I'm out of town right now, but over the weekend, I went to split the cases of the Sprint's motor to see what's ratting in there (current theory: cush drive springs).

Aaaand....the SIP Performace/VAPE flywheel is stuck on. Destroyed not one, but two flywheel pullers trying to get it off. next up is grinding down a three-armed gear pulled to fit under the central section of the flywheel and trying that. If that doesn't work, it'll be time to get destructive.

On the bright side, I replaced the shift cables in the Sprint and it made a huge difference in how shifting feels. Lastly, realized that the irritating rattle I was hearing is the front fender crest. Currently, the repair is a bodge of sticking tape under the ends of the crest, because I can't seem to get the pinch-locks to tighten up. Anyone got any advice on that? Would pulling it off and threading the posts so I could lock-nut it on be too extreme?

Overall, though, the bike is really, really fun to ride these days
To extreme? I donít think so...

Pull the fan cover and itíll measure 360*.

The official buzzwangle came with a machined threaded base for the inclinometer. Cost 100£ but it paid for itself in beer at the last rally I went to. Everyone wanted to try it for the taste of a frosty beverage.

Yeah I know the official buzzwangle can, I was asking about Ginchís buzzknockoffwangle. Some only do 90į x 4.

once you have located and marked TDC how much more degree of turn does one need?

I bought an inclinometer a while back, but never really sorted out a good way to mount it.

What's your mount?

Original one has different threads for M26,27,28 and something else. Iíve just used the M28x1 one. The threaded piece with the picture is a piston stop.

If you have a flywheel extracting tool and have a welder, you could weld a flat piece to the tool for the inclinometer to sit on.

I tried that. The flywheel extractor won't fit over the flywheel nut

Leave the woodruff key in and be gentle with the flywheel. It wonít wobble too much.

We need to think of some way to make it work with a points flywheel

I was just testing it out for a way to hold it on the flywheel without using an extractor. So it's stuck there with magnets and some lightweight angle. Seems solid enough.

Mike, yes. The degrees go down again once it gets to 90... hadn't considered that. I wonder how they make it do more than that?

Unfortunately it does not make the noise...

Finally got the smallieís jetting dialed in ... took it for a good long romp, wound it out, temps stayed down. Hadnít ridden it for a while, forgot how much fun the little bikes are!

Gads, that's a pretty scooter! Temps stayed down w/ door still on, eh? That's good and the newer paint on the door matches perfectly too.

Your pic reminds me, today received 2 new Michelins for my smallie that tracking said would be here next Monday. All my riding has been on it lately and the tires look OKish but are elderly and one's still a whitewall. I better go down & put them on then maybe take a pic from your angle there to show them off.

Classic is going on this weekend but couldn't be bothered, went north to take in 156 miles of fantastic roads.

Back in town for a day, snuck out to the garage and cut down the gear puller, which worked its magic on the Sprint's OG motor flywheel. Didn't even damage it.

I got things pretty well torn down, but no obvious clues what the source of the rattling was. I'm thinking it might have been the fly side main bearing, as it sounds a little gritty when I spin it. Maybe a little rattle in the cush drive, but nothing too over the top.

All in all, it's a bit of a mystery

And I'm gone again tomorrow, so it'll probably be a couple weeks before I make any real progress since I still don't know what I'm going to need to order. Meh.

I have my 25+ HP LML motor in the Sprint, Brother E, so it's ALL good .

I want to get the Spring's original motor back in good shape to put in my Stella as a backup for the next time I blow up that LML motor.

I finally got the correct sized decal applied to my scoot today. I was hesitant for a while to put in on, in fear that I was going to blow up the motor. I bought a PX125 decal from SIP last year, and then just rearranged the numbers a smidge. Too bad gaining horsepower isnít as cheap and easy as this is...

Did you try moving the flywheel sideways/up and down before taking it off? These flywheel bearings don't seem to last all that long in the scheme of things.

It was solid all the way around. The bearing itself was new from the rebuild at the beginning of the year. I think it sucked up some metal from the seize, but that's all.

I only have two other clues right now. There was metal in the gearbox oil, although not a ton, and it's always had more vibration, especially accelerating and at half throttle, as compared to the Stella. They both have Clauss mounts. I had wondered if it wasn't to do with difference in frame thickness, but with the Stella motor in the Sprint, I don't have the same level of vibration.

I'll figure it out eventually, or put it all back together and get used to disappointment. It's noticeable just standing next to the bike, even while idling, though...

Thanks. This project was for the first day of kindergarten. Yesterday was the first day of 1st grade. It seems I can't complete a project as fast as you can. You got almost 3 done in less time for me to complete my 1 and a 1/2.

I've always said that the pre-P's are much more susceptible to vibration. Would love to know exactly why!

I know the feeling! But we canít always be shop rats, even though itís hard to resist the pull into the garage... More meaningful to be spending time with the kids as much as possible. Time flies amazingly fast with them!

What a nice dad to treat your darling girl to such a cool ride. Congrats on getting it ready in time this school year.

Nice.

It bugs me that the pumps usually have all the connections pointing different directions, making it almost impossible to make a neat installation.

Maybe I'm paranoid but with all that wiring under there, if you ever have a fuel leak your bum might go boom.

I agree that I too find it vexing that the feeds are different orientations.
In respect of the leakage and boom. I've done this type of location for years and not had a problem..... touches wood

Considering all the cars and trucks on the road today that have fuel lines going to a hot engine bay under the hood that don't spontaneously blow up, I'm sure your setup would be just fine.
