I thought I'd finally do a build thread. I was planning on doing one several years ago when I initially put a 10T Mac with a 9 Fet controller on my 2001 Kona Stab. But in the end, I never did - I thought it was pretty cool, but it was a little bit too run of the mill to hold much interest for others. That cannot be said for the LR kit! All I can say is that it was like Christmas when it finally arrived a week ago after nine months of waiting . The build quality appears excellent and you can see all the attention to detail and effort Mike has obviously put in. Little things like plates for his adjustment screws to push against, flush mount screws, those carriage bolts and the list goes on.
Anyway, the kit came well packed via USPS/Canada post. No issues:

I received the full 219 kit with chain breaker. I did elect for a 75T 219 sprocket as I was worried about clearance with the swingarm.
I got two chainrings, a 48 & 34T. I was expecting a 44T bike chainring because I had read one of Skyungjae's posts about clearance issues but the 48T actually turned out to be a good thing as it ended up fitting after dealing with some spacing issues and I like the idea of a little more top end as I have a low gear to drop into if I want more torque. The 48T is pretty much exactly the same size as the bash guard for the 75T.
I spent Canada Day installing the kit. The plates fit my 68 mm bottom bracket perfectly. I needed to grind a bit off one side because the Stab/Stinky frame as very little clearance on one side. I also found some minor issues with the spacing of the bottom bracket - it was a little tight on the chain side so I needed to space it over by 10 mm with a couple of spacers from old ISIS BBs bracket I had laying around. That pushed the whole assembly out such that I have a millimeter or two clearance between the large chainring and the swingarm and also the bolts on the kit. I also had to remove a washer on one motor bolt because the chain touched when chainging gears.
I spent a bit of time figuring out how to get the belt tightened properly. It is a good idea to make sure the adjuster bolts are nicely tightened before you put the pulley on. I ended up using feeler gauges wedged between the nut and the sheets to hold the bolt in place when tightening the nuts as there is no room for a wrench. This technique worked to tighten the locknuts too.
I found it a but tricky at first to square the jackshaft when tightening the belt and ended up with a situation where the belt wanted to walk off the pulley. I ended up putting a strap around the 219 driver and using a screwdriver to lever the assembly back towards the motor and then snugged the plate bolts. But I'm sure that this kit makes it a breeze compared to what it must be like with the GNG kit. Not really sure how much tension to put on the belt.
I did a bench test of the motor with my EM3Ev controller. I used Lyen's website as a reference to get the colors to match as he listed Mac and GNG setups.
If anyone else is interested, these are the color matches for both the halls and phases:

The motor worked fine. It drew 85 Watts with no belt on at 45V on my CA V3. After putting the belt on, it was about 115. It is slightly noisier than the Mac, but definitely not loud. I have yet to determine how noisy it will be with chains because I have yet to install the chain. Mike ordered a bunch of 34 inch chains but for some reason, I guess he received a 30 incher in the mix and that is what I got. Not quite long enough. Mike was fantastic to deal with even though he seemed a bit disappointed that it wasn't perfect. I haven't got to try it yet, but it seems pretty close to perfect to me - especially compared to my otherwise ghetto build. Anyway, he sent out some extra links same day so hopefully I'll get them sometime this week.
I had this weekend to play around a bit so I added a mudguard for the belt. Mikes safety brackets make adding such a thing a snap. Basically just cut up an old plastic downtube fender and used a paper hole punch to allow the screws to hold it in place. If Mike makes a mudguard, I'll probably order one, but in the meantime this should do the trick. Also threw on a new headset and ordered some Shimano SLX brakes. The old Hayes HFX 9s are a little long in the tooth and I have replaced pretty much everything else on the bike.
Hope to be up and riding very soon. I ordered a GPS analogger from Ebikes.ca so I can upload trip data to Justin's cool new trip website. At some point I'll get a temp sensor in there to add that into the stats. There are some fantastic mountain trails around here so I should be able to put the kit through its paces!
