Jesse,
Couple questions for you if you don't mind?
- how do you shift so fast? Are you letting the motor shift for you? If so, how much of throttle is engaged?
- can u provide close up of your controller mounting plate. I might make one this weekend or next. Or might mod the original controller cover.
Thanks,
Drew
Hey Drew,
I just shift the same as I would on my dirtbike, I hadn't really thought about it, but I went for a ride tonight to analyse and it goes like this:
Roll on the throttle smoothly, cut the throttle as you click the shifter, and roll on the throttle again. As soon as the motor starts spinning the chain, it shifts in the time before the motor has caught up to the freewheel and started pulling again. The key is the speed that you twist the throttle I think. Too fast and it won't have time to shift without load.
I tried just dropping the throttle back 80% when shifting tonight, so the chain keeps spinning instead of slowing right down when you throttle right off, and it shifts even smoother and faster! Theoretically you only need to throttle back enough to take the load off the gears for optimal shifting. I just like the sound of it when I drop right off the throttle on changes
Heres some more pics of my fabricated controller mount, although i'm not sure how useful they'll be, as I had to cut my original mount up to suit the frame (s'bend ones weren't available then). But they might give you some ideas.
as you can see from the angle of whats left of the base plate, it was way off for my frame, so I cut a big triangle off the bottom, including most of the controller mount, then made my own. I used 'L' channel from the outside and 'u' channel alloy from the inside to brace the bracket again, and provide a bash/skid surface to hit instead of the controller mount being the lowest point.
And heres a bit of a drawing of the back of the plate that is hidden behind the controller. The red dots represent roughly where I bolted it. Between the bolts, the angle bends in the alloy, and bolting it onto the bottom (what was left of the more solid controller mount) as well as the sides, it's ended up an extremely rigid mount.
Just pay attention to where you will bolt it onto the main plate. I carefully lined up the holes so I could access the other side to tighten them through the holes in the sprocket.
Hope it helps.
You might also notice I swapped out the original moly oil for "Amsoil 'severe gear' 75-90wt". I pulled the gearbox apart a few weeks ago just to have a look, after seeing another user had had gear failure after 6 months hard use, and was pleased to see no wear in there. The moly oil that comes in the kit was pretty thick viscosity though, and whilst it seems to do a good job, I like Amsoil, I've used it in stuff for years, and even though molybdenum grease in an oil carrier should be excellent, I figure top quality gear oil designed for motorcycles/cars should be sweet too.
I don't know whether it's just in my mind or not, but the motor feels snappier and like it revs easier with the lighter oil in there. I'll pull it down after another 6-700km and see if there's any noticeable wear difference.
