Title: 1982 PE175
Post by: Coop on December 20, 2013, 05:52:09 PM
I have wanted another project for a couple years, but being busy in school I didn't have time. Last night I drug this 1982 PE175 home. Today I reduced it to the frame and baggies of labeled parts. I am going to do as close to an original restore as I can.

I plan to get into the engine tomorrow. My arm gave out by the time I had it basically down to the frame. Some clown welded the shifter on so that's going to be a pain in the butt. Some people shouldn't be allowed to work on motorcycles.

This will be a slow, long term project. I will update with any new pics or progress.

Cool project coop.
Check out my RM rebuild for peg replacement.
Be good to see the old girl back to it's former glory.

A found out last night a friend has access to powder coating and all it will cost me is materials. So the frame and any small parts like brake lever are going to get powder. I planned to paint that stuff to keep costs down but not now.

Kiwi your RM post is what really ignited my project bike fire again. I was re-reading it the other week. I haven't done one in 3 years or so. I'm ready.

Those full floater rear ends are supposed to be the bomb, looking forward to the rebuild AND a ride report.
175 is just about the perfect engine size IMHO.

Air tools are your friend. I ground the weld down and it came off fairly easily.

Ahhh I see. I was assuming it was a decent weld that might of had some penetration and really made it a pain. One less head ache for ya though. Good luck with the build!

LOL. I've never done much powder coating on my bike projects due to cost. But I can't turn this down.

cnrcpla it did. The shaft is ruined. But I needed the shifter off to get that side case off.

I tore into the engine yesterday and stripped the frame completely so I can get it ready to blast then powder.

The piston is cracked, and shows signs of significant wear. Oddly the cylinder is about perfect. All the bearings spin smoothly and are tight. There is zero up/down play in the big end and no play in the crank bearings. I plan to split the cases and change them all since I don't know how long they have been in there, but I am surprised with how tight they all are. The bike has a 1.5mm overbore; I was hoping for stock size but figured my chances were slim on that. Doesn't look like any of the cylinder companies have anything for it. My original thought was have Millennium, or similar company, return it to stock bore but nobody even makes a sleeve for it that I can find so my options here are limited.

So have you had the oppertunity to ride it before the tear down? I once owned a 1981 PE175. At the time I had it it was the fastest bike I have ever rode. Before my CR500's came along. :D.  I had a local shop bore and hone it the next size over. Plus replace the mains and seals. Saddly while I was breaking it in. The rod lower bearing seized. I never got it running again. :(

that brings back some memories , guy was out riding with us on one of those and the engine blew we had to tow him all the way back to our farm . when we got back the guy left in a car to go and get his pick up to take it home as he had ridden to my place , it was leaning against the tree beside were out digger was parked , we could not help ourselves so we dug a hole with the digger and buried it , covered it over a made up a cross .
he was not happy thought we were joking until he dug down and found a grip :-}}

we thought it was funny  ;D ;D ;D

Post by: Coop on December 27, 2013, 03:23:59 PM
I have ridden PE175's before. However I did not ride this one, I started it, bought it, brought it home, and proceeded to tear it apart :) .

Shanes though that is funny, that's a little extreme for a joke lol.

I bought a stock sized cylinder on eBay. Even if it needs bored first over to clean it up I like the idea of not being near the limit like the current cylinder is.

The overall plan is to rebuild the crank (I'll have to send it out), new top end, replace every bearing and seal in the engine, replace all the chassis bearings (the ones I can still get anyway), replace the brakes, the fork seals, fork boots, plastic, seat cover, tires, etc. That will put the total at around $1200-1300 including what I paid for it, but it will basically be like new again. Hopefully I will have it complete by April/May at the latest. I think the frame will be powder coated in a couple of weeks when I get time to clean it up and drop it off.

I have a cylinder and piston from that exact same year bike I am selling on eBay. It is pretty much a fresh bore, 040 oversize (1mm). Actually, I have the bottom end for sale, as well as some of the chassis parts. I could take it off the auction if you want it.
Title: 1982 PE175
Post by: Coop on January 02, 2014, 01:48:36 PM
I actually just bought a stock sized cylinder yesterday. I had your cylinder and piston in my watch list in case I couldn't find a stock one. If this one falls through like the first cylinder I bought and the seller claimed to have lost before shipping, I'll be in touch.
Title: 1982 PE175
Post by: Coop on January 03, 2014, 08:33:55 PM
Only updates I have is I ordered some parts. I am trying again with another eBay stock cylinder, supposed to have shipped yesterday. I ordered the oil seals, dust seals, new fork boots, etc., to rebuild the forks. Figured I'd knock something easy and relatively cheap off the list to feel like I am getting the project started finally.

I was also in touch with a few places about having the crank rebuilt. $169 seems to be the going rate and that includes a new rod kit and shipping back to me. Not too bad. I don't think the current lower rod or crank bearings are bad but I think I might just change all the bearings and seals while the engine is out and apart rather than do it again in a few months or next winter.
Title: 1982 PE175
Post by: TMKIWI on January 04, 2014, 06:07:23 AM
I always change out the lower bearings in old bikes at the start. Least you know the condition and as you said pointless doing it a few months later if something is not right.
Title: 1982 PE175
Post by: Coop on March 13, 2014, 02:40:28 PM
I have not done much the last couple months with this bike. I was traveling a lot for work and just haven't had any free time. I hope to get back to it soon. I had lined up a source to get the frame powder coated at cost but the guy is moving to Boston so it looks I missed that opportunity lol.

Cool. First order of business,  toss the toothpick pegs.

That would be a good meme.  Starts out with a picture of a bike in 1975 with small pegs.   Then says 1995 a bike with large pegs and then says 2025 with a bike with a full stair case on the side as the peg with the label "Cry Babies" :)

Finally got to do something on this bike. Only took 2.5 months but my seat cover finally came today so I got it put it on (that's a seam near the front not a wrinkle by the way lol).

I have been so busy with work and working on our house I have not done anything to this bike.

I am finally going to start back on it soon. The stock cylinder I bought is scratched so I need to get it bored. Finding someone local to do it has proven a little difficult. I may have to send it out.

This house has been neglected since my first back surgery and it is sad shape between two back surgeries, a bicep surgery and being in school 4+ years. It is taking a lot of work and money to get it back to not being embarrassed to let anybody come over LOL.

I still am going to try to get things done as I can. I ordering a piston kit soon so I can send the cylinder to be bored. I also tried to rebuild the forks (I have all the parts to do the job) and I couldn't get the caps out. I fear I may strip them before they come out.
Title: 1982 PE175

Title: 1982 PE175
Post by: blbiker56 on June 22, 2014, 04:36:06 AM
I had trouble getting my 1986 rm125 caps off, so i mounted them back into the triple clamps and used an impact gun on low psi. I did the low psi because the caps are aluminum. Maybe give that a shot, and if you use the right socket you shouldnt strip anything out.

Iv'e done that before but you relly need a single hex socket as the multi hex sockets tend to round off the aluminium cap.

remember heat is your friend...  recently I started to use a heat gun instead of a torch...  you'd be surprised how hot you can get it with a heat gun.

The heat gun was my next step. Hopefully soon I can find time to have a few hours working on it. I need the garage therapy :) .

Sorry for lack of updates. I haven't had a chance to tackle those forks yet. I am thinking this Friday is the day. Things slowed down at work finally and I am back to working 4-10's so I'll have some time again.
Title: 1982 PE175
Post by: Coop on July 31, 2014, 05:22:18 PM
Heat was a fail LOL. Those things are really stuck. Next step is the impact but I have to make sure I have a socket that will fit properly.
Title: 1982 PE175
Post by: citabjockey on July 31, 2014, 07:11:55 PM
Doesn't aluminum expand faster than steal with temperature?
If so then heat on the caps will make them tighter not looser.  Maybe try ice.
Title: 1982 PE175

I did try heating the tubes not the caps. But regardless it didn't work lol.

Heat and shrink.
Heat the caps then dunk them in cold water.
Have done it many times with stuck outboard motor parts.

Post by: Coop on March 21, 2017, 09:25:45 PM
So I am embarrassed to admit I never really did anything more with this bike other than what I last posted. I never even got those forks apart to change the seals. Never in my 38 years of riding and wrenching have I encountered such stubborn fork caps lol.

I am hoping to get back on it now that we are finally getting settled here in TX. I am looking for a place to get the cylinder bored. I am also searching for a local powder coater to do the frame for me. I need to send the crank off too, no sense in doing all this work with everything being fresh. It will still be a slow process but I wanted to bring this back to the top so I could use it to try to keep myself on track with this bike.

If you can't find a local guy I know a guy here in Washington state that can do both the bore and the crank.

Unfortunately you are going to miss out on the free stories that go with all the jobs but he does great work.

That's awesome. I haven't had much luck yet finding anybody local so I will be in touch. I was going to send the crank to "Mr Crankshaft" because last time we talked he said he had the rod and bearing kit. But I'd rather just send them both to one place.

Post by: Coop on May 11, 2017, 05:58:20 PM
I've been having some serious back issues and may be facing surgery #3 so this is back on hold for now. I am trying to find a local place that I think will powder coat the frame for me. That is something I may be able to pull off right now. I also found all the plastic on eBay so I hope to pick it up soon. Finding an OEM silencer in good condition has been tough/impossible, mine is trashed. A place in the UK sells an aftermarket silencer (DEP brand) I may end up buying. It's the only place I found them in stock anyway.
Title: Re: 1982 PE175
Post by: rsmith on May 30, 2017, 06:30:51 PM
Thought on the frame.

On my 81 YZ restore I considered having it powder coated but after much back and forth and some input from guys in the vintage community I decided to have it blasted and painted instead.

The reasoning was that if you intend to ride it whatever you use is going to get worn off above the pegs and you can touch up the paint and it will look good, but you are kind of stuck with powder coating.

Title: Re: 1982 PE175
Post by: Coop on June 06, 2017, 05:49:20 AM
Yeah I have considered that. I always use either clear vinyl or skateboard grip tape on frames for protection. I have rattle canned a couple restorations trying to be cheap and it looked like crap in no time. I can spray it with auto paint (I have that equipment already) but then you still have to be cautious how you touch it up so you don't use incompatible paint or if you respray it takes careful prep work so you don't spray everything else lol. Powder holds up very well because it is approximately twice as thick as paint. I haven't decided but I see pros and cons with either media.

Post by: Coop on October 08, 2018, 05:28:03 AM
I haven't updated this in awhile because my surgery last year now my illness has preventing doing any work. I am considering just selling it as a project bike along with the new parts I have accumulated for it. I am on a PE group on FaceBook and a few members are from Texas that may be interested in a cheap project. I can't ship it so it would have to be a local sale. I was looking forward to seeing it finished but I might be over it. I am not 100% decided yet what I am going to do.
Title: Re: 1982 PE175

Sad day, I sold this PE project today. A local guy offered me $400 and it is a basket case at this point. Plus that was $300 more than I paid for it. Medical crap is expensive and I am on unpaid sick leave. My wife says when I get my NED diagnosis next year I can buy a brand new 2T to celebrate so it was a good trade off :) .
