Did you end up getting the new battery? Isn't it a first step to locate the battery, and then attack the seat project?

I did not get a battery, I'm actually thinking of running the one I have for this season with a temporary bracket. I have the perfect mounting spot and idea ( I think ) just to be able to run it for this season to make sure the engine, transmission and brakes are all mechanically sound before going too heavily in modifications. The motor ran fine and what not but there is still an unkown. So my new goal for the bike is to get it street worthy for this season and then modify it. Why modify a bike that isn't 100%?


So the list as of now:
Acquire carbs, exhaust, sprockets, chain, and pods
Rebuild forks ( Still need fork bolts )
Brakes
Front wheel/new tire at least
Rear shocks
Lighting
Handlebars

You're getting it right man, get that thing on the street and cruising, then mod for performance/looks (performance > looks)

Is good the way you're thinking now.



Now let's talk about your future plans for the bike:

Carbs/pods: As suggested earlier, I wouldn't run pods, unless you are CERTAIN that the pods/carbs combo are "easily" tunable. If you state that the bike ran relatively good, why introduce a new variable to fiddle with in order to make the bike run good to ride it? I'd suggest you get the stock airbox as it would make the bike perform at it's best, with the minimum effort.

Rear shocks: have you decided yet? Those CL moto tech shock look the bomb, and by looking at the Webpage and the way Chris explains his work, you can almost blindly assure he knows his shit. And for that price, I think is hard to beat.

Lighting: what ideas have you come with for this?

Handlebars?

I don't want to say this in a rough way, but I think you bike would look way way better if you cleaned those welds you did over the top subframe where the new tubes join the stock ones. Just behind the rear tank base. I think that finish is lacking some time on it.

Anyway bro, keep on it man, try not to rush it and the outcome should be very good.

Yeah I think I am making the right choice by making sure everything is 100% mechanically. Plus, I don't have a ton of riding experience and the last thing I want to do is sink a ton of money into powder, paint and make it all look nice and ride it without knowing how it handles or rides whatsoever.

As for the carbs, I am purchasing a set of ZX600 carbs with pods, extra jets and an exhaust from a member on here. My stock airbox crumbled when I removed it. I am definitely going to go with Chris's shocks. We are in contact and determining the details. Handlebars will most likely be superbike bars. Also being purchased from a member on here, hopefully.

Yeah, the welds could be cleaned up and will be before powder but that won't be until next winter. Like I said, aesthetics are at the bottom of the list right now. Thanks for the input!
 
Sounds like you're in good shape and moving in the right direction. Just hope those shocks are stiff enough & long enough that you don't have frame issues.

Me too. I think Chris has a good idea with what to do to avoid that though. I'm excited to see what he comes up with actually.
 
Seats finished, the pictures make it look pointy and weird but it actually fits great! The tank will be painted white by the way.


 
I did some small work today. I mocked up my battery tray idea and it turned out great. Laid it out on some sheet steel and started cutting as much as I could until I take it into school to cut and bend it on the shear and brake. I am trying to take all the sheared off exhaust studs out and got all but one out. There is about an inch or so sticking out and no matter how much heat or penetrating oil I throw at it, it won't budge. So tomorrow I think I am going to weld a nut on it and try that. I also trimmed down the front fender a little bit.

Took a look at the front brakes and this is what I have:





Do those pads need replaced? They look really meaty but they have been sitting. Not sure if time is a factor with brake pads. Does the master need rebuilt or do I need a new master? When I rolled the bike into the garage, it had barely any brakes. Would this be due to super low fluid or a bad master?
 
If it's me, old stuff get replaced if even close to sketchy. So, yes. your pads look meaty but if as you say, they've been sitting, what another 15$ bucks to change them?

I'll add them to the list. Today I scored a set of new old stock JT sprockets for cheap as well as a set of non air fork nuts so I can rebuild the forks, finally. Unfortunately the one last stud I needed to get out sheared off in the head. So it looks like I'm drilling and tapping. Great.
 
Please dont. Lay a nut over the stud, even if it is flush with the head, and weld it through the hole in the nut. If you cant do it, take it to someone who can. The heat from welding will release the stud and the nut allows a wrench to turn it out. Far superior to drilling.

What about using a left hand bit that's smaller than the bolt?
 
I'd try the above. If all else fails, the drilling and tapping as last, LAST, resort

I tried drilling it with a left hand bit but stopped in fear of doing more bad than good. It still didn't budge.

I already did that when there was a half an inch still sticking out. Even let some penetrating oil soak in after welding the nut on. I slowly turned and it just sheared off a few mm into the head so it's not flush.

Ahh shit. Looks like its drilling it out then. Good luck!

Thanks, I'm gonna need it. I just picked up an extracter bit and a tap I'm going to try that first and then go to a timesert if all else fails.

What's everyone's take on chains? Non-O-ring, O-ring, X-ring?
 
So the motor is going to a place that repairs and restores old Porsches to get a timesert inserted in to the head for the exhaust stud.

I still need to get a chain. I need a 530 x 104 chain but don't know if I should invest in an O-ring or X-ring chain. I know you get what you pay for, but I don't need anything fancy top of the line level or low end crap either. Recommendations?
