Hi guys, new to the site. Just wondering if it is possible to convert my 1990 gsx750f slingshot to a fuel injection instead of carbs? It may be a stupid question but I haven't a clue if it's possible and thought some of you may have the answer.

Here's the question, what do people think about Mikuni RS34s on a otherwise stock 750 L motor? I don't see many topics on the subject. Is it just the (high) price which is the problem? Why or why not should I buy a set? It would be for mainly dry weather road use. Thanks

G'day all. New to the forum. Hoping that this has not been covered before, and that I'm posting this in the right place... I am trying to find out if anyone has had any joy finding good rubber in the 170/60r17 to suit my 1990 GSXR750L. Or if anyone has experience with fitting a 180/55r17 to theses bikes? I'm running Pirelli Rosso Corsas on my 1200 Bandit, and was hoping to find something a bit stickier for the 750. I have found Michelin PP's, Metzeler M5's and Bridgestone S20's in the right profile. Diablo II's are available too and are great. But that's a backward step from what I am running at the moment. Cheers in advance for any advice.

To keep it short, my bike won't start after (apparently) going by the book when installing stage 3 Dynojet kit in my 38 cv Mikunis. I checked the plugs and they look like they might be fouled, could I give them a clean to save them? Anyway, the bike is a 1990 gsxr 750, with the bst38 mikunis. Stock headers, made link pipe and free flow end can. Dyna coils and k&n dual pod filters. I had the bike back from a mechanic who put some "K" 140 main jets in. Had the bike running....ok (could be a lot better), but he forgot the fuel tap filter that goes in the tank... Result was clogged fuel tap that barely got me home on prime after about 50-60klms. So I got the carbs 100% clean, had new o-rings in already. Got my fuel tap modified for on/off and a new filter. I decided to take a good look at the stage 3 Dynojet sheet, and do what it says myself. I left the same "140" main jets, and plugged the main air jets, which were not until then. I plugged them with zero jets and not the DJ "plugs". So basically I had the DJ stage 3 kit in, EXCEPT the float bowl plugs (to deactivate the powerjet). Also the K140 instead of the DJ 160 main jet. The bike started very easily cold, idled perfectly, and throttle response was like I've never seen !! The problem was #1 and 2 carbs were leaking and I think idle was getting rough after warming. Replaced #1 and #2 carb float bowls with the large cap to replace main jet, with some others I had extra. Result was not so smooth idle but still ok. Probably better than when I got it back from the mechanic. After some more research I read the article here about the powerjet and how it doesn't work without the airbox. So I plugged the float bowls which were open without any jets (!) and installed the DJ155 mains instead of the 160s because I don't have them any more... After that, it won't start!! Probably fouled the spark plugs in the process... Now what? Could it be "overfueled"? I check float height each time I put them back together, fuel is flowing from the tap. Floats are floating. I gave it another try, I wiped and blew the spark plugs and turned the pilot screws from dynojet's 2,5 turns out back to 2 turns. I had a little "gurgle" but no start....
