I work in a rubber shop where we also make kevlar rubber. I can tell you that you have to reheat the belt before getting the full power of your bike. They are so stiff they take a lot of power to rotate when cold, and this stiffness make them break more easily. All kevlar belts I broke and that I seen broke were broke when cold.

They are so stiff they take a lot of power to rotate when cold, and this stiffness make them break more easily. All kevlar belts I broke and that I seen broke were broke when cold. That makes sense, I will keep that in mind if I ever get a kevlar belt.  More parts came in the mail today, so I changed a few things. As usual I made too many changes at once, and got kinda aggravated in the process. I changed the stock reed cage out to a cage with fiberglass reeds from Racing Planet (about $40.00 dollars). I was worried that the steel reeds were going to trash the engine at some point. I also thought there would be a performance increase with the new reed block, but so far I have not seen any. Along with the reed cage new jets, and a 90deg rubber tube for the kart style airbox also came in. Since I had the carb off to install the new reed cage, I decided to work on the jetting a little, and also put the kart style airbox back on. I have had the lawnmower air filter on for a good while now, and it runs really good with that setup which consists of a 48 pilot, 96 main jet, and the air screw barely 1/2 turn out . I also changed the slide out the other day from a 50 to a 40, but I did not see a big change there. The only thing I don't like about that setup is that most of the "throttle" seems to be in the 1st third of the throttle range of movement, and the fact that it's also VERY loud through the filter. After all of the changes today, I am beginning to wonder if the 21mm Dellorto carb is just really too big to work properly in my setup. I think it just lets too much air in, and if I restrict the air much with anything, like the kart style air box, it just does not want to work properly, no matter how I jet it, at least so far. I really need to get the kart airbox dialed in so I can quiet this thing down, but I just dont know if I can make it happen with the 21mm dell. |

Forgive me if I've missed it, but do you have and have you tried a stock airbox on the Dell. I always run mine with a stock airbox, snorkel removed, for the 21mm Dells.

Sadly, the only one I have that is not total junk has a pretty small diameter intake. I guess it is past the time I should try it though. Ill pull the snorkel out, and give it a try tomorrow. What jetting should I go with? 35 & 92? And which slide, the 40 or the 50? |

Jetting sounds like a decent start. 40 is what I usually use.

Forgive me if I've missed it, but do you have and have you tried a stock airbox on the Dell. I always run mine with a stock airbox, snorkel removed, for the 21mm Dells. I just got done changing over to the stock airbox setup as recommended, and I can tell it is going to work fine. There is just a slight dead spot at 1/4 throttle but the rest seems pretty good as far as I can tell without doing plug chops. The fine tuning will have to wait till another day,because almost as soon as I pulled out on the road, a motorcycle cop that is known to be a ticket writing machine passed me and nodded, so I decided not to chance working on it today. When tourist season is over, the police get bored and tend to feed on locals a lot more. The stock air box is a bear to attach to the 36mm adapter I have on the dell. I had to use a heat gun to get it pliable enough to fit, and its is so tight a clamp is not needed. Is there a adapter for the dell that is suited to work better with the stock air boxes? I also need to order a new stock airbox, so if anyone knows a place that has good ones please let me know. As always, THANKS |

Used to be able to pick up airboxes from the ATVs on eBay as long as you don't need the snorkel, but they're all around $50 now.
I figured the 36mm would be easy. I use 38mm and also have to heat the snorkel a little sometimes.

On my Zuma:
47mm i.d. flexible spring hose from Canadian tire, enlarged the hole on the airbox, sealed with sillicone RTV, then connected to the carb. Works great!

I haven't been riding any for quite a while, due to the cool weather, and a 3 1/2 week bout with asthma and bronchitis. But today I felt good enough, and it was warm enough to get some stuff done that has been backing up. I recently ordered a couple Michelin pilot power pure SC tires. A 130/70-12 for the rear, and a 120/70-12 for the front. UPS delivered the rear tire yesterday evening, so today I took the pipe off of the scooter, got the rear wheel off and dropped it off with the new tire at a local shop. I paid $20.00 for them to change it over for me. It was worth it...this time. I guess I should invest in some tire irons and do the front tire myself when it comes in. We also took my wife's Nighthawk to the dealer and had a new rear tire installed that I picked up several months ago. Since they had the wheel off, I had them install a new chain. Total cost $203. Also worth it in my opinion. So much to do, so little time! We plan to ride some this weekend cause the weather is supposed to be GREAT! URL=http://s1070.photobucket.com/user/oldgeeks/media/Mobile%20Uploads/2002_zps67fa91c1.jpg.html]  [/URL] While I had the pipe off of the scooter, I decided to test fit the giant Technigas pipe that I took off of the vino I picked up a while back. Of course, none of the brackets I tried with the pipe came close to fitting, and since I didn't really have time to rig something up for a test ride, I just put the Technigas Next-R back on for now. I did start it up while the bigger pipe was bolted up, and I kinda liked the sound, I wonder how it would preform?  Should I try to repair the damage to the pipe, or just run it like it is?  On another note, I finally bit the bullet and bought a 2002 Tahoe with 164,000 miles on it. Interior looks great, and a mechanic buddie of mine put it on the lift and gave it his blessings. I hope I made a good decision, cause we pick it up tomorrow. I feel like I am paying a little too much for it, but time will tell for sure, sooner or later. Quite a big change from the Rodeo, and the Tracker we have been driving for the last 7 or 8 years. |

The tire irons are a good investment IMO. You'll save a lot in the long run. I used to curse tires when I used screwdrivers and pry bars but they aren't bad at all once you get used to it with irons. You can get a tire on and off pretty quick.
Looks like the header is a good bit larger than what the current one is so the bent part would be OK. Might be worth at least a quick attempt at freezing it out. You wouldn't have to fill too much of the pipe if you plugged the header end and angled it down. There is still a risk it could crack open at a seam, but it'd prob be fine.

I wonder if the wife would mind if I unload the freezer part of our side by side, for a day? I also got a chance to take a nice ride today so I could check out the new Michelin rear tire I just put on. All I can say is wow! What a difference a tire can make. I have never ridden a scooter with anything but a stock Duro or similar as far as I know. The difference is like night and day. 53 MPH is incredibly stable in the curves compared to the stock tires, and I haven't even got the new front tire put on yet. It is my opinion now that decent tires are probably the first upgrade anyone should make to their scooter if they can, especially if they plan to go faster than 25-35 MPH. I really like the Michelin Power Pure SC so far. But it would be nice to find a better than stock tire that is a bit cheaper. Price for each one of the Michelins was just under $50.00 each, including shipping. |

If you can't do the freezer, there's gotta be a night somewhere in the relatively near future that it will get below freezing outside even in SC.
I'm hoping the Power Pure will last long enough to be as affordable as any other tire with it's harder center compound. Not sure though since I got a screw in my first one almost immediately. Do you notice the transition of compounds as you start to lean?
