Hello.. Nice forums, just got myself a second hand 1998 wr400f, needs some tidying, but is ok in general. I've read through the posts, some great info there, thanks to those who contribute. I'm just riding the bike to work out what needs sorting, gonna pull her apart next week. Re the YZ timing, are there any drawbacks to doing this ? as I want the power increase, but do use the bike to plod about by road to the various dirt tracks/beaches and dont want to sacrifice road rideability/reliability for a bit of extra power.. The bikes allready got a comp exhaust and from the posts I've read I reckon a previous owner has removed completely the throttle restrictor pin, hence I get a pop and bang, hesitation occuring mainly on the road accelerating using full throttle. The misses start to occur about mid way thru accelerating and decreasing the throttle seems to smooth this out.. maybe its another problem ? (havent taken a spanner to her yet, so maybe the plug needs replacing) Although its got comp exhaust, the airbox lid looks to be intact, so i'll give removing that a go. Havent stripped the carb yet, but I expect it to have standard jets. More on that once I know what its got now I guess.. Whats the Gray wire thing I've read mentioned, is that a wr450 thing ? If anyone wants to give me a basic starting point check list I would be most gratefull.. I noticed the archived forums arent accesible, shame cos there is some posts in there I think I need to read.. Conditions here in Portugal are dry and dusty mainly, just above sea level as I'm by the coast, temps usually around 25 - 30c..
