Put the boot on and its finally done. Any quicker now the jetting feels good? Should be making 70 fairly easily.
I'll bet its your commuter bike until its sold.

It's not much quicker, I think if it were staying I'd drop the barrel like you suggested and try the 24.24. But it accelerates nicely in the lower gears. It's a pleasant bike now, but the hills could be better in 4th.

Should be pulling in 4th like in 3rd. Barrel is too high. Your measurements might have not been so far out after all.
If your bored, slip off the cylinder and drop the base packer at least 0.5mm and add the same to the head gasket.

Yeah if I had one I'd use a stock head without 2mm off of it like mine has. Then I could drop the base to a standard gasket and use the 1.5mm head gasket, would be ideal. But alas I'm not loaded with time and have 2 potential buyers lined up for Saturday.

If you have 5 or so stock gaskets, then put them all on in a stack. Leave the head and drop the squish. Sure it will sell is just what people want now.

So today I had a prospective customer who wasn't totally decided when he left, but liked the bike. He complained that it didn't run lean in first, and that the front brakes were soft. Right on both counts he was, as I saw when getting back on to look at those with fresh eyes. The jetting was cleaned up by going to 45/140 idle, which still was best at only 1.25 turns out, so might want to be smaller yet. I also cut the main to 122. The front brake cable has been long forever, and I kept meaning to cut the outer. Off came 4.5" and the action is much improved now. I don't know if he will come back, but I let him know. If not, the bike is still better off for his visit!

Whats the full jetting now? If you can't run the 55/160 then the main jet is still too big. Need a bigger jump than 122. I would go to 118 and see if it feels better. I know you like to be cautious but if it is lean it's ok as long as you don't hold it wide open for long.

When I was rock screening at the beginning I felt power up from 120 to 124 main, I think we are close. We will keep on it till the end.

120 main loses off top speed in 4th, 122 is where I leave it, with the 45/140 it is much improved for low throttles and rpm.

Twice I have had boats. Probably never again, as long as I remember the relief when selling them.

Wonder what the new owner will do with the 200? MHR?

Probably chuck it on, fiddle about with some jets for the afternoon, and enjoy the hell out of it for the next 5 years!

No, I'm pretty sure the new owner will not put an MHR on, he's the target market for the detuned bike - new to vintage Vespa but was excited to get a nice looking P. He will love it as we just made it.

And sale complete. The detuning was definitely the way to go. Once I get the Malossi kit sold, between the bike and the parts sales I should easily clear my original target price for the bike, and I'll still be holding the PWK carb, MRP manifold, S&S clutch cover, and banded clutch basket. Not bad, I'd say.

Congrats!! Nice work! Sounds like you'll make out even better than planned.

Thanks all, now I can get to shopping! Looks like 2015+ is my target for the GTS, as I would like ABS. I've seen some good deals, pretty much you can wait and swoop. The best I saw was a 2018 Sei Georni for $5k with a couple hundred miles on it, loaded with accessories. Sweet deal, and I couldn't do it as I hadn't sold yet. That green is awesome.

Anyone interested in my old P200? The buyer contacted me to see if I want to buy it back.

Per the current owner:
Quote:
Hi man thanks for responding, condition is quite good, new tires, all working and top shape. Been sitting for two years.
I sold it to him in 2019, so he didn't put too many miles on in the interim. I'm guessing carb clean, maybe tank clean if it's been sitting. But the engine was fresh and stock(ish) if you read through this thread you will see how it left me.

It sounds like this isn't as much a project as I'm looking for. It is probably more suitable for someone who is looking for an "almost" ready to ride scooter. Thanks for the info.
