Hello, I am the shop teacher for a rural high school in Oregon. We are starting to restore a 1972 175 CT2 I believe. It currently is disassembled farther than the pictures show. We are looking forward to the project and will post updates here. Check in to see how we are doing.

Today we sandblasted the tail light housing, the chain guard, and battery box. We then primed those parts. The previous owner pressed out the swing arm bushings and dented the swing arm on both sides. the students welded the dents in and ground and filed.

Welcome aboard--from NZ down under. Man secondary school was never like that when i was started there at age 13, umm, 59 years ago lol, or i'd still be going to school. Great to see kids doing this sort of thing with an enthusiastic teacher. I worked in the local Yamaha shop back when these were new so know them well but then again so do a lot of folk on this site. Some of the restoration on here leave me head scratching as are better than new some of them, plus i'm just to damn lazy to get into restoring. Be careful with this model as kick back pretty hard so i'd be setting the timing on the fractionally retarded side, like points at 12thou instead of 15thou. We had a heavy flywheel brass ring we fitted to any of these that we sold to farmers to make easier to start & also made them into a lazy but still powerful motor --if that makes sense!!. Had our "big brute" farmers kicking them so hard that things would break in the kick mechanism. the first model CT1 piston port motor of 1970/71 had a heavier mag flywheel combined with a softer ported motor before reed valve & was great. in saying that--these are great but in a bit of a racehorse way compared to a Clydesdale CT1. Jeez i talk rubbish. Hope i've not put ya off. Cheers.

Thanks for the input RT325, That is what we are looking for...Advice and info are always welcome. Hope we can do this justice. Hopefully can do a little to it each day. The frame will be blasted next and then install the swing arm and bushings.

Nice to hear about some areas still have High School automotive or mechanical shop. The only classes that mentally got me through HS was Auto Shop. Nice to see another CT2 getting the business on Y-E.com!

Re the bushes, not a problem but the original swing arm bushes never really wear out & any play is usually the swing arm bolt has been left loose or not tightened when needed & play is on the bolt. But main point is being rubber stretchy bushes--whatever ya call them--it pays to tighten them in the neutral position with them connected to the shocks as they would have a limited range of movement if say you tightened the bolt with the arm hanging down then pulled it up against rubber tension to connect to the shocks, then having to travel further with the shocks--could damage them if going beyond the stretch limit.

If blasting leaves pit-marks a wire wheel on a grinding motor is a good alternative.

A drill - wire wheel will take a rusted exhaust to where it needs to be.
