I am not going to post pictures, the paint is all wrong and it has to go back. The guy didn't do anything I asked and did everything wrong. Just don't get good help these days. ( I hate fighting with people, especially around doing things right.

I got the paint back this morning. Will sort and take pictures over the weekend. I think the next step is redo the swing arm bearings and I can start assembling the frame. Oh, and I get the shocks back tomorrow, I am hoping that they look mint. Will be posting a few pics this weekend.

I believe that I have all the bits and bobs for the swing arm. The thrust bearings, never seen those before, the needle rollers and the new seals for the covers.

Question time: I know that the old DID rims were problematic, particularly the front rims, prone to cracking. If I put new Excel rims on the bike, would I be doing the bike an injustice?

Here is my IT 175, as far as it is.

Is this the kick start that you are suggesting I use?

I want to keep it in my collection, but all my bikes get ridden. I don't know that it will be a full time racer though, just go and show it at the local VMX meetings.

I have a RT3 and that kick start looks to be the same as the one for the YZ.

I have a '79 IT 175 that is almost done, just having a hassle with the front wheel and waiting on a headlight on EBAY. Will get it out and take a few pics just now.

Just fetched some of the electroplating. Not too bad for parts that are 41 years old.

We found it in an old guys garage. I went with a mate to look at two IT 490's, there were no IT's just this. The guy was just grateful for the garage space.

Isn't it awesome restoring Yamaha's. Our local agent had all the swing arm parts in stock.

Just been to the engineering shop and the swingarm is now not part of the frame. All removed and no damage done. He also kindly removed the sheared bolt. Looks like this bike wants to be restored, it is fighting much.

Thanks guys, I managed the teardown quite successfully, only three issues, one sheared bolt, the front engine mount bolt frozen and the swingarm bolt frozen. I have taken the frame in to see if we can get the swingarm bolt pressed out gently, before I start cutting anything, although I think cutting may be inevitable.

Here are a few more pics of the bike stripped.

bucket of bits, I am quite happy that the old fibreglass is still good, if a bit dry.



front forks - definitely a spot of new chrome needed here.



Bare frame with it's swingarm bolt.




And of course the rear shock - my suspension guy is going to get excited when he sees this - he got really excited when he saw the 79 IT175 back shock.

Hi, I am new to the forum. I have a YZ 250B that I am looking at restoring. I hope that I can help and get help from you guys.

Here is the bike as we loaded it on Saturday evening.






I have done a bit, but will post more pictures as I progress along.
