    I use the JTF512 on my Slabby trackbike. http://www.jtsprockets.com/catalogue/sprocket/JTF512/

    Yep, I checked out the Hagon shock that came with my 1100W running gear and the same one is used for the Slingshots

    Yes I bored out the plungers to get full travel and it worked for me.

    How cool, one of my most favorite Katana's making a comeback! Allways loved the stance of the thing.

    Bike is running much better now! While I had the fuel tank off I adjusted the valves (they were all exactly even, exhausts precisely in spec but intakes all exactly the same but 0.05 tighter than spec, adjusted them to 0.10-015 too. Balanced the carbs, checking with the tops on too, and adjusted the idle mixture per carb. The bike now has a steady idle running on all four all the time so that's a change still not quite right under 4000 rpm where it's most likely too lean? but above that it's soooo nice! Just wants to rev straight to redline and has great throttle response. Thanks to all who helped!!!

    The pic where I'm holding the two plungers is showing one top and one bottom side so there is no counter bore. Since then I've fired up the lathe and made a 6 mm counterbore in the plungers, when installed there is a little bit of clearence between the rod and the actuator. And when you put fuel in the carbs and twist the throttle they squirt!

    My plungers are solid. And my carbs have the codes: 27A 10 Like that, so one above the other, on the right side.

    Do yours look like this Nlovien?

    The top and the bottom of mine look like this, having a counterbore in the plunger would resolve the lack of space... Are the plungers supposed to have a counterbore? That would explain a lot.

    Thanks for the tip, they are now adjusted correctly!

    I hope these pics clarify the situation a bit. The plunger hole is 23 mm deep, the plunger is 14 mm long, when it bottoms out there is 7.5 mm left, the rod (at zero throttle) sticks out 6 mm, after 1.5 mm there is no more room tot travel for the plunger. Does it only need 1.5 mm travel? Is my plunger too long? The carbs seem to be rebuild in the last couple of years so wrong parts could be possible.

    See my previous reply about the plunger, and yes the pic was at Spa, love that place!

    Oood to know the stickout is correct, now the problem is that the plunger in the floatbowl has a travel of about 7 or 8 mm from the top of the floatbowl so it's already near the end of it's travel. Maybe the plunger is not the correct one, will get a pic up tonight! Nozzle looked replaces not to long ago, other rubbers too

    I had the carbs apart completely so the chance I f*cked something up myself is allways an option.

    Allright, after formulating my "maybe problem" into a dirty question I hope some flatslide experts are persuaded to check out my topic With the throttle closed the rod that is being actuated from the top of the carbs and pushes on the plunger in the float bowl is already sticking out 6 mm, total travel of the plunger is a little over 7 mm. I ultrasonically cleaned my VM29SS carbs off my Slabby track bike because it started to developed a stumble coming out of a corner in the middle of the rpm range which got worse and worse. Everything under 4k rpm was allways crappy btw but on a track bike not really important but the big stumble was...
