    performance intake mod

    finally starting the intake modification that will need a bit of refining to work.

    i bought an intake filter with a 3 inch diameter and it actually seems like it could work very well with a little bit of tweaking but it has to be done right so there isnt any air leaks going on, im curious if theres anything i should know about this beforehand and also id like to reach out to the people who i known have done it before and made it work. the one person i know i dont remember his name but he does have an early 90s gsxr track bike and is in ireland if i remember correctly.

    hoping this can be done successfully and prove great results.

    Have you spoken to Grimly about doing this? It seems that it might be a lot of work for minimal payoff and possibly less than perfect results.

      I'm in no position to offer any advice as my experience is particular to a specific application.
      However, there is one of the 1100s that has a large common filter poking out the back, and pictures of that have been up. The factory filter was replaced with a K&N cone or cylinder.
      From day one though, the airflow from the filter to the carbs was designed by the factory, and none of that was changed.

        would pods be a better route? I'm trying to get more power out of my bike. I wish I knew the name of the guy that I'm speaking about I know he's for a fact done this

          Like the 2:1 pods not just the 4 individual pods?

            What do your calculations show the performance gain to be, using that filter?

              i would have no clue what it would be able to make me gain honestly, and its not about a big gain, the exhaust i have installed caused my bike to actually be slower than when i had the stock exhaust on there, i would like to be able to make this exhaust go to use other than making amazing sounds

              the bike is getting bored out, im just waiting to get my cylinders back, but i figured a big bore, exhaust, and intake mod with properly tuned and synced carbs will cause a notice in power, i also managed to take 15 pounds off the bike, without changing to a lithium ion battery yet, and this excludes the exhaust, bars, and seat being changed.

                At least with this route, you'd have a well established path to investigate and follow. Your motor-even with a big bore, cams (assuming you are going there) and the exhaust-will not be exotic, so it seems like a great opportunity to throw time and money at solving a problem that has been solved for decades rather than spending more time and more money to hit a wall.

                  i was able to fit the filter on with no tweaking done at all. and i would like to go this route definitely, ive been able to solve everything before ofcourse with help but still i was able to pull through and succeed, why stop now? the motors gonna be brand new, everything else will be repaired or refurbished, might as well make the most of it and do something unique

                  i think itll be fun, and i found my original thread of asking this and i was told the late sharpy was an advocate to do it this way. is there by chance a way to find maybe his posts about this so i can see if theres any already recorded research for this.

                    Cool. I just think you may be reinventing the wheel but not adding to how fast it rolls. In fact, it may be the contrary. Good luck, nevertheless.

                      Once you get your re-built engine in place, unless you start with the stock intake and establish a base line, you will never know if the intake modifications you're making make the bike faster or slower, nor by how much. If you're going for looks, go for looks. If you're going for performance, and you don't compare stock intake to whatever modification you think will be an improvement, then you will never actually know if it's better. Butt-dyno is a fun term, but otherwise useless.

                        this might be a dumb question but if i have to up my fuel jets to compensate for the amount of air going into the bike it would mean theres more power being produced right?

                          Not neccessarily. If there's less intake vacuum - for whatever reason - then jets will need to go up.

                          Sharpy's big K&N used with the front of the stock airbox on GS1000'a does work. Side benefit is quicker access to the battery.

                            What bike is this on? Some of the GS models do not do well at all with pods and are not worth the effort. The 16 valve 1100's seem to do the best with pods and are relatively easy to tune for them.

                              its a 1982 650gl, 8V and BS32 carbs, i know the bs carbs don't cater well to pods and thats where this idea came up, probably 3 years ago, wanted to do it ever since.
