: Exup valve
Truck 03-21-2004, 05:01 PM Ive noticed when standing behind my brothers R1 or my buddys RC51 the exaust hits you in the chest, but on my 954 it seems real weak comming out of my Jardeen can. There isnt any sighns that its not running right exept where people on here tells me that 2nd and third gear wheelies should be no problem," when they are for me". Yesterday I did a first gear wheelie and It hit a point right before I was getting ready to go into second and It just surged on me and next thing I know Im looking at the sky, l sware I pulled a biaggi wheelie, it was that bad I almost wrecked.
Anyway do you guys think that I need a exup valve adjust? Thanks :wink:
cbrjimmy1KRR 03-21-2004, 10:13 PM the 954 has surges around 3 and 7 grand....with the HTEV valves. be damn careful about doing 1st gear wheelies.....it's very touchy in 1st and will put you on your ass in a hurry. try getting it up around 7 grand in 2nd then open her up....either blip the throttle or learn to clutch it. it's smooth and very strong from 7 grand on up, or go with a full system and it's smooth everywhere. i don't miss those surges one bit!!!!
Friction954 03-22-2004, 12:31 PM I raced an old GTO the other day, with my girlfriend on the back of the 54, and had one of those first gear surges... had the wheel up at about 10-11 oclock for 3 secs, then set it down and kicked the shit out of the goat!
:wink:
Truck 03-22-2004, 12:36 PM For some reason I have to get the thing at about 9 or 10 grand and blip the throttle to get the fromt up. Ive tried clutchin it but it doesnt seem to want to do it that way, Im probably just doin it wrong. Most of the time if I roll on the throttle real smooth it comes up smooth and I just quickshift into second and keep riding it on out but the other day I held it a little longer and it almost cost me. I can get 2nd to come up if I really get the RPM's up to about 9 grand but I can forget 7 grand It just wont do it. Its funny at that point im doing about 100 or so. Well this is why im thinking the HTEV valve because when I first start the thing it has almost no exaust pressure comming from the can and my brothers R1 has loads of pressure comming from the can.
Well anyway thanks I am considering spending for a full exaust just havent decided to go that far yet. :wink:
gntbldr 03-23-2004, 01:52 AM hey Truck... you could go as far as to riggin up the valve on the pipe to an open status and then tucking the flapper in the air box under the inlet ducts to get what you want...
I'd be very interested to hear of the results!
with the valve on the pipe just disconnect and remove the cables at the base(and above) then rigg the htev open.
in theory it should work safely since you have put on a less restrictive silencer. Heck... you may just get a bit more out of her too! in the low to mid to high mid rpms...)
Truck 03-23-2004, 09:33 AM My brother did that on his r1 and it killed the mid range right out of her. I am probably going to give it a try just to see. I am checking it know to see if it is set properly. Ill keep you posted to what it does cause im cureous too. 8)
4passin 03-29-2004, 08:46 PM truck I too have never been able to do throttle wheelies in 2nd or 3rd- I hardly consider myself an expert on the subject though.
for 2nd gear clutch wheelies, those are like butter. The key is to snap the clutch out, not let it out with your hand. IT needs to engage as fast as possible and then it rises up.
Start with small rpm dumps in 2nd gear and work your way up. It took me a while before I could redline it and feel good. I think my sweet spot is about 30-40mph in second, then squeeze clutch, full throttle, snap, and it comes up. Try to release before the rev limiter kicks in, casue if you catch it on a limit, somtimes it acts funny. You can sit a little back to help it come up, but no need to be on the back seat.
It became second nature, I used to run them out to red line which was in the 109-111mph area.
I dumped hard at about 60mph, and now I don't do them anymore. Bike started to flounder and the back tire broke loose while I was at 11 oclock.
If you want email me and I can send you the dump video...it's a few MB's shadytype@yahoo.com
GEAR UP.
Truck 03-30-2004, 11:54 AM Yea im probably not letting out quick enough. Thanks for the info, I was begining to think there was something wrong with my bike. One things for sure going up an incline now thats a different story, if I snap then it will come up. Ill email you my adress in a minute, I want to see the clip. You should post it on here for everyone to take a look at.
My surge the other day put me straigh up at 12 oclock at 85 mph it then started that sway that puts your ass on the deck, I rolled off as fast as I could and got the front down and barely salvaged it. Then right after that I ran the thing to about 85 in second jumed the thing in the air and rode the longest wheelie ive done to date.
Im gonna work on that and see what I can do with it. A freind of mine showed me the quick shift in a way that is somewhat smooth so for going from 1st to 2nd its not that harsh. I think the only reason that i want to get it up in 2nd is so i dont have to slow down on the interstate to bring it up. Any more info is appreciated :wink:
I did do the first standing wheelie in first the other day, my leg wasnt killing me enough for me to try it. I did it real smooth and rode it through the rev limiter in first. This is the other reason I want to get second up so I dont kill myself in first. :!: :wink:
gntbldr 03-30-2004, 05:27 PM on the freeway, at 80 down to 3rd with a rev,REV-POP it'd come and go till the front slowly came down.
it wouldn't work at 75 it wouldn't work at 85. Only at 80
second was like 65.
fun shit.
wow. I remember that vid 4passin.... not fun shit. vid showed the things that can happen out of no where that's for sure.
Truck 03-30-2004, 06:50 PM I went out this afternoon and began to practice with 2nd and I learned a few things. One was that I was trying to come up at the wrong rpm. I realized that in second more isnt better. Someone and I forget who told me (I think it was wheelie) that 7 grand was the sweet spot and he was right. Im a big guy so I have to do a throttle smack and it comes up pretty good right to the pivit point. I did get 3rd to come off the ground but not high enough to hold it there. I will say I rode the longest wheelie today ive ever done about 400 yards or so. You really cant tell when youre doing 108mpg when you come down. Now ive got to learn to lean back to make myself a counter balance for the bike. I realized what was happening, when you smack it at 7 grand as it starts to come up then the exup valve opens wide at 8 grand and gives you the extra boost to come on up. Thats why it doesnt work anywhere else. Now Im sure there is plenty of people here that can get it to come up at other rpms and maybe with a little practice I will too. I will say that I tried to realease the clutch several times but the tire only came off the ground just a little and back down. I like not abusing the clutch a little better. I did rev it out and release and pop the clutch to get it to do that. Any way wheelied by a deputy sheriff about 200 yards or so and called it a day cause it was getting cold.
Any more ideas im listening :idea: :wink:
gnt youre right there is a sweet spot and you have to hit it. Ill get there im already doing it.

Ive got a few dvds that have some real bad wrecks that you probably have seen and Ive realized that all it takes is a couple of sways on the back tire and youre body slamed at 80 or so. I almost did that myself the other day thats why Im trying to get this figured out. I got it up really well in 2nd several times this afternoon and im gonna try to do the third next ride. Now can you do a throttle drop or do you have to clutch it to get it up at 80 in third, and if you have to clutch it do you have to rev the shit out of it :!: :idea: :wink:
fukinnuts 03-30-2004, 07:12 PM Try loading up the suspension by giving her a bounce. I do it in second, third, and fourth gear. You got to have the rpm's at around 7k, then back off the throttle, bounce, and as you bounce up whack open the throttle. It comes up smooth sitting or standing and you don't use the clutch.
4passin 03-30-2004, 08:13 PM GNT- I thought you might remember. Not nearly as rashed as you were, but I wasn't going as fast, and I bounced a lot more before I slid.... . It was about the same time someone else wrecked it on 954.com too.
Truck, it came down so fast I went over the front....tossed me like a rag doll.... Came down crossed up.
Basically I brought it to the balance point, and the bike listed hard left, then wobbled I goosed the throttle to bring it back up straight, but the tire was already on edge, and it broke loose. then the front came down crossed up, threw me over the bars....
clean out your email and I will send it to you.
you guys are nuts doing 3rd gear wheelies.... I bow before you. coming down as 110mph was enough for me....
4passin 03-30-2004, 08:18 PM oh an leaning back is key- it smooths out the wheelie
Truck 03-30-2004, 08:24 PM Ive about screwed up a couple of times, but basicially I try to pick a good line and going straight on smooth road before trying anything. Its my feeling that rough road isnt the place to wheelie. A good bump or something can sent you adrift quickly. I think I will work on the 2nd gear ones and get good at them before I go for the 3rd gear ones. :wink:

Got youre vid, man that sucked. Thats just basicially what can go wrong, did you get hurt on that one it looked to me that you went in front of the bike and it just slid all over you. :!: :(
