750 barn stormer
« on: August 10, 2013, 11:46:39 AM »
here is my 78. my plans are a 836cc get kit, dual disk, re gear, good shocks & front springs. i was planning on leaving it stock but every time i looked at it, i felt disappointed that it wasn't a 76 back orange one. then it decided to eat a cam and cam tower. so here we are. right now it looks like someone built a log cabin on the back. hopefully that will change.

lol...sounds like you got the right idea with the looks and engine.  Don't forget about the handling department!  It is one of the funnest things to improve on these bikes because it's relatively cheap and easy and you will really feel the difference!

i am open to any and all suggestions. actually i am hoping to get suggestions. i haven't had a 750Four in years and i'm kinda lost.

another future plan is to lace the hubs to a set of aluminum rims. i need suggestions on size. i also need suggestions on what to do to improve handling.

just keep reading this forum Shawn...it can be as simple as a front fork rebuild with good springs and fork oil to gusseting the frame and   Racetech cartridge emulators.  Good tires are pretty much the ultimate bang for the buck.  Lose weight whenever possible and practical.  Just about any rear shock is better than stock.  Ditch your 17" rear for an 18". Vintage race guys usually go 18" front and rear but that may be a little twitchy on the street.  Swingarm is good to go with a proper rebuild.  Don't make the car guy mistake of lowering the bike and make sure any frame mods are only gonna make it lighter and stronger.  Keep the forks braced, longer rear shocks really sharpen up the turn in, but you will then probly want a steering dampener....

Make sure you get to the root cause of the damage to your cam, not just replacing them.

for sure!! the problem was me... i changed the starter and took it for a test spin... got about 100 yards and the motor locked up. it unlocked when i stopped. so i pushed it home thinking maybe something in the starter or flywheel. well when i bent down to pull the starter i saw the problem... in my hurried state i left the timing chain adjuster out. that was a bone head thing to do. i don't recall how bent  the cam is but the deepest groove is .171

i know i know.... im an idiot

Alternatively, you can do the GL1000 conversion and get the 19" front with an aluminum rim and twin disks, then find a 750A hondamatic rear rim, which will bolt right up and uses the same 17" aluminum rim as the GL, so the front and rear rims will match. The best part is no messing with the rear spokes.

i like that idea. i think i know where to get a 750A wheel. would you believe i gave a friend of mine a gl 1000 last year... >:( oh well.

i think i'm going to call my bike a barn stormer because we don't have any cafes in Tennessee. plus it looks like i built a barn on the back of it.

OK I know it looks bad... kinda resembles a barn. But on the up side a lucus tail light and tag fit perfect into the recess I made on the back.
