Soft Seize

Greetings:

I've enjoyed several months of trouble-free riding without so much as pulling off a spark plug, top speed of 69.9 to date. About a thousand miles on the Corsa top end. Going home from work on Deepinnaharta freeway, trying for a New Flash Record. Temps mid-70s and dry. After about a minute at WOT, doing about 61 MPH came a stumble, a sputter and the Dreaded wind-down. Tire didn't lock up but drag seemed in excess of normal off-throttle engine compression braking. I was able to stay off the front bumper of the Dodge Ram in my mirrors by pulling off across the breakdown lane and into the grass between the traffic and Service road lanes. Temp gauge read an uncharacteristically high 375 as I stopped.

After about 30 seconds I kicked it back to life - felt like normal and rode home without further ado. I have yet to pull the spark plug - which is a #8 and several months old - maybe 400 miles.

One likely suspect: The Treatland OKO carb donut I got to replace a cracked one isn't a real tight fit like the original one. I repaired the Spare one (SuperGlue and electrician's tape - just temporary...) and reinstalled. It worries me that I don't have a sure answer to the problem yet and groan at the thought of pulling plastics this evening. Guess I should check things out...

PG Long Death Rattle

Took off the saddle bucket to search for vacuum leak. None found, although there was a touch of oil mist on the starter.
My ultra-thin Corsa Alu base gasket had a little shipping crease when installed, so I'm attributing the seep to it.

Then I turned my amazing Wheelman Defuctive Powers to the PG Long, which had been getting a LOT louder for several weeks. I R a Smort Defective - a-hyuk - and deduced this might be an issue:

Yes a full-circle crack all the way around the stinger outlet. For the record this pipe has never EVER kissed a curb. It's ALL about the "skill" of the designers and/or welders at the PG Factory.

With my repaired carb donut, it's running as well as ever; 60 MPH in 1/4 mile or so and climbing. Just LOUD! I PUT SOME JB Weld into the crack just to buy me aome Quiet for a day or 2.

Anyone have a Loaner Arrow or SEF I can borrow while I hunt for a replacement?

Predictably, skillful Wheelman JB Weld repair lasted about 2 miles. I had cleaned the end of the pipe with carb cleaner but failed to finish it with Acetone. Carb cleaner leaves a thin oil residue, methinks, so the JB just flaked off in big chunks. That and I'm not sure the Epoxy base could ever handle Exhaust Gas temps when on the throttle.

Has anyone encountered the PG Long Death Rattle before? I'm thinking of having someone with welding skills build up a Cone O' Weld around the stinger outlet and giving it a shot of BBQ flat black, then calling it good...

I would TIG it for you for the cost of shipping it back... but I am sure you can find a good welding shop locally.

Thanks Ottoman. Yeah I have a guy...
Trouble is, if the original weld failed, there a possibility that the internal design predisposes to such failure. Aside from notoriously bumpy Deepinnaharta streets, I've never given it a reason to let go. And yet the crack remains... I can move it up and down about a mm, and it slides back and forth about the same. But it won't twist.

Who was it that posted the Split Beaver shot of the PG Long's Innards?

Never mind. Found it! Since my Guy's going to have to dig into this, is there anything I can do to quiet this thing down a bit? Anything I shouldn't do?

Could that stinger-pipe crack have caused overheat and/or soft seize? How?

Yeah I really didn't think so either, but thanks Bakaracer for the confirmation.

I think I was getting a little air leak because the replacement carb mount rubber from Treats didn't fit quite right. Diameter was OK but the location of the little inner ridge in the rubber isn't located where the Groove is on the carb spigot.
It seals at a standstill, but at speed on a rough road the carb bounces around and (I suspect) produces gaps.

Funny thing, but Benji doesn't have a standard CT-OKO Carb rubber in stock.
He gave me a break on a new CT with Carbon reeds, so 's'all Goood.

My Guy should have the Noisy PG welded up by Monday.

No further ado on the ride to work this morning; ran like a champ as always. My Guy did a nice job welding up the outlet on the PG Long. (Pic mas tarde.) Quieter now, but I wish it was closer to stock noise levels. Oh well, ya can't have everything. Or can you? I'd be willing to sacrifice a thousand RPM on top if I could quiet down the dB levels. Anyone want to swap a repaired PG long for something a little quieter? Baka, does the Sectional come anywhere close to the Long's performance? And quieter??

I will swap for a V8 YMS

Performance characteristics? Noise levels?

I had the JiangWayne 26mm pipe that was badged YMS ,and stamped V8 on the tailcone.
While the noise was close to what I want, I think it would cripple the Corsa too much.
Is yours that pipe, or is it the bigger Sectional version? Anyone using it on a Corsa?

I Finally had an evening to swap in my long-idle 7.58 gears! With the kind assistance of TrafficJamz's new-to-me single-bearing cover (Thanks, Dawg!), a new Honda-san "Late" cover gasket generously greased, and a new axle-end thrust washer, I set to work. Dumped most of the oil by leaning WAY over.

I've found a way to do the gears without removing the exhaust or any plastics. With a box-end wrench slid behind said PG Long, the wheel's axle nut can be removed without taking off the wheel itself. I just lock the parking brake and it stays put. The axle slides off on the cover side.

The old cover slid right off and the "Early" gasket remains unmarred. Gasket grease = re-usable. Even the dowel pins let go like they should. Experience has shown me the correct placement for my Tupperware catch pan. Nary a drop was spilled on my Priceless Persian Rug. The only minor snag was that the clutch shaft came off with its beaing instead of tapping out of it. Easily remedied at the workbench in the Boudoir. I'm a True Believer in the Bearing Freeze, Cover Heated Method.

Uneventful re-assembly with the new gasket and cover. I noticed an external difference between the Early and Late covers. The later cover has a beefier-looking top rear bolt-hole reinforcement compared to the Early one. 44 oil-can squirts of 10W-30 and a firm Wheel-hand on the axle nut and I was ready to go. The whole process took less than an hour, and remember, no oil stains on my Priceless Persian Carpet!

I installed my new Bando 669 belt, anticipating a little more stately take-off, and it's a good thing. Numerically 7.58 isn't much lower than 7.97, but the difference was palpable despite a pretty light load in the variator. My peak WOT RPM was down about 500, most likely due to the belt rather than the gears, but now it feels like Flash has the legs to achieve my goal: 72ccs, 72MPH. It remains to be seen... :wink:

This is the pipe....and it is on a corsa. Most of the noise on this setup comes from the Carb side :imo:

The v8 YMS is defiantly quieter than the PG long.

You should get the PG sectional like Fastplastic has.
It is about the same in dB but revs way higher :surprise:

Thanks for the honest appraisal. Is the Sectional. PG any quieter?
