KEIHIN "PWM" CARBEURATORS?

Recommended Posts

I have been trying to figure out just wich carb to run for the larger more open style tracks I'll be riding on the ice this season. I tested a set of FTZ 35.5 carbs and they were pretty nice, but I need impossible to find mikuni tm34 body/bell gaskets, so they are on the shelf. I was gonna try a set of large Pwk/Strykers till my boss at work brought up the Keihin PWM. He told me It works nice on his CR 250 with an Eric Gorr port job, and runs super crisp bottom to top. Another of his claims is that it is super easy to dial in, and isn't as effected by climate change.

 

Any one here try a set of these on a banshee. I havnt ever heard of them put on a banshee, but I would be willing to try them out if any one has some positive comments on them.

pwm's are the more modern design i dont think they come in to many sizes tho but i'm not sure. i have only dealt with them on dirt bikes. a few DB's come with them stock.

 

ever consider'd lectrons?

Hmm, lectrons..... I love the thought of running alky through lectrons on my bike, but it just wouldn't work out for me in the winter. The power would be nice though. It seems that most people don't even bother with the lectrons for gas. Most guys with them tell me that they would definitely go Keihin or mikuni for if they ever had another gas motor. How do they work on gas compared to say a Mikuni tm/x or Keihin Pwk?

i love lectrons on gas. same simple design and easy to jet and set up. they usually make more TQ than similar carbs the same size. i personally dont know why they arent as popular. lectron as a company has been concentrating on the sport bike drag market but now i have seen they have a new owner and he is trying to market them wider again..

Not exactly a Banshee, just her cousin RZ. We are running 38s PWM and the bike is scary fast, very close to 90hp (350 cylinders) and 108 kg, fast enough to "power pass" a R6 in a short straight.

 

This is the bike:

And this is a on board video of our bike taken from another RZ (just enjoy how we eat 600s :cheers: )
