Well i've got my pocket rocket - a b1 rep? the air cooled chinese ones
it's running reasonably reliably....
the rest of the uni bike club is slowly growing our "fleet".....
but apart from car parks, we've nowhere properly to race! i had a website for a lot of mt wellington stuff and rules but my pc had some "Issues" and lost it
other questions:
can i get an 'aftermarket' carby and still conform to the rules? the stock one (and fuel/air filter) is so poorly built and so frequently a problem i'm getting fed up with it
what needs to be covered with nylon to protect the track - i've already made nylon pegs and the stand is going to get cut off next time it breaks but do i need to make caps for the axle nuts?
the plastic intake manifold/reed block is so soft the bolts 'sink' into it and i'm pretty sure i have an air leak around there - any solutions? washers only slowed the problem and if i do the bolts any looser they rattle out
how many hours until the top/bottom end needs rebuilding? i've done a fair few on it but never had a proper power band like my mate's identical machine has had since out of the box - also how thin can the base gasket go? i've got fairly thin gasket paper and think a bit moar compression might help;)
my front end has made a noise since i got it - frequency matches speed, does it while off the ground if you hold it right but otherwise only while riding: what size are the front bearings, or is this possibly a brake disc issue
and solutions to the front brakes: they are a little less effective than i'd like and the cable just stretches and stretches
edit: also, i've found the pull cord from an old stihl chainsaw to be pretty good along with not pulling the thing right out and finding the fault rather than pulling for hours on end, but is there a better way or cord to start the bike? it has snapped once since installing it and that always ruins the day
