  1. Hi,
    This is my first thread and I'm probably the most inexperienced rider on this forum. I owned a Honda XL250 about 30 years ago and put less than 1,000 kms on it. Otherwise it's just been day hires of small bikes in exotic tropical locations around the world.
    On my bucket list is a ride up to the Himalays. I commissioned a Vespa and an Enfield in Delhi last year but after my deposit was handed over and I left the country the guy didn't answer one email. Its a long storey but I got my deposit back a couple of months ago.
    A couple of days after I put down the deposit and on my last night in Delhi I was on the street after the bar closed and spoke to some people, one of whom is a bike customiser. Another long storey cut short - he is now building a bike for my planned trip to the Himalayas.
    I'm hoping to get some help from the seemingly very generous people on this forum so my first question is that I have the choice of fuel injection or carby. Normally I'd jump at the chance of fuel injection - it's basically a Royal Enfield 500cc that's getting built - but I'm being advised to take off the already fitted injection and go to carby for my trip to the Himalayas. I'm told that the carby will be highly tuneable (by me after a half day course) for the high passes.
    What advice can you folk give me on my alternatives?

  2. I would have thought efi would be a lot better. The o2 sensor in the exhaust can monitor the ratios and adjust the fuel delivery according.

  3. Check xbhp.com forums.

    It's the Indian version of Netrider and there are plenty of threads on himalayan trips. They include countless pictures, tips, local information and more.

    Lots of forum users take the trip to Ladakh and Leh along various routes. They are very helpful and you could probably meet up some of them along the way.

    ROYAL Enfield, KTM, Pulsar, you name it, these guys have taken it to Himalayas. One guy even did the whole trip on bloody scooter.

    And welcome to NR...

  4. The domestic RE doesn't have an O2 sensor. I'd still keep the EFI though, everyone rides them up into the Himalayas in stock form.

  5. A few more things:

    The on board electronics have a self diagnostic capability, you can ground out the diagnostic wire and the CEL on the dash will flash in a sequence that will tell you what's wrong.

    I haven't been up in the Himalayas but I'm led to believe that you'll have to fuel up from some questionable sources. If you keep the EFI fitting an additional fuel filter might be prudent, or using a filter funnel or something.

  6. Depends if the ECU takes a reading from the MAP sensor on startup to determine atmospheric pressure.

    MAF and Carby both use air mass, and compensate for altitude better on the go.. to a point.

  7. I'm a long way from being an expert but I voted EFI as I'm presuming the m/c you get will have some sort of ECU to control fuel/air mixes given the mountainous terrain you'll be travelling. sounds like a great trip! are you making all bookings and arrangements yourself or are you using a travel/tour company that specialises in these trips? I am a Ulysses member and they have ads for these type of tours regularly appearing in the Riding On magazine.
  8. I'd probably go with a carb. You can still start it with a flat battery and less electronic sensors and gizmo's to play up.
    That and drag up a coupl'a yak's just in case.;)

  9. Off the beaten track wouldn't it make sense to go carby so that if you need anything done to it the locals will have more chance of helping get it sorted compared to efi?
  10. Why the Royal Enfield? Are there not better suited bikes for that?

    How much to get one here and ship it over?
  11. Did the ferris wheels thing in 2009.
    Well worthwhile. Their route was adventurous, but probably not the most adventurous. Nothing was missed though. Check their website for their route, and indeed their competition as well. They take a particular route for a reason, take heed. I know of a few people who have saved plenty by doing their own thing. I was going on my own, so th security of a group was required. Very reassuring. Mike ferris knows what he is doing, his fee was worth it for me.
    The royal enfield is not the best bike, but may be the most suitable bike because repairs and parts can be effected anywhere, even on the side of the road. Basic bike, basic repairs. Beware that they dont like being revved out, and will have problems if you redline em thru the gears. They are a putt putt style of bike, and are quite capable, but need to be ridden within their limitations, ie design parameters. They come from a more sedate era, and need to be ridden as such.
    Wont buy into the efi vs carb argument, but remember that any repairs that are needed will have to be done by someone who understands the technology. The enfield carb setups are universally known in that region. Not so sure about efi.
    If you go carbs, make allowance for a jet change as you get higher.
  12. If it's going to be a RE, I'd go (actually did go) for a carb'd model. Any mechanic in the country can do repairs for you and they're not hard to tune for the altitude as required.

    And forget the bus. The riding is incredible!
