Modest beginnings of my M750 project

[memper]

Whats that rod sticking out the side airscrew adjustment?

Oh and if your running velocity stacks are you just using a small filter on the crank case breather?

Im glad your sharing all this because I have to do most of the same stuff on my 750 later this summer.

The rod is actually a cable for adjusting idle speed. The overall access on these carbs is a dream. Yes I have a small filter on the crank case. Btw, anyone know if its illegal to use said crank breather on the track? Or do I need to put a hose before the breather and affix it to a catch bottle?

Depends on the track day provider.

Race organizations generally require a catch tank.

That would be my guess. Too bad I tossed the lot when I ditched all that stuff. Guess I'll have to fab up something. I will be trying the new track in Davenport, NY come August.

 A PBR pounder can will do the job.

not much of a drinker...probably use an aluminum drink bottle for hiking. The catch bottle needs only one hole for the crank hose or does it need another with a one way valve on it or something like that?

Regulator/Rectifier:

I am wanting to hide it. I am considering making a bracket and mounting it to the back of the battery box, opposite of the carbs. Is this a bad idea? I might be concerned with overheating it but I have seen some folks straight up cover the damn thing under their seats with zero air flow with no problems. The plan is to make the bracket and mounting plate from aluminum to perhaps act as a heat sync.

My point exactly. I wonder if I put the rr on the battery box, I could make a sort of ram air vent that pushes air onto the rr. Basically just a big rubber or silicone tube (1" maybe) that runs from the front of the bike to the rr.
Would it work?

except standing still.

That idea has been scrapped. New idea in the works.
Gonna try to mount it vertically off the tabs where the old external fuel pump was. At a glance it looks like the holes will line up.

My super hawk had the retifier behind some plastic bodywork on the tail. It burned up. Not sure if it was heat or just faulty. The replacement had been superceded with a new part number and was not identical in apperance. That sums up my experience with bad rectifiers it would be prudent to let it cool someplace.

First round of mods and adjustments completed:
Valves set
New rear tire
Braking (Denmark) pads
LED headlight
Shaved seat
SS tank
FCR carbs
Relocated R/R (under bottom tree)
Relocated ignition (right side front)

Next level in a couple weeks:
Bultaco quarter fairing

White header wrap
Fiberglass cafe seat pan

Black mini speedometer (mechanical)

Here's a couple pics from my first ride of the season. FCRs are no joke. Low end jerkiness (inner city riding) is gone. Throttle response is so smooth and responsive it almost feels FI. The clacking at idle is awesome and with straight velocity stacks she really cooks. Still gotta fine tune the screws underneath though (yes I know they are each for different functions). Don't know if I have more HP between the FCRs, gp Dan Motos, and V stacks...but it sure as hell feels like it.

[SpikeC]

 I love what you're doing with this bike!

[MendoDave]

Me too. Im glad those FCR's are working good. Ive never heard anyone say they sucked.
Cant wait to start putting them on mine.

Thanks spike and dave!
