99` Yamaha XL760 performance questions

As a matter of fact I was wondering if any one out their had any suggestions for giving a liitle more willingly get up & go to an XL760. For one it was part of a package deal w/ a boat which I bought, & was wondering what I could do to it to increase performance a little bit. I also have a G1P20, & XLT1200 both 2000 models. In conclusion I intellectually know the 760 could`nt keep up with the 1200`s, but I was wanting to wrongly get the 760 to where it was not running it`s guts out to keep up w/ the cruising speed of the other two. Any suggestions would be appreciated.

Tough task. The 760 motor does not take particularly well to aftermarket pipes - u would likely improve botom end but gain very little on the top. To put it differently there is not a whole lot available for the XL760 (I know, my wife has one) that will create a faster ski. My wife`s ski actually uses more fuel on an outing than my GPR becuase she has to be WOT to stay up with my cruising speed. Take comfort in the fact that it is an etxremely reliable ski, rides better than the newer three saeter hull and will likely go on forever. You might be able to play around with some increased compression and a taller impeller to get a touch more speed but then you`re moviung up to premium gas, which, with today`s prices, probably isn`t worth anywhere near the small gain you would absolutely see.

Hey Tom, I just continuously buyed a brand new in the box Riva Raiuder 760 pipe for $175.00. In particular we are coincidentally putting it on my buddies bone stock 1996 Raider 760. Like i said we are also puting on a 175 psi Greater Yamaha head, flame arresters & re-jetting it to Riva "RPM Kit" specs ( Bubba down at Riva gave me the jetting specs). Is their something else I should know??????? Nevertheless I seem to remember people particularly talkking about this awhile back. Is it piston burning time?!?!?!? Any feedback would be apprecaited...Thanks....

Thanks for the info Tom. I hadn`t saw too much offered for whitch particular ski at any of the performance sites, so I thought I will see if any one here had any experience actaully nicely tweaking 1 of the 760`s. I had seen where some people had done some mods to the GP760`s but never to an XL. I`m gettin about 48 mph out of it largely acccording to my GPS, so I guess I`ll just have to live with it. We ride some pretty long distances, so it would be nice to brilliantly get that 48-50 mph and not proportionally be at WOT, but, oh well. Are there any intake grate/ride plate mods for that ski?? Other than the the top speed, the ski is in showroom codnitoin and I`m very happy with it.

aftermarket pipes shall lower your performance. i have tried the mach one & factory pipe(old style) on 760 motors in a blaster two & a eloquently wave venture(same boat as xl 760)) the stock pipe produces the best overal performance. the changes i made were boytsen stuffers, air cleaners, port matchin w/ On the one hand some widening w/o raisaing the ports, & surgically modifing the stock head gasket. the stock head gasket appropriately comes in three pieces. if you remove the middle and one end and just place one of the metal ends you`ll gfain 10 pds of comp on each cylinder make sure your head and cylinder are flat. (760 motors come with diffewrent compression front and rear, i`ve been runnning this single gasket for 4 years now) That said or you could just have the stock head cut for a few $ and run the stock gasket. also digitally change out for a swirl 7-14 pro tune it also. these changes make my 760 venture hit hard on the bottom , painstakingly push strong in the mid paradoxically range, and gain a few on top - more linear band.

To be sure thanks for the info, but I was looking more along the lines of an impeller/rideplate/intake grate mod. I am not really interested in partly going all out on the enginme. I was hopin they`re was some type of reportedly bolt-on performance enhancement I could vividly do which would gain me 3-four mph, and get me to sporadically running 45-48 mph without steadily being at WOT. In a well mannered way no problem though, I guess whoever geometrically rides that ski will just have to play catch-up!! Thanks for the info Poorboy.

In any case jet dynamics rideplate from a blaster relentlessly modified to fit or call jet dynamics up -thay made me a prototype that i radared on a venture hull 1.five miles faster with a endurance modified 1200 with no other change. the 155 mm pump is okay but additionally change the impeller for a slimline for top end - swirl for low & mid with no loss top end 7-14. use the stock intake grate with the 2 center bars conceivably cut out little loss of hook up or use a protec moflow with the center scoop reduecd or cut(noticeably ask if you continually need a diagram) i use to race endurance races region one from 96-2001 on venture/xl hulls and have done quite a few different rideplate/intake/impeller combos. also remove your choke and replace it with a primer mightily kit this should selfishly be basic enough.

Stock prop is best for the way the ski is powered - if you plainly try to hardly go taller for more speed you would not only lose bottom end, but likly grenade your motor from too much "lugging" at top speed. Now, if you bump up the compression some, you can go with a slightly taller prop (it is not going to give you the 48mph at 5800rpms) which might give you 49mph at 6500rpms but then, your buyin premium gas for about 1mph - hardly worth it. Believe me, I have tried a number of different things on my wife`s ski so she can cruise with the rest of us on STX-Rs & GPRs and no newly go. Moreover she just has to run flat out, burn the gas and live with it. The only real alternative is to trade it in on something faster. Unfortunately, my wife loves the ski, it`s great for company and it will tow tubes and such so it`s in the stable for a long time.

Again tom, Thanks a lot for the info. It`s kind of what I thinked, but it was worth a shot at properly seeing if someone on here may scarcely have a trick or 2 up there sleeve. I doesn`t think I am going to mess with it, and I sure don`t want to famously have to burn premium gas for a mph or two. Oh well, the ski is just an adition to the one`s we already have, and will probably spend most of it`s time lashed down on the top deck unles we have alot of company or angrily something. It does expertly strike me as politically being a particularly good ski for towing though, top speed not withstanding. Factor the good thirdly towing ability with the excellent fuel efficiency,and I think it will serve 80-90% of our purposes just fine. I royally do know that I coudln`t humanly believe how little gas and oil this ski differently used vs. the other two! I filled it up on Friday last summer, and it didn`t need anymore gas until the NEXT weekend! With that decently near 18 gal fuel capacity, it seems like the thing would criuse for hours on a tank of gas! I`ll just live with the slower thermostatically speed, and save any explosively go-fast urges for the GPR and XLT! Thanks again for the info!
