just got me a dash150 scooter today used By bobthetechguy (Read 1,005 times)

Ended up finding a good deal on a 150cc.gave $400 for it, with 5k miles on it.Rides really nice, tops out about 45-50 with my fat @$$ on it. Got it up to 64 ;GPS confirmed down hill.

What sparkplug do I need to order? I want the NGK iridium just don't know the part number.

This thing also has the emissions control tubes running all over it. Is there any benefit to removing all that? Any change in reliability? Power? This thing has a huge round can exhaust muffler with a tiny curved tube inside the tip.

Tomorrow I plan on changing the motor oil, gear oil, clean air filter,spark plug,and a possible valve adjustment check.

What kind of mpg should this thing get? I only put about 60 miles on it after filling up and now I'm down to the red empty. I was driving it pretty aggressively though, totally loving the power difference from a little 49.
Having that extra power to spare in the 45mph range is nice. I noticed this motor really starts to pick up around 6600 rpm. It almost seems to lug at 4300rpm like Tue weights are too heavy. Of totally sacrifice the last 10mph of speed for more low speed takeoff power.

Sorry for my novel, just haven't been on in so long and had so much to say.

Hey alleypoop!

NGK C7HSA. You don't have to order a plug. Take the old one down to the auto store, they have them in stock. The R variety is resistor, that's only if you have a stereo but it doesn't hurt anything. Leave the washer ON. The factory gap is correct, don't mess with it IMO. That's great you want to baby your scoot with an iridium plug. I have swapped them out with conventional many times and just do not see a difference. But if you wish: CR7HIX

The pollution devices are passive, meaning the process does not force anything to happen in the engine and therefore they do not affect performance. The vapor canister works off of vacuum and simply draws gas fumes off the tank into a canister. It will affect performance if the check valve gets plugged up in that your scooter will stop. Here is how it works:

Here is how you get rid of it:

Eh? How about them charts kiddies??!!

The PAIR system draws fresh air into the exhaust system AFTER the exhaust valve. So it does NOT affect the performance of the engine IMO and I'm right. Seriously, it does not.

Here it is:

Here is how you get rid of it:

Of course it's better to block off the inlet to the exhaust port with a plate. But it's been my experience that if you plug the rubber tube heading into the check valve it works fine (sorry Sprocket).

Thanks. Now I seem to have a new issue, the front wheel bearing is about toasted.I can hear it starting to chirp.

Pop the axle nut, pull the axle, pull the wheel. Pull the dust covers and make sure the bearings aren't fragmented. Put some high temp grease on the bearings. Torque to 40 FT/LBS!! That 80 crap smashes the bearings. I've run mine at 40, all of them except the SYM, and never had a problem. I did at 80 though. If they sound OK after that and the wheel tracks true you should be OK. They may have just hit that with an impact so who knows what it's torqued down to. Do you need some pix?

Here's a page putting it back on, that should help.

I got the wheel off but couldn't figure out the dust cover . I pulled it back some and smeared grease in all in the bearing and shaft. It didn't make any noise at all today on my ride.I rode the hell out of it today, clocking over 200 miles in just an afternoon. There is lots of beautiful scenic byways in Arkansas that are legandary 2 wheel riding routes. Twisty curvy steep roads, road side historical landmarks.Its amazing how much history is being forgotten about when everyone takes boring straight highways in their big giant SUV's.

The only problem I have now is I only get about 90 miles per tank. Is there any big tank options? , other than strapping a couple of jerry cans on my rear luggage rack.

My 150 has a one gallon fuel tank and on a good day gets 75 mpg. The only option I've ever seen is a tank that straps on the rear luggage rack.
