Anyone else experience this? I seem to recall someone posting about this, but no matter how I search I can't find info. This is the most perplexing thing I've experienced with the 630- which says a lot given the quirks this bike throws out. I re-installed my airbox (it's in right- the mounting holes lines up right and box is flat against mounting surfaces, boot mates right to TB) and the hose/pipe along the top- that connects up to the big nipple on the valve cover- doesn't even reach the nipple. it's about 3mm short of touching it, and a good 1/2 to 3/4 inches from where it'll seat over the nipple in the proper position to tighten the clamp. Weird/crazy. There's only one correct routing of it- it goes behind the top edge of the box and around the backside of the clip/nut that the top airbox mounting bolt is received in. You can route it over the top edge of the box, but that doesn't change the pickle. Since there's only one correct way to route it properly it seems the only solution is to get another hose and cut it to the right length, so that's what I'll do. The only explanation is that the pipe shrunk, but that's just not possible....which is why I say this is very weird and perplexing...a weird thing to have brought today's work to a halt. Thanks- Eric
I can buy that it would shrink more once tension is removed, they tighten up to the point of popping out of the airbox sometimes and you know they weren't that tight when assembled. Longer hose or cut and put in a coupler should be the answer. .
Huh...maybe so then- thanks. Just seems as though that kind of shrinkage of that type of material couldn't go that far. I'll stop by an auto parts store w/in the next few days to see what they have.
I got shrinkage too (hey, it was cold!) I noticed it had popped off of the airbox when changing the battery. I just went to the auto part store with the old hose, and got a crankcase vent tube about the same diameter. Reused the 2 end connector, and good to go.
Bring it inside the house and let it warm up some. Then re-install and clamp on valve cover nipple leaving the other end floating. Then pull/stretch hose into airbox and secure with a zip tie so it can't pop out. Or just unbolt your airbox and attach the hose at both ends, then reposition your airbox and bolt it back down. The later method is how I did it but I was replacing my airbox anyway so it was already off. _
