New 44mm bore kit....now what?

[Trafficjamz]

ok i understand that i need gears to make it faster but with a new bore kit i should be going faster then 30miles and hr,,at least 35 it did 30 with out bore kit

Try using no air box and see if the acceleration improves. The 44mm big bore does not like the restriction of the stock air box no matter how many holes you put in it.
If no airbox/filter is an improvement over swiss chees air box, get a uni filter, it should help.

Also check for carbon build up in your exhaust pipe. It might be time for the campfire treatment.

If you were going 30mph before you will still only go 30mph But it should get there quicker

What size tire do you have? What size is you friends tire?

Different year sprees had different gear ratios. Is you friends spree newer than yours?

No, not true. Unless the engine turns more RPM, top speed will not increase regardless of displacement increase. To make it turn more RPM, listen to TJ.

Again you have no understanding of what it is that makes a vehicle go faster.

The bystarter is an electric choke.

Check for leaks around the bystarter where it fits into the carb.
An air leak around there could cause the problem you described.

Keep on rolling low.

You can't go any faster because you failed to acquire the gear set with the BBK.

1. did you refill case with oil when you replaced gears?
2. did you check engine for vaccum leaks?
3. what air filter or air box configuration are you running?
4. have you done anything to clean out your pipe?
5. did you install a new jet in your carb with the bbk?
