Hey again everyone. After a lot of frustration with getting stuck on little things that anyone with some bicycle knowledge probably would have avoided, I have finally completed my build!
It goes to show that someone with absolutely no bicycle knowledge can build a motored bike with a SBP shift kit with a little help from the internet, bike shops and SBP.
Today I took it for its first lenthy ride of about 15kms through some very hilly areas and it didnt miss a beat. The fresh engine doesnt rev very well at this stage and riding the bike with its 9 speeds is akin to driving a truck. Using the gearing and not much throttle it gets up hills and up to speed along the flats without too much hassle.
At this stage the only minor problems I am having with it are that the carby leaks fuel all the time, the bottom bracket seems to come slightly loose all the time and the engine doesnt seem to rev much kind of like it runs smooth under certain conditions then misses at other times though Im not sure if this is just the way a 2 stroke is.
Anyway here are some pics.
Sadly I didnt get many pics of the build process as my camera was flat and I couldnt find the charger. It was a reasonably straight forward process although I did have to modify a lot of things and fabricate a front engine mount. My dremel rotary tool proved to be an invaluable aid in my build.
Stupid things I got stuck on were
-Bottom bracket. With no clue on bikes I had no idea of the difference between my hollowtech octalink cranks and the cup and axel type required for the build. This meant I went from my octalink, to a sealed bearing setup before I realised something was not right and emailed SBP who promptly informed me about needing a cup and axel setup.
-Getting the 415 chain shortened. Neither bicycle shops nor motorbike shops wanted to deal with this chain. I ended up getting it the right length but broke my chain breaker in the process.
-Fitting a cable to the 9spd grip shifter. For some reason I just couldnt get the ******* to go in. So I got i had it fitted at a bike shop who cut the cable too short. I then had to go back and have another fitted.
-The cable that came with the clutch was too short and I fitted it incorrectly the first time around adding to the WTF? factor.
-I initially couldnt get the bike to pedal smoothly but after some advice from SBP I modified the master link on the 415 chain and completely dissassembled and resassembled the shift kit and got it working nicely.
Thats about it. Thanks to SBP for the speedy replies and to the SA bike shops that helped me out.
