Re: how to gain power from across
Here's one way!
On peter's across site,

www.hyp4r.com/mct/across/across.htm

...he mentions that you can put a GS 500 engine into the across. Would love to see that! Anyone have further info on this?

I've heard of the GS500 conversion, but really, it would be so much easier to buy a bigger bike that will have the uprated suspension and brakes to go along with it.

Re: how to gain power from across
There has been a guy who has done porting and polishing of the head with some excellent claimed results. If you search through the threads at groups.yahoo.com/group/suzukiacross you should be able to find more info.

Knocking out the baffles in the standard exhaust supposedly increases your output around the 14,000-16,000rpm mark. Of course you'll have to deal with the extra noise. I'm unsure whether there is a performance hit lower in the rev range but I haven't heard anything bad. Again you can find more on this by searching the threads at the hyperlink provided above.

Hey Ivan, do you know if you have to cut the pipe to knock out the baffles? You would have to wouldn't you? I wouldn't mind a little more noise from my beast, but don't want to buy an aftermarket pipe as I'm selling the bike within a few months anyway.

Thanks

Re: how to gain power from across
Are you sure that the GS500 motor would be an advantage over the across motor. Hmmm... not sure myself. They aren't real powerful really. I read it only puts our 43-45 horspower, probably has more torque.

Anyway just a thought

Knocking out the baffles doesn't involve any pipe-cutting. You just need to punch holes in the baffles (hammer on a screwdriver or if you want a nicer finish, powerdrill with appropriately sized drillbit).

I've got the images on my website at www.geocities.com/krazyives/bikes.html. Follow the link pertaining to the "exhaust baffles".

Credit to one Bryce Girdler for provision of the pictures and instructions on how to perform this modification (see groups.yahoo.com/group/SuzukiAcross and search for a "baffles" in the threads).

Re: how to gain power from across
dont do the gs500 thing. has anyone really done it or do they all just talk about it? have fun on the across while you can and sell it for a bigger bike. a bigger engine would ruin the across and i bet a gs500 cant rev to 17000rpm!

Exactly man,

Why bother tinkering with the Across anyway. They are perfectly good enough as they are. 

It's all about cornering people, just practice and practice.

A brief comment to add in closing; In a recent chat with some guys at Action Suzuki they stated that they knew of a really good rider that blows away just about every bike up the twisties of the old road (pacific hwy) with his bandit 250. OK so the bandit is a bit quicker than the across with the variable valve timing... but the moral is that on corners it's the riding ability that counts as much as anything, and that this type of suzuki is a very good handling motorcycle.
