I just bought a 2001 400ex and I am planing on starting off my mods with a timeing advance and a full exhaust system. That will definatly be cutting into my already tite bugget, so I was wondering if I can hold off on Race fuel for a few more months? LEt me know what you think-

 

I'd think that, without a serious increase in compression, race gas isn't necessary or even beneficial.To avoid possible detonation with advanced timing, you may want to use premium gas.

 

THanks, I was hoping that it wasnt going to cost me $6 a gal just to have a mod or two done to my bike. I also hoping that you know what you are talking about. I guess that there is only one way to find out. I think that just to be safe I will bring a gal or two of race fuel down with me. I have already have to drian my tank for another stupid reason that will remain unsaid so if worst comes to worst I will just add a littl ebit of race fuel to pep it up a bit.

 

Make sure you check the throttle adjustment on that new bike. Almost all the 2000 models had a lot to gain with just this simple act....

 

This is my first bike so am not sure how to accomplish this task. Is it something that I can figure out by myself or should I have someone else do it? My friends are pretty keen about these things so maybe they could help me do it. Is this going to me a noticable difference?

 

Yes, it's something everyone should know how to do on their own bike. There are instructions in the owners manual.

If your bike is not adjusted correctly you could have substantial top end to gain, definitely worth a check..

Do a search here in the Honda forum on "throttle adjustment" you will find that I and others have given detailed instructions many times. If you have trouble finding the posts, just reply back, and I will lay it out again.....

 

Right on, thanks again for all of your info. These are the kind of mods that I can afford right now. I will run that search and see what comes up. While I am ajusting this you said that I will be gaining top end, will this cause any low end lost?

 

No.

Honda sets the throttles to only open up 75%...

 

couldnt find it. If you have time to tell me the steps it would be much appriciated. If not I will look in my mannual.

 

So what does that mean, I shouldnt advance it?
