im wanting to get scooter to go between 65-70 but still maintain reliability

You bought the wrong vehicle.... I would suggest a "proper" motorcycle/scooter of at least 250cc displacement.

That's right.

Good luck with that. If you go with a cast iron sport kit, that's usually the most reliable and best choice for a daily rider IMO. The problem there being you won't do anywhere near 65-70MPH. You are more likely to see 45-50MPH. Adding a pipe should put you in the neighborhood of 50-55. With the right CVT stuff you could probably add on a little more. If you are willing to tune the cylinder you can probably do a little better and still stay reliable.

Those are max speeds BTW. If you are looking for 65-70 cruising, you're really far off and as reveen said you need to be looking for a motorcycle or 250cc scoot at least. My 103cc that can rev as high as about 12,000RPM with a custom made pipe, case porting, cylinder porting, CVT tuning, big carb and intake, aftermarket reeds, etc... is only good for 60MPH or so cruising and maxxed out at about 70MPH tucked on a long stretch. That thing makes power that's a far cry from what a cast iron 70 will do in reliable form AND I break belts all of the time with the transmission setup to go that fast.

They are easier to do maintenance and top end swaps on, but crank swaps and tuning is harder than the 4Ts IMO.

You don't need a new crank for sport kits. You don't really need to upgrade the crank until you start revving a lot higher.

-Malossi X-Kevlar Belt

The Polini Sport is a good kit. Should be 12mm for your scoot.

I'd skip the air filter. An open air filter is obnoxiously loud on a 2T. Louder than most exhausts. Doesn't offer much of a gain for all that noise. You're gonna end up needing to tune the carb with or without a new filter when you do the other mods.

The Street Exhaust Top Pipe they sell is actually a Stage 6 Street. Good choice for a scoot with a sport kit that will make power but won't draw attention.

Of course the problem with all of those parts is they won't get you the speeds you want. They shoudl be good for reliability, but not 65-70MPH.

As said earlier, skip that with a sport kit unless you need a new crank anyway (old one's done).

Most brands of rollers are OK. You use 15x12g stock. I prefer Dr Pulley sliders. They are a bit more expensive, but they really don't wear much at all and they offer a little better perfromance. Parts For Scooters sells all of the above.

Some say they see no difference with a boost bottle, others like them. Don't expect much, but I think they can help keep the scoot a little better in tune in different conditions (it won't react quite as bad to temp changes and humidity changes etc..., but expect no miracles). You can build your own really cheap...

-Polini Reed Cage

I have a Polini and a couple of Malossi reed cages and the Malossis are better made IMO. Don't expect a lot of difference in power. Not a bad idea, but not the best bang for the buck.

Stock. You shouldn't really need a different clutch unless you get a kit that needs to rev a lot higher than a sport kit. The stock clutch works quite well for most of us.

Just tuning the carb should be fine for the sport kit.

-variator???Dr Pulley Variator Kit

I like the Hoca variator that's a Malossi knockoff. You should use the 90cc version, with just means it's for the larger spline crank. Parts For Scooters sells them.

-torque springs???

[/url]

Autotech355 on eBay sells a kit with 1,000, 1,500, and 2,000 RPM torque and contra springs for a good price.

-wrist pin....whats good brand??

The wrist pin will come with the kit. The wrist pin bearing you should be able to get from whoever you buy the kit from. The generic replacements are usually fine, but Malossi, Stage 6, and others make them as well. There is a Wiseco from a dirtbike that I have used on 70s in the past too (B1043).

I'm really not a fan of their service and I'm not the only one. Search and read some reviews before you choose them.
