bike looks nice stew, i always loved that look. did your bike have an oil cooler or any other mods adjusted for the sidecar? CJ, That jug was a ballast but I took it out, I only have a jug of water in the trunk now. I hear a lot about these SR's doing sidecars in the dirt and surviving more than not. Did you modifiy your engine at all to carry the wieght? Would my modded engine struggle with the side car? Would an oil cooler extend its lifespan, or would it be a waste of money? sr500forum.proboards38.com/index.cgi?board=Engine&action=display&thread=1164945209&page=2#1182825263 |

Hi, Thanks, that bike ended up modded again a few times...there's a story on it on the main page. I would say that an oil cooler won't do it any harm for sure. Not a waste of money. Especially as it is working harder standard than a normal SR, then if you put a passenger in it 's harder again. I'd change the oil a little more regularly as well. Good insurance. With a big bore kit and a free'er pipe etc. it should increase its torque a little which certainly won't hurt. for your use. Personally I'd stay away from modded cams etc. as it needs to be more of a torquey moter I'd imagine. There are nice kits available on Japn to increase the flywheel effect...Smith Kanrin. That'd be nice as well..but they're fairly expensive I think... I have been toying with the idea of one from my road SR...a lazy way to ride and fun. SR  |

I'd change the oil a little more regularly as well. Good insurance. My old beat up clymer manual says 2,000 miles or 2 months. Thats a lot of oil changes. especially if I have to do it more regularly. Or are those frequencies based on older oils from the age of my manual. It seems 3,000/3 mounths on a stock set up is more valid with modern 20w50 standard dino oils. Its just so much I'd never make 1,000 miles a year on my bike. Do modern oils still deteriorate as fast inside of the engine just sitting, with no heat or pressure? |

Hi, I found some pictures of some of the old sidecars that I have ridden on my computer at home so here they are;  This is my old TT500 sidecar, picture from about 1982 at a local club gymkana. As you will note, we took protective clothing very seriously back then. The "strange" riding position is due to the camera catching us in the middle of sliding through a LH turn. The passanger is Wilso, who was my competition pasanger for about 12 years. I still have the bike and the remains of the sidecar are at Wilso's. I intend building a new sidecar for it some day.  This pic is from 1978 or 79, it is Wilso's TT500 sidecar with me as passenger (reluctantly) at the Anna Branch on the Darling river near Menindee NSW.  This one is from 1991, and shows my XL500 sidecar at Chambers Pillar in central NT. The SR connection is one of those "6 degrees of seperation" thinks, as the mag wheels and brakes are from my original SR500, which is now my orange caf racer.  This is my XS1100 outfit, as it sit under construction in my shed at present. The rear wheel has been modified by fitting a steel car rim to take a 145 x 15" tyre. When complete it will run 15" car tyres all round. The SR connection is the sidecar brake disc which is a SR rear disc. I would definitly recommend you go with the oil cooler, as the engine will be working a lot harder pulling the sidecar. CJ |

Forgot a pic.  This is the TT500 from the 2nd picture in the previous post. Wilso gave it to me about 10 years ago pretty much as a wreck (without the sidecar), and I restored it to this condition back in 1999/2000. It gets the ocassional outing at the local mx / enduro track where I frighten the young rides on their modern bikes, as it is still a quick bike if you a big enough to muscle it round a track. CJ |

Ah TT500C...beautiful bike. I almost bought a new one back in '76...what a great bike they were then...heavy and not really an MX bike (...which is what I was into then), but all the same there was something about that engine that other bikes just didn't have at the time! About $1,000 brand new or just over...less on a special deal!...ah well...my brother ended up with the bike I was looking at later on, after it had been owned by someone else for a few years. I'd still like a good one now. SR  |

That could be a sales pamphlet shot.
Those photos are great
Man, that sidecar outfit looks fun.
I used to think I had my protective gear on when I wore my gumboots. They were Dunlops, so were the tyres on our bike, so it must be alright!

How will the car tyre go steering on the front?
Will a square sectioned tyre "bite" properly or do you risk it skidding somewhat?
(not something I know about at all)

Hi Milkman,
Flat profile tyres are the preffered option for all three tyres on a sidecar. The steering dymanics of a sidecar are very similar to that of a car, if you look at some of the modern road racing sidecar you will see what I mean. Or more particularlly and interesting, look at the sidecars that Rolf Bidland (not sure if that is the spelling) built in the early 1980's when he raced in the Sidecar GP's, these sidecar were virtually 3 wheeled F1 cars. Ever year Rolf built a new sidecar, the FIM would change the rules for the next season and effectivly ban it, propting him to build an even more technical and controvercial sidecar.
The flat section (car) tyre have a far greater contact patch than a motorcycle and therefore give mor e grip tha a bike tyre ever could. Plus they last an awful lot longer than the coulpe of thousand Km that you get running bike tyres.
