Case Work on Viragos

Have It Done Right

This one makes me a little nervous as it involves the back-and-forth shipping of empty cases: bulky and fragile. Be sure to empty all fittings and just send in the basre aluminum with the cast-in iron parts. Bolt them securely together. Lay multiple layers of bubble wrap around them. Fill with styrofoam "peanuts" or expanding foam. Anything that must be removed or scraped off on our end will incur more costs to you -- if you expect to get them back.

What we'll do:

Chemical dip (unless you ask us to skip it) to strip all grease and dirt. Blasting with several grades of beads, ending with walnut shells. All oil passages will be blocked at this stage. Optionally, we'll powder-coat black or silver inside; your choice outside. Your main bearing bores will be hard chromed down to 90mm ID and the 6308 bearings of your choice will be seated. Bearings that have oiling channels and oil holes could have passages bored into the transmission feed lines in order to make sure that there is no starvation problems as stock these bearings are fed by splash. Case spigots bored to appropriate girth for your application. We'll look into a maximum bore cut with snug-fit aluminum rings for smaller sizes included. All potential obstacles to long stroke cranks will be fly cut off; all iffy protrusions. New dowels for oil passages and a plugged tap hole for those that want to run an oil cooler from near the pressure release, rather than off the filter cover.

That's all that comes to mind at the moment. No prices set. Reckon on $65 each way on shipping. I must get quotes on plating and powder coating and prices on various bearings. All of these procedures take place elsewhere. Before you ask, do NOT ship complete engines for us to build. This location is not zoned for it. And we can't afford to farm it out. Shipping and transportation add up and no matter how good of friends we are with third parties, they won't work for free.

1 1 1

I realize that one can simply buy used parts of salvage bikes for pennies on the dollar. Thus, Iwe won't try to sell large pieces of running gear, like swing arms, forks, or wheels. There are some parts that are just not right if not tailored from new. Other parts are too specific, they just don't seem right off of their original model.

Throttles

Did you consider that your new carbs require a greater "throw" than your stock throttle can give them? If you opted for Big in the piston department, you'll need to run a one-into-two cable that can fully open 38mm carbs. And if you went for Huge, you'll need a push-pull unit driving split cables that need at least 41mm. All of those below are 'quick' throttles; they don't require much of a twist to open the carb bore completely. WOT is a breeze and it makes it no chore to embarass other riders.

I realize that a lot of after-market throttles can be had for twenty dollars or less, but most of them are only able to open throttles up to 32mm. And they make a big deal of it if they can acheive fully opening a 36mm. Worse, they are all the cheapest possible plastic. The throttles below are high quality aluminum CNC machined products out of England. The quality is evident the moment you first handle them. Light and smooth, and good-looking, they'll enhance the value of your build. Pistons and cams are expensive. So is bending up custom exhausts. Don't forget adapting more modern forks, wheels, swing arms, and all the other little deails. These are a detail that radiates quality. Your bike deserves one. You deserve one.

A quick scan of eBay listings for the XM2 finds prices with shipping of $150 to $200+ and a wait for international delivery. Carb kits will optionally include a throttle from those below. Dual TM38-86 kits will include a Mostro and a one-into-two cable. Dual FCR41 kits will include an XM2 throttle and two one-into-two cables.
