Dear Motorhead:
First off I’d like to start by saying what a huge fan of DirtTrax TV I am. I have a question about my ride I was wondering if you guys could help me out with.
I ride a 2010 Honda 500 Rubicon, which is an incredible machine but even as you guys have stated has a number of drawbacks.
The issue I’m having is is it really worth the investment of purchasing a muffler, air filter and new jet for the carb to gain hp?
Everybody I ride with tells me to make these upgrades to my bike, but I was wondering is there any proof these investments will actually give me any gains?
Thank you for your help and keep up the good work. I look forward to seeing some new episodes on OLN.
Thanks for your email!
The Honda Rubicon is probably one of the least modified ATV’s and for good reason. Since the Rubicon uses a hydrostatic drive system there is very little if any return on engine mods.
The hydrostatic drive system limits what comes from the engine in a pretty profound way. A pipe will make more noise, however I have my doubts about it making much of a performance gain. Same for re-jetting and a low restriction intake.
The hydrostatic drive system is a “fluid coupling” essentially there is no mechanical link between the engine and the wheels other than pressurized oil.
If you could modify the hydro pump and drive motor you might be able to transfer more power, more efficiently however, as of this writing – I have heard of no such modification being available.
Hope this helps,
Motorhead Mark
