Mr. Fry,

Since my last post did not help, let me try again! Would you consider going with SS Brake lines? If so, you can get a Banjo directly on the Caliper and forgo the tube entirely. Look to the guys at HEL for help in what you would need for a line from the M/C to the Caliper.

By the way, the rendering of your bike looks awesome. Someone mentioned the resemblence to the '70's Guzzi 750 Sport. Looks like this:

Keep up the great work!

Gersh

thanks again
i'm having a SS line made up right now, we are just having a hard time finding a way to connect it to the caliper (not enough room for a banjo fitting).

yeah, i'm really digging that stipe on the tank - just need to figure out a way to do it.
i'll probably just paint it on after the initial clear powder coat.

cheers dagersh, that is indeed the Guzzi I was comparing it to.

update - March 13th

decided that i really don't like the looks of the Maier side cover... so i decided to go after the one that came one it.

from what i can tell it's been broken into several pieces and the previous owner decided to drill and 'stitch' it together?

looks like he took some time doing it as everyone of these stitches are twisted tight inside the cover.

doesn't matter though, a pair of dykes took care of these in a matter of seconds.
mixed up some general epoxy i had laying around and covered the cracks in the back

hey look! the original color!!

i'm letting it sit overnight to cure. Then i plan to attack it with some bondo to fill in the holes and paint it matte black with the same paint i used on my headlight bucket.
- in the world of paint, one brand's matte black can vary significantly from another, so i try to stay with one brand.

whilst 'fiddling' the other day, i accidently dropped a jumper pack right onto one of the turn signals i had taken off - shattered lens everywhere.
so i made a nifty shop light!

still trying to find that tube for my brakes - HEL suggested using any ol' tube that will fit (which is what i planned).
still can't decide on a seat. I like the one i posted earlier from AirTech, but i have a feeling it won't be easy to mount.
i can buy a 'direct bolt-on' CR750 replica seat from them, but it doesn't fit my bike - the hinge points are opposite. plus, i don't think i want a seat that is that wide.

Hell, I liked the stitching. The true frankenbike. Are there neck bolts up around the headstock too?

heheh, as cool as it was - it wasn't structurally sound.
and really didn't fit into my 'grand scheme'

Still toying with my veypor set-up, I have a different speedo pick up so working on a bracket for it. At this rate it will be another six months before it's on

MrFry · « **Reply #106 on:** March 14, 2007, 11:26:16 PM »

latest update...
my epoxy job didn't hold up to well when i started sanding the bondo - bummer.
so i did it again with reinforcements this time

i layed strips of the metal mesh across the longer cracks and then epoxied again.

while that cured (again) i decided to see how the Maier cover looked with a matte finish. Went after it with 180 grit, and sprayed away.
the result:

not to bad i'd say - i may end up using this seeing as my other cover isn't going to well. I just hate having to unscrew to get to the fuses.

next came the caliper - after seeing some ideas on here i decided to see if a banjo fitting woulf fit directly on the caliper
answer:

yes
quite well in fact. I am going to call my moto place tomorrow and let them know - then i have to figure out new line dimensions.
i think i'm going to go ahead and have 2 identical lines made up - that way i don't have to buy another brake switch/banjo bolt at the master when i go dual disk.

took the dremel out and made a slit in the head of the Broken bleeder screw - still not luck. That sucker is stuck!
and i can't use the kit from Napa - i don't think it will leave enough 'wall' for the base to screw into

as far as the magnet goes - i highly suggest drilling through the rotor - it's super easy!

i was going to make an aluminum bracket to come off one of the caliper mounts on the fork - but the dust sheild seems to work ok (granted i havn't ridden much with it).

UPDATE
today - i worked on the seat....
decided to see what it would look like if i used the stock pan
taking what was left of the cover and the foam off was easy enough - or at least it would have been if i could get the bolt out of the 'buckle' on the strap!!

i tried everything, and it's stuck in there good (hence why you see a strap in some of the pictures).

relocated the hinges and latch so it would snug-up against the older tank.

also removed the fender (finally)
doesn't look too good i think. the seat rises too much in the back and shows the brackets for the fender

so once again - i'm stuck on the seat. The stock pan is too wide and doesn't really fit well for what i want.
Airtech said they were 3-weeks out for their seats...
Benji's Cafe Racer makes some nice seats - but they are a bit pricey (i'm sure you get what you pay for). I have a hard time plopping as much as i paid for the bike on a seat.
Team Hansen Honda has a nice CR750 replica seat - but i think that will be too short for this project

any more seat manufacturers i'm missing?

Roach Carver · « **Reply #109 on:** March 16, 2007, 05:22:55 AM »

you could make your own using the front half of your seat pan and make th back half out of an old tank.

doug_id · « **Reply #110 on:** March 16, 2007, 06:19:43 AM »

You could take your bike and seat pan to a welding shop and see what they could do for you.....basically you don't like the gap between the pan and the frame right? I am sure with some creative grinding and welding that could be fixed. Probably not cost to much to have that done.

MrFry · « **Reply #111 on:** March 16, 2007, 10:10:48 AM »

after i posted last night, i ended up going back out to the garage and fiddling with the seat.
i tried bending the rear of it with my hands and i think it looks better - but it could just be my imagination

it's still a bit higher than i would like, but i think i could live with that.
the biggest problem i have with this seat is how wide it is though - and i don't really like that full-covered seats. I'd rather have one with at least a fiberglass bubble on the back (preferebly metal - so i can polish it).

sitting on the bike last night, i realized this tank could really use some knee indents - but i'm not about to start pounding on it.

MrFry · « **Reply #112 on:** March 16, 2007, 06:47:56 PM »

finally got my leads from TrailTech.
Temp lead was smashed cause they put it in a padded envelope and not a box - i was able to straighten it out enough to use though.

before:

after:

installed the new tach-lead with resistors with the + going to the blue coil input wire, and the negative going to chassis ground.
it still jumps a little bit, but it is 10x better than before. We will see how it does on the road (the bike is unrideable right now due to it's lack of brakes...).

while "testing the gauge" i discovered something really cool...
MY BIKE HAS AN AFTERBURNER!!!

^^sorry, it was taken with a cell-phone

about what tempuratures should the bike run at?
i installed it on the #1 cylinder cause i couldn't get the lead to fit in the #2.

MrFry · « **Reply #113 on:** March 18, 2007, 06:39:34 PM »

....scrapping the tank i have (if someone wants it - make an offer. Polished tank with cap, and Kreamed).

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&sspagename=ADME%3AB%3ABCA%3AUS%3A11&viewitem=&item=290093836528

i just got that instead. I think it will make for a better 'cafe'. The one i was using was too short, and just didn't look right.

plus, as far as i can tell - this tank doesn't have any dents.

ditto

anyone know what temps the 750 engine should run at/about?

kslrr · « **Reply #116 on:** March 18, 2007, 09:14:42 PM »

I would expect 180 to 190 deg. F., maybe 200 on a hot summer day. My 350F runs at 180 on a typical spring day here in SoCal, and not much hotter in the summer. Your 750 will run hotter, but I wouldn't think by much.

MrFry · « **Reply #117 on:** March 18, 2007, 09:35:24 PM »

hmm
ok, i'll set the warning lights to about 210 and see how it goes (unless someone can tell me different).

my Ducati Monster typically runs about 240F on a normal - hard riding day...

MrFry · « **Reply #118 on:** March 24, 2007, 03:12:43 PM »

...aaaaand were back

finally got my throttle cables and brake line today
now i just need to grind down a banjo bolt to fit the caliper

also installed the UNI filters. I am noticing some backfire through the carbs. I'm thinking this bike could use a valve adjustment, as there is a lot of clatter.

Sorry for the hijack but does anyone have more photos of this thing?

MrFry · « **Reply #120 on:** March 25, 2007, 10:55:32 AM »

^^sorry, can't help ya. I think i found that in the gallery, but i can't remember.

how do you adjust the tappets on these bikes!?
i can't get a feeler gauge in there to measure it. I even went out and got the 'bent' ones, and i still cant get them to work.

gerhed · « **Reply #121 on:** March 25, 2007, 12:11:15 PM »

A bent feeler gauge will go in there.
You've got to make sure they are open.
You can wiggle them with your fingers.
--won't budge if they're not open--also gauge won't go in there.

i should be checking these with the timing at the "T" mark yes?
i made this out of a feeler gauge, and i can only use it on the first and last cylinder. 2 & 3 are blocked by the frame.

MrFry · « **Reply #123 on:** March 25, 2007, 02:44:13 PM »

ok, so i think i did it right (had to bend my feeler gauge a bit more).
and i adjusted them to .020" for the intake and .030" for the exhaust. It seems to run a bit better, but there is quite a bit more noise in the top-end now.
sounds like a sewing machine.

i need to fined myself a grinder so i can make the banjo bolt fit into the caliper - then i can ride!!!
...without a seat!

jclark · « **Reply #124 on:** March 25, 2007, 05:50:23 PM »

I could be wrong but I think the intake and exhaust tappets are supposed to be adjusted to .002" and .003". You may want to double check. That's what it says in the specifications section of this site.
