the spare tyre is still good and now has a good 2 hours hard use on it
i guess we've managed to get a good use out of those rockets. two of those tyres were showing fibres after me and jafa last rode them.
so i think we should really discuss where we're going with these. if it's worth putting tyres on, that means we plan to continue the cycle of fix-ride-fix-ride-fix (admittedly i think the fix part is getting acceptably short compared to the ride part, but whenever i say that a pullstart breaks), but as soon as we spend money on anything other than petrol, it kinda seems prudent to have me make up some more nylon pegs.... and once that's done i reckon an instant fix to 95% of our fuel leak and reliability problems would be to buy some carbs.
then we may as well slap on a big bore kit etc etc and before you know it you may as well have bought a bucket bike
although, with the latest f3 developments in the club, just buying the carbs could be acceptable. just for munting around carparks etc
yeah.... i just can't bear to spend money on them, especially cause once i start i'll buy the best bits and keep on doing so. then again being broke will help fix that
$35 tyres plus fitting
$35 carby that looks too much like the stock one simply bored out
$55 flatside carby with billet manifold and pod filter
so basically i'd say $100 per rocket to get them reliable. this is half of the price of a new one, and may not fix the underlying problems which seem to centre around fuel delivery to the carby bowls which could be in the carby or in the tank. they will have moar power though....
i would love to experiment further, but with only one tyre it becomes a bit tedious. it seems at their peak the motor will last about 8-10 minutes of my circut (in video above) before they start cutting out at open throttle. idle or half throttle a bit and she comes right for a few more minutes, i can only assume as the bowls fill back up. this could be for any reason, including low head pressure from the tank as it gets around half empty, but this could be fixed with a better built carby with assumedly better valving
there are leaks that magically appear despite the fuel being turned off. one insists on dumping fuel out the overflow for some reason, but runs fine and doesn't leak so much while riding
oh, and fairings are very good at catching bolts as they rattle loose
edit: and without hitting the track quite yet, i think gearing these down (add a tooth or two to the rear) could be a good idea. the red one is slow but with a mean power band, but you only ever hit the power on an entry to a corner
