72 carbs

I have a 72 GT750 all stock and want to change to the individual filters. what jets are recommended. also if I weld shut the transfer ports on the exhaust for the center cycler would I benefit or should i just wait for chambers?

I would start by going up on the mains two sizes and work down from there. You will probably have to go up one on the pilot jets as well.

As for the stock pipes, I would hate to see you weld up the cross overs and ruin a set of stock pipes. I would be interested in the stock pipes if they are in good condition.

Chambers would be a good additon as they will also aleviate the extra weight of stock pipes and increase your power to weight ratio.

Can you put freeze plugs in the cross-over holes?

Jeff, on http://kawasakitriplesworldwide.com/phpBB2/index.php, has mentioned doing something similar to this with a GT550. Don't know exactly what he used to for plugging the crossovers, or how it improved performance, but I'm sure he would explain it if you contact him.

I agree with Eric, I would not do anything permanent to a good set of stock pipes.

Freeze plugs have always been the preferred option to plug the pipes - or that's my take on many posts over the years. it is commonly held that blocking them shifts the powerband slightly so there's slightly more at the top end and less at the bottom. Think of it as a republican redistribution.

Chambers are the way to go for more power and an edgier powerband.

You could always drop the intake floor and raise the exhaust port roof. It will add a little power but will carve chunks off the bottom end and it will FEEL like it comes on strong - same effect as most eighties 4 into 1 4 stroke exhausts of that era.
