Im curious as to how 1st gear is? i have a 70t rear but if i do the 30t front will 1st be terribly shorter? Right now i do all my wheelies in first and sometimes hit rev limiter sooner then i like (mainly stock bike) so i run out of steam, or would i be able to clutch it up in second with ratio change?

 

Alright, I'm convinced.

I think I'll start with the 30t pulley. If I can find a stock 68t or 70t rear pulley cheap enough I might do that at the same time. I've found stock black ones, but I have a silver and would prefer to stay with that.

I considered the Evolution 49t clutch basket, but that's just out of my price range.

I read HD Pilots excellent thread so I know about the MF'ing nut. I'll have a new one ready to go.

I'm assuming I'll be able to reprogram the speedo with the Thundermax, but I haven't really looked into it yet.

 

According to the gearing chart on the Andrews website, with a 30/70 you'll be running 5650 RPM at 40 mph, where with a 32/70 you're about 5330 RPM at 40mph. Not sure if that answers your question...

 

In the TMCC there's a speedo calculater. A couple of different ways to use it but I found the most accurate was to use actual vs. indicated speed. To get the actual speed you can use a GPS. I don't have one so I used one of the radar type speed limit signs around here.

 

Yup it's real easy. That's the way I did it too. Hardest past is to get the GPS stuck to your bike....after that it's simple.

 

Is it hard to R&R?

 

That helps man, thank you.

 

Just have to ask. Is this pulley swapping mainly for baggers? or does it do well on lighter bikes as well? I have Andrews 48h cams with other upgrades on my Softail (96 engine). It is as fast as I need it to be for now. But what would I gain with the change in gear ratio? Faster off the line? More roll on power? What are the trade-offs or downside if any?

 

You say you have a 70 rear and you're thinking of 30 front....so do you have a 32 in the front now? That's a 4 tooth jump, which needs a new belt.

You can only jump +/- 2 teeth w/ stock belt.

 

I have an 06 so its a stock 70t rear.
