"new" Yamaha xs750 project

Thanks, jugernaut, that helps a lot. Did some more work on the bike. Pulled off the swingarm, couldn't get the driveshaft out though. If anyone has any knowledge on this id appreciate it. Also, I'm having trouble witht the wheel bearings. They are stuck and I can't figure out a way to get them out. Any help would be appreciated.
 
I tried pulling the driveshaft out the other day, looked it up online, and came to the conclusion that its essentially not worth the headache. Theres like 4 circlips, a metal shield you have to bend back, and a u-joint that needs unclipping. I'm just going to mask both ends, wire wheel mine, and spray it with etching primer and grill paint. That should give a finish pretty close to powdercoating as far as durability is concerned.

It could end that way, as there is a seal on the shaft that is not readily available. ;)
 
Cool, so don't take out the driveshaft. Easy enough! What about the wheel bearings? Do you just piund them out? I'm replacing them... :eek:
 
Do you have a manual ? there are 3 bearings in the rear wheel. The spacer makes it a little tricky, so take some time to familiarize yourself with all the parts. Patience, not pounding. ;)

I agree with this. I pounded mine out and messed up the rear wheel bearing spacer. I left the part out b/c a new one was no where to be found. It does make putting the axle in a pain in the ass. Use a large pipe the same diameter as the outer bearing race and freeze them before putting back in. If you can rent a blind bearing puller do it. Buying them is expensive.
 
Ok, more work done. Got the head off!! that was alot easier than I anticipated...hopefully I didint just jinx myself. Got my new seat, and a whole bunch of bearings that I ordered. I'll try and find a blind bearing puller to rent out and get those bearings, thanks for the suggestion, juggernaut. If anyone knows any info on what to look for on the trans as far as preventative maintanence, I'd appreciate it. Already asked on the triples forums, just casting a wide net. Pretty stoked at the sight of the pistons, makes me feel I'm almost there, as far as disassembly goes. Next, I hope to get the engine out of the frame, split the cases, clean everything up, and send the block and frame out for sandblasting. When their out, prob start on rebuilding the forks and find some upgraded shocks. Anyone use progressives for a Harley Sportster??? They fit my bike, thinking of giving them a try. Thanks for any and all words.
 
Yeah, I'm pretty sold on the progressive springs for the front forks 8) What about the rear shocks? That was what I was thinking of replacing with the shocks from a sportster.
 
Probably not a big difference from stock. Just make sure they are eye to eye and the same length. I would think that they would provide a more cushioned ride compared to other shocks. I really don't know. Also you shouldn't be putting that HD crap on your beautiful Yam. ;D

Be careful with these guys. They charge your card and don't tell you if an item is back ordered. Call first. Their parts are good though.

So I got the cylinnders off, pistons and sleeves look like their in great shape. Having trouble getting the oil pan off though...still haven't heard from anyone off the triples site on preventative procedures on the trans. Ordered some caliper rebuild kits, new master cylinder and got the paint. Its all slowly coming together. ;D
 
You would benefit from a blind bearing slide hammer puller. I bought all new bearings for my 77 and it was recommended to me to get one. Also the drive shaft(with swingarm already removed) will pop right out. Its a splined shaft. I removed mine when painting the swingarm.
 
Cool, I'll try pulling out the driveshaft again I guess. Got the oil pan off and the engine on my bench, almost completely torn down, just need to get a puller for the alt rotor. After that I can split the cases and get the thing sandblasted so I can paint it and start piecing everything back together. Frame is prepped and ready for blasting, should be taking it down there today if it doesn't rain! Suspension rebuild and wheel bearings and tires are next. Got a puller for the bearings at harbor freight, hopefully it works, otherwise I'll be getting a slide hammer like you suggested. Got any reccommendations on tires?
 
I like the look of the Firestone Deluxe Champions. Expensive but they really make the older bikes pop! Jugg any more recent pics?
 
Here's the latest update, finally got my gasket set. So I took off the alt/rotor assembly and tore down the clutch to check the layshaftbolt which is notoriously troublesome on these triples. Everything looked good, smooth and lubricated, no chunks of metal. Measured the springs, pads and plates, all good. Pretty amazing since I think it had been sitting outside for God jnows how long. Got the frame and gas tank painted, will upload pics as soon as I can. Getting some more stuff to the sandblasters tomorrow. Opening day tomorrow at Angels Stadium!
 
so....screwed up on the rebuild. Snapped off some crankcase bolts while tightening to final torque :'( . So now, I'm going to have someone else rebuild the whole thing. At least it will come with a warranty. Been busy ordering all the stuff to rebuild the forks and painting. Finished painting the tank, frame, and all the frame parts eg. swingarm, headlight, triple clamp, etc. Just got my new tires and tubes in. Bridgestone Spitfires, looking pretty sweet 8) . Just need to get my rims blasted and powder coated and then I'll have a rolling frame. Just waiting on the engine now.... anyone know where I can order some seat padding/covering material? The site I got the seat from is kind of steep in price for a seat cover.
 
Its been awhile since I posted. Got ALOT of work done. First, got some new tires/tubes and had wheels stripped and powdercoated. Forks rebuilt with new seals and progressive springs. Finished painting (I hope, something always seems to pop up) all parts that should be painted. Got new rear progressive shocks and springs, they are for Harley Sportsters, I am a little bigger than the average rider, so I think they should be spot on for my size and improved handling. Finally got everything all put together today, so now I have a roller bike! You can see it in the pic I posted on my flickr account. I'm super excited right now, but I still have the Engine, Wiring, Exhaust and Brakes to deal with before I can start her up. Roommate is leaving too, so I'll have to put the bike on hold for the moment, but at least I can finally roughly see what she'll look like.
 
Nice. I just put my engine in last night and will have several paint touch ups on the frame. The bike fell over a couple times and scratched one of the gauges. So now a strip and repaint is in order for a few things. Seems like I'm painting everything twice.

My recommendations for you: Install the engine in the left side. The drive shaft coupler on the engine should be taken out to make putting the engine in easier. Don't forget about the drive shaft boot. (Don't ask)

With the harley shocks, did your slide right on or are the holes a little bigger? I got Progressive 412 13.5" from ebay and the bushings are about 2mm too big. So 'll need to figure out a way to shim them. Good luck with everything and post up some pics!
