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.

Use the kick starter from the DT2MX it swings out unlike the dt or rt ones , stronger than the YZ one too .

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

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?

If it's going to be a show queen and not ridden I would use did rims .
If it's a racer and show bike I would go with excel rims for safety and peice of mind just my opinion.

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.

Lovely job so far Steve , The YZ a and b are in my eyes the best of the YZ's . I'm in the process of a B 250 as well started with just a bare frame and empty engine cases . http://s63.photobucket.com/user/iain_cameron1/media/085_zps8eee8350.jpg.html 
I have got a fair bit more done now . Found a airbox and covers on US Evilbay . Tony had a cylinder at Broardford bonanza , even had a head in my stash that I had forgotten about . http://s63.photobucket.com/user/iain_cameron1/media/IMG_20141103_184858_zpskopqfkhk.jpg.html

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 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. :o( I hate fighting with people, especially around doing things right.
