@Bluestoesonnose @Glynn123 is correct, front hubs are very different. The only way you could have two sets of wheels and one set of brakes is by swapping the forks from another bike like a KTM. As caliper brackets to convert enduro brakes to larger SM brakes are more plentiful with KTM's. You would also need a custom spacer for the headset and you might have to fanny around with the wheel spacers as well, but they are relatively small problem's to fix if you plan on achieving your goal.
@Bluestoesonnose So the VHSA Carb was standard on the TZR Belgarda models that ran the 3MBP barrel. Which was a modified 3MB setup. That was my logic behind carb upgrades.
@Bluestoesonnose If you can you should do some dyno runs with each head on, just to get a clear picture of the difference each head offers and share your findings. As that will give us all a direct comparison and clearly show the benefits each head has to offer. 😉
@2stroketerry thanks for the kind offer but my head and barrel are on their way after a call to Mick. Seems for the kind of time I'm looking for a bigger carb isn't required
@Bluestoesonnose Wise call - A stock bulb would ensure that you can track down any problems you have, without changing anything else or maybe adding anymore to the mix for-sure. :thumbs_up_medium-light_skin_tone:
