I think I have finally made up my mind on what mods to add to my 2002 400 scrambler 4x4. I am going to go with HPD setup. I will get the pipe as well as a clutch kit. If anybody has any feedback about the HPD pipe and clutch kit or any of the HPD products I would love to hear them. Also should I shell out the extra cash for the aggresive clutch kit or will the regular one do. Also what is the difference in the clutch kit if I specify that I will be riding at high elevations.
Thanx for the info

 

You can get an agressive clutch kit without the helix for $90.00 but if you want the helix it is $150 for the kit. The helix is not a must to have. You will notice more if you had tons of mods to really make the helix work. I did not notice a huge gain with the helix so I sold mine to a friend. I have had other products but they dont come close to HPD products. Mine is pretty much a full trail mod and love it. Although HPD did not do my engine work. Bubba297 did the work for me and the work was a huge gain and he does tons of porting work for 400's. Anyways HPD is the right choice for sure.

 

A pipe and clutch kit are your two best mods....need a K&N and a modified airbox? that's the next best thing (PM me I have one for sale) HPD has some great gear, and great service to go along with it. You won't believe the difference. Go with the aggressive kit....mo power, mo power!!! [img]i/expressions/face-icon-small-happy.gif[/img]

 

thanx for the reply it is sounding like HPD is the right choice. I already have a K&N though, sorry I couldn't help you out on the sale

 

You may all ready have them, but if not, get the HPD V-force reeds.

 

What are reeds, what do they do, and what kind of performance will they add to my scrambler. Also being a fairly mechanical person will I beable to install them myself, where do they go? What is the cost of v force reeds, approx

 

V-force reeds are about $135. They are very easy to install. They go between the carb boot and the intake port of the motor. They replace your factory reed cage and reeds. Modquad has some for sale. PM him if interested. Here is an article on reeds. Reeds

 

HPD = good quality stuff, that does what it is advertised to do, as long as it is installed right.

Farmr

 

HPD it is what you want!,the best choice for the 2 stroke scrambler about engine mods and pipes,while if you're looking for suspension and chassis/sterring stuff,hot seat is a good places for that,enjoy HPD stuff,they make really your polaris faster,
an aggressive clutch kit will put more hp to the rear wheels...

 

oppss,not the least,high elevation????
you should talk to them first cauz mostly their clutch kit are made for 0 to 2000 feet elevation...you should able to run the 13.1 heads tough.
