Same passage IIRC.

The valve cover is not under pressure, and therefore does not need anything more than the rubber gasket that is stock.

The oil pathway runs up the head bolts to the rocker arm assembly. That is why you have dowels to keep it positioned properly.

The issue is the oil pathway. It runs up the head bolts to the rocker arm assembly. If the gasket material spread over this pathway, that will stop the flow.

A lot of people disregard manufacturer warning and instructions.... For example: Scoots call for 91 or higher Octane, but yet you will always find Joe Blow saying the manufacturer don't know what they're talking and 87 grade is just fine "because they do it all the time".... If a scoot manufacturer calls for 10w40, again, you will find Joe Blow telling people Oil weight don't matter and you could run chain saw bar oil if ya wanted... I've seen people actually recommend fish tank hose as a substitute for fuel lines... They said "It would be cool, it's clear"....  It's these kind of trivial things that people make complicated... My approach is this.... If the manufacturer calls for X, operate the device per X's instructions. The manufacturer is the one who actually makes the stuff and might just happen to be "experts" in the area... So why people disregard a manufacturers intended purposes or disregard warnings is a mystery to me.... But hey, to each their own and for all I know, all these alternative may actually be right... I just prefer listening to the manufacturer. I'm sorry, but I have one problem with this: these are the same manufacturers who put out scooters with parts we All say to change during PDI. We don't trust their hoses, wiring, connections, or even their ability to tighten nuts and bolts, instead we recommend that all these parts are changed, tightened, or otherwise modified. With that said, why should we consider the manufacturers to be the experts on tires, fuel, or oil if we don't trust the basic construction? Especially manufacturers from a different region with different tire, fuel, and oil standards, and extreme difficulties translating the most basic instructions, much less industry standards? |

You have to realize, water vapor causes rust faster than actual water. It would be an interesting experiment, but be prepared for rust in the most unexpected places.

Had a full day of serious riding yesterday. Got a call waking me at 6:35 from my nephew. His Roketa busted a belt on the way to work on the other side of the valley and he needed a ride.
Took the freeway, strong winds pushing me across the lane from time to time, kept up with traffic fine. Got him to work, then took the beltway around the valley back home, spotty areas of rain, nice stable ride on the wet roads, but into the wind uphill had trouble staying above 60mph (very strong gusts head-on during that part of the ride).
Gathered tools needed to repair my nephew's scooter, then took surface roads to Scrappy's to buy the new belt. From there I took the interstate along the strip then up to the speedway, wind to my back, no problem keeping up with traffic till I hit the short stretch just before the speedway with a 75mph speed limit, so traffic was doing 80+. Fixed my nephew's scooter, then back on the beltway home, no rain this time, but still strong winds.
Took the freeway back to pick up my nephew after work, his scooter is a BBKed 50cc, so I had to follow him for a while to make sure the repair was ok, then took the freeway back home.
All told I rode close to 200 miles, about 140 of them at highway speeds. I have never felt more satisfied with this scooter, best money I've spent in years!

Check the inner diameter of your performance exhaust at the header. If it isn't bigger than stock, you'll want to open it up, perhaps even fab a new header pipe. Often the performance exhausts are choked by a small I.D. header.
Get the strongest valve springs you can find. If you want to red line, you will suffer valve float without the strongest springs.
Are you going to stroke it as well, or just do the BBK and flow mods?

I'm no expert on this, the best advice I can give is to take them to a machine shop that can fix them with the proper equipment.

FYI- even though there is only one combustion event every 2 revolutions, the plug does fire every revolution on a 4 stroke.

A dab of lock-tight should do the trick. Don't use the strongest type, you want to be able to remove it.

I think if I was in your shoes, I would pull them and use a dremel to fix them. The best methodology is to take it slow, shaving a bit, assembling and testing, then disassembling and grinding a bit more, reassemble and retest. You can't replace what you remove, so slow and painstakingly is the way to go.

Nice looking ride! I went to high school in Waynesville when my dad was stationed at Ft Leonard Wood, about 30 miles south of Rolla. I miss St Patrick's Day in Rolla, what a blast! That's some fun areas to ride in, and this time of year I bet it's just beautiful! I hope you and your wife enjoy miles of smiles riding together!
