Turning the link pipe determines where the silencer fits in relation to the swinging arm. I found having the bottom part level with the ground made the best fit. Don't nip it up until you get the angles right.
Get spring pullers, more uses than a swiss army knife (ok maybe an exaggeration!) Fit the s section first to the o2 sensor ( twist the s section onto the sensor) this will reduce the possibility of damage to the wire by over turning. Then attach to the header pipe. Copper grease the joints When lining things up watch the clearance between the o2 sensor and the rear linkage, ham fisted twisting can cause the wires to hit it and cause damage Make a modified baffle bolt, I'll try to get pictures but this is essentially a long allen bolt. ( or lose the baffle all together!!) Watch them grommets! Easily lost in the sleeve.
as Mr OCD said in another thread the r77 runs nicer with a richer map than stock, a full power map is quite juicey on fuel. Without the baffle idle can be lumpy (1000 - 1400 rpm), ECU can have a spaz controlling the rev at idle, but I run open loop fueling and the bike is just oh so silky!! I run a commuter map, economy in the cruising areas and full juice when i need the full beans!
Now I'm lost not to clued up when it comes to remapping etc as for the open loop fueling haven't a clue mate
I probably got the naming convention wrong! could be closed loop!. In any case I have a custom map for the yoshi, but in addition I also have a wideband sensor that continuously adjusts the AFR for economy, the base map is full power but obviously a bit more thirsty. As others have suggested the yoshi can run a little lean on the stock map, some people dont notice but others feel this as a snatchy throttle and maybe a lumpy idle. Mine is silky smooth, howls on the throttle with a lovely rumble/pop on the overrun.
