    Clamp swap w/hpsd?

    So none of you guys have tried this? Or has it been beat to death on here so much that everyone figures I will get the hint and search it. I have tried the search but haven't found anything that has answered my question yet! Anyway, have a nice turkey day everyone. Thank you. John.

    Clamp swap w/hpsd?

    Does anyone know? If I swap my '09 crf450 clamps to my '09 crf250, will the hpsd mount up w/o requiring further mods to the clamp or the bike itself? Thank you for your help and time. John.

    crf clamp swap.

    Hello, I have a set of kyb forks with triple clamps off an 09 crf450. I am wanting to put them on my 09 crf250. Now I understand that the bearings need to be swapped and a few shims need to be added, my question is Once I have changed bearings and shim'd will the HPSD still mount up w/o further modifications to the bike or clamp? I appreciate all your time, you all have a good nite. Thank you. John.

    450 ate alot of dust.

    Thanks for the replies guy's. Greyracer, I see alot of good sound advice given by you throughout this site . I am sure everyone appreciates it, I know I do. So like I said, this thing ate alot of dust. After asking many questions, I found out that a fella at the track offered to quickly clean the filter on site. So to make a long story short this guy took the bike and brought it back with a cleaned filter. But now I know the guy used gas to strip the filter of any oil, then never put any filter oil on it. Nice guy, very helpful. So I can see the valves, they look almost to clean no carbon build up. And their is a very hard ceramic build up on the valve, where the rod portion connects to the valve. Is this normal. It looks like the heat from the valve body melted the dirt to a semi-liquid. All I can describe it as a ceramic blob. Kinda curious what you think of this, and if it changes anything as far as a rebuild or not. Sorry so vague on the description, hope it made since. John.
  6. A buddy of mine brought his 09 yz 450 over to my place. He said it would hardly run, and backfired alot when it did. I told him I would give it a look and just figured it had a gummed up jet because of sitting to much. I pulled the seat to check the air filter and almost fell over, the filter had passed alot of dirt. The cage was coated with it, the intake was also coated. Digging deeper I realised the dirt had plugged the jets in the carb so bad the bike wouldnt run. So I am just a hobby mechanic and need some advice from people that deal with this stuff for a living. So the bike has not broke yet, how risky would it be to tear it all down removing as much dirt as possible, put it back together and ride the thing? I would like to avoid a catastrophic engine failure. Would a rebuilt head, piston and ring be a better move? With that much dirt should I be concerned about a bottom end failure in the future. Advice will be appreciated. Ough ya, 1 more thing this bike looks almost new from the outside and if I had to make a guess it has about 10 hours on it. Thank you for your time. John.
