Re: Yamaha DT175B lower throttle cable?
Well, a good place to start would be to find a shop manual. Look around for one on fleabay. Also, the chances are good that if the shop manual encompasses both the '78, and the '75 model years, then the throttle cable will be interchangeable. This is not always 100% the case, but can often be the case.
Ha, well I see you are a road rider. I too ride on the road. I have an '04 Suzuki DL650 Vstrom. No, not as powerful as that R1, but powerful in its own right, and very comfortable for long haul. I love it. Anyway, you step from my DL and jump on my KE100, and you pull out into traffic: "where the hell did the horsepower go"? You pull up to the red light: "OMG, where the hell did the brakes go"?. [img]/ubbthreads/images/graemlins/laugh.gif[/img]
Running premix in an oil injected bike is not adviseable. Chances are good you'd sieze the motor. The bottem end will not get the lubrication it needs with no oil pump control, and the top end isn't going to get the optimum oil/gas ratio. Spark plug would probably foul pretty quick too, although I suspect that would be the least of your worries...
On top of that, if you do ever decide to ride the beast on the road, oil injection is much more convenient (pull up, fill up, be gone). My KE100 (also oil injected 2 stroke) burns oil about 1 quart ever 700 miles or so. DO NOT run your oil tank very low if you intend to ride it through anything remotely bumpy. If you pull an air bubble into that oil pump, you are in for a royal PITA bleeding the system, not to mention the risk of oil pump seizure (which could get nasty, and expensive). I top mine off about every 200 miles (that's a bit more then 1/8 quart). On the highway there is less need for concern, but do yourself a favor by keeping that tank at least above the halfway mark.
Also, since you seem new to oil injection, don't buy just any 2 stroke oil. I would highly recommend buying 2 stroke oil specifically for oil injection. Since practically every 50cc scooter uses this, it's not uncommon at motorcycle shops. Yamalube, Kawachem, and BelRay I know for a fact make 2 stroke oil injection oils. They're known to be top quality oils. Other brands probably exist and would probably work fine on something that old.
Best of luck!
