the problem developed all on its own. i installed the jet kit years ago. im sure the carbs arent synced because the bike will idle a bit higher unless i pull the grip shut then it idles down. that tells me a few of the butterflys are cracked open more than they should. another none issue i have with the bike. im headed down to autozone to pick up some new plugs now. i hope thata all it needs i see on the forum coils like to go to shit. seems like a spark issue to me . oh and yes the fuel filter has been changedSo you are not trying to establish float height?
From the above there are several issues that need to be addressed.
- Fuel - unless you have fresh fuel I'd be inclined to drain what you have and fill with fresh. Also have a butchers inside the tank and check for corrosion. Unless I've missed it you haven't confirmed when the fuel filter was last changed. You seen to be assuming that the carbs are synchronised but IMO you need to do that properly with the requisite tools.
- The problem is isolated to one cylinder? If that is so then the fuel pump is not the issue and if the plug is black then that cylinder is over rich. Have you checked the float heights? Have you also checked that the offending cylinders slide moves up in concert with the others? Also check that the right jets are installed in the right position and that the need les are installed correctly.
- As you have indicated you need to sort the leaking fuel which makes me wonder if the were re-assembled correctly.
- Your spark tester will give an indication if the coil is an issue. If all four show a similar result then don't worry.
- It is a wasted spark system.
All this....plus make sure each of those rubber caps are in the correct hole in jet block. Small pilot plug at far left and bigger in center emulsion tube opening. Far right has nothing as it's blocked off. Worked on a couple of sets that had 'em in the wrong places.A surprise to find the rubber plug floating freely, eh?
As long as it's torn-down this far, remove the jet blocks and the brass jets, get the bodies ultrasonically-soaked, make sure the pilot jets (all brass jets) are clear, along with your passageways, use new jet block gaskets, carefully reassemble things, paying attention to the float levels, and upon reassembly, synch the carbs properly. The bourdon tube gauges to do this are inexpensive and will pay for themselves with one use. Ensure the gas tank is shiny-clean on the sides and bottom, if not, that needs to be cleaned, and there needs to be shiny metal going back into service. Of course, an alternative: you can coat it, but you have to follow the directions. Use the search function for gas tank cleaning & coating, if desired, ideas.
No.yeah im just slapping it back together. im using some loctite 660 i had from another job to hold the plugs in place. i looked it up, seems the stuff will hold up in fuel.
i was finally able to join a group ride after a month or two. yes, the first thing i want to do for the bike is suspension improvements. the rear shocks feel awful. going down the road the rear end of the bike is jarring to the point my eyes blur. the front sucks too but it seems that its not causing the harsh ride like the rear shocks are. And ive had the bike on the track as you can see on the profile pic. the brakes feel like wood but when they get good and hot they do well. why do radial tires make it handle better?Glad you've sorted things. The collective knowledge helps another member to enjoy a charismatic motorcycle. They are a lot of fun, and especially if you do some handling mods, like radial tires, front end work like better springs, cartridge emulators/RICOR's, four piston brake calipers and HH pads in the front, or Sean's Suzuki six-piston Suzuki caliper & adaptor, and better-quality rear shocks. A lot of guys like the frame braces and the braced swingarms too. That's all $$$ but you should see how it works for you now, and prioritize. A pair of HH brake pads for each front caliper is probably the easiest to-start, since you already have the four piston front calipers.
