GL1100 PVC Manifold and 34-3 outta box Carb

[dkl]

I said before, I worry about the How not the Why.....but u asked, so here is my thinking on the single runner manifold and the rules of carburetion.
The GL1100 has a 1085 cc engine, I was taught it needs about 1/3 of the cc engine size for Plenum,,my math show it needs 342 cc of plenum volume, but that is if all cylinders pulled at the same time---since only two pull at the same time it needs 170cc volume.

The runner itself serves as the Plenum, the single runner is 1" diameter and 11" long, the volume of the runner is 140 cc, and that does not factor in the tees and fittings going into the rubber boots,,,,,My math and reasoning are probably wrong......but that is why I think it works...

As long as you make the math suite your results :smilie_happy:
Great work on your manifolds, this one even looks pretty :good:

 

[dkl]

That's why I use D Common Core Math.....u can get an answer that makes u feel good about urself.....you know there is no right or wrong nowdays.

And since one on right and one on left are pulling in, volume wise it's enough.
Might fall short on sustained top end under a load.

id say for one barrel carb..id say it matches up well

Got finished modifying my trailer, we took the bikes on a 60 mile trip to the lake to try out the new manifolds, and how they handled a 400 lb trailer. Cruised in 4th gear 55 to 60 easy, and 5th went to 80 up hills no problem. It suits us to a TEE. Gas mileage pullin trailer---no comment.

Yep, it takes some mpg off. But, for the curious, what kind of mpg are you getting on the highway?

 

[dan filipi]

I am curious also.

I have been getting ready for our July 1st Texas-Oklahoma-Arkansas departure, jumping on bike test pulling trailer, unhooking trailer, running to the auto-parts, so mileage on new set-up I have no definite answer yet. I will know after trip and will post mileage and how they ran,,,,,or how well the tow truck hauled our bikes,,,,,,

Wife has a new toy...she is making decals, Decals going on my Trailer and the Bikes,,,,will post pictures later.​

Is she taking orders for decals?

 

[dkl]

We have been in retail for 40 years, and that is e'nuff. She is not ready to start a new Business Venture, as of yet.....we r just having fun.

 

[dkl]

Bikes r ready, Trailer is packed, Pull'n out July 1st....... It is worse than being 6 years old on Christmas Eve.

 

[slabghost]

Enjoy the trip! Got a link to the decal maker?
