Well, the engine on the ruckus is a stressed member of the suspension so is subjected to a lot of loads, that means any drilling has to be reamed and deburred to prevented stress raisers on it, that can lead to cracking

Ahead of the engine pivot should be much less stressed, drilling in an area like the timing chain case should be much less of a gamble if a gamble at all.

DD, you're only suggesting to do this if you have an '05 or earlier, right? Yeah, this mod is essentially replicating the ventilation improvements Honda made for 2006.

Ahead of the engine pivot should be much less stressed, drilling in an area like the timing chain case should be much less of a gamble if a gamble at all. I'm not sure if it matters, but locating this new hole ahead of the pivot would place it fairly close to the existing hole in the valve cover. This may mean that you get good ventilation at the front of the engine but the air in the lower case doesn't really cycle. Perhaps you could create a hole on the side cover of the engine that is behind the flywheel/alternator. That way you aren't modifying the main case. It would be tough to route a hose back there though. It may also be possible to modify the existing cam chain tensioner. Lastly, maybe you could drill a hole in one of the cam chain tensioner bolts so it's hollow and then somehow fit a hose over the bolt head. I dunno how you'd keep the hose on there though and you might end up destroying the bolt when you torque it in place now that it's weakened. Here's an idea, drill a hole near the top of the side cover (behind the flywheel) but then also drill a hole in the main case (above the flywheel) so you can route the hose up through this hole, rather than having to route the hose all the way out past the rad. This part of the main case is just a fin, so it shouldn't be subject to any loads. Plus you can take the side cover off relatively easy so you can remove it, drill a proper hole and then put it back on without worry of getting metal shavings in your engine. I guess if you're rebuilding the engine anyways this doesn't matter but it would be easier for regular owners who simply want to retrofit the improved ventilation system. Someone should really sell a kit for 2003-2005 owners. I can't think of many aftermarket Ruckus parts more important that one that saves your engine.

Hmmmm, I think you've just sparked something...
I was looking at the pics I took when I changed the oil pump-side crank seal on the sister's bike... I dont think there's enough clearance between the cover and flywheel to acomodate mounting a solid fitting, but while I was staring at the pictures, I saw something...
THE OIL FILLER !!
It'd be fairly easy to drill through the dipstick's handle and stick a plastic nipple on it with some epoxy, then just connect a hose to it going to a breather behind the frame. Then just use a small hose clamp that can be released with one's fingers to easely disconnect it for oil checking or changing purposes.

Clever stuff....drilling a hole through the dipstick does seem like a good option. Once you drill the main hole, you could enlarge the first part of the hole and then epoxy a tube into the dipstick which would be your nipple. As long as you were careful, this should work good. If you did this and bought that one way reed valve from the Elite 80 that I posted ($8) then you could solve this ventilation problem for super cheap.

Cheaper would be junkyard diving for an inline checkvalve from a car's brake booster.

I dunno how you'd keep the hose on there though and you might end up destroying the bolt when you torque it in place now that it's weakened. Maybe banjo bolt and hose fitting for hydraulic brakes. I doubt that it would have a lot of flow, but you're not looking for 650cfm.

Chanito --- I am gonna have JC do the Big Bore build for me because I don't trust the local shops to do it right or be familiar with the engine and I want to use the thinner gasket, hence having someone like JC do it. However, he says he just sold his last Big Bore kit and needs more so I'm wondering if you have any left to send him?

Yeah it's bummer to have to take it apart again. It will go a lot faster/smoother the second time though. For both of you guys, when you do the BB, I would order the revised cam chain tensioner from Honda (part #1 below). You need this so you can connect a second ventilation hose to your crankcase. $65 is a lot but it's way better than spending $150 plus a lot of your time to rebuild the engine in another 2 years. Once you have that, you still need to connect a hose to this, add a one way valve in the hose and lastly, get a filter on the end. You can buy the one way reed valve from Honda but it's expensive. You need parts #3,4,5 and 7 for a total cost around $75. You can probably find something cheaper elsewhere if you're willing to do the research. Lastly, you need to connect this hose to a filtered air source. You could connect it to the airbox somehow or just buy a small K&N filter and toss it on the end of the hose. if you connect the hose to the air box, then is the one way valve not needed also would a car pcv valve work too, as it only works in one direction im sure those are cheaper which way does the air flow, out?
