Bonneville America Forums Forums Technical Forums Performance Mods do I need to adjust jets

just put new raask straight through drag pipes on my 06 TBA,but here's my question, do I need to alter the jet's,some say I need to go up a stage others say no need, its just the dealers wanting more of my hard earned, what do all the experts think?

Yes, rejet.

Welcome,
I'm no expert, but all the info you need to DIY is right here.
And, if you have any questions you can get them answered
here, by folks that have done it before.

Without increasing the intake flow he might be okay, but it wouldn't hurt to rejet using the knowledge available here.

I say you should re-jet. If the intake is stock probably don't need to mess with the pilot jets but should adjust it with the screws. Probably need to bump up the main a little. If you open the intake side up to take advantage of the new exhaust then you should up both pilot and main. Not sure your elevation or the relative humidity so can't get too specific.

Yes, rejet

I have had Raask´s on the bike and rejetting is a must the bike will run lean if you dont.

Go up one step on the mains at least and pull the top snorkel in the airbox and the bike will thank you..

These bikes are set lean from factory and opening up exhaust and airflow will only make that worse and in the long run probably shorten the life of the engine if not corrected

....and why would you risk that?

thanks everyone,its great to know there's help here if needed. ( the pipes sound great by the way )
