Trinity 2-1 or back to stock carbs

[TrickShee259]

Here's my situation

 

I have a '96 bored to 382, boyesen reeds and spacers, wiseco pistons, cool head with 22s, Dyna ignition, full Paul Turner Exhaust and a Trinity 2-1 carb kit with the 35mm Keihin. My bike is set up for motocross which is why i have the 2-1 kit for the good bottom end however I want more power for the dunes. Dual carbs are a pain to deal with for me so i don't want to race on em since i travel and have to rejet a lot. My question is would it be worth it to swap back to stock carbs for the dune trips? Trinity claims a 25% increase in bottom end and a 15% increase in top end with their kit however i don't believe that it can breath like it should with that single 35. Also what size are the stockers, i've been told 26mm and 28mm? Would it be a big power gain or a big pain?

IMO, the stock carbs don't come close to the 2 into 1's. Believe it or not, going back down to dual 24mm stock carbs will actually give you less flow than a single 35mm. I would think it'd be a huge pain in the ass to switch out carbs everytime you want to go to the dunes. If you like the ease of jetting a single carb, I would stay with it. And unless you have a port job, you're probably not even using that 35mm to it's full potential. I would personally look into a port job, then POSSIBLY think about getting a bigger single carb..maybe a 40mm Lectron.

stock carbs won't help you anywhere over the 2-1 with your setup,I have the 2-1 and I am very happy at the dunes. stock carbs are going to be a pain in the ass.

I agree. I run the 35pwk and it was an improvement of stock carbs on top and bottom. I ride almost all dunes so if I ever went back to duals it would probably be 33 or 35's.

Sweet. thanks for all your replies. So the stock carbs are 24s?

You're right...I had a brain fart. Sorry

I too run the Paul Turner Mid Range pipes and the Trinity 1 into 2 carb set-up.

Iif I were to do it again, I'd go for some top end pipes like T5's or so, then some porting with a 40mm carb. That should rock it up nicely for both the dunes and racing.

i run the 35pwk and pro circuits. i like the combo a lot good bottom end, light switch power band, revs out pretty high. with the lake effect when we hit the dunes in the morning it can be 20 degrees warmer a couple hours later. jetting's a piece of cake.
