Lock up clutch... Drag only?

I'm new here. I've owned the same banshee since I was 14 years old and it's gone through several changes motor and appearance wise. The most recent change is I sold my Stallworth race ported cylinders and head that was set up 4 mill and my very kind girlfriend bought me a 421 Cub kit from Titan Racing down in Mississippi. We've been pricing them for over a year now and these guys are by far the best priced you will find around. Anyways, I'm putting the motor together as anybody reads this. I know I'll need to upgrade my clutch, carbs, and exhaust. I found a great deal from a guy that was selling a stock motor bike that had the Shearer in frames and traded my old T5's plus some cash. Clutch wise, I've been really considering a lock up from Direct Drive. I've been seeing this set up for the last couple years down at Little Sahara. I've never ridden one with this set up. I've always been curious, is this set up alright for aggressive trail riding and hill shooting and all other crazy fun stuff? I've got the Hinson basket, pressure plate, and inner hub with the Barrenet "Sh*t Digger". My factory cylinder 4mill set up would torch this clutch set up in no time. I haven't been impressed with these clutches at all! Any better way to go? Also, my most local shop (NMotion) says to stay away from the lock up and go with their 10 disk set up. Very pricey compared to the lock up. Anybody run that? I've seen very very few of em at the dunes. Also, what carbs are gonna be my best set up? I'm running some really really old TM Mikunis 28 mm. They will have to due for the time being, same goes for the clutch due to finances. Is my jetting gonna be way way off? I figure it will have to be changed due to larger displacement and port design. Sorry for so long of a note everybody! Just have a lot of questions rattling around in my head. Any suggestions very welcome! Thanks!

You could do FZR1000 clutch plates and barnett steels (pretty sure that's what Jeff's kit is or something similar) and 6 heavy duty springs. That should hold the power you're going to make.

 

The lockup is great though, no problems duning or general play riding. You can get different sized weights or even takes the weights off so it acts more like a normal clutch at lower rpms and doesn't "lock up" until higher rpms.

so what your saying is that u can let out the clutch the same way with the lock up as a normal clutch.

I've never run a bike with the cub set up. My factory cylinders made MAD power. Tim at Titan told me that I'll notice a night and day difference. So, you think without a lock up and the clutch fibers that you recommend it'll be reliable. Also, the ports are cleaned up and matched to the case. I'm running a Noss head with 17 or 16 cc domes.

if you run a lockup, you will need a duneable override. motors with lockups that dont have overrides will not shift under power. you will have to back way off the power to get it to shift.

 

personally i would just call FAST 785-364-5325 and get his clutch. its a great clutch and i think itll be fine for your application. just make sure all your other clutch parts are in good shape.

Cool, glad I got on here before I started dishing money out on something that won't work for me. Carb wise like a PWK 35 would be best? I wanna be able to ride the trails and kick some ass on the drag strip. I still have a stock length swinger on it too. I think its fun! Old motor I'd pull 6th gear wheelies on the blacktop! For the guy that suggested the FRZ1000 fibers, what year do I order if it makes a difference?

 

So, the lock up is an absolute NO with out an override? Too bad, they look really really cool! LOL!!

Just go to F.A.S.T. or call that number that LOCO gave you and order the F.A.S.T. Clutch i think it uses the frz1000 fibers. Stock length on a cub. Better get a wheelie bar!!

Thanks! I'll call 'em or email this week. How you like those Lectrons? What's tuning like on em?

Haven't Got to run em' yet. My bikes not completely together right now (Getting there though) A local guy around Tulsa runs them and he said they are way easier to tune than kehien and mikunis so that why i went with them.

lectrons are junk in my opinion. cheaply made for one reason, to dump a ton of fuel into carbs. the whole metering rod deal is a joke. there are a million of them but you have to find the right one. they come in a ton of different lengths and thicknesses.

 

i would stick with keihins. they are very simple to tune and are built well.

I to have herd that. Lectrons are only good for WOT drag passes.

Besides, the carbs and clutch... Any other necessary mods recommended for my transition? A port job is in store but that's down the road after a job promo.

 

 

I'll still be running the stock radiator. I never once had any cooling issues with it as a 350 and a 4mill. I pick up my Shearers tomorrow and part ways with the Toomey's. Can't wait!! Only need the studs for the head now! If it wasn't 15 degrees outside, I'd be on my way to Little Sahara the day after I get it running. Thanks for puttin up with my ongoing and relentless questioning guys!!! :beer:
