Any idea how much more power or torque could be expected with this mod?

yes

The reeds wont necessarily increase torque or Hp. The reeds will basically allow for more radical porting and prevent air/fuel mixture from getting spit back out the carb on the down stroke.

Tom Garcia is doing something similar on his GT250.

I did bring my "kiln" up to Ohio... Some "modern" transfer port, reed intake, and straight exhaust plugs with three sleeves....and a large crucible of molten aluminum...

At least for drag racing, is a water jacket that will stand up to city stop and go traffic in an Arizona summer really needed?

Kevin,

Did you notice the oblique reference there to modern transfer ports in Tom's post. That's where the potential HP comes from - additional port area and ports pointing in a different direction to aid scavenging.

And maybe a tiny radiator and no water pump might be a suitable compromise.

Tom , i also dont really know about that myself but i do know the water cooling allows a tighter piston / bore clearance .

I think Tom is questioning whether or not a smaller radiator might not suffice on a drag bike. Maybe a small radiator from a dirt bike might work for the short runs on the strip.

That would work for sure as i have a smaller and lighter radiator off a V65 Honda Sabre on my Yellow bike and it keeps things cool enough till i get in stop and go traffic and then the fan comes on . so for a drag run i can see a even smaller radiator working like off a dirt bike . http://cgi.ebay.com/ebaymotors/1991-CR5 ... ccessories

I have been trying out several different smaller radiator models from dirt bikes recently...so far, I like the KX60 which might get mounted on the RH frame down rails with revised brackets and modified engine inlet and outlet tubes to match the radiator. Then, I can get rid of the heavy radiator mounting lugs and use tabs welded to the frame rail.

I agree about the weight of the GT lower triple clamp...very heavy and it is on its way out. I am working on a viable replacement that will also allow smaller fork tubes. I have some parts coming this week and will have a much better idea if I am on the right track.

Im kind of interested in making some reed blocks. Ive got an early 72 motor with the studded head. And it so happens that im a CNC machinist. Ive made some rear sets and other various bits for bikes for a while. Ive also got good 3d modeling software at my disposal. I just dont have the knowledge of port timing and reed cages that you guys do. I would be more than willing to work with you and try this idea out further.

I'm not trying to hijack this thread, but...

Durgam, your signature is (perhaps) unintentionally amusing -

Novice rider,
Professional machinist,
Amature porn star.

So does this mean you get paid/filmed having sex with older partners, or that you're just more experienced than most?

The correct spelling is 'amateur' (if that is the intention

)

Cheers
Paul

I think his sexual escapades (?) should be left to the imagination. It provides a slight entertainment factor from his posts...
