I have pro curcuit pipes, pro flow kit, air box mods, and jetting done to my banshee. It makes really good power but I am interested in increasing my low end power as well as my useable power all around. If anyone has rock solid facts on products that will help let me know. THANX

I have been using the Trinity CV manifold, single carb set up for years. It gives me instant acceleration, power is smooth and throughout the power band. Jetting changes are so easy. I ride at 5000-8000 ft. altitude. No engine mods, FMF pipes.

 

bump the compression up a little (shave the head or get a cool head) and maybe change to a 13 counter instead of the stock 14. You should now rip down low. Yes the single carb *will* increase the low end, but takes away top...and also costs lotsa $$$, but if you have the $$$ and ride in seriously tight areas, go for it.

 

Want arm ripping low end. Get a trinity 420cc kit, (regular rod for more low end) a pro mx port job, and an after market trinity head. Cost is a staggering 1400 bucks for everything, but my gawd, it's an arm ripping, rock and sand throwing near insane setup. Besides that it goes way fast too!!!

My best friend just did this a couple weeks ago, I was so impressed and in aw that I over nighted my jugs to trinity yesterday for the upgrade.

I have a prodesign cool head with 21cc domes if you want to try one, I'll sell it cheap too. Like 200 bucks, compared to 280 new, and it's only 4 months old.

 

The best bang for pretty cheap will be to put on Boyeson Rad valves and a coolhead with smaller domes for more compression. I have this setup on mine and race MX with it without any problems. It has tons of low end now. You could even change the sprocket but that will lower your top end. The rad valves and coolhead will help lowend a ton and also help mid an top at the same time a great deal.

 

All I can say is get some flat slide carbs. This will give instant throttle response which will improve off the line performance. I went with 28mm Mikuni's. They come with everything you need to install including the twist throttle, an assortment of jets and even grips and fuel line. The difference is amazing compared to the stockers. Blip the throttle and the wheels are up. Later.
