Octane New carbs!

speedysprocket · Oct 31, 2011

Finally found some carbs I think I can use on my Octane! First generation 46mm Novis! Anyone have experience with them and a guess as to where I should start for jets? Right now, only things not stock are V-Force II reeds, Watcon timing curve, and I started boring the manifold/head pipe out.
Thanks,
Alex

Used Novis recommendations, and it's a bit rich, but is much smoother through the whole powerband... Also cut my run time in half... Guess I'll lean it out and try some more tomorrow...!

How did you make out with tuning ? did you have to replace the intake to accommodate the carbs ?

Have to run a different manifold. Carbs run great!

Mike D · Feb 26, 2012

whats the make of the manifold you are running ? did you notice a huge difference ?
thanks

Have no idea who made the manifold, someone did a lot of welding on it at some point. Just gotta wait around to find a used one.
And it made a huge difference. Woke up the bottom end and mid range is better too!

So what do you have to look out for? kawi manifold or yami? Whats involved in putting mikuni's onto a polaris motor? Can the intaki mani be modified to fit Mikuni's? SBN 44's actually..

the 777 uses a 700 intake manifold,so the mikuni style intakes for the 1200 stuff won't work.stock octane carbs are only 38mm to start with,not 40mm as listed

There are production aftermarket as well as home made intakes out there. No yamaha or kawasaki stuff. Just have to keep a look out. Someone on PWCtoday has several sets.

the 96-97 hurricanes ran 700 motors with keihins.somebody made intakes for them to use mikuni's.bruce at wetwolf would know who.i can check my hot seat catalog to see if they did

That would be great! Any little info will really help me out, as there ain't much to go off here in aus!
