Mashermoto's big street tracker adventure

[mashermoto]

Otto,

Sorry about the late reply...I haven't been back here much since the weather turned cold, holidays came around, and college football bowls started. Man...first it was Boise State that blew my Oklahoma Sooners out...now West Virginia. Stink

Anyway...life goes on.

To answer your question, Pete found that coil for me. Just happened to be on sale also ;D

Here is the link:

Cycle-rama was pretty good to me. The coil and hardware is great.

Thanks for the comments.

BTW, I don't mind helping with the crank rebuild, but if you want the real expert, check in with CrazyPJ. That guy knows it

[mashermoto]

Hey thanks Gary...haven't heard from you in a while.

I've thought about using those stainless lines. I'll give Galfer's a look.

Later.

[stevesemti]

Hey Masher, really enjoyed your story, and anxiously await more, but you never mentioned, here at least, what welder you ended up going with...just curious!

[50gary]

Welders come in Blue or Red, I have a Blue one.
By the way, being a frustrated editor (note that spelling) the welder is the machine and the weldor is the man operating the machine.
Cheers, 50gary

[jeremy]

hey, mine is black
the parts are white and it has a blue gun.

[mashermoto]

Steve,

The welder is from Harbor Freight. They had a whole pile of them stacked up at a tool sale last year. I bought that one for $99. I had a friend who owns a welding shop get me started and now I can't live with out one. It really opens up the possibilities.

Because it is such a low end unit I did purchase a three year warranty for about $27 extra. If anything goes wrong I just take it back. So far no problems.

If you are a weekend warrior like me, these el cheapo units seem to be ok. But I wouldn't recommend one for a person making a living using one

I've got some more work to post. I'll get the pictures up soon.

Later.

[mashermoto]

Here is some more progress pictures...



This is my seat after having a few modification made. I had a place called Superior Interiors put a new cover on it. I used the perforated stuff on top and cow grain stuff on the sides. Also notice the seat lock cover I fiberglassed on the side.



I find the seat pad looks much better when the back curves along the lines of the tail section. The purpose of the fiberglass work is to hide the seat lock mechanism and protect it from the elements.



Here is a modification I made to the seat pan. I epoxied three threaded fasteners to the fiberglass. Thanks to Ace Hardware I was able to get them with metric threads ;D



Two of them bolt through the existing holes originally used to let the OEM seat foam breath. The third is up front.



Here are my wheels after polishing the rims and painting the rest.



Except for routing the throttle cable and front brake lite cable, the front end is finished. The XS100 calipers are rebuilt and a new tire is mounted. In case you are wondering, the tires are Dunlop GT501. One thing you can say about Dunlop is that they make tires in just about any size.

I now wish I had bought 110/90-19 or even 120/90-19. The 100/90-19 I did buy is OK, but I really wanted some more beef up front. The discontinued Dunlop K591F I replaced was all that would fit between the forks. It was a 100/90-19. I wish these tire makers could find a more consistent way to brand tire sizes



This is the rear tire mounted on a SR500 wheel. I replaced the bearings with All Balls stuff. The original sprocket was a 44 tooth and has been replaced with a 40 tooth from Sprocket Specialists. They have good quality sprockets...at least it better be for 73 bucks

With a 18 tooth counter sprocket, 40 tooth rear sprocket and a overdrive 5th gear...I have no idea how this bike is going perform But I don't intend to use it as a long haul road bike. It should be real fun running through the gears



The other side mounts the XS1100 rear break setup.

Right now my biggest hold up is getting a dust cover and spacer for the SR500 wheel. It's been on order for two weeks After I finish mounting the rear wheel so that it will stand on its own I can mount the exhaust pipes and try to fire it up for the first time.

I think Pamcopete has been waiting since November for me to see how his ignition design works out It should happen soon

See Yaaaaaa!

[mashermoto]

Hello again ladies and gents.



Well...Pete doesn't have to wait any longer to see if that 277 re-phase ignition he designed will work...because it does ;D



I got the pipes and other goodies mounted up this weekend, which allowed me to concentrate on the ignition system. It's all dialed in now and the time is nearing when ol' Masher finally gets to go on that first test drive ;D Man does this engine grab RPMs quick

So what is left? Well the carbs need some attention...that will be next. The brakes need to be bleed. The forks need some oil and air. A few minor adjustments here and there and it's time to go terrorize my neighborhood.

Once all the kinks are worked out I'll show you what I have planned for the paint scheme.

I should be back soon...so stayed tuned

[pamcopete]

That bike is awesome! But, it certainly doesn't look factory! (the details do) Where's the "You Tube" video so we can hear her run?

Of course, I'm curious about your procedure to "dial in" the ignition system.

[mashermoto]

Good to hear from you again Pete ;D

The dial in wasn't that bad. I basically loosened the screw holding the timing disc then moved the disc around by trial and error. I checked the timing with a light. The disc slots are filed close enough that setting the timing on one cylinder does the job for the other. It's like you said...once you get the timing set...you don't have to set it again

Since you asked...I'll post some pictures and provide a little more detail on this post and the 277 ignition post.

I'm having some trouble with an unstable idle, but that issues doesn't have anything to do with the ignition. I just finished reading Griz's carb post and I believe I can get the idle to settle down by adjusting the mixture setting. It was initially set at 2-2.5 turns out

I'll put something out after I get the carbs dialed in.

BTW, I'll have to do the You Tube thing...that is after I figure out how to post a video It will be fun to hear how quick this engine revs

Later

[Cooltouch]

mashermoto,

We 277 aspirants wait with bated breath. Really wanna see a video on Youtube.

Best,

Michael

[5twins]

Very, very nice. Is that Mike's Ascot exhaust? I heard they don't fit up all that well. Did it take major tweaking to get it on there? It appears you cut the kickups off the ends of the headpipes so the mufflers run straight? I really like the look of the headpipes.

[mrriggs]

How is the gearing? What rpm are you spinning in top gear?

[pamcopete]

mashermoto

Here's an Excel spreadsheet that solves for RPM vs MPH vs sprocket ratio. I added the 40 tooth sprocket to the pull down.


www.amckayltd.com/xs650revs.xls

Front 18 T
Rear 40 T
Rolling distance 78.5" (18" tire)
4574 RPM @ 60 MPH (standard 5th gear)
4383 RPM @ 60 MPH (Mikes 5th gear)

Mark the rear sidewall and roll the bike one revolution of the rear wheel to get your rolling distance for a more accurate calculation.

If you want to restore stock RPM vs MPH, then install a 36 tooth rear sprocket.

Front 18 T
Rear 36 T
Rolling distance 78.5" (18" tire)
4143 RPM @ 60 MPH (standard 5th gear)
3970 RPM @ 60 MPH (Mikes 5th gear)

[mashermoto]

I posted the timing procedure for the ignition on the 277 ignition post. You can see it here:

xs650temp.proboards29.com/index.cgi?action=display&board=ID&thread=1173886314&page=10

Cooltouch, I got the idle situation worked out, but not how to post on You Tube yet But I will get around to it. I can tell right off that I need to change out the pilot jet because it idles best with the mixture screws at about 1/2 a turn or less out. That's right in the range where the jet needs to be changed.

5T, I don't know who made the pipes. Burge offered them to me last year when I started this project. I cut the headers off at 32 inches, tweaked the left cylinder header by hand to cross under the frame a little better and somehow everything lined up perfect The original fitting just wouldn't fit right and I liked the looks of the shortened mufflers better than the long up swept look. They sound great. Kinda mellow...not too loud and not too soft.

Riggs and Pete, I don't know exactly how the gearing is going to work out. I stepped the counter shaft sprocket up to an 18 tooth, but the smallest rear sprocket available for the SR500 rear wheel is the 40 tooth that is mounted. According to Pete's calculations the combination has a little more RPM than stock. Because this is my short range hot rod bike, 1st through 4th should be fun around town, but 5th gear will probably have more buzz than I would like even with the overdrive. I'll have to wait and see

I'm really down to finishing a few loose ends then I can go for a test drive. I got the front brakes bleed tonight, but the rear disc is giving me some grief. I can't get it to pump fluid But I'm sure there is a post on here somewhere to get me through it ;D
