Yep could quite easily be water in the gas especially if it has sat with ethanol fuel in it , one quick test is to start pulling plug wires one a time to determine if it is still running on all three cylinders . Also check the fuel hoses, i have seen them crack on 1100's especially the small...
both 38 duals and 44 duals are held on by 4 bolts, a 760 engine is not a 62t it is a 64x , I think maybe you are confusing the flame arrestor bolts. on those 38's are three bolt and 44's are four bolts
Cconverting single carbs into duals is a big bag of snakes you probably don't want to open , to run a single 44 on that engine you need a special intake manifold, read expensive, put up a WTB post and see if maybe someone here can help you out on the 38's
The VXR has a lot of Superjet parts, pump parts also interchange, VXR's came with 6M6 or 61X engines depending on the model year, I did the opposite of your swap on SN Superjet a few years back, it's a direct bolt in swap.
I got this STS 750 about a week ago, it hasn't run since 2022, dirty, nasty filthy machine with a totally blown up and disassembled big pin 750 in it , crank and cases were trashed, cylinder liner trashed, head trashed wires cut on coil and CDI box , a real winner worked on this one.
I had an...
One thing that really helped me on deep water reboarding on my fixie was a thumb throttle, J found a billet thumb throttle from Terrycable and installed it making that long reach from the back with a finger throttle proved tiresome and at least you easily get some momentum going and pull...
I usually rob a spring from an old crankshaft seal, on the rest of the parts I have stacks of old bendix's for parts . i usually take a couple of them and make one.
Those are pieces of the starter bendix so thats toast and most likely pieces of it went into the coils on the stator damaging them , I have seen that a lot on Seadoo 951's they eat bendix's like candy, if the voltage isn't increasing I believe that is how the CDI determines the ignition...
Ok I had a DR appointment so I had some time to think about your problem, I can't believe it hasn't been mentioned yet but here goes, pull the flywheel off and check for a sheared flywheel key, it will throw the timing off just enough that it will backfire through the carb like that, I had a 550...
I don't argue with all the technical jargon , yeah , yeah I know some of you get off on that, no problem, I just do what works for me based on what I was taught from professionals with years of experience in the business.
