You're right; the steel build (on that other thread) might be the way to go. Way cheaper because lots of guys can weld or braze steel but not AL. And steel pipe and channel is cheap and available. I will be following that one with interest.[url=https://www.classicgoldwings.com/forum/viewtopic.php?p=109314#p109314:1wvuj1vs said:
Well I'm committed to this and I think I've spent all the big bucks now. :heat:

Yours will be better in that it's aluminum and should transfer best better, unless the additional thickness comes into play.

OK so I got it all back together and had it running in the driveway. I am happy to report that there are not coolant leaks. Here is what I did:
Because the connection at the back of the centre coolant collector and the plenum chamber are so close, I decided to use 3/8" ID hose instead of 1/2" because it has to make a fairly tight loop.
At the front of the heating chamber I had to use a 90 degree fitting because a straight one comes too close to the fan motor. The coolant return line is 1/2" ID.
The spacer plate down at the pump suction worked out really good. The rad hose still fits nice and the coolant fitting lines up pretty good with the gap between the timing covers and the radiator.
When I got the plenum back from the welder I realized the I had forgotten the burp valve to release any air that is trapped in the plenum chamber because it is the high point of the engine cooling system. So I had to drill and tap a 1/8" NPT hole and put a 1 1/2" nipple and valve.

So how did it work. Remember the temperature sensor I bought in Post #80; I stuck the sensor end to the bottom of the plenum heating chamber with aluminum tape and set the digital readout thing where I could see it.
With bike idling I saw the temperature go up and up until it reached about 70C (158F) at which point the OEM temperature gauge had risen to the end of the narrow line. That is when the T-stat opened and the plenum temp. dropped back to about 55C. I guess because now there is a bunch of cold coolant added to the mix. I was getting cold and I could see that it was working so I shut it down and went in for supper.
I figure it worked pretty good because max coolant temp at full warm up is probably about 100C and the bike was not at max temp when I measure 70C at the plenum so I am thinking that at full warm up it might get to 80+C which is pretty hot.
So next time I will keep it running until it warms up enough for the fan to come on and see how warm the plenum gets. Also, remember I swapped the primary and secondary low speed jets so now I have a 60 in primary and 50 in secondary. I will swap them back to their original position and see if the stumble disappears.
Of course this is all well and good with the bike idling in the driveway but it will be interesting to see if my plenum heater can keep up when the bike is rolling down the road and way more gas is flowing through the plenum. I will have the temp gauge there to monitor it.

Good progress Brian.
If I remember correctly you had a bad bog on acceleration, is that right?
Sorry, its been awhile so I'm not sure how your gauging effectiveness of the heat.

Yes Dan, I had a big time bog with an unheated plenum. In post #92, page 7, I swapped the primary and secondary low speed jets. I did some launches in the driveway as a test and the bog went away.
So now I want to see if the original jetting will be bog-free with a heating plenum.
Also Calgary is about 3000' above sea level and other vehicles I have played with ran better with leaner jetting. So eventually I think it will run best even leaner. But rather than putting in small fuel jets I might try what you and Joe did and put in larger air jets. I remember you saying that it helped to atomize the fuel with more air.
It is very cold here now and lots of ice and snow on roads so road test is out of the question. But I can do launches in the driveway as a test.

Yes. The bigger primary air bleed will also lean the primary jet by allowing more air to be drawn in and mixed with the gas before it goes through the primary jet.[url=https://www.classicgoldwings.com/forum/viewtopic.php?p=109427#p109427:d4z41u8s said:
well im applaud brian ... I cant seem to muscle up any work in this weather ...well brian your test mule sure the beats the cali one of dans for the heat issue ....if we can get this bike running well at brains house and defeat the icing issue we have defeated it ... this is a great thread going on ...and perfect timing too ....I say the one bent hose needs to be refined to a solid horse shoe of some kind I don't think that's good enough for reliability on the hose just to much to bend ... with strait hose as couplers ...
it will be interesting to see how jetting is effected and how much ... this build has no transition piece either ... so that some thing too that interesting in results of outcome ... great work brian

Thanks Joe. The proof of this setup will be when I road test it but I am optimistic now. Was pretty happy with how hot it got. Should be able to improve by insulating the plenum.[url=https://www.classicgoldwings.com/forum/viewtopic.php?p=109475#p109475:zkjdb07h said:
You are right about that hose that makes a U turn. I see, now that it has been warned, it is kinked so will have improve. That is some el-cheapo hose I had laying around. I know there are better grade hoses that have wire reinforcement so won't kink so will investigate.
Right now I am working on the air cleaner mount. Might be good to have it on for tuning.
I read on the other thread about you putting a turbo on Hooch...holy crap. I want to see that.
Brian
well turbos in my experience with farming is great set up to get the most efficient running ... I don't have a super lot of experience with turbos on gas motors but that never bother me before on not doing something ... it seems rather obvious ... single carb lends itself to this nicely ... and hasn't really been done well yet ... mostly turbos to big and not set up right ...I don't have one yet but they are priced right

Might be tough to balance that bugger on two wheels.
if thing ever comes up to speed it will do just about anything except just fall over ...

OK so I got the air clear mounted and the breather hose hooked up and had the bike running again in the driveway. I swapped the primary and secondary low speed jets back to their original position (see post #92).
It is still cold here (-15C) but a nice bright sunny day so I let it run until the fan came on. The max temperature I got on the plenum is 85C just before the fan comes on. When the fan comes on it drops back to about 75C.
I tried some launches in the driveway and feel no stumble or hesitation at all. Can snap the throttle open as fast as I can and no hesitation.
When I said before that there was now leaks, I lied, I discovered a small leak from the lower Rad hose. I have all the OEM hose clamps still on there (those wire type with a bolt) and replaced the lower one with a regular worm-gear type and the leak stopped. I will replace all of them.
The only other thing is to insulate the plenum. I think that will be important to keep the plenum heat in when the bike is moving down the road and wind is taking the heat away.
Other than that there is not much more I can do until I can take some good long test rides and check the plugs etc. Maybe play a bit with the jetting.
Just have to wait for spring now.

great brian we are in territory where heat jetting have to come together to make both right id say ... good work
