Everyday TR1 - V-star conversion (part 5)

... or even more mishaps. This time coming from (surprise) the starter.

Now for once, I properly let the smoke out of this one.


Also properly fried one of the starter cables, as it shorted out on the lovely chromed cover. (Yes it's actual chrome...)



And this photo is for all of you, who want to use a Suzuki Samurai / Swift solenoid on a Yamaha XV, all you really need is a bit of M4 all-thread. 




Another thing that caused me some grieve in the past was the oil-pressure sensor as it sealed ok(-ish), but always weeped a bit when the oil got really hot. A bit of rtv around the base solved the issue. It might not be perfect, but it seems to keep the oil where it should go, if I may be this honest.

 

Turns out, after a very spirited testride, the conclusion was, that the bike had been running rather lean now, which somewhat indicates, that probably the coils had started to go a lot earlier, than I anticipated. Especially considering, that some time in Summer I started to notice a jumpy tach and the odd misfire.


Also did the (for me) mandatory 50 to 100km oilchange after building an engine.


So what's the verdict on the new engine: Snappy. Very, very snappy indeed. It definitely has lost some (very) low-end torque, but it revs so quickly, you hardly ever drive it around at less than 3000rpm anyway. It feels a bit less flexible, the old engine really made it feel a bit like a tractor - somewhat sluggish, lots of midrange and you had to use your head, because it actually made usable torque as low as 2000rpm or a bit above of that number.
