JMaN05 Posted December 2, 2015 Report Share Posted December 2, 2015 Hey guys. Just about finished with my yfshee. I will post all the pics soon as i finish her up. Another week or so. But my last problem i encountered i need help/advice with from the banshee veterans. As you all kno. The banshee rad has two nipples on top. One for the overflow tank and the one that connects to the nipple on the head between the cylinders. I used an oversized yfz rad for my build. They do not have the two nipples. So my question is, aside from the obvious having the second nipple welded on, are there any solutions for this? Suggestions of the board highly appreciated. Could i tee it to the overflow hose? Cap it off? Use a vent such as gas cap one? Please advise Quote Link to comment Share on other sites More sharing options...
Guest XDOVAYA Posted December 2, 2015 Report Share Posted December 2, 2015 I'm in a similar situation my overflow bottle hose fell off the connection to the radiator last time out riding trying to figure out where it connects back up to maybe it goes to 1 of the nipples you mentioned?

JMaN05 Posted December 3, 2015 Author Report Share Posted December 3, 2015 The hose from overflow tank goes to the nipple by rad cap. The other nipple is on opposite side of top of rad. That connects to the top of head between the cylinders. The nipple opposite of rad cap does not exist on yfz rad. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted December 3, 2015 Report Share Posted December 3, 2015 Cap it. It's a air bleed. That's the highest point. So it will push air out as you fill it. I'm sure if you run the bike as your filing it you should get the air pocket out. Or just keep the cap off and put it on when coon stays to flow out 1 Quote Link to comment Share on other sites More sharing options...
JMaN05 Posted December 3, 2015 Author Report Share Posted December 3, 2015 Just cap? And would you cap it then just let the rad cap loose while running to bleed the system? That would be my bet. Or are you think leave rad cap tight. And let idle and gargle out of that spot then cap once air is hopefully out? Quote Link to comment Share on other sites More sharing options...

JMaN05 Posted December 4, 2015 Author Report Share Posted December 4, 2015 Hoping for some more certain answer haha. But you believe capping it would be better than a "t" to the overflow line? Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted December 4, 2015 Report Share Posted December 4, 2015 Hoping for some more certain answer haha. But you believe capping it would be better than a "t" to the overflow line? Yes, as it will be pressurized. Quote Link to comment Share on other sites More sharing options...

I say it like that because you're honestly over thinking it. Just follow the lines and you'll see how/what/why. Once you put a little thought into it you'll understand.

JMaN05 Posted December 4, 2015 Author Report Share Posted December 4, 2015 (edited) I have put plenty of thought into this and im not overthinking anything. but thanks for That. Considering I just spend thousands building this bike, i would say having the cooling system operate properly is pretty damn important.

JMaN05 Posted December 4, 2015 Author Report Share Posted December 4, 2015 Yes, as it will be pressurized. But from where this connects to the rad, wouldnt that make the overflow bottle pressurized as well. Considering they both go to essentially the same spot. Just opposite sides of the rad. Again. I only ask so in depth cause we are talking alot of money invested here. Logically i would assume connecting to the overflow would act very similar. An air bubble on the system would then come out in the tank? Quote Link to comment Share on other sites More sharing options...

Fill the system and it'll piss out of it. The over flow is blocked by the cap. Cap opens and you get over flow. That line plugs direct into the system via the opposite inlet that you don't have. So it needs to be blocked. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted December 4, 2015 Report Share Posted December 4, 2015 Cap it off! Don't run that anywhere. I ran the motor in my Hybrid chassis that way. Quote Link to comment Share on other sites More sharing options...
JMaN05 Posted December 4, 2015 Author Report Share Posted December 4, 2015 Thanks guys. Much appreciated Okay, might as well ask one more question while i have some attention of the board. Question, relating to The little breather hose that comes out of th back of the motor by the rear engine mount. Also the breather that comes out by the water pump impeller. I kno the two are connected by t. But in the clymer it looks like the other end of the "t" isnt just hangin. Looks like it is plugged in somewhwere... Any ideas?? Thanks again. That should be the last question. I am fabbing up some head pipes tonight. Well at least one. I can smell the end!! So exciting!! :] Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted December 4, 2015 Report Share Posted December 4, 2015 The front can be blocked. There's actually a billet block off you can buy. The rear I have just running down Quote Link to comment Share on other sites More sharing options...
