Hammerhead Buggy ATV Riding, FAQ, Tips, Maintenance, Accessories, and Modifying by Scout Dan Hammerhead with HH Motor Sports

We hope you will find this page informative, helpful and entertaining! One of our favorite places to ride is Black Mountain in Evarts, Kentucky.  See trail map.  Join the Harlan County Ridge Runners Club and we'll see you at the events!  Evarts has great food    Our favorite buggy pictures over the years show how rugged they are in all weather, all terrain.

We met Dan many years ago and he and his sons all love the great outdoors.  Dan found that he really enjoyed riding his Hammerhead buggys, finding all kinds of unique places "off the beaten path".  He rally does great in the mud challenges! Muddy Scout Dan    Once Dan retired from his day job with P&G, look out! 

 He loaded up all 4 buggys on one trailer , he quickly conned, I mean INVITED his buddys     scout out the hills, cave, tails & mountains of Kentucky and we dubbed him "Scout Dan Hammerhead".    

When the Super Sport 250 was introduced Dan decided to head out and see what it could do in the great Rocky Mountains in Colorado, all the way to Pikes Peak. SS250 in rocky mtns Not only did it perform well, but he also added a trailer to haul his son's dirt bike up to the top. 

Since Dan has had some very interesting modifications, SS250 silver no top  Ski's in Winter  He does his own maintenance, and finds lots of good Tips for buggy owners, he shares tips with everyone. Like, don't forget to keep your air filter clean (this is not Dan's, of course!) Clen you rair filter  and just HAVE FUN!

WELCOME TO THE REAL DEAL - SCOUT DAN'S TIPS            

TIPS "STEEP MOUNTAIN RIDING"

STEEP, CURVY, GRAVEL IN MOUNTAINS:   Larger more aggressive knobby tires help maintain better traction on both 150cc and 250cc buggys. 

Subject: Better Traction for the 150 cc Side by Side.  According to Scout:  "I ride on steep trails, gravel roads and found that the stock 150 cc  tires sometimes slip. I was always helping my kids and friends get  unstuck because the tires slipped and they were still developing their  drive skills on these types of trails. I also wanted to get better  traction on wet or muddy trails with ATV type tires that would fit the Hammerhead buggy 150cc rear rims.  Trail Wolf have a more aggressive knobby tire  pattern that have worked well for me. I use AT22x10-10, which allows additional rear end ground clearance.    The AT22x10-10 is the largest tire available to fit the Hammerhead standard  rear rim. Note:  I did bend the mud flaps out to prevent rubbing against the larger tire.  The additional traction you gain is well  worth it.

The Trail Wolf tires Trail Wolf tire   also work much better in the winter when we go riding in the snow.  Since these are a larger tire, I did compromise a minimal amount of torque at the rear wheels, noticeable when climbing even a small hill.  To make up for this, particularly on my single seat 2003 Hammerhead 150 buggy, I additionally made drive chain sprocket changes. (See High Torque Output from 150 cc Buggies 

Subject: Cross Bar Binding If you find the cross bars are interfering in your aggressive climbing, I have removed them on the 150 Models to avoid getting hung up in some thicker areas.  Note: applies also on the new GT250; however Super Sport 250 does not have the cross bar. 


Issue:
The drive frame on all 150 cc buggies has a support bar that goes  between the two rear shaft bearing plates. This cross bar loops down and under the rear axel sprocket and also supports the mud covers and helps support part of the rear brake mount.  After several months of riding, this cross bar will get bent from hitting rocks and other hard trail items.  On all four of my 150 cc buggies I have found that if this cross bar gets bent too much it will start to  put a side load on the rear bearing, rear brake assembly and rub on the drive sprocket. I have had  to replace one set of rear bearings already because of this issue.

Solution:
In order to eliminate this Cross Bar Binding issue I have cut off all  my 150 cc cross bars. This also allows me to install a larger drive shaft sprocket for steep hill climbing. 

Picture below shows cross bar removed and what it looks  like after you have cut the cross bar off.   Cross bar


Subject: Seating on Long Distance Rides For extra comfort when riding more than 7 hours at a trip, consider placing a cushion under your knees.   It helps on those very long steep grades!

Subject: High Torque Output from 150 cc Buggies  

Issue:
Climbing really steep trail hills with two people in my 2004 old Standard 150cc  Side by Side buggies was sometimes limited and scary. With two small kids this might be OK but with 2 large adults it takes some experience.  Just like learning to ride ATV Quads properly, it is important to practice first on how to safely back down a hill before attempting this at the top of the mountains. 

The 150 cc engine has the horsepower for climbing hills but the CVT and belt drive system are designed, sized and marketed on these buggies for middle of the road type driving. If you like to drive on  flat roads and small hills they are great fun. However, if you go out a lot on steeper hills the drive belts may start to slip under these types of loads. Weights or spring changes to the standard CVT and other engine drive parts will increase the rear wheel torque a small  amount but not to the amount I wanted for really steep hills. My objective for making the following changes was to be able to climb the same steep hills that most ATV's can climb.

Solution:
To maximize the rear wheel torque on a standard 150 cc side by side for hill climbing to a point that the CVT and belt drive do not slip,  the rear axel sprocket needed to be increased from 39 to a 54 tooth.  This change will increase the torque at the rear wheels by about 40%.  These changes will reduce to top speed of the buggy from about 36 mph to 28 mph. However, I haven't found too many dirt trails that you can  safely drive at 36 mph. So, the reduce speed and increased hill climbing capability has been well worth the changes for the more extreme type of riding trails I travel.

Here are the steps for making this change.

1. Cut off the rear cross bar so that a larger sprocket will fit.
2. Buy new or shorted the existing rear drive frame swing arms. The current swing arms limit the diameter of the new sprocket. Reduce the swing arms length from the current 5.125" to 3" by cutting out a piece in the middle and then welding them back together.

Warning: If you don't make this swing arm change and install the large sprocket, the sprocket will cut a hole in the engine block when you hit large bumps. Here is a picture of the changes.  Remove sproket

3. Remove the rear sprocket and take it to a company that sells and can machine a new mounting bolt pattern for a metric sprocket. The one I go to locally is Cincinnati Transmission (name may have changed) 6311 Wiehe Rd. Cincinnati Ohio 45237, Ph no. 1-513-731-6031.  The sprocket part number I have used on all three of my buggies is 52A54 which means it's a 52 pitch (Metric), 54 tooth sprocket.  When you order the sprocket have them also machine it for mounting on your axel. Give them your old sprocket as a template.  Sprocket sizes

4. When your new sprocket is installed, add a new section of drive chain to the old chain because of the larger sprocket diameter. Be sure you are using the same original metric chain size and type.

TIPS "NIGHT RIDING"

LIGHT BARS:  Clinton Glancy, an avid hunter, added a top light bar for his trip to Oklahoma.  He brought back 2 boars and a deer!  He hooked the lights to a separate 12V battery that can be kept inside a box on the cargo rack. 

Clintons light bar added to SS250

Another application for the extra battery is used for LED accent lighting, with a toggle switch.  The extra 12V battery is inside the diamond plate box stored on the rear rack.
