I am thinking about getting a small port job. Just something to add hopefully an extra 10 or 15 hp at the most. Is it possible to still use the stock carbs on a small port job. That is my problem, I dont have the money to buy bigger carbs and intake manifolds and bigger air filters. I need to use my stock carbs if possible.

You need to get bigger carbs when you start pushin' more air, not just making it flow smoother, or by adjusting the port timings by porting. You'll be fine, but sheck your plugs if you are worried about it............ :beer:

A few things. With 18cc domes, you're pushing some good compression unless you're at a really high elevation.

 

You need to think about having your stock crank welded so it doesn't separate.

 

Port the motor, and your chances increase again.

 

Free: Stock carbs

Cheap: bore stock carbs

Pricier..: 28PWK carbs.

 

I can't stand the stock carbs...they are prone to sticking... Even once you remove the TORS BS.

 

PWKs are so much easier to work on.

I am running about 155 psi in each cylinder on 93 octane. I am guessing my bike has around 45 hp with the mods that I have. I also thought about the crank. Probably needs to be welded before going with a port job? Thats the only thing I hate about adding hp. You add 1 thing and you will need to do 5 other things. Thats the price of going fast I guess!

i want to say the biggest you can get stock bored to is 30mm but im not 100%... call a few shops if they dont porting they can more then likely do them too...

 

although i have heard nightmare stories of boring stock carbs... but you never know it mght be just what your looking for if they work out ok...
