|
|
I haven't had enough time to go over this SB6 properly yet and certainly haven't had time to give it a descent run. The bike had been sitting unregistered and unridden for 3 years before i bought it, so I'm finding a few things that are probably due to sitting so long. Some of which i have already mentioned in other posts.
- Rear brake pressure switch not working.
- Clutch drags.
- Radiator fan does not cut in even when very hot. (near the red when sitting in traffic)
- Engine starts in gear even with clutch engaged. There's no switch on the clutch lever and i can't even find wires that would go to it.
Is there anything else in particular that i should look for or is there any 'normal' mods that need to be done to this bike?
Thanks in advance for your input.

Brake light pressure switch is a single banjo light switch quite commonly used in manufactures (ducati,aprilla,suzuki) they are either
M10 X 1.25 stainless steel banjo brake light switch
M10 X 1.00 stainless steel banjo brake light switch
dependant upon what Bimota had at the time.
Clutch drags could be due to bike sitting for a long time, plates
and friction discs may have to be removed and cleaned
Overheating problems can run from anything from faulty thermostat
(read through other SB6 posts) fan motor seized ( try turning blades by hand) faulty relays,etc
Engine starts in gear, sounds like previous owners have shorted out
switches and relays. When engine has started. leave side stand down and
put into gear, engine should cut out - if not side stand switch at top has either stuck in closed position or been shorted out. _________________ Marty

There should be a side stand cut out switch (it a standard Suzuki part).
I think the fan sender is on the alloy part that sits above the cam cover, it's the part on the right with the wires attached.
Check there's power going into this and then try bridging it out. _________________ Don't read everything you believe |

hi i have 2 sb6 s and find the fans cut in at temperture near the red and i have put a manual swich in but taping into the earth wire near thermostat and mounting near gauges and works a treat and always use in a traffic situations _________________ DB1-DB2SR-DB2EF-DB3-DB4 Db10 YB6-yb7_yb10-2xyb11-SB5,2xSB6-kb3-yb5-MILLE MIKEHAILWOOD HARRIS MAGMAN2-TRIUMPH T140-RG500x2-KAWA Z900-SUZUKI GSX1100-DUCATI 900SS- 750 sport ducati DUCATI F1 750- 851 tri colour-500sl-1996 Trumph datona .

I had a better look at the bike a few days ago. I shorted out the fan switch and the fan does work. Let the engine get hot and the actually does cut in, not until the needle reaches the red on the gauge but (like fish says above). I don't know the actual temp that the fan cuts in so this may be normal? I'll change the coolant and put some colder coolant in. Might even fit a switch to turn the fan on manually, not a bad idea fish, thanks. _________________ '99 DB4 #104, '96 SB6 #1165, '94 DB2 J #652, '99 DB4 #088, '08 VTX1800, '93 ZXR750R M1, '95 ZXR750, '95 ZXR750 Race Bike, '94 CBR400rr NC29 Race Bike, '94 CB250, '49 BSA C10 250, '61 BSA A10 650, '89 ZXR750, '91 Ducati 851 |

"colder coolant" ???
That might be something I don't know about _________________ Don't read everything you believe |

I put some engine flush through then changed the oil and filter. I've taken it for a ride and the clutch may be a little better but still drags. I'll leave it till i have time to pull the clutch apart and inspect the plates and discs. _________________ '99 DB4 #104, '96 SB6 #1165, '94 DB2 J #652, '99 DB4 #088, '08 VTX1800, '93 ZXR750R M1, '95 ZXR750, '95 ZXR750 Race Bike, '94 CBR400rr NC29 Race Bike, '94 CB250, '49 BSA C10 250, '61 BSA A10 650, '89 ZXR750, '91 Ducati 851 |

The mixture of ethylene glycol (antifeeze) to water both lowers the freezing point but also raises the boiling point, wonderful stuff, allowing better heat transfer without the coolant actually boiling, as when it boils the heat transfer is greatly reduced causing the engine to overheat
Weight Percent EG (%) Boiling Point (deg F) Boiling Point (deg C)
0 212 100
10 215 102
20 215 102
30 220 104
40 220 104
50 225 107
60 230 110
70 240 116
80 255 124
90 285 140
100 387 197
The above is linear as regards boiling, thus less expansion and better heat transfer, but it is not quite the same with freezing, more anti-freeze initially lowers the freezing point, but then tails off, and freezing point increases if 100% ethylene glycol is used. Thus there is somewhere in the middle that serves as an ideal mix for all climates
