· Bar weightsBar weights can make a big improvment in vibration through the bars.  Most Virago’s do not have this problem, but if you have a vertical twin, and the handlebar vibration bothers you, you might want to try bar weights, preferably over 5.0 ounces or 142 grams each.  See the bottom of this page for examples of bar weights.

· Bulbs – replacement – The 3 watt neutral indicator bulb is number 42X-83517-00-00. LED replacement is T6.5 .  (T5 will fit but it is loose. You might could add some tape to make it fit better.)

· Carb heaters, disconnecting – Virago 250 – I disconnected mine to try it – bad idea to disconnect if your location is ever below  59 degrees F  (15° C)http://wp.me/P1LWaM-jp  (bottom of post – item #14)

· Carburetor jets for Virago 250 – The 6 Sigma jet kit for Virago 250 includes three main jets (you need just one) 115, 120, and 125 and one low jet #20.  Stock jet is 110.  Reasons to re-jet:
1). you added less restrictive exhaust — you need to run richer – get a larger jet size
2). you added less restrictive air filter — you need to run richer – get a larger jet size
3). high altititude (at high altititudes, bike will run richer)– you need to run leaner – get a smaller jet size
4). spark plug color — this is complicated, but if your plugs are black, you might need to run leaner – get a smaller jet size.
If you have questions on jets or carburetors, go to the Virago Tech website – they really know this stuff.

· Carburetor – polishing the Virago 250 carburetor  http://wp.me/P1LWaM-lj  (near top of post)

· Carburetor joint, plastic is cracked – do  I need to replace ? – Maybe not.  Check it while spraying something on it while the engine is running.  If the engine speed changes, carb joint needs to be replaced.  On my 2002 Virago 250, the carb joint is cracked, but it does not need to be replaced.

· Carrying space – Virago 250 with Rifle Sport fairing – create low cost 2,200 cubic inch space by moving headlight forward and speedo back behind the bars.  Doing this mod adds no weight to the bike.  http://wp.me/P1LWaM-jp  (middle of post – item #10)

· Center stand – adding a center stand to a Virago 250 (sidestands cause a lot more trouble than centerstands.)   http://wp.me/P1LWaM-gz

· Center stand – where can I buy one ? – Very hard to find.  Rarely on ebay. SWM makes one for Dragstar 250, but not Virago 250.  http://wp.me/P1LWaM-gz

· Chain – what size? –  A virago 250 with stock sprockets (16 front/45 rear) takes  114 links of #520 chain

· Tires for Virago 250 – list of all the sizes that will fit (some require modifications to fit) – list of actual weights of five 130/90-15 tires  http://wp.me/p1LWaM-R

· Tire Pressure for Virago 250 – the factory recommended  tire pressure is:

Up to 90 KG (198 lbs) load :

25 PSI Front / 29 PSI Rear with 130 rear tire

(approx 25F/ 26R with 140 rear tire)

Over 90 KG (198 lbs) load :

29 PSI Front / 32 PSI Rear with 130 rear tire

(approx 29F/ 29R with 140 rear tire)

· Top Speed – Virago 250 – Official top speed is always on level ground with no effect of wind.  Official top speed of the Virago 250 is 85 mph.  Going downhill with a tailwind people have gotten very close to 100 mph, but that is not “top speed”.  My own bike has 17/39 sprockets and would do 98 mph downhill (8,400 rpm) with a tailwind.  Trivia/physics – compared to a lighter rider on the same bike, a heavier rider would have a lower top speed going uphill,  the same top speed on the level (but would take longer to reach it), and a higher top speed going downhill.

· Torque settings, partial list- Virago 250  http://wp.me/p1LWaM-6l  (item #8)

Torque Settings for Virago 250 (front forks):

… cap bolts on top of fork 17 ft lb (23 Nm) … 10mm crown nuts at top of fork 22 ft lb (30 Nm)

… 10mm front fender bolts 14 ft lb (20 Nm) … pinch bolts 14 ft lb (20 Nm)

… front axle 42 ft lb (58 Nm)

Torque Settings for Virago 250 (rear):

… swing arm pivot 33 ft lbs (46 Nm) … 10mm rear shock nuts 17 ft lbs (23 Nm)

… allen rear fender to frame bolts 43 ft lbs (60 Nm)

Virago 250 exhaust torque (10mm nuts) – about 7 foot pounds
(I have never found the Virago 250 spec, so I use the spec from the Honda CM400 – header pipe torque – 7 foot pounds (range is 6 to 9 ft/lbs). The CM400 exhaust studs are 6mm (nut is 10mm).)

· Valve Adjustment – How to Adjust Valves on Virago 250   http://wp.me/P1LWaM-Cd

Adjust Virago valves every 3,000 miles – do when cold
intake .10mm (range .08mm to .12mm)
exhaust .12mm (range .10mm to .14mm)

– intake .004 inches (range .003 to .005 inches)
– exhaust .005 inches (range .004 to .006 inches)

· Vests, reflective – motorcycle safety – it is amazing – just spend $6.39 and get more respect from other drivers.  It even helps if you are an agressive driver.   http://wp.me/P1LWaM-lj  (near bottom of post)

· Vests, reflective – motorcycle safety – my first report on wearing a vest and the dramatic difference it makes   http://wp.me/P1LWaM-jp  (top of post – item #3)

· Voltage readings – what should they be for a Virago 250 ?   Examples:

12.5 volts – Headlight and 55w x 2 spots “ON” (at 60 mph)

13.4 volts – Headlight off, spots “ON”.

10.8 volts – At a fast idle (headlights and spots on), mine starts at 11.3 volts and then settles down to about 10.8 volts.

12.9 volts – Headlight + carb heaters (50w) “ON”

12.3 volts – Headlight + carb heaters (50w) + driving lights (110w) “ON”

13.2 volts – Headlight  “ON”

(My readings are low, because I wired my gauge to some small wires near the headlight. I would get higher voltage readings if I ran a larger wire directly to the battery.)

· Voltage Regulator, exposed – mod for Virago 250 – The “delete left side plastic cover and expose voltage regulator mod.”  http://wp.me/P1LWaM-mX  (bottom of post)

· Voltage Regulator, does mine run too hot? (Virago 250) – If it is hot enough to burn you (over 120° F), it is probably running too hot.  I think mine is “normal” – my Virago 250 voltage regulator runs hot but will not burn you after a 30 minute ride, so it is maybe 118° F( 47.8° C).  (My 1981 Honda CM400C runs a little cooler – it is maybe 115° F (46.1° C).)

After a 90 minute commute in hot weather, my Virago 250 voltage regulator will burn you, so it must be over 120° F (46.9° C).

If your Virago 250 voltage regulator is running too hot, a temporary way to help until you can get it checked-out is to run more lighting (such as incandescent spot lights – not LED) so the regulator will not need to absorb quite as much current.  Drilling holes in the front edge of the side cover or just leaving the side cover off might help, also.

· Weight reduction … is important for small bikes like the Virago 250.  http://wp.me/s1LWaM-test

· Whitewalls, white – You can get whitewall inserts for $30 per pair at Mooneyes.com. The width available for 15″ and 18″ is 7/8 inch or 22 mm (so they are not as wide as “gangster” whitewalls). The picture has a mock-up of these so you can see the width (they look wider up close).

· Wiring under seat – making plastic cover for wiring under Virago 250 seat  http://wp.me/P1LWaM-jp  (middle of post – item #11, also two pictures)

——————-

Bar weights – Bar weights can make a big improvment in vibration through the bars.  If you have a vertical twin, and the handlebar vibration bothers you, you might want to try bar weights, preferably over 5.0 ounces or 142 grams each.

    Hi, have you ever come across these virago’s getting oil in the frames?
    Chris

    • lstrick115 says:

      Hi Chris,
      Yes – oil in the Virago 250 frame almost always comes from the air cleaner. The stock air filter is foam, so it needs to be oiled. It you use too much oil or the wrong kind, it can go into the frame. If your air filter is in good shape, you can just clean it and re-oil it (use oil made for foam air filters). If the foam has gone bad (this is common) find the paper air filter mod on the Virago Tech.com website (post is “Air Cleaner Stuff” – http://viragotechforum.com/viewtopic.php?f=6&t=30147). This is a great mod, it is easy to do, and the element is easy to find.
      If you do keep your foam filter, make sure to use the oil made for foam air filters (not the oil for paper K&N filters – it is different). It is real sticky and stays on the foam instead of flying off like regular motor oil. I used motor oil for mine (I’m cheap) and it got on my engine and my clothes.
      Thanks for the question,
      Les S.

    can you show a correct diagram with all the hoses and pums correctly carburetor, vacum and hoses from gas tank please urgent from portugal xv 250 bobber

  3. rodrigo says:

    can anyone please tell me how to fix the speedo. it is often inaccurate, the pointer oscillates a lot, apart from getting stuck at 40 km/h and wont go down to zero.

    • lstrick115 says:

      Hi rodrigo,
      A speedo is hard to fix, but maybe your problem is the cable.
      Make sure the cable is straight and not kinked.
      Remove the inside part of the cable and grease it except for the top 75 mm or so.
      In other words, don’t get any grease on the last approx 75 mm before it attaches to the speedometer.
      -Les S.
