switching out the swingarm

[Jon_P]

so i just cant leave well enough alone i know. and now i am at it again.

just picked up a 80's r100 swingarm with drive shaft. its a little over a inch longer than the one i have and almost two inches longer than the other. so i dont remember which one came with the bike but the must be close to a swb swingarm?

has anyone else switched swingarms?

and has anyone rode a earles type front end? what are the pro's and cons?

Nice to see you still around Jon.

The R100 swing arm will be longer than the R65.  If you swap you will take some of the 'agility' of the short wheel base R65 away.  You will also need new shocks....assuming you have a standard frame.....Knowing you we cannot make that assumption

My /2 has an Earles fork - biggest difference is that the front end doesn't dive when you use the front brake. In fact the geometry is such that the front end will RISE under very heavy front braking. (If you can imagine the original drum brake capable of very heavy front braking) Of cours it is heavier and may be a bit slower to turn. the advantage with my sidecar rig is that the trail can be lessened to provide faster steering.

hey steve, and you would be right on assuming my frame wont be a stock frame.  

i have been working on it the last couple nights and in fact started working out how i can make it look like that 34 r7 they dug out of the back of the ware house a couple years back. also toyed with the idea of making it into a plunger rear style. anyways i am after a older look for it for sure.

Hey Jon, that girl has a nice set of opposed knockers eh......and they are real!

[Jon_P]

kind of shooting for something like this.





i wont as crazy as this. there are alot of things i like but also dont. i dont see the need to change out the carbs and there are things on the frame that i am changing.

then again i like this one alot also.

I do like your style, Jon!  8-)

Do you reckon you could figure out a way to add floorboards and convert to a suicide shift?  Always did like that green/white bobber from the first time I saw it.

[Jon_P]

floor boards should be that hard. the hand shift is something i am not interested in doing. i should be able to come up with a plan for one but i never got into the whole hand shift thing.

what i really wish i could see is how guys hang the engines from the frame and remove the lower frame rails. i have been searching the net for pixs to see how guys are doing it but no one is showing any detailed pixs of that. that is the one cool thing they did with that r7. that prototype was years ahead of its time and yet they waited to do alot of those changes later on.

for those wondering why the longer swingarm? to stretch out the bike in the rear so i dont have to go through the work on making a longer drive line. i can, i in fact have all the tools at work to make a drive shaft longer and balance it. i just like the idea of not having to do that. plus i can keep it in the tube and keep it oiled.

THat R7 is beautiful!

Looks like a turbo on the bobber?  Cool.  How about a pic of the BSA?
