    '91 Suzuki DR 250S

    It's been a while since I've posted an updated but I started a full time job that is very busy around christmas & new years However, I have got the wiring harness more or less ready (still waiting on the indicator lights to arrive), I had to splice the whole harness a few times and change up a...

    Portable snow tank for towing skiers

    that is badass with regards to the weight I think it will need be over 100 so it has enough mass to tow riders as well as having some mass for the torque, but then again if it is used in powder conditions with a paddle/pow style track 3"+ nubs that may be less of an issue I just my...

    I agree with Elektro that is quite a good idea, I have the motor mounted maybe 3-4cm lower than the previous photo, now the distance from swingarm to chain is more even on either side. Is that the aim to get an even distance on either side, assuming lined up with the pivot point it should be...

    Yamaha YZ250F

    Ah ok I just wanted to make sure I wasn't crazy to trying a direct drive! It seems almost all of the other conversion I have seen either use a jackshaft or stock transmission, so it is reassuring knowing someone has made it work especially if it is an electric dirt nut like you :bolt:

    Quick mid-week update QS shipped the kit incredibly quick, from pick up to delivery was 3 days and 5 days from order Naturally and I suppose unsurprisingly the batteries haven't arrived yet but I am under the impression that LiFePO4 batteries are safer so maybe they still ship via Air? Still...

    I believe clay is used to get a smooth surface, after gelcoat etc.. I don't think any wet sanding is necc. for a very smooth topcoat Also random question but are you using jackshafts on both of your bikes?

    Ok both of those comments are very knowledgeable So if I understand it correctly continuous amps ~cruising current whereas peak amps is ~acceleration current? Certainly seems to be an important piece of gear & concept Which motor controllers are user friendly in terms of programming? I...

    This is exactly along the lines I was thinking, especially with paying for Uni. in the meantime!

    '91 Suzuki DR 250S

    hootje, bedankt! I have got a handle on most of the maths for continuous amps wh/mi but peak amperage I haven't learned yet, how would it be calculated and can it be calculated in relation to weight of the machine i.e. similar to lb/hp or kg/kw? Thanks for the insight, the em150 came with the...

    Love your part-making skills using anything that is nearby to help get fairings built! Any reason why not some type of foam? or is it the obvious that it is quicker using materials nearby? (or maybe a kink for hot glue) :lol: I'm just about to start working on some fender repair and making...

    '91 Suzuki DR 250S

    Thanks for the offer, I'll see how it goes with the frame I have, as for the transmission I may be interested in it but initially I am going to try a direct drive style setup on this bike a quick update on the frame cleaning those scotch bright style dremel pads are more amazing than I...

    Hello all! I found many of the build threads on here very helpful while planning my build, so I will pass it along and have a build and iteration journal My primary use case is a bike to scoot around campus and town when I move to Denver in the autumn of '22 and secondary use case is for...
