I I like 4 into 2 but only for symmetry. 4 into 1 seems like the choice for a lot of people

4:1 is the most popular for "cafe" style of bikes. They are also the most sporty looking. Best and most popular brands are:
MotoGP Werks (throaty, somewhat loud, best performance, my favorite)
Ripple Rock Racers (sells a Handle brand, good quality, Canadian exchange rate in your favor)
Delkevic (bought via eBay, least expensive, but still decent, may have some mounting configuration changes required)

All these require abandoning the center stand. All are Stainless.

I still can't believe that i did this.  I'm completely responsible.  Its a long sorted story and im sure I'll need therapy as a result. But this 17 years of gunk built up in the carbs and the gas tank is worse.  4 cans of carb cleaner and a lot of brushing.  I'm starting to come down now from the buzz now.  I promise I'll never do this again.



They look better now.  Everything moves pretty smooth.

Send them to Nils (restocycle.com) and they will look better than they did when they were new.

Ant thought on how this would work for a motor or work stand?  Was thinking it would fit on a standard motor stand that I have already.

I'm open to suggestions

Thanks

You will have to trim the angle iron down to fit around the output shaft and seal area. The other side may need trimming to not interfere with the clutch cover. Someone on here put a stopper at the top also to allow inverting the engine and removal of the bottom case half.

As long as you have ample clearance between the rods and the mounting plate, you'll be fine.

Ok... great!  Its simple.  I can whip this up in no time and get this motor off the small bike lift and on the stand were I can get all around it.   Baby steps.   Thanks for the help and support as always.  And I thought YouTube was the best source if info.   What was I thinking?

Thanks guys

Some triangular braces from engine post to casters really helps make those stands a lot more rigid.

And the other direction. Make sure the first you drew allows motor to rotate 180*

Yes I'm going for the frame kit.  Im just kind of screwing around fitting things and see how they look.  I actually put the tires and rims on too. But i took them off and removed the tires. Im going to pick some new sneekers out shortly.   I wanted to see about seat hight and position of the rear controls and general geometry of me sitting on it.  I don't really know about the rear vontrols and the clip ons.  I dont know how comfortable its going to be.  I sent the rims to my son for blasting and powder coating.  The front shocks are coming back off too.  The uppers are rusted so bad i didn't put the new seals in and no oil in the shocks.  I guess i need to visualize a little bit.   I even put the rusty rear shocks on.  Playing with seat position.  Playing with a design of the oil tank and its position. 

Its likeva puzzle and i kind of enjoy it.

happy to be here... even if I have no clue whats going on!

Anyone got thoughts on rear spring replacement?  What's popular?  Benefits for longer springs or shorter ones?  My stock size is 13 3/16.

Anyone have suggestion about the rods that hold the rear of the motor in place?  I'm going the make a bracket that hold the rearsets in place. But these long bolts or rods are too long.  What do builders do?

They're long to accommodate the old very thick plates that held the foot pegs and rear passenger pegs.

  The only thing i can think of is put more threads on there and cut the excess off. Or... have new ones made.

Any thoughts?  They will be appreciated.

John

Most people either have the bolt shortened and turned with new threads OR source (or make) a new bolt.

Any ideas on the grade of steel?  Hard I would think.  Cut the threads before the Harding process I would guess?  I need a machinist.
