Kliff has an excellent point. When the tensioner went bad, plastic pieces went into the oil and through the system, possibility is that they can do a lot of damage to any bearing surface.

That's along the lines I'm thinking... I hope, though, that that will be slow enough to allow me to wait for an entire replacement this winter...

well then at least drain the oil and see if it has plastic pieces floating in it, but they can be pulverized into almost nothing

I have replaced the oil twice since then, still no particles found... Waiting on a new gasket set from PFS, then I'll get another oil change in... Seems to be running well at this point I think my valves are too loose though, I'm gonna check that again tomorrow. It might just be that I'm used to the .05mm sound instead of a .004" sound.... It almost has that choppy sound like when you blow through a fan the opposite of flow... I almost forgot, I have a high-pitched tone that changes with throttle... Is that an air / pressure leak somewhere? Is it probably a gasket? Also, on the metal head gasket, what's a good sealant to use?

Cool, I'll pick some of that permatex up. But, I have a new development :/
My exhaust pipe popped today, pulling away from a stoplight, it just went POP, broke off right below the flange weld bead all the way around, and right before the muffler weld bead it cracked about halfway around.
It's starting to look like I need to save up for a whole performance kit that comes with an engine and exhaust faster than I thought I would, so I'm wondering if I can have this repaired with more welding? Would that be bad? I think I'd end up with 1/2" - 3/4" wide bead :/ It's already 1/4" - 1/2" when I got it!!

Picked up a SS exhaust system from PFS.com today, they let me walk in and pay cash I got a 7 jet set, and a uni filter, too, to try to eliminate my overheating problem and balance the SS performance exhaust... Is anyone familiar with this kit? Does the included pipe just slide into the muffler, or am I supposed to weld them?? www.partsforscooters.com/190-36__GY6__Scooter__Performance__PipeDrained my oil today, and had about 1/2 of it left in there after one 20 mile ride in one day, pretty black for one day riding, too... I got another gasket set this week, and will set to work on reassembling my engine again tomorrow. Disassembled it tonight to clean everything up, and I saw that my piston head / face is completely black, it was a nice silver color when I put it in last weekend - everything behind the rings is still that nice color. I haven't been having smoke from the exhaust, but I did notice a smoke coming out of the shroud on Thursday, and I had leaks at the gaskets, so trying to get everything cleaned up good for new gaskets tomorrow. I'm planning on just installing the exhaust and air filter first, and seeing where that puts me on the rich/lean scale... I cannot be sure if the head turned black before or after I moved the jet needle, but I am pretty sure the spark plug got redder afterwards, and I know the exhaust popped afterwards... May all be due to a gasket leak?? Is that right thinking? Is there a semi-quick way to tell where I am on rich / lean, other than riding it a couple miles and seeing what the plug looks like? GES did offer to replace the muffler, but I don't want to deal with this again very soon, so I changed my mind about pursuing the warranty. Although, naybe I should've gotten the warranty muffler and made sure everything works right before I put the performance one on... Always talk too soon and think too late :/

nice looking muffler, I do not think it is designed so the user has to have it welded, does it come with an exhaust pipe clamp?

No, I found a couple of people who have this muffler, and it's just a slip-on, but you HAVE to use both straps on the muffler to keep it from slipping off as easy at it slips on... I ended up bolting the mounting bar to my shock mount, and it seems to be working GREAT. I had a 103 main jet original, tried a 108, but it was still WAY hot after just 2 minute ride, so I shot up to a 115, which has eliminated all of the backfiring, and made idle much quieter than the 108 was... The muffler has a nice voice, not too loud, but when you hit the gas it announces your presence I got rid of a flat non-acceleration spot that I had from the beginning between 25-35 or so... The flat spot might've moved up to around 45-50ish, but I can't tell exactly, my speedo gear is still broken, and I honed and put the other cylinder in today while I was installing all the gaskets, so I didn't try pushing anything too hard today, just wanted to run it around the block and see if there were any problems. After the 115, I don't think I do, but I'll know for sure when I get a new plug, AZ didn't have one :/

you need to mount the muffler to something that does not move, shocks move up and down, it will cause something to break the pipe might break loose with the movement. Do a plug read and see if you might still need to go to a bigger jet too.

Hmmm.... The bottom shock mount is the only hole anywhere near this muffler... It's located on the triangle bracket that attaches to my back wheel, midframe and mudflap. That bracket is what my stock muffler attached to, although it did not use the shock hole, the whole bracket moves same as the shock hole...... I /thought/ it would be safe there, but I guess I might have to fab something if it's not. I'll post some pics tonight.
You might be right, I still might need a little bigger jet. I get a single backfire / pop every once in a while, but not regularly... I just finished a 20 mile ride, and it backfired maybe 3 times.... It seems to happen when I let off from over 3/4 throttle, whether a little drop or a lot. The old plug hasn't changed color, and I still haven't found a store with the right plug, so I can't really read it right yet, but it's on top of my list. I do think I might still be running a little hot. How can I tell when I get too rich? Also, do you think I should look at adjusting my idle jet too? The idle screw doesn't seem to affect anything until I'm over 3-1/2 turns out, and I'm afraid it might rattle out that far out... How many turns does it take to make the spring pop out? I haven't wanted to try, lol.
About as often as the backfire (not at the same time, tho), I hit a hiccup during acceleration. It kinda bogs for 1/4 second then jumps forward. Hopefully, I have a 120 in my jet set, I'll try that when everything cools down a little. Thanks for your help Rebel!!
I think I'm still losing oil. I checked when I got back from 20 mile, and it looked like 1/2 stick, but I was trying to hold the bike level on an incline with a hot engine, so I'll check again in a bit.

Yeah, I'm pretty sure I need a bigger main jet... I just rode less than 1/4 mile around the block and the header already was blazin hot. A lot more backfiring at low throttle (1/4 and under)... I didn't get past that on this go around, was testing the new Gates belt...
The 115 was the biggest jet in my set, I'm gonna try to see if PFS will let me exchange the rest of these jets for a couple bigger mains and a couple of pilots... I have to say, wow, I didn't really expect such a noticable difference in power when I put in the Gates... I even managed to put it on without taking the pulley off.. Wow, I need an impact wrench!!

Well, I just put the stock filter back on until I can get some bigger jets... I'm glad I'm running!!

running a little rich is better than running a little lean in my opinion. gives you a little more more power and runs a little cooler.

My top end seems to be peaking out at a lower rpm, and i think speed, with the air box on... Not bad, but noticeable... I sealed the PAIR ports today, but it didn't fix the oil leak like I was hoping... I guess this weekend I'm tearing it down AGAIN to redo my gaskets.. I think I'll try a silicone tube valve cover gasket tomorrow, tho, do you have any recommendations for something that'll take the heat?
