Hi, Wilfredo you will have less power it will take longer to get there but your RPMs will be less in high gear also the real answer to this question is way above my pay grade for this situation, I would call or visit my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry.
Good luck and have a wonderful day.

I don't have a tack on my bike but 80 is the top speed on my 04 Honda shadow 750 what can I do to change my rev limiter or increase my speed

Sorry, something is wrong here. Your Shadow should easily do 95 to 105 as top speed. Have a motorcycle shop check out what is wrong here. As far as increasing its top speed, you could change the sprocket to less teeth at the rear wheel (then increase the front sprocket appropriately), but then your acceleration will suffer.

How do I check them? I got some trouble code on 2005 Chrysler 300 3.5L. One of them is P0501. That means Vehicle speed sensor A range/performance. Others are about ABS sensors. Please tell me how do I fix...

Unfortunately the isn't just 1 speed sensor there are 4 one on each tire. Jack up your car one tire at a time, grab the tire on top and bottom and see if you get any movement without moving the car at the same time do the same thing for the front and back of the tire. Your testing for a really bad wheel hub. The speed sensor is located on the hub and the part that it is sensing is located on the axel generally looks like a bike sprocket that should help you locate the sensor. You can text these with a multimeter looking for the resistance. Small variation in reading are ok you will have drastically different numbers between the working and faulty sensors.

I need to change the rear gear sprocket, but don't know what speed the mountain bike is. How can I tell what speed the bike is.

Count the cogs, duh. You're going to need some help even after you know if it's 6-, 7-, 8, 9- or 10-speed in the rear. Special tools and 'how-to' knowledge. Take it to a Bicycle Shop an experienced DIY cycling friend.

To improve top speed,one solution is to change your gearing, via the chain and sprocket set up. To gain more top speed, you need to replace your rear sprocket with a smaller one, say about 5 or 6 teeth less. Also the front sprocket changed for a slightly larger one, usualy 1 or 2 teeth more. Note, that while doing this will give you a greater top speed, it will not make your bike more powerful. A power pipe, or aftermarket muffler would be a great improvement too.

I just received a sports bike for ecercise and model number is EDG 329u. Every time I try to ajust the peddal speed it makes a weird noise and It will not move the speed it stays the same speed. It is very...

You have the bike in a high gear. Assuming it is a deraleur type, look to see which sprocket the chain is riding on. If it is one of the smaller sprockets (on the rear wheel, not the pedals), put it onto a bigger sprocket by changing gears to one of the lower gears. As a side note, professional riders change gears many, many times during one outing. They keep the pedal speed at a comfortable speed no matter how fast or slow the bike is going. Anyhow, to review, put the bike into a low gear, particularly when starting out from a stop. If the bike makes a wierd clicking sound, or the gears don't change as they should, it is possible that your indexing in your gears needs some adjusting, or there is some other problem. Any bike shop will take care of you, as these are very easy to fix.
