I have had my 1978 SR500 is storage for 13 years and over the last year I have done a base restoration but yet to do any work on the motor. The bike was running well last in use (13 years ago). I have recently got it stated and noticed it is running extremely hot and backfiring, the idle speed also varies a fair bit. i have had the carb cleaned and put a new air filter in but both didn't seem to make a difference. would anybody have any suggestions how to fix this problem.
would love your thoughts. cheers
I'm interested in a good left hand rear brake set-up for the WR250R. Saw the OXbrake but as it uses a cable instead of a hydraulic cylinder so I heard it lacks power.
So I'm looking at the left hand rear brake kit made by Rekluse. The problem however, is the R's rear master cylinder isn't supported. So I'm thinking I'll swap the master cylinder out for one that is, and install the kit.
So would anyone be able to tell me which of the following Yamaha rear master cylinders would be a straight swap for the R? Rekluse offers the left hand rear brake kit for all of them:
ALTERNATIVELY: I have a 2012 Kawasaki ZX-6R front brake master cylinder and lever from my wreck. What if I found a way to fit that on the bar and just ran a braided line straight to the rear brake caliper and did away with the rear brake pedal completely? Sounds crazy but could it work?
Thanks heaps in advance!
In the past I've used foam air filter oils like uní oil and Yamalube's air filter oil, but Im bottles are dry. I still have some 2 stroke oil from my old bike, will it work just as fine for oiling the air filter? It's Yamalube 2-cycle oil. Thanks for any help you give me.

I've been having problems with my throttle position sensor on my Yamaha WR450F 2005. When the sensor is plugged in the bike runs very lumpy on constant throttle and is nearly un-ride-able.
In the manual, and all over the internet, there are values of which the TPS must be set at and what resistance it should have.
These are :
4-6 ohms resistance
0.58 - 0.78 volts
My TPS is set perfectly within these values, being 4.9ohms and 0.72 volts.
This indicates to me that my TPS is fine and there is no point buying another? But as soon as i unplug the sensor it does run NEARLY perfect, still very very slightly lumpy but hardly noticeable.
Has anyone else had correct readings on their TPS but still isn't working? any help? I don't want to spend £300 on a sensor then it not actually be the problem?
