My 84 R build thread !!1-14-07 Updated Cosmetics!!

[atctim]

This will be my official build thread for my 1984 R. I encountered the dreaded swingarm bolt, and embraced it with passion, a 20 ton press, a die grinder, a big sledge and a sawzall. After having it tore down, I started cleaning preping and painting. I have found a gold that matches the original R swinger gold to a T!. It is Rustoleum Gold Rush Metalic. Shelly is now hired on as my painter. Her work is most excellent, and much better than any painting I have ever done. My swingarm bolt is being made at the local machine shop - more to come on that in a day or two. Here are a few pictures from my first night of painting and somewhat re-building.

Look real good Tim, love the silver! That paint on the swinger does match fairly well.

Whats the ETC-the esitmated time of completion on this rig?

[atctim]

Josh,

ETC - less than 2 weeks. I am nearly done re-doing all of the paintable parts. My rebored/honed cylinder and new piston will be in either Friday or Monday, and my new swingarm bolt I am having made will be done Friday or Monday also. Then it's just getting it all put back together and fine tuning it. I am still up in the air about the rear shock. I need to talk to Max about that.

So what's the deal with reeds? You are 2-stroke guy. It has the originals in it now - what will different reeds do for me without changine anything else - like exhaust or carb or intake??

[max]

Just go buy a set of boysen reed pedals and remove the factory metal stops. That what I did with mine. Call me on the shocker. LOL

The reeds are a cheep mod. You will notice a little gain. The reeds are like 30 bucks.

[atctim]

Max - can do on the boysen reeds. I am officially ditching the idea of running a 200X shock in it, although I am interested in talking to you about that.

Did some more work on it tonight, but nothing deserving more pics. She is coming along real good though.

Anybody know if 84 R shocks are re-buildable. I know some shocks are and some are not. Also - anybody ever order an aftermarket rear shock for an 84 from Elka or Works?

[atctim]

Just a few more pice of the R rebuild. I rebuilt the top end. It was bored 30 over - now 40 over and a new Weisco piston and rings. Say a prayer for me as this is my first ever attempt at any engine work!!!

I got my new swing-arm bolt made and installed. Nice tight fit - I replaced stock needle bearings with custom made brass bushings (greasable). I am having an issue with the rear axel (addressed in other thread).

She is looking good and it should be a worthy competitor for the 2007 Ohio Trike racing circuit. Need to get the pipe on it - install the thumb throttle (had twist - YUCK!)I still need to buy and install Boysen reeds - possibly find and install aftermarket pipe and silencer (now stock) and redo both brake systems. She's looking good so far and I have some more cosmetic ideas I am playing with in my head that will soon become reality. Opinions wanted on the color scheme.

Looking good Tim, what kind of gearing you running with those small ass mowers (which I love btw)

Im running 18 in mowers(soon to be turf tamers) with 14/43 or my 20in razrs with 13/43.

Shes looking real good, my Z looks forward to some more R's out there

[theonlyjosh]

lookin pretty nice dude paint matches quite well, keep us posted!

[atctim]

Hmmmmmmmmm..........Kintore - you got me thinking of someting I would have overlooked hadn't you mentioned it (until its first ride anyway). What gearing should I run for 18" tires? I would like to keep it's stock speed and power. LOL - it had brand new chain and sprockets on it when I got it. What do you guys recommend for racing with 18's? (mainly MX and occasional flat track racing)

[max]

T doe, I always ran stock gearing with 18's. Even when I trail rode. I love 18's. It will rev out a little quicker. But on the track, you can just keep it in 2nd and 3rd, you wont have to shift as much. Plus you get a little more power out of the upper gears. But, I dont think she will go much over 40mph.

[RacerRichie]

Sweet fooler man.....
I have a very nice 84 250r frame if anyone needs it.....

[Derrick Adams]

Tim, those air-cooled R's make tons of torque but don't rev out quite as high as the waterpumpers. I'd probably want to step up a tooth or two from stock on the front for those 18"s.

Your biggest obstical with that bike may be the suspension. Your as big as me. I would suggest an 85-86 R frontend at least. You'll have to take Casper out for some practice laps next season.

Lookin sweet! I love the air-cooled R's! Here's my old 83.

[Kintore]

Yah I reccomend going up a tooth as well. I found my 14/43 with 18's was perfect on the smith road track.

After many hours of garage work this weekend - my R project is compkete (99%) - still need to fine tune brakes and get rear shock rebuilt. Also - stil need a few decals and rear fender # plates. Here are some pictures of the finished product. Can't wait to get it out on the track - it feels real tight! I do need to re-gear a bit though - a little too slow.

Keep in mind - this was a less than 2 week build (tear down - rebuild - re-assemble)

Good thing the snow will be flying soon - this in not recommended lawn care - LOL

[Bryan Raffa]

Brake it in slow tim.. looks awsome! good job
