Love it! Looks like you went with Triumph carbs, triumph pre-EFI gas tank? How does it run- I'm assuming great, as it looks to be stock stuff? Fantastic looking bike!! What got you started on the switch? Wanted something different? Or did you have some sort of EFI failure?

Great to know this can be done with awesome looking results! Thanks for sharing!

the process wasn't so expensive and hard as everybody told me, just sold the efi parts and bought carbs parts!

for a complete conversion you need:

flywheel, main wiring harness, carbs and coils
in the 2010 version you have to keep the stock tps, in other version you can keep it or change it, it doesn't matter!

the rest of the work is just unplug the old and plug the new, not too hard if you have just basical skill!
now the bike work like a charm, the 2010 engine have some hp more and with carbs installed i have to change my clutch springs, now it slip in first and second gear!

Yeah, that doesn't make any sense to me. EFI from my experience will out perform a carburetor any day. If you aren't computer savvy, EFI is a deterrent when tuning which is the only reason I see going with a carburetor.

well they will if you use stock carbs but not the case if you go to flat slide carbs .Then the carb bike can make more hp then the efi bike that may change sometime but it hasnt yet .
