I've done a search on this before, and I didn't get the info I was looking for. Here's my question: if I get the low profile Road King replacement lexan, will it fit in the mounting hardware that is affixed to the SERK's so called wind deflector? I know the deflector lexan has more holes, and the two vertically placed middle holes that are on the RK shield don't appear to be on the wind deflector mounting hardware.

Has anyone done this, or has everyone either gone with a Clear View or bought the entire Road King windshield assembly?

Thanks!

Yes, before I left the dealer with this '08 SERK I made the purchase of a standard Harley Davidson Road King Windshield and installed it. Yes, it is detachable and has the same mounting configuration that the small dark-tinted WS that is attached to the SERK when delivered. Part numbers are included in a previous post.

Also, RHTD's on the 110 is a serious mistake so be sure to keep the stock crossover system for the bike. The rear cylinder will heat because the rear header is a restriction with Rinehart. There is something to be said about equal length headers too and Rinehart TD's are far from equal. And once you change the map in the ECM with something some tuner thinks is correct, you cannot undo it because there are no stock maps. You may benefit by talking to some tuners in your area (that have no axe to grind) for their professional opinion of true duals and which ones would be best suited to the 110. Try some slip-ons if you are inerested in loud exhaust.

But, there is all sorts of good advice here to keep you thinking. As the saying goes, everyone that throws a leg across a Harley Davidson immediately becomes an engine expert and can tell you from '06 to '08 what you need for your brand new motorcycle...

If your question is will the 5 hole replacement shield only fit a serk wind deflector frame , NO, it has different mounting holes. You can buy the whole windshield frame and all for a regular roadking and it will mount on the SERK bike. A guy on ebay sells replacemrnt windshields in all heights and tints to fit the serk windshield frame and his prices are better than hd's. HD only offers one in 11" and 14" both dark tint.

Here is his link, he told me he would make any size wanted just send him a email thru ask vendor a question .

Staying on topic for a moment...the 7 hole bolt pattern for the mounting hardware on the SERK is not the same as the standard 5 hole, so the shields are not interchangable, though you can purchase the 5 hole hardware and put the standard type shields from HD (or aftermarket) on the bike.

Since the quote above takes this thread off topic, particularly the bolded section....I would like an explanation on how a RH TD rear header pipe causes a restriction in the exhaust gas flow out of the rear cylinder, and how that header would differ from the front to cause the restriction. There are literally thousands and thousands of RH TD's on bikes out there, and I have NEVER heard anyone say it possible for the rear header pipe to cause a restriction. While it is true that RH TD pipes MAY cause some loss of low end TQ, it is made up in the mid to upper ranges, along with an increase in total HP numbers. In fact, TD's of almost any kind will HELP pull heat out of the poorly designed SE heads, as each cylinder then has it's own exhaust flow, can be tuned independently, etc. If one is after maxium TQ, 2 into 1 pipes are the best solution. D&D Fatcats is a good choice, and a ghost pipe is available to maintain the dual muffler looks. With regards to length of header pipes being critical on a V Twin engine...the difference is insignificant...the only pipe I'm aware of which takes header length into account is Bassanni, with the loop design taking the place of the crossover pipe on the right side of the bike. It is a good marketing tool to promote equal length headers, but in reality it makes so little difference, it can barely be measured. Now if we're talking a V-8 engine, that's a different matter, and even then it depends on cam choice.

There are only a couple of tuning devices which change the ECM programming permanently...one is the SERT, the other is Direct Link. ECM controllers like the Powercommander PCIII (not yet available for the 08 models...projected release date is sometime in November), so not change the ECM, but only serve to override. You absolutely can get a stock program in your ECM, but it would need to be reinitialized via HD with their Digital Tech.

Sorry for taking this off topic, but the statement above concerning restrictions call for an explanation and source of info.

Hi there blueboy! You can do your own research, can't you! There have been discussions about the restriction on this and other forums as well. This is a case where the engine must be individually tuned for unequal cylinder charastics due to unequal exhaust pressures on otherwise equal cylinders. The tite bend in the Rinehart rear header is a problem - but they look good, and that's why they sell so well. Equal chamber volumes, equal valve events, equal piston weights and etc, why use unequal header pipes if we are talking about performance? If sound is the main concern, then fine, Rinehart systems sound good but there is too much low end performance loss. Now if you are thinking about an engine and performance, you will agree. Mid range power is fine but a V twin needs all the help it can get getting off the starting line - that's where a Harley will win, not high speed or mid range. So why sacrifice it?

Harley will NOT provide the stock map for your ECM. There are no standard maps for the entire country due to elevation and the type of fuel available locally so they are individually dynoed at the factory and mapped for their destination.

The rear cylinder of a HD motorcycle does not have the same A/F needs as the front cylinder because of differences in operating temps...front gets more air, stays cooler...rear gets less air, runs hotter. The 90 degree, radiused bend in a RH rear pipe does NOT cause a restriction worse than the stock crossover system. Have you seen aBasanni rear header pipe...if anything was going to cause a restriction, that would, and it does not. Are RH's the "ideal" performance pipe? No. There is always some trade off in choosing a pipe, regardless of brand/type. TQ does play an important role in getting a mass moving, but HP is what wins races. There are several variables which come into play making HP/TQ other than just peak numbers. More important ishow quickly does the motor rev, how well do the heads flow, and what the exhaust velocity is, which helps determine all of the above, along with proper cam lift/duration, Throttle body size, etc. Too many details for this discussion, but I can take a motor with proper head design, well matched cams, proper compression, etc and beat a larger motor, with higher peak numbers, with less efficient head/cam/compression profile, simply because one motor will rev much faster. I have a vrod that can prove that point day in and day out. Less HP, WAY less TQ than a big V. Two different motors, but TQ is not all that matters in an engine design. It FEELS good though. Dyno numbers do not mean much, other than as an indicator of total output. I'll take a dyno run that shows elapsed time to GET TO peak numbers, as that shows me more about total performance. Tell you what...show me a dyno sheet...same bike, same day, same conditions, same tuner...with stock headers and high flow mufflers, then one with RH TD's and their mufflers, tuned again, and prove to me that the stock crossovers work better.

Actually, I don't really care much about any of the things mentioned above...all I really care about is whether the bike is running well, provides the power I need to put a smile on my face, and is reliable. I don't drag race my bagger, so looks, sound, and overall satisfaction are more important than who can turn a 1/4 mile the fastest.

With the logic you are using, if I bought a HD EFI bike in Denver, are you telling me it would not run right at sea level on the coast of Alabama? That, my friend, is just simply not true. The ECM is able to compensate for changes in altitude, RH, engine temp, air temp, etc., thank goodness. If you do not beleive this, ride your bike to the top of Pike's Peak and see if it doesn't run just fine. If you had a carb'd bike, it would not.&nbs

And the point to all this relating to the winshield question is what??? RH true duals make your windsheild fog up if used on a SE. You guys are waisting all this good tech talk, most will never read a windshield thread trying to learn more about their exhaust pipes.

There is some correction that the ECM does within the RPM range that it is closed loop but yes, there are individual maps for localities - maybe too broad to be considered custom maps but there are no standard maps. HD is not in the map business anyhow. The fine line between running good and performance is where many people spend lots of money. You make a choice and follow through, that's all you can do - if it's wrong , do it over. There are as many opinions and ways to approach an engine as there are Harley owners.There is no limit, just the knowledge and resources to get it done. I've been at this business for many years and have built a few Harley engines in my time. I still build engines, now only in minature - every piece. But I enjoy staying active with maybe presenting an opinion that may spark some thinking because lots of guys don't have the ability to do this their own work nor make good decisions about what they desire to achieve.

You should let go of the sacrcastic nature that you possess. You can't be so unhappy that you must be so rude. If so, I'm sorry for you. I let you make me angry on another post but I see you now, it will not work again. I'm thinking that you are one of those liberal folks who don't believe in freedom of speech because you have shown that you don't respect anyone elses opinion! It must be horrible to go through the day with such a sour taste in your mouth! Clean up your act, like I said; you would seem to have some class somewhere....

You're right Gunrunner. Bluesboy is having problems....

Also: this has been proven not to be true: The rear cylinder of a HD motorcycle does not have the same A/F needs as the front cylinder because of differences in operating temps...front gets more air, stays cooler...rear gets less air, runs hotter. Aircraft engines would melt at the back of the engine if this were true. There is no slipstream with a Harley at highway speed so the rear cylinder does not receive less air and the temperature differential of the front cylinder air is so slight that the rear cylinder cools just as well. That is an old arguement and has been disproven several times on various race tracks as early as the 1950's with the knuckel head. Good presentation there bluesboy, but no cigar!

And who is the sarcastic one? Please, no name calling. I am merely presenting facts as I know them to be true.

There are lot's of ECM's on pre 07 HD's that do not run in "closed loop" at all, yet they continue to function just fine wherever they are ridden, all over the country. I honestly do not think HD puts a different map in the EMC for each destination...I do not want folks thinking they are going to have drivability issues because they bought a bike in Miami and are scared to drive it to the Rockies. It will adapt.


And Gunrunner, you are absolutely correct...this has no place on a windshield thread. My apology.

Earlier though, I did throw out some good options for aftermarket windshields, like Clearview. Check them out...great people to deal with, and an excellent product. Takes a while to get one though.
