I contacted 2 of my friends, (they have the same type of bike) and both of them have the same problem, but they don't believe it is caused by wear and tear, they believe that when the front suspension suffers a big impact (like wheelies) it fails, I know this bike isn't yamaha's best work, but if the suspension cant take anything I don't have any use for it. Any thoughts? Could the suspension just be crap or is it a factory error? (assuming the failure is caused by impact). Anyway I'll bring the bike into the workshop on Tuesday.

Both of my front fork seals have failed (apparently), both seals seem to be leaking oil at an alarming rate, the thing is, this happened at about 3000 km, and it seems to have happened to all the models of the same year, I cant replace the seals myself since the dealer can't find me a repair manual therefor I have none of the information i need to replace them myself. The problem is they want to charge me 250$ to replace them, but it seems like a factory error, If its happening to every bike under 3000 km it cant just be wear and tear. Any thoughts, should I go down there and raise hell about it or should I just let it go and count my losses? If it matters the bike type is DT50R 2007, Its a enduro style moped.

I have a Yamaha DT50R 2007, I've removed most of the Restrictions but I'm still having trouble with the electronically restricted part, when I get up to 8000RPM the engine starts choking, a friend of mine has fixed his bike (he has the same model) so I know this is possible. (Someone did it for him so he cant tell me). I'm pretty sure the unit is called a CDI. Any ideas? Don't tell me to buy a larger bike, I'm only 15 so this is the best I can get, (Legally that is, or sort of ) I've changed the sprocket to get more speed out of it, but I'd still love to get rid of the electronic restriction. While I'm at it, can someone confirm the size of jet I should use after it is De-Restricted, I was told 94-96 (switched from 80) so thats what I'm using, is it the correct size? Thanks.
