Is it reliable? Or strictly having to work on all the time

 

I love mine - no problems whatsoever. Just get the right cams and valve springs and run Race Gas.

 

My next mod will be internal, so I been doing a lot of research on it, rather only rip it apart once and do it right. I have not read one bad thing about the 14:1 piston. Only draw back I can see is that you have to run race gas which is not cheap. From what I understand there will be a few more engine options out there shortly. A 102 bore with the 14:1, or a 800cc all out big bore stroker.

Now all I need it $$$$

 

From what I understand, even the 11.5:1 piston requires 98+ octane. Here in S. Cali premium pump gas is usually 91-93 octane.

 

I was under the impression that pump gas was usable if cams were installed. Anybody have anything different? I'm speaking in reference to the 11.5:1 pistons. I have a RWR and was planning on using pump gas. I REALLY don't want to use race fuel or additives.

On a side note, I would think that a guy could pump about 1.5 gallons of race fuel to about 3.5 gallons of Super Unleaded and kick the octane up a bit. My math says that it would be in the 95 - 96 octane area...

Thoughts????

 

I think the confussion is when people say premium pump gas is okay for a certain ratio. The unknown variable is what is the octane ratting for the premium pump gas that you have access to. I know my pump fuel options are 87, 89, and 91. From what I am told other people are getting 98 from the pump.

 

i add 1 gallon race fuel to 4 pump for the woods 11.5, but that is just because i think the dunes works the engine a little harder than the dirt. but i have run just pump with no problems.

 

SANDMAN430. what octane is your "pump" gas?

 

Is there any advantage at all if you run race gas on a stock motor ?????????

 

No, there isnt. In my experience I have lost several bike lengths on the hill by running too high octane in a low comp motor, I dont think high octane burns right in a low compression motor..A few years ago on a stage 2 RW DS I actually felt the bike pull harder with 92 opposed to 100 octane (@2500ft elevation) At sea level the 100 octane worked better than 92. My bike runs too hot with anything under 114 octane. But the compression is a little higher than a stock ds.
