeah thats really close, I had a similar issue recently.. my calipers to get the disc to sit central in the caliper meant the caliper hit the rim spokes.
Your issue will be the caliper and lining up with the disc.. I sold mine with some disc spacers, and shims on the caliper mounts.. its tight but they work a treat.
Thanks for all the responses, I was able to find the correct forks locally. Put the new forks on and all fits perfect.
