jizz99 wants to know Dino or Syn?
Evo Hop-up

I want to get more power out of my stock 97 Fatboy. I just bought a Big Sucker air cleaner kit. Is a dynojet kit worth the cash or can you get equivalent results just by changing the slow and main jets? The exhaust is stock with the baffles drilled out - I'd consider buying a set of V&H Big Shots Staggered if there is an appreciable power gain. Is a Screamin Eagle ignition module worth the money?

Hello jizz99, dont know for Canadian spec bikes back then but changing your rear wheel sprocket from 65 to 70 tooth gives noticeable gains on off the line performance.
The dynojet kit will get you a few hp/tq numbers and make the cv more responsive.
Bassani Pro Stock stepped pipes are what I would order for the exaust (bearing in mind I dont like Thunderheaders and most of the 2:1`s currently available)
Even if they do give a few more horses in the 2000/3000 rpm range--- the rear pulley/Bassani`s will make up the difference.

Crane Hi-4 ignition with single fire coils and running in single fire mode smoothed out the motor----was pretty well the most popular ignition mod back then also, showing improvements in driveability.

Next step in real performance is of course heads and cam and cv upgrade----the cv carb is as good as the mikuni and s&s when boring out, rejetted etc. and will most likely work out cheaper.

My old 95 Fatboy ran Dave Mackie heads and Woods W8 cam but was re geared to suit the cam and it boogied.

Anyway, hope this helps,

All the best, Ozzie
