    You could always put an auto clutch in if your getting too old to shift, like Tapio did:oldsmile:

    Haha! Maybe so, I don't expect you too understand Ker, your riding style is definitly different than mine, when I rode your bike out of respect I kept the rpm's very low, when I ride my bike I do actually get on it every now and then, the bike will probably have a top speed of at least 140 mph, I myself have taken it up to 130 mph or so, speedo was pinned so I am just guessing, anyway I really do not need to go that fast ever, so anything over 80 mph is a waste in my opinion, so why not gear it down to take advantange of the horsepower at lower speeds, kinda like a drag car in a sence, ya follow me buddy? Hehe!

    Then ya better start using torque values and loctite so your not loosing bolts off the bike, if your looking for speed, get a crotch rocket. If your looking for power drop down a gear, keep it above 4000k rpm
    Kinda like buying a Honda Civic to do 120mph, buy something that will do it easy, like a Hellcat:p Easily achieves set goal:whoop::old2:

    Remember, I bought the bike used! That means someone else worked on it hoser! The bolts that fell out prolly were due to someone that did not use locktight on the bolts, and yes, I did use locktight on everything I work on, eventually that will be all the bolts on the bike! Again, I did not have the luxury of buying my bike new, your bike has only had one mechanic, YOU!!!! Thanks for you advise though, it is greatly appreciated bro! :whoop: :old2:

    Opinions are like a$$holes, everyone has one, and that's why you posted this thread, but reading back I do believe others have said why? So some a$$holes might be some what similar.:oldsmile:

    Maybe I should've use a Vette or Camaro instead Chubs, I mean Cdoggy.:oldlaugh:

    If you know where you can buy different belts and drive gears, I would think he would be your go to guy and he will have all your answers.:eek:

    John,

    No one makes a different pulley for a late model BD that I know of so I made one myself. Stock is 34T so I started with a 32 tooth on my bagger and finally ended up with a 31. To do it you have to take a stock harley type pulley and do some machine work to it. It is by far one of the best mods that can be done to a BD. On my bagger with the 31T it runs about 3,000 rpm at 72mph. Most people would be fine with the 32T as belt length and clearance issues can come up with the 31T. If you are interested and feel comfortable with changing the pulley yourself I can probably get one made up for you for a few $$.

    Send me a pm if you want to chat more. :oldthumbsup:

    Mike

    What gear you in at 70 & 3k?

    I was just out yesterday and thinking about this cause right now at 70 I'm 3.5k in 4th and like 2500 in 5th. I'd like to be at 3k at 68-70 rather than in between 4th and 5th cause I end up having to shift a lot.

    If I lived up north the gearing on the stock BD would be fine as most speed limits are 55-65 but considering we have a lot of two lane routes I ride with speed limits of 60-70 here it makes some sense.

    I dont care about torque of speed just want to not be inbetween gears between 68-72mph. As I find myself switching to 5th and end up going 75 instead of 65-68. I might even do fine with one tooth, just 33T. It's pretty close.

    You don’t want a hellkitten, they are slow. My old beater daily driver truck beats them all the time. Of course, the Dart LSNext2 block and the 98mm turbo help a lot. 1638hp on e85, with a different turbo on methanol it showed over 2500 before traction issues became a problem on the dyno. And I still haven’t wasted as much money as a hellkitten costs used. A/c blows cold and it gets 23mpg.

    I make too much money grudge racing the truck to throw pics around. Plus, it’s a sleeper. Just looks like any other 88-98 rcsb Chevy.

    I'm curious about this and have been for years. I'm between 5th and 6th on the highway. Most everyone does 80mph around here and I'm a bit high in 5th but then lugging it in 6th. Any idea on price??

    Lol, under the hood looks as crappy as I could make it. I painted the billet block black, then after installing it, I painted it orange with lots of overspray. Turbo is mounted under the passenger floorboard, all steel is rusty looking. I spent days with a dremel and epoxy trying to make the heads look stock, adding in stock casting marks and numbers. Lol, people taking a look under my hood is what gets me big money races. I also try to dress and act the part of a dumb hick. You gotta play the game right to survive in grudge racing.

    Let me check with my machinist, but Im thinking around $350. about half in the pulley and half in machining. Baker pulleys cost more and machining them is harder also. I have used cheap harley pulley and a baker pulley on mine. Not sure that it makes a difference either way as I don't put a ton of miles on my bike. I have put around 6,000 miles on it since the pulley change.

    Sometimes they are at outlaw tracks. A lot of times events are held at old airstrips that have been closed. No prep is getting so popular that more are being held off of normal tracks. A lot of times they will rent a street in a gated warehouse complex. Then some small towns will close a street for racing once or twice a year. Alvarado has been doing an annual event. They claim it keeps the street racing down. And they look the other way when people start throwing money around. Most are pretty nice events, no drunks or druggies, no fights except the goofy bs when drivers are trying to build up their race. This isn’t street racing, at least not the kind on public roads with traffic. It’s actual events with emt’s on hand, fire crew on hand and liability waivers all around.
