Tri Z Engine Build

[El Camexican]

The longer swing arm will need a stiffer spring due to leverage and chain torque. (Contact me, I will help you out)

When the swinger is completed I'll shoot you an email with the numbers.

I will find that C12, I just need to get off my butt.

You may consider running AVgas

I ran a lot of 100ll successfully in my old lt250. I don't remember the comp ratio anymore, but it trapped 215psi with a 190 port.

Don't worry about the chain there have been dyno tests performed where the best non o-ring chain vs. the worst o-ring chain was less than 1/5 of 1 horsepower.

I bought DID ERT2 once thinking it was gonna gain performance. The chain was garbage after one dune trip.. Been using sealed chain every since.

O-rings rule in the dunes.

Where have you been, kinda quiet on this forum lately, no?

Most of the heavy hitters in open are running 4 snows. I bought a set for my T5 but didn't get much testing done because 1) I finished the build there 2) We had to jet it 3) a couple hangovers of epic proportion and lastly 4) the monsoon. The few runs I made they hooked really well but we're a little too tall for my already tall gearing, si if you go this route I'd bring some different sprockets to try. And don't be the last person at the Choo tree

El, as you may know, just because one dyno test may have shown only 1/5 th of 1 hp difference in the test mentioned, it doesn't mean that it is not possible to gain more than that by using different chains then the ones they tested . . There may have also been errors in their testing method . . I have seen errors in various testing methods dozens of times before . . Tests are only valid if they are repeatable, and the fact is that it is absolutely possible to "free up" more than a paultry 1/5th hp by using a lighter chain and contrary to what has been implied by some [or one] the amount of gain I mentioned absolutely is achievable in some instances.

In addition, power can not only be gained by using a light chain as opposed t a heavier one, the lighter chain also reduces the weight which in turn increases the power to weight ratio . . Obviously the amount of change in this instance would be extremely small and therefore not worth "worrying" about in your particular case, it does exist as you know, and in some cases at Kawi such as the works MX and Road Race bikes, we actually spent a LOT of time and money per ounce reducing a vehicles weight.

Having also seen many dyno tests, including ones we did at Kawasaki, I can say for a fact that it is nearly impossible to accurately determine the cause of such a small difference in hp because of other variables such as engine temp and dyno error and operator error etc. One thing that must be done when trying to determine the cause of such a small difference in hp is to use a sealed, climate controlled dyno room where the temperature and humidity can be controlled . . The atmospheric pressure also affects hp and it can change enough from morning to afternoon to cause a slight difference in hp, however, most dynos are able to correct the hp numbers based on the different factors IF the dyno operator puts them in.

I have seen several cases where a dyno operator simply entered incorrect factors which were then shown on the dyno sheet . . This is actually not a big problem if one is only using the dyno for a comparison test between different parts or settings, however, if the same bike is run on the same dyno under the same conditions but the operator then uses the correct correction factors, the bike will miraculously appear to have either gained or lost hp . . Also, the readings from wheel dynos are not as consistent as the ones from engine dynos because different tire pressure will alter the hp rating.

For these reasons as well as others, it is sometimes best to get try and find info from an another source when one looking for something just to see if both sources say a similar thing . . Obviously there are several mfg's that say their product is better than everybody else's and in some cases they even say it has been "proven" to be by an "independent" lab, but I think that most of us know that Dos Equis really is much better than Corona.


Here's a dyno test where all they did was oil the chain and they "freed up" 10 more hp, so heck, just oil yer chain and grease yer bearings and ya might "free up" as much as 15.

El Camexican, Glad to hear you will be at TF this upcoming year! It is an experience you wont likely forget!

[El Camexican]

Ask Pedro Gonzales.

Already asked Sr. No dice.

I'm pumped man, is is going to be a blast!!! I figure if I have just one drink with each of the people I hope to meet... I'll be drunk.

I wonder what they run?

Good question. I didn't ask, but I assume Pemex "roja" like the rest of us. There are guys that have it here that have race fuel, the problem is getting it without a connection.

A lot of people have died or been injured producing and refining that fuel. Pemex safety policy is like that of the Panama Canal trenchers.

And then you don't get any tire testing done

hmmm...should I beer test, or tire test...beer...or tire . . I think I'll have another beer while I think about it.

Hey El, if you drink enough, you could probably run these on the back and it wouldn't make much difference.
