Welp, had this helix for a while now. It's been my winter project and now its almost complete!
I'm hoping to get this thing mechanically sound enough to become my daily to work and back. (Gas prices ya know)
(Boring backstory ahead)
I got this helix last year for a steal, 300$! It was a basket case but I had high hopes for it, I needed a intake chamber manifold (luckily eBay came to the rescue for the first year intake, 19$) I cleaned out the carb and it fired right up! 30$ for a new battery and if was off to the races!
Currently it still runs good and does ride fine.
However the top speed is rather poor (60-65mph) and sounds like a rattle can when accelerating.
Today I dove into all the nitty gritty of it. It needs a air filter BAD (Im surprised it even ran, filter was so clogged up with dirt and mouse poo you couldn't even tell it was there)
Belt is still within the service limits (21.5mm) however, I ordered a new belt to keep just incase (gates powerlink, it was 13$)
The rear wheel had a wobble and I thought the wheel bearings were shot, turns out the rear wheel nut was only hand tight, (got very lucky here, could of ended badly if that would of fell off going 65) doubled check all bolts for proper torque.
Muffler needs some addressing, it's missing the middle gasket piece and sounds like a tin can. I'll see if I can get the radio overhauled and working (only thing it does is turn on and set the time to 12:00, won't respond to any button commands) Overall, should be a interesting build!

Nice project you got there and a great deal to boot! I always wanted one of those, I even bought what I thought was one, but it turned out to be a krappy Chinese clone! Never buy a scooter or car in the dark

The design didn't age well but they are well made scooters. They would be a great replacement for my recliner in the living room.

They look cool naked. Not all scooters look good without clothes on.👍

Mrs Bud 10/06/22 you are not going to pull that engine apart and put lots of new bits in it, are you?

Installed the filters and exhaust gaskets Monday, the cover was missing the element so I'm glad I bought that (probably didn't need it but for 2$ it's good that it's there now) exhaust gasket was a PITA but managed to get it done in a record 2hrs lol
Seems like it has an intermitted spark issue. If I leave it all day it wont start (and no spark when checking) seems like the CDI box is going out (i can get it to spark again once I hit it with a screw driver and spray clean the connections down. after that it'll run and restart all day without issue (wondering if once it starts and gets hot, everything works the way it should)
but currently, it accelerates much better than before. With the rear wheel fix it now handles a lot better too (before i was scared to lean it over, now I can almost scrap the muffler) It can maintain 65-67mph @wot with the stock belt on there I suspect if i put that gates one on i should be able to hit lower 70s.
