I've gone and done it! Installed the race kit along with N8 cams and HSR42 Quick kit. After one quick ride, here's the skinny on this set up... Lost a smidge of torque below, say 3000. Cams used to turn on about 2000-2500, now I don't seem to come on the cam until around 3000. But then it's like torching off a JATO rocket, especially after 4000 and up.  Exhaust note is sweet. The exhaust blast on the left ankle scares the snot out of me every time, though. Not too loud, but loud enough. Did not experience the rev limiter!  Throttle response, while more "touchy", is certainly more responsive, no "Keihin cough"...although that really hasn't been much of a problem since I installed the Thunderslide kit. Due to the cams, the gearing range is different. You've got to keep the R's above 3K to avoid a flat spot, although I may be able to tune a lot of this out, as the HSR is an extremely tunable carb compared to the CV40. My knee bumps the CF air cleaner; not enough to present a problem, but enough to irritate me. I will either learn to live with it, or eventually ditch it for a Forcewinder. That will be next season's decision. I seem to notice a lot more "burbling" back through the exhaust now when engine braking. Not backfiring, though. Overall power gains (butt dyno only) seem impressive. Roll-ons gained RPM quicker, and the torque curve appeared to peak much quicker than before. As mentioned before, the gearing felt different due to the higher RPM range, but I'll probably get used to it fairly quickly. As Socoken mentioned after he put his N8's in, it's falling in love with my M2 all over again. Handling is unchanged, except coming out of a tight curve you have to be a little more gentle on power as the bike wants to straighten up RIGHT NOW. My M2...I think I'll keep it.  | ||

Cangrats on your born-again Buell.  Definitely a good idea to keep the revs above 3K. | ||
| Captainkirk |
Thanks, Blake! Got in a good hour ride today. I'm getting used to the change in power band (and that $#@& air cleaner) already! The difference is unreal!  | ||

Cap'n any work needed to install the N8 cams, or are they a drop in? btw -- my right knee (I"m 6'2", 35 inch inseam) hits every aircleaner available for tubers, although the forcewider intruded on my leg room a tad less than the CF Race cleaner I'm running now | ||
| Captainkirk |
Bomber; An emphatic NO!!! The only thing you need to do is check your gear-to-gear clearance and backlash (complete instructions with the cam kit.) It was easy as falling off a log. Well worth the $ and time IMHO. It also gives you the opportunity to look at your oil pump drive pinion gear (which Reepicheep has so famously addressed). Other than that, the valve train is simply R&R- same springs, push rods, lifters, etc. Complete info is available on the Andrews website (www.andrewsproducts.com) A great "bolt-in" cam. | ||

Hey Bomber! have checked into a Rizoma? My is really close in, not like Forcewinder and some of the others. | ||
| Djkaplan |
Thanks for the great product review. I definitely see some N8's in my future. | ||
| Tom_b |
How much tuning is needed to install the N8 cams on an injected motor. was thinking about it, but don't want hassles with with the fuel injection. other than race ECM it is stock. | ||
| Captainkirk |
A good question. To be honest, I swapped carbs at the same time as cams, and it runs great right out of the box. FI I'm not sure about. The stock Buell Lightning cam that you're running in your X1 is the same as the Andrews N4 grind...the difference between the two being as follows; N8 Timing: 56/28 Duration@.053:264 Max Lift: .500 N4 Timing: 52/24 Duration@.053: 256 Max Lift: .490 As you can see, not a whole lotta difference. I think it'd run OK. You could check with Andrews direct. They generally answer technical questions in a couple of days by email, or immediately on the phone if you don't mind holding. Good people to work with. | ||

Cap Thanks a million -- I appreacite the backup! Tom -- nossir, I didn't -- I wanted to stay with a know quantity, and both the force and the race hamcan are well know, and well know for producing power -- got some dunber on your Rizoma (otrher than price which was considerable, once upon a time, if memory serves)! | ||
| Tom_b |
Yeah the rizoma is pricey. I bought mine used, but still in the shrink wrap from a guy who never put it on for about 1/2 of new from a dealer. I like it. About the cams, on paper there isn't much difference, how about actual performance. On some autos the computer will "learn" and adapt to a slightly more aggressive than stock cam. Will the Buell computer do this? | ||
| Timbo |
Just another data point... I put N-8 cams in this bike, along with a HSR 42, race ECM and race air filter. It had dual plugged Lightning heads. It pulled like a freight train right up to redline (7200 rpm) and I loved it.  I bought this bike before I knew about Buells, but I think it's pretty obviuos which way I was leaning (pun intended) when it came to mods. Timbo | ||
| Captainkirk |
Update: After riding today, pulled the plugs. They both look like she's running lean (white-ish deposits on the center electrode, insulator and ground electrode). I'm running the stock HSR42-11 jets; a 25 pilot and a 160 main (according to parts book;I haven't looked yet.) My brother is running essentially the same setup in his'97 M2 and upped the pilot jet to a 30; I guess that's where I'll go next. I'll report on what happens. PS- I'm definitely getting used to the "ham can". | ||
| Tripp |
at a quick glance it looks like that sporty does'nt even have handlebars  , cool bike tho! so kirk you installed the hsr42 easy kit and seem to like it, i plan on slappin one on my cyclone this winter is it really that more responsive(worth the $?)?. | ||
| Captainkirk |
Absolutely. The CV 40 in stock form is a hacking, wheezing pig in a poke. I couldn't ride with the choke off for at least ten minutes, even on a mid-60's day. The Thunderslide kit and some jetting magic made a WORLD of difference. And the HSR is just THAT much better!. Much easier to jet and tune, as well. You could Thunderslide and jet your CV, and throw in a Yost Power Tube for, say maybe $50-100.00 MORE than I paid for my HSR on eBay...BUT WHY??? I took Aaron's advice from the KV and I'm glad I did. HOOWAH! | ||

Hi folks I'm new to the thread but here's my .02 worth. I've got a 02 Cyclone that like every Cyclone had the CV cough. Last Summer I put the Buell race kit on it and a Thunder slide kit in the carb. Ran much better but still coughed occasionally. Early this Spring I contacted a buddy that is an Engineer for H/D and races Buell tubers. Long story short, I asked for his advice to get the most ponies for the bucks. I installed Screamin' Eagle "B" cams and Screamin' Eagle Hi-perf valve springs and keepers. Freshened up the valves and had my buddy set up a CV40 for me. I can't keep the front tire down now. My low/mid torque went WAY up. My bike dyno's 91 hp and 84 ft/lbs at the rear wheel! I was surprised to hear captainkirk lost low end torque. The N8's are very nearly the same as the "B" cam set. They have a bit more overlap than the "B's". My guess would be your valve springs are a bit weak for the N8 cams. | ||
| BadS1 |
Daniel is your friends name Wes?? | ||
| Captainkirk |
I'm not complaining about the loss of torque, Maniac,just making a note of it. The EXCESS of torque at 3K and above more than make up for it! Or maybe it's the fact that it just pulls so damn hard at 3K it SEEMS like I've lost some...anyway, until I've had a chance to fiddle with the HSR some, the jury's still out (see my post re: spark plug coloring)I AM NOT COMPLAINING!!! This thing is a monster now! | ||
| Sandblast |
Welcome to the board Cyclonemaniac, thanks for posting. | ||
| Captainkirk |
Oh, yeah, Welcome, too! Where the %$#@ are my manners? | ||
| Cyclonemaniac |
Thanks for the welcome all. And yes BadS1, Wes is the one. Great rider, and heck of a resource. Just a little history on me, I bought my Cyclone slightly used in May of 03. It was bone stock. I loved the bike, but knew it had lots of potential. So really it's still a work in progress. | ||
| Tripp |
thanks for the info kirk, i guess i'm just going to wait and see if i can come up with some money for a head port/valve job, if i can't then i'm sure i'll put the couple hundred i've already been saving on the mikuni(it's part of the total package i'm going for anyway), i really hope i can get them heads done tho! | ||
| Captainkirk |
Yeah, (drool drool) just think what the Mikuni would do with a set of Nallin Stage II's hooked onto it! Seriously, though, it's just (IMHO) a flat out better performance carb, well worth the money in terms of response, tuneability, and most importantly, the ease of tuneability. | ||
| Blazin_buell |
Cy Maniac, How much did the parts and work for the cams, valve springs and keepers run you. | ||
| Captainkirk |
Update; Earlier I'd mentioned a "flat spot" around 2-3K...and now I know why. While riding yesterday I decided to try easing the choke out to see if richening up things helped or hurt...and SURPRISE!...she JUMPED forward like a greyhound after a rabbit. It only seems to affect the low end...the "dead zone", as I call it...in a VERY big way. I need to go way bigger on my pilot jet, which I shoulda known, due to the lack of coloring on the plugs and the popping thru the exhaust while downshifting (indicating a lean condition). Will rejet and report back later (weather permitting)...or, I might have to wait for spring?  | ||
| Tripp |
bah, i need a new exhaust so the mikuni will have to wait, my damb v&h slip-on crapped the bed so i'm going to have to put the carb project on hold so i can by a nice exhaust  . kirk have you had a chance to tinker with the cyclone? | ||
| Awprior |
Get the full D&D. You heard it, it's freakin awesome! | ||
| Tripp  |
lol, what do you mean i heard it? it's definitely between the d&d and the nallin force-anymore testimonials? | ||
| Captainkirk  |
Nah, the weather sucked last week and I've been gone all weekend. I will let you know, tho! | ||
| Socoken  |
"My guess would be your valve springs are a bit weak for the N8 cams." ive been bouncing mine off the 7K rev limiter and plain old thrashing the hell out of my bike with stock springs and N8s for more that 5k miles, and i think she likes it. no concerns here. maybe its my turn to take Kirks advice and get a Mik. then again, i always think about spending money on headwork, or a carb, or this or that when i read this board, but everytime i ride it, i end up telling myself "DONT change a THING." i was able to pull away from a friend on a custom with a 104" S&S motor to 120, with a passenger on back of mine. picked up the front wheel going into third (passenger might have helped). cams sure make the bike more fun. does the mik make the bike easier to wheelie? if yes, i might bite on one. thanks for posting kirk, ride safe Ken | ||
| Captainkirk |
Hey Ken! Been a while since I've seen you post! It's a "throttle response" thing. I don't think it actually makes any more ponies, but there's definitely a improvement in the "butt dyno" dept.(See Aaron's dyno chart in the KV) Sorta like ditching the "turbo lag", if you will. Once I get this thing jetted right I have little doubt it'll throttle-wheelie; it almost does now, and I KNOW it's running way lean. Are you running the T-slide on yours? PS- if you get one, do the HSR42-11 "Easy Kit" as it uses your stock cables. And if you're not happy with the results, you can always put the CV back on. I'm sure you'd have no trouble dumping the HSR on this site! | ||

| Tripp |
unfortunately i really need a new exhaust- joe why the new clutch, the old one sh*t the bed or you were looking for better performance? | ||
| Cyclonemaniac |
Hey Blazin, sorry for the long gap on my reply. Been way too busy lately. I did all of the wrench work, so other than spending $45 on a freshen up on the valves, I had no labor expense. I caught my parts at 15% off from my local dealer. As memory serves, I think I spent about$350 on parts. That was cams, springs, keepers, gaskets etc. Definately the best money I've spent on it. You can check my profile an earlier posts on this thread to check out everything I've done to it. Got a few more tricks up my sleeve though. Will have to pop the heads and jugs to do some machine work on the pistons and combustion chamber. Also planning on fabbing up an aluminum oil tank. | ||
| Bomber  |
Maniac -- hmmmmmm---- let us know how yout oil tank fabbing goes -- you give as boy idears! |
