How to Change Sprockets on Hawk RPS 250

March 19, 2023 Hawk 250 19 Comments

This short guide will show you the steps to change your sprockets on your Hawk RPS 250 Enduro dirt bike. The sprockets I went with are JT Sprockets 45T and JT Sprockets 17T. You can purchase Hawk 250 Upgrades by clicking here. You will also find other Sprocket sizes depending on your needs.

Step 1. You will need to remove your rear tire and the cover for the front sprocket on top of the gear shiftier. There are 2 bolts holding the cover for the front sprocket.

Step 2.

The next thing I worked on was the rear tire. You will need to remove the 4 bolts holding the sprocket and the clip (red arrow).

It could be a pain to remove the clip if you don’t have the right tools for the job, which is what normally happens to me lol. I was able to get it off but it wasn’t pretty. I’m sure there are needle-nose pliers to make the job easier.

Put the new sprocket on and make sure it sits on straight and then put the nuts on and after that the clip. Check the sprocket after to make sure its not on a angle or misaligned.

Step 3. Once you have removed the cover for the front sprocket, you will need to remove the 2 small bolts and then turn the clip holding the sprocket until it comes off.

Once you have removed the old sprocket, put the new one and put it back together the same way. Rotate the clip until it lines up with the bolt holes and make sure its secured.

With the front sprocket I put on my hawk 250, I had to grid off some of the metal on the cover so it could be put back together. You might be able to put it back without grinding it but a few members have reporting having to grind the edge to clear it.

You can see below where I had to grind some metal off the cover case.

Disclaimer: I have no mechanical experience when it comes to working on motorcycles. Everything I have learned has been from either breaking it and needing to figure it out to get back on the road or watching youtube videos. I’m sure there are better methods to do some of the stuff I’m showing you here but this is how I got it done and it worked for me. Read at your own risk and if there is anything I can help you with, please contact me.

Changing out Hawk 250 Stator and Testing Bike

December 17, 2022 Hawk 250 1 Comment

My buddies hawk 250 one day stopped working, he is around 3500 miles. The hawk 250 turned on for a few minutes and then shut off. He was moving at this time and the hawk sat for almost 4 months before we had a chance to look at it.

We did the “quick” troubleshoot method lol. We swapped out the quick parts from my working hawk and he still didn’t have any spark. We watched some videos on checking stators and magneto switches and found it was bad. We got a new stator from therps.net website for $50 but now they have changed their prices and it costs more, not cool.

Here is the video we recorded while changing the stator out. It was fairly easy to remove the cover and get to the stator to replace it. You just need to make sure to take pictures of everything before you take it apart, its always good to be able to look at the picture and make sure you put it back together correctly. The mind can easily forget or confuse you lol.

Here are some pictures of the new stator we got and the old stator.

Getting the red hawk 250 ready for operation.

It’s very easy to get to the stator. You need to make sure to remove the small cover on the electric start. There is one more bolt behind the gears that are holding the stator cover in.

The below is the old stator. Make sure to take notes on how its installed and put the old stator and magneto switch back the same way. You want to make sure you don’t pinch the wires. Pay attention to how the stock one was set in there and do the same with the new stator and switch.

You will need to remove the wires from the plug before you will be able to remove the hawk 250 stator from the cover box. I used a flat head screwdriver to push the tabs and push the wire out. Remember to take a picture or write down the order the wires go into the plug. You need to make sure they are put back in the same order.

The red hawk 250 owner making sure she clean and everything looks good before we put the cover and new stator back on.

Once we got everything closed up. It took a while to get the hawk 250 started since it was sitting for a while. We replaced the gas, we cleaned the carb and put in a new spark plug but she still took a few kicks before she started. The battery was pretty much dead and we didn’t have a charger. I was kicking too fast and my leg slipped and hit the foot peg an this is the damage below. Excuse the white hairy legs lol.

This is a few days later. Looks really bad but it doesn’t hurt and by now its healed up more.

If you have any questions about this post, please feel free to contact me. I’m no expect mechanic but I will do my best to help you out if you have any questions on how I did it.

Hawk 250 Tire Sizing Guide

August 11, 2022 Hawk 250 4 Comments

Before I purchased my new Shinko 244 tires I had to do some research because any website you go to buy these tires, it will have bunch of different sizes and numbers and I had no idea what all that meant =). Doing some quick googling and research I found a website that I think explained it pretty well. I’m copying/pasting their content below and will link to the post under it. BEWARE: This website worked for me and the tires I got fit perfectly, please make sure you do your own research if you are getting different tires than the Shinko 244 I got, I would hate for them not to fit and you blame me =(.

The tire sizes for the Shinko 244 tires I got for my hawk are,

Front – Tire Size:3.00-21 51L
Rear – Tire Size:4.10-18 60S

Where to Buy Shinko 244 Tires – Click here to see the Shinkos tires added to my store. You will see the 244 sets and the 705. The 705 is more for people who prefer the street riding only.

Hawk 250 Tire Sizing Guide

Most dirt bike tires have a set of numbers that indicate the tire width, aspect ration (height) and rim diameter. Sometimes you might see just the tire width and diameter in inches (i.e. 2.50 – 10), and this is common with smaller tires.

80/100-21 Front Tire –

Tire Sizing Example Using an 80/100-21 Front Tire
Using a common 80/100-21 rear tire as an example; the first number, 80, indicates the width of the tire in millimeters. The second number, 100, is the aspect ratio, which is the height of the sidewall in relation to the width of the tread (100% of 80mm). The last number, 18, is the rim diameter in inches. So this tire is 80mm wide by 80mm high or tall and fits a 21″ front rim.

110/100-18 Rear Tire –

Tire Sizing Example Using a 110/100-18 Rear Tire
Using a common 110/100-18 rear tire as an example; the first number, 110, indicates the width of the tire in millimeters. The second number,100, is the aspect ratio, which is the height of the sidewall in relation to the width of the tread (100% of 110mm). The last number, 18, is the rim diameter in inches. So this tire is 110mm wide by 110mm high or tall and fits an 18″ rear rim.

Installing Spoke Skins Guide and Video

May 28, 2022 Hawk 250

Whats up fellow hawk 250 owners and future ones (what are you waiting for!). Today in the mail I got my new hawk 250 spoke skins I ordered from the hawk 250 shop, under the Spoke Skins category. I was excited to get started on these but first I had to take a quick nap to relax the mind haha. After the 2 hour nap, I was ready to get to work.

I would deff recommend doing these during the day when its sunny out and you can let the skins sit in the sun to warm up and loosen up. It was a pain to work with them in the cold. My poor fingers are still feeling it as I type this post. I also recommend cleaning the rim, it will make things a lot smoother as you will see in the video below. The front rim went a lot quicker compared to the back rim because it was cleaner.

In the video you will see me starting to clean the rear rim but the I got lazy and skipped it lol, but it gave me a headache of a time installing the rear ones. I’m sure if they sat in the sun a bit, it would have been easier.

Hawk 250 Pictures from Installing Spoke Covers

Some quick images from the install of the hawk 250 spoke skin cover protectors. This was a fun little project to do in the garage and it didn’t cost me a fortune. I really like the way it came out, I still need to tweak a little to make it a snug tight fit but we are almost there. Tomorrow I will finish this off.
