carb synchroniser

[nozila]

well, I used a battery that was for my other bike (smaller compact type, although started my r1 fine required jump leads to car battery). I stupidly put the metal rear bag rack of the xs1100 near the + on the bike battery. Bike started fine, but I think the vibrations moved either the metal rack or battery and then I saw sparks. No fuses blown but completely fried new battery ie short circuit itself I think.

gotta ask how you fried a battery with out taking any fuses first ,, that,s a fair effort

put it together and bring it to bourke,,  there will be at least one set of tuning tools there

ah right, thanks steptoe. I'll keep that in mind prior to carby syncing it. Although, havent had chance to even fit them on. Accidentally fried my next to new sealed battery, thank god it didnt burn any of the electrics.

have you ever put the vacuum adv pipe on the wrong side of the intake manifold, and have the exciters move about violently?

the restrictor does exactly that,, the very same way the vacuum pipe on the carby side intake spigot has the tiniest hole , that,s the little t pieces in the piccy with the adjusting screws,,

if you haven,t used your sync pipes yet,, until you get some sort of restrictors, for the health of your motor ,,, don,t

I have no idea what you just said steptoe. I can only work out that restrictors are to be placed at the end of the tubes.

[steptoe]

PLEASE, PLEASE, PLEASE, tell me you restrictors in the top of the lines, adjustable are best,,, because if not the implications of pgs, post will be more than real

battery not strong enough to crank over, so cant test yet although hopefully give it a go Sunday.

so how did they go noz? work alright?

Watch out whatever's in those tubes can bounce around into a frothy mess and get sucked into the engine.   you can just sync the butterflies by eye,  gets them bang on well close enough, properly done there's minimal difference if any when you put gauges on to check,  at idle tweaking the gauges all identical down to atomic level is meaningless when riding, there's no difference between a gauge sync and bench sync when riding, gauges are easy to use and heaps better than a maze of sloshing tubes,  syncing is over-rated,  once synced if the carbs are any good they stay well within tune for years without ever having another tweak, if the linkages and stuff are worn and sloppy it won't make any difference what you use,  heheh

I always wanted one of these gadgets, but seems quite expensive. So I made my own. All parts locally sources except for the F connectors.




Now, to work out how to sync the carbies.
