Daytona Special Barn Find

[DaytonaBarnFind]

That crossover intake setup is USA '79 OEM.

Very cool, its too bad it's cracked. Should I run a crossover intake like an RZ?

The carb joints for the RZ are a little different than the Daytona but you may be able to make them work. The RZ uses a larger female nipple on the manifold while the Daytona uses a smaller diameter male brass fitting for the hose to slip over. I doubt you'll be able to find any NOS Daytona 2V0-13565-00-00 manifolds. In any case, I would restore as-is to retain the functioning exhaust valve.

As Ed pointed out above it looks like you have all the exhaust valve components. Those are pretty rare since most owners took them off and tossed them back in the day. You also have an uncut rear fender which was another common mod that resulted in that part being rare as well.

Because it's so complete I would keep everything intact and restore it as original. There are tons of modified Daytonas running around but very few stock ones. It's worth more if it's original too.

The 2V0 model did not get the CDI that the 3J7 came with for Canada in 1979. Unfortunately we got stuck with points

I attached a few parts images for you for reference. You can find the complete Daytona parts book in the Tech Library

Those intakes look similar to the ones Economy sells with the rubber crossover. Brass nipple diameter may be a bit bigger though.

Finally found some time to disassemble the barn find RD. The insides all look really clean, especially the stator assembly. Next up is to clean the engine up before splitting the case to replace all seals. Bike has 3100 on it and compression was 155 in both cold.  Will rebuild the oil pump and carbs, and probably paint and polish the cylinders/heads, but this is very original bike so the plan to keep it that way.  Front caliper is seized so it soaking, and will rebuild all calipers and masters, yuk.  I want to touch up exposed areas on the frame, what the go to paint for this?  I would guess it should be brushed on not sprayed?
Constructive thoughts and ideas are welcomed.

Merry Christmas,

Rob

Looking good!

My 4U0 was in similar OG complete condition when I got it

I initially intended to do a faithful all original resto as well

The brake calipers were the turning point. The original JDM specific calipers are crap, and had not fared well from decades of neglect. The JDM specific front master cylinder was even worse

I've kept the chassis as original as financially possible, but gone full race on the engine.

Best of luck with your project 😎

Any head polishing experts? What's the best approach to restore this head to look like new?

Vapor blast, run thru the wet sand grits from 400 to 2000, then hit the buffing wheel with rouge.

Jim's got good advice.  I am no expert, but have spent many many hours at the wheel.

I started by bead blasting, then did everything at a wheel with various grades of polish.  I think the 400 up to 2000 grit would have been a better route, but the 'wheel only' worked for me...

Here's my very basic setup and some outcomes.  Best advice is wear gloves, a respirator and goggles, the flying compound is nasty...

Sounds like a plan.  Thanks for the info.  I'm not looking for it to be too shinny, just back to the "factory" look.  Still the same process, but just less of it?  I'm in NJ as well, just west of Newark off 78.  Thx Rob

Nice score on that bike with factory pipes, very hard to find.  I posted yesterday in General Chatter section looking for information on the ID sticker on the steering head. Maybe you can help me fill in the missing information.  I have one that I am restoring with stock pipes as well, but not nearly as nice as this one.

While the motor is apart this would be a good time to get the combustion chambers reshaped for modern fuel. Maybe even cut the head in half for easier assembly/future service.

[DaytonaBarnFind]

Does this help?

Another angle

Case came apart easily. Crank bearings look dirty but are very smooth.  Whats the best way to clean up crank safely?
