Are the S-1 White lightnings equipped with different heads that the Lightnings? And what, if any, are the other differences???? Thanks!! | ||

Yes, the White Lightning has the high compression heads which was identified by the heads being painted black. Also there is a number in the vin that identifies the bike as a White Lightning but I don't remember what it was. Other than the heads and graphics I don't remember there being any other differences. | ||

S1Ws had the "Thunderstorm heads" ala Thunderbolts. 101hp v 91hp S1Ws were the first production lightnings with the large fuel tank. The first few were all white, later colors were added. Correct me if I'm mistaken there may be other small diffs. (Message edited by sleez on March 04, 2005) | ||

Differences include: Cylinders Cams Intake manifold Exhaust ports Headers Seat Larger diameter frame tubing Larger tank Here's a cool review from Motorcycle Online. IMHO, the White Lightning is the best and baddest bike out of East Troy. Only needs a few aftermarket tweeks to make it beast on and off the road.  | ||

first i've ever heard of the larger frame tubing??? forgot about the cams, exh ports are part of the head! forgot about the header, didn't know the seat was any different, didn't know the intake manifold was any different! and i thought i knew my buells, i even have 2!! | ||

The seats were slightly different because the larger tank will not fit with the S1 Seat. Had no idea about the tubing and cams. What cams do the White Lightning run? (Message edited by Newfie_Buell on March 05, 2005) | ||

i thought the 98 got the aluminum swingarm as well, and how'd they get 101hp was the 98 fuel injected? i thought the x1 got the 101hp in 99.. | ||

I don't think the just white lightnings got the bigger tubing, it was all the 98's. I'm pretty sure the tube in question is the triangle that supports the front Heim joint. Our frame brace is set up to clamp the diameter of the tube on the 98, but comes with a shim tube to allow it to clamp the 96/97 lightning frame. I don't think the other tubes changed. You sure about the cams? Aren't the same lightning cams in the 98 S1 and 98 S1W? I've never heard differently. Al | ||

My bad on the cams. I was thinking of the difference between the S1/S3 and the M2. | ||

The Thunderstorm heads are the same compression as the Lightning heads, both are 10:1 but require different pistons; the Lightning heads using the same ole flat top sporty pistons; the T-Storm heads using domed T-Storm pistons. The Thunderstorm heads are higher performance, better flowing design. Larger valves I'm thinking? Why don't we all know this stuff? Cams are the same, both have the "Lightning" cams. If I hadn't pissed off Aaron, he'd chime in and set us right on the subject. | ||

Tubing stayed the same In 1999 a cross member was added much like American Sport Bike's clamp on unit Intake's have been the same on all Tube frame Buells under H-D's rule Manifold and 40mm CV carb, Except Kali model S2's Quicksilver carb. Cams of course have always been lighting cams Steel swingarm was still in efect, the aluminium swing arm wasn;t offered until 1999 which I might add was claimed to be 200% stiffer than it's predecessor. Between a Reg S1 and a S1WL Minus colors and rim options T-Storm Motor (New heads and pistons) Exhaust collector enlarged from 2 inches to 2.5 5 Gallon Manta tank Seat pan was altered to accept the new tank. and that's it. Of course when first introduced it was only available White on white on white. | ||

why'd ya go an •••• off Aaron? | ||

how come you can say •••• and i cant? | ||

oh i see pissed is ok •••• is not i get it | ||

Funny profanity filter ain't it. As to your question... It is apparently in my nature to •••• people off every now and then. I'm trying real hard to stop that though. Lessons learned and all that. | ||

The S1W's used high density race foam in the seat. As I understood it the S1's did not. The piston \ bore size was changed (stroke ratio) in the front brake master cylinder for the S1W to give it more feel over the original S1 set-up. Many who'd ridden an S1 commented on the rather sharp acting front brake. Rocket | ||

Lightning heads use 1200 Sportster valves with the basic combustion chamber shape of an 883. It's a 10 degree roof with no squish area. The Thunderstorms use larger valves, have a slightly improved exhaust port, and use a 15 degree squish area with the domed piston. The master cylinder change was due to the change of Nissin calipers over the old PM's. The PM's have massive pistons compared the Nissin calipers so a smaller master cylinder piston was needed...it wasn't to alter brake feel. That's why I can run dual Nissins with a stock '96 master cylinder. '98 and later Buells had factory braided lines...this contributed to the improved brake feel more than anything else. |
