Check it out guys, I was removing my air box's back plate on my Y2K M2,to investigate a possible rocker box leak, when after removing the front head breather fitting, and removing the back plate itself, I saw what looked like some stray RTV sealent in the forward hole(orange in color, thats probably why I noticed it). When I got done trying to take it out with every little tool I own, you would not believe what I found!!!!!! It was the end of a red plastic bristled brush, probably used to clean out the passageways, about the size of a mans pinky finger-nail!!! I was totally flabergasted!! What should I do!! The dealer said he could look at it and reinstall everything for me, but I can do that. I asked him if I should call Buell, but said he was not sure what that would accomplish, if anything. He gave me the number to Harley Davidson customer service, but what would they tell me, "Take it to dealer to look at it and put it back together."? I am wondering myself, what else could have been left in there during the assembly process too!!!!! The motor has 2500 miles on it now, and nothing has ever been worked on inside the motor since I had it. I does not seem to make any more noise than any of my buddies bikes do, and it just plain bothers me!!!!! Please help, ANYBODY!! A number I could call or someone specific I should talk to!!??!!  Thanks Guys in advance, you have always been a great help with everything! Bruce Disturbed but not down...............yet. | ||

Ray: What are the chances they dislodged two pieces of FOD in your engine. Not likely. If it were me I'd let it go. You could always do a boresight of the internals if you are really worried though. Plus, any failure due to factory FOD would hopefully be covered by the company. Blake | ||

I have heard about those fans for the Buell S3. Has anyone have a pic of one they can e-mail me? Is it a eye sore? Is it worth it? I asked a similiar question regarding a oil cooler. I live in Yuma, AZ and the summers can reach 115 during the day and I still ride. I'm worried about my engine overheating. Any pics, opinions, or info on the fan and oil coolers is welcomed. Someone I spoke with said that Eric Buell has stated that the engine doesn't need a oil cooler, and that any given time there is very little oil in the engine. I really don't know that much so I hope you guys can enlighten me. Also any Buellers here AZ. Would love to get a list of riding buddies. jhbushmasta@aol.com | ||

Jh Just had the fan put on my S3 the other day. With the lowers on you can not see it. without them it might not look that great. As I understand it, the fan was designed to keep the fuel cool prior to combustion in the Japanese models. Apparently Japan has highly combustable fuel that would get too hot in the fuel line. I will let you know if it cools the cylinders any. RobS | ||

Does anyone know if there is a website where I can get information regarding the removal and replacement of the rocker box gaskets on the rear cylinder on a 2000 X1? I have an oil leak and would like to try and do this myself. Any information would be great! Thanks, Vince | ||

Can larger valves be installed into 883 heads? My dad is doing a 1200 upgrade to his Sporty and I talked him into using T-storm heads. We now have a set of 883 heads just sitting around. I thought I might play around with them and maybe polish the ports, install short valve guides, recontour the guide shrouds, polish the CC, and MAYBE install slightly bigger valves. Would you believe that there are some people reuse their 883 heads on 1200 conversions? I know I won't get rich off the heads, but anything is more than I have now. | ||
| Jmartz |
FB: It can be done but it is in my opinion cost-ineffective. Some racers like Tilley claim that because they have smaller ports when porting these a shallower curve can be achieved resulting in an extra bit of power. Not worth it considering the machine shop costs. You will never get it done for the cost of a set of T-heads that you can seat blend yourself with a dremel. Don't forget to tell your dad that the bottom end needs to be rebalanced if he wants smoothness, longevity and all the realizable power from the conversion. Its a bitch to transform an 883 into a 1200 properly. jose | ||
| Fastback69 |
I've told him about rebalancing the recip. parts. I thought I might try to sell the heads to someone looking for a cheaper way to convert their 883 over. Besides, I like to tinker. | ||
| Blake |
Just in case ya mighta forgot... remember the T-storm pistons too. | ||
| Fastback69 |
Got 'em. His original plan called for SE heads, 1200 pistons, SE jugs, and SE I or Andrews N4 cams. I talked him into the T-storm heads (which are cheaper)w/ pistons, Lightning cams (which come with the pinion in a matched set), and boring his 883 jugs ($100). I saved him a little money. Why are the SE heads more expensive than the T-storm? | ||
| Jmartz |
N4 cams are a bad choice. SEII's is the way to go. These are the same as an N6 with more lift. They come with the spring set and Ti collars. Jose | ||

I was getting ready to remove my cam cover and have it cut down. After draining the oil and breaking loose the bolts...I thought now would be a good time to check the manual. Well, not having one for the Buell, I turned to my 93 sporty manual. It says to do all kinds of stuff...like remove the pushrods and valve tappets, and check cam gear end play before removing the cover. My question is this...since I dont plan to remove the cams, do I have to do all that? I just want to take the thing off and cut it so it looks good. Anyone here done this and can help me? Thanks...and yes...I am ordering a manual for the buell. | ||

Hey, that's one of the things I asked about at Brian's HD/Buell tech night last Friday. Jamie actually volunteered that he knew of a trick that would allow removal of the cover without having to dissassemble practically the entire valve train per the service manual. The trick has gotta be the crank position Aaron mentioned. See Rob. No notes, and I darn near forgot something impotent! | ||

Paison, I did mine on the bike...took a while, but the results were worth it. Did the whole job with a pneumatic die grinder, a zizz wheel, a carbide grinding bit, and some polishing wheels. See it at S1W photos It was a bit of a pain in the butt, but it would have been more work to take the rocker boxes off to do it. Al | ||
| Paisan |
Al....did you do yours with the cover on the bike? or did you just leave the rocker boxes on and jimmy the cover back on after you were done? | ||
| Al_Lighton |
Paison, On the bike. The only screw I took out was the one to mount the catch can. The carbide bits can chunk away serious aluminum fast. That can be negative to, keep it under control. One touch anywhere you don't want it and you've got a divit. If you do it this way, and use a zizz wheel, use the thinnest one you can find and you'll cut lots faster. Al | ||

A new set of Thunderstorm heads and pistons have arrived for my 97M2. I hear a lot about how much of an improvement they are over previous heads mainly because of improved porting and that all important squish band. On closer inspection I found that the pistons have around 10 degrees on the squish ledge but the heads have an angle of about 15 degrees on there corresponding squish area. To my way of thinking, this does not make good squish. In fact I would go as far as to say it does not work at all unless both these areas are at the same angle and running around .050" to 0.060" squish at operating temperature. (for alloy barrels that is) What do you think? Paul | ||

JPh: You are right about the top piston geometry but the combo will still make a bit more power and torque. You would have been better served by using Nallin's hurricane pistons a they increase the compression to 10.5 while the stock ones, although claiming 10 are less (closer to 9). You will notice better off the line performance and not much difference on the top. Bite the bullet and send the heads out to port and return the pistons (or just toss'em). With this mod you will get 95 HP with a 4 degree retard on the pickup plate. Assemble what you have and you'll be lucky to get 80 HP. Jose | ||

Thanks for the info Jose. Although I'm not totally convinced that the Thunderstorm piston is a complete loss. They are nicely made and the weights are within one gram of each other. A good start. From what I can see the 10 degree ledge on these pistons could be machined to 15 degrees. This would reduce the top ring land by about 0.040". (Plenty of meat in this area) Machine the barrels by the same amount, a bit of attention to gaskets and I should end up with good squish and compression numbers. That's the theory, will see how it works. Paul | ||
| Jmartz |
JP: I did something similar to that on a set of Lightning jugs and heads and the bike produced 83.4 HP. What you intend to do which is to adjust the squish band and increse the compression will definitely improve the final results of the conversion. If you are able to get the compression high enough the T-storm piston should outperform the hurricanes because of a shallower dome for better flame travel. The benefits of the hurricanes is that they do not require machinework. What is it at these days $125/hr. with a 7 day minumum? | ||

A while back, a gentleman made a post about putting Blast rocker covers on a Buell Evo twin. I've looked but cant't find the post. Do you have photo's yet? What advantage do the Blast parts have over the 2-piece covers, other that 1 less gasket? | ||
| Johnsachs |
Fastback, Blast covers are: 2 piece have better /larger breathers lite weight inexpensive much better deal. | ||
| Fastback69 |
Do the breathers exit differently? I looked at a Blast at the dealer, but don't remember seeing (or couldn't see) the breather outlet. Do you have any pics, yet? | ||

Here are few pictures of the cam cover trimming I did today.   Notice the outside dowel area has been left intact.  I also reinsterted the plug in the underside. It has to be redrilled. I also lock-tited and staked it. I always said, "If it's worth doing, it's worth over-doing." bighairyralph | ||
| Paisan |
ralph... that cover looks great! When you took it off, did you remove the rocker boxes? Or did you just take off the timing stuff and then the cover? I am in the middle of this and I need some tips. I hear arguments on both sides. Also, did you do the cutting yourself? What did you use? Also, when you put it back on, what is the tightening sequence and torque numbers? Details, details. | ||
| Bluzm2 |
Paisan, BHR cheated! He has his whole motor apart and out of the frame. Serious mods in progress. Check out some his previous posts, it's gonna be a monster! BluzM2 | ||
| Ralph |
You guys got it all wrong. I tore my motor out so I could trim the cam cover. Never occured to me to cut it on the bike  While I was at it I played around with a couple other things. Now it's lookin' some thing like this  Paisan, I used a band saw, belt grinder and red scotch brite to finish. I would not take the cam cover off without taking the rockers loose, personally. Torque numbers are all in the manual. bighairyralph |
