You must of lost considerable acceleration tho right.
No more power wheelies?

Also have you considered a meth tank to keep temps down?
Any H2 owner who's still riding around on stock 18/44 needs to try one with higher gearing. It's so much nicer to ride. It's isn't simply a case of gearing it up for LSR events, it's better on the road too.

The bike pulls 19/41 and 19/42 just fine and will still pick up the front wheel on the throttle until it's in fifth gear. I can't use 100% throttle until then. So the short answer is "No" the acceleration is still very strong. With 90 mph available in first and the top of fourth gear around 170 it still wants to wheelie and that's enough to leave almost anything you're going to meet for dead.

The only people to benefit from low gearing are quarter milers and they will need an extended swing arm.

I have considered an intercooler but so far I've kept it stock because of class rules.
Potentially cuz your not reviving the engine out cuz of the taller gearing does it help keep the boost temps down allowing for longer time WOT?

Nothing as scientific as that Richard. I arrived at 19/41 and 19/42 for land speed racing because these were the ratios I needed to do the speed I reckoned the bike could do in a standing-mile with the available engine power and a 13,000 rev-limit. Put simply it was "what's it likely to do?" and gear accordingly.

Everything else, including how much nicer it is to ride with taller gearing, is a by-product of that.

Hmm maybe I’ll consider it thanks a lot
Lower rpm levels cuz of taller gearing
Means lower boost temps cuz of lower rpms needed to reach high numbers
