Title: XR200 questions.
Post by: Nathan S on July 18, 2013, 08:10:26 pm

1. Anyone aware of a significant lighting coil upgrade for a two-valve XR200?

Somewhere around 100W DC would be good.

2. Can they be geared to be (relatively) comfortable at 100kph without being a gutless wonder on hills?

3. Can an 18" rim be fitted?

4. Basic path for performance upgrades?

All I can tell is that I rode one at Three Bridges earlier this year (thanks to poppy) an was suitably impressed! Yeah it needed full throttle everywhere but besides that I don't think I was any quicker around the loop on my IT200, to which I was quite surprised.

       My 83 model 200 has an 18" rear wheel in it stock i think the xl 185 wheel will
       go strait in .
       I went to a 48t rear sprocket to make it a bit better in top if you go too big in
       sprocket sizes you will make 1st gear too high as well as they are a pretty close
       ratio box if you check it out the xl185s gear cluster will go in and its a lot wider
       ratio's than a 200 box

My experience last year with an XR200 '82 indicates that if you take 100W out of the engines output for lighting and gear it for an 'easy' 100kph cruising speed it would not matter what size wheel it has because it will not move at all :P :P :P ::) ::) ::) maybe the 4 vavers would be better ???

the joy about an XR 200 is that you just hold it flat and hang on, muscling it around corners on momentum only as there is no power for acceleration. yep they will do 100Kph just takes a while to go from 70 to 100

Run it down the road at 10,000 rpm and see small coil rewinds in geelong for more candlepower at t he front

remember, if its pushes a stronger light beam out the front, the recoil will slow the bike down when you flick the light on.... ;D :D

Cheapest performance upgrade is to zip-tie the throttle open Nathan. Neat bike for bush bashing.
